Redesigning Marine Propellers with the Environment in Mind
Sharrow Marine, headquartered in St. Clair Shores, Michigan, is focused on marine propulsion technology. In 2024, the company’s Sharrow Propeller™ was recognized as a finalist in Fast Company’s Best World Changing Ideas North America award category. The awards honor businesses and organizations that are developing creative solutions for “the most pressing issues of our time.” SBND recently interviewed Greg Sharrow, CEO and inventor of the Sharrow Propeller, about the company’s technology and its impact on the environment and the marine industry. Q: Tell us about Sharrow Marine and your propellers. A: Sharrow Marine designs and manufactures propeller technology. Our propeller – recognized as the first major advancement in propeller design since the 1830s – eliminates the traditional propeller tip vortices, which are a major source of energy loss. This “tip-less” design leads to a 30% increase in efficiency and reduces underwater noise by up to 80%, making it quieter than conventional propellers. From a sustainability standpoint, this means less fuel consumption, reduced noise pollution in marine environments, and lower carbon emissions. Q: How does your propeller design directly impact sustainability in the marine industry? A: Every one of our propellers is designed for a specific application, and our process allows us to predict thrust within these applications and design for maximum efficiency. This, in turn, reduces the amount of fuel a vessel needs to operate. A lot of the fuel burned in the tanker industry, for example, is bunker fuel, which is a less refined, high-sulfur fuel. By reducing the fuel required, we not only cut carbon emissions but also reduce the pollutants entering the water. This approach creates a significant positive impact on the marine ecosystem. Q: How does the increased fuel economy of your propellers translate to measurable reductions in carbon emissions? A: The math is straightforward – burn less fuel and emit less carbon. Our propellers are about 30% more fuel-efficient, which means a corresponding 30% reduction in carbon emissions. For fleet operators and the recreational boating community, this translates to significant savings and a smaller environmental footprint. Q: What challenges did you face in developing this product? A: The biggest challenge was essentially rewriting the book on propeller design. We had to develop entirely new theories of operation and create software to test thousands of designs quickly. Assembling a team of engineers and software experts to write the code was a feat, but we now have an incredible team. Another hurdle was manufacturing. Each propeller requires its own program and a multistep production process. Finding a manufacturing partner who could handle such complexity wasn’t easy. I traveled the world and ended up finding the right partner in my backyard, which is not surprising seeing as Detroit is the place for manufacturing. We were fortunate to partner with Detroit Dynamics. They’ve been incredible in helping us establish a fully functional manufacturing facility here in Detroit. Q: Beyond fuel efficiency and emissions, what other sustainability benefits does your propeller technology offer? A: Noise reduction is a big one. The noise pollution in our oceans that is created by cavitation generated from traditional propellers has a devastating effect on marine wildlife. Our technology reduces underwater noise by 3–15 decibels on average, which helps protect marine ecosystems. Additionally, all of our materials are sourced within the United States, further minimizing our carbon footprint and supporting local economies. In terms of sustainability in Southeast Michigan, Detroit is integral to who we are. This city has a rich history of engineering and manufacturing expertise, and we’re proud to be a part of that legacy. All our propellers are manufactured here in Detroit, creating jobs and supporting the local economy. Q: What opportunities does your technology present for fleet operators and recreational boaters? A: For fleet operators, the savings in fuel costs are massive, and for recreational boaters, the benefits go beyond fuel efficiency. Our propellers reduce vibration and noise, improve high-speed control, and make docking in tight quarters much easier. For the average boater who logs about 52 hours a year, the return on investment starts the moment they turn the key. Q: How do you see Sharrow Propellers contributing to the broader efforts to decarbonize the marine industry? A: We’ve already established a strong footprint in the outboard motor market, but the inboard motor market – specifically for blue water and oceanic vessels – represents a massive opportunity. These vessels are some of the biggest polluters due to their reliance on bunker fuel. By applying our technology to this segment, we can significantly reduce sulfur emissions and improve fuel efficiency, effectively decarbonizing a critical part of the industry. We’re also partnering with VEEM in Australia to bring our innovations to the global market and are in the process of growing to full production scale of the SHARROW by VEEM. Q: Looking ahead, how do you see your propeller technology fitting into broader sustainability efforts? A: We’ve been focused on the marine industry, but interestingly, the propeller was originally developed for use in the air. So, as we move forward, expanding into renewable energy applications is a priority. Whether it’s wind turbines, hydro-energy, or further innovations in marine propulsion, our goal is to make a meaningful impact on how energy is generated and consumed.

RE-TREE Creates a Marketplace for Property Owners to Preserve Mature Trees
RE-TREE is a for-profit digital marketplace designed to offer property owners a more responsible alternative to traditional healthy tree removal. The platform enables property owners to sell, relocate, or donate their trees, promoting sustainability and preservation. Transplanting services supporting the marketplace are provided by a network of certified and trained contractors, ensuring professional and reliable execution. A detailed proposal for these services is presented to the buyer, approved, and collected by RE-TREE upon project completion. In addition to transplanting services, RE-TREE offers plant healthcare solutions designed to enhance the growing environments of mature trees. These services focus on improving the health span of trees, ultimately contributing to their longer lifespan. The marketplace operates as a virtuous cycle, with tailored approaches for residential and commercial property owners. A transaction fee applies to the appraised value of the tree: For residential property owners, fees range from 20-30%, depending on the appraised value of the tree. For commercial property owners, a flat 20% transaction fee is applied. RE-TREE bridges the gap between environmental responsibility and practical solutions, creating value for both property owners and their communities. SBN Detroit sat down with RE-TREE’s founder and CEO, Dennise Vidosh, to discuss the urban and suburban landscaping waste challenges in Southeast Michigan, the economic and environmental impact of saving mature trees, and how these efforts are contributing to broader climate action goals. Q: What is the impetus behind RE-TREE? A: As a little girl, I was deeply connected with nature, and I wanted to preserve the beautiful environment I grew up enjoying. My purpose materialized in 2018 with the innovative vision of preventing the unnecessary destruction of mature trees by developing a digital marketplace for their relocation. Through the power of technology, RE-TREE provides a platform for property owners to buy, sell, and relocate mature trees, turning a potential environmental loss into economic and ecological gain. This initiative is a solution to a global issue, transforming private property landscaping practices and redefining urban sustainability. Our momentum is driven by two key forces: the era we’re living in—commonly referred to as the Anthropocene, where we are acutely aware of our impact on the environment— and the green industry’s growing capacity and enthusiasm to embrace innovation and prioritize ecological preservation, setting the stage for meaningful change. Q: What are the current challenges facing Southeast Michigan in terms of managing urban and suburban landscaping waste, and how significant is the problem? A: One major challenge is a lack of awareness—awareness that a responsible solution exists when a tree outgrows its space or is in the way of new construction. Another challenge is perception. We’ve encountered some pushback from municipalities that don’t yet believe our tree preservation goals align with local ordinances. However, we’re actively working with these municipalities to find solutions, turning skeptics into our strongest advocates. Mature tree preservation is our mission, and while trees in commercial green spaces have historically followed a linear lifecycle, we’re making it cyclical to extend their lifespan and environmental contributions. Q: How does the concept of replanting trees and bushes instead of discarding them align with broader sustainability goals? A: Relocating mature trees rather than removing them aligns seamlessly with global sustainability goals. Mature trees provide exponential benefits to our planet, people, and communities. When healthy trees are removed simply because they’re in the way, all those benefits are lost. RE-TREE connects the dots through technology, making it easy for property owners to take a more sustainable approach. Once a mature tree is cut down, we can never replace its ecological value by planting smaller, less mature trees. Protecting these trees ensures a continuous cycle of giving back to the environment. Q: What are the environmental impacts of saving and replanting trees compared to traditional disposal methods? A: Once we destroy a mature tree, we can never catch up to the value it provides—both now and in the future. Growing trees as an agricultural crop on open land isn’t sustainable either. Preserving existing mature trees ensures we maintain their current environmental benefits, which include carbon sequestration, oxygen production, cooling effects, reduced erosion, and providing habitats for biodiversity. Q: What are the key requirements for a tree or bush to be successfully salvaged and replanted? A: The tree must be free of damage or disease and accessible for responsible extraction. There must be no overhead wires obstructing its removal path, and it needs to be a certain distance from any structure, depending on its size. Generally, we work with trees under 12 inches in trunk diameter or 35 feet tall. Bonus points for unique shapes or styles! Q: What are some of the biggest logistical or operational challenges in implementing a tree-replanting program? A: Building a network of certified service providers is currently the most significant challenge. Attracting, training, and certifying contractors to move living organisms responsibly takes time. The supply of trees will drive the demand and attract contractors, creating a new revenue stream for green industry professionals while enhancing their environmental stewardship. It’s a process of “build it, and they will come.” Together, we can build this supply chain and revolutionize the industry. Q: What are the economic and environmental benefits for homeowners, developers, or municipalities who choose to salvage trees and bushes instead of removing and replacing them? A: The benefits are immense. A mature tree sequesters eight times more carbon produces eight times more oxygen, and provides vital habitats for countless species, contributing significantly to biodiversity. These trees are invaluable to the planet’s ecosystem, and their preservation actively mitigates climate change impacts. Municipalities can benefit from residents or businesses donating trees to local parks, while commercial property owners can transform their green spaces into revenue-generating assets. It creates a never-ending cycle of giving back, fostering community connection and shared environmental goals. Q: How does preserving trees contribute to broader climate action goals, such as reducing greenhouse gas emissions or improving biodiversity in Southeast Michigan? A: Preserving carbon sequestration benefits is the most immediate and obvious impact. By advising

Safe Water Engineering – Tackling Water Safety in Southeast Michigan
Southeast Michigan faces significant challenges in water infrastructure and safety, particularly in addressing aging systems, lead contamination, and ensuring equitable access to clean drinking water. Safe Water Engineering LLC, a Detroit-based consulting firm founded by Elin Warn Betanzo, focuses on improving access to safe drinking water through engineering and policy solutions. As the architect behind Detroit’s lead service line replacement program, Betanzo has played a key role in improving water safety in the region. The city has replaced over 11,000 lead service lines since 2018, providing safer drinking water to thousands of residents. Beyond infrastructure, Betanzo’s work also focuses on water safety and affordability policies. SBN Detroit had the opportunity to interview Betanzo regarding the challenges and opportunities surrounding water management in Southeast Michigan, the lead pipe replacement efforts, and the steps needed to ensure sustainable and equitable access to clean water. Q: What is the impetus behind Safe Water Engineering? A: I started Safe Water Engineering in 2017 after the Flint water crisis revealed a critical need for specialized expertise in lead and drinking water safety. Our work focuses on helping water utilities meet and go beyond compliance requirements for drinking water safety and supporting communities by providing access to data, information, and education. Q: Can you tell us more about the city’s lead service line replacement program you designed and your work in drinking water policy? A: From 2017 to 2020, I worked with the Detroit Water and Sewerage Department (DWSD) to design the city’s lead service line replacement program. At the time, it wasn’t a regulatory requirement, but Detroit wanted to take a proactive approach. My work involved developing procedures for conducting lead service line replacements, incorporating replacements into broader infrastructure projects, conducting outreach to residents, and ensuring safety during replacements – like providing filters and flushing instructions. We also created a comprehensive program outlining responsibilities, timelines, and costs. The program is now underway, and the city has committed to replacing all lead service lines within ten years. Q: What are the biggest challenges communities in Southeast Michigan face in ensuring clean and safe water? A: Southeast Michigan’s water infrastructure relies on the backbone of water and sewer mains that Detroit built during the last century. It was designed and constructed for the time when it was built – a different population distribution and climate conditions than we have now. Over time, the region has faced significant changes, including population shifts, aging infrastructure, and climate impacts like altered precipitation patterns. Key challenges include the need to renew and replace aging water mains, sewer systems, and lead service lines, many of which were installed during the first half of the last century. Additionally, when water rates were set in many communities, they did not account for the necessary infrastructure renewal costs especially when they relied on existing infrastructure to expand. This becomes a challenge when we see this multitude of issues and challenges coinciding. It is essential to ensure public health protection is maintained as a top priority while developing water affordability programs to ensure everyone can afford access to that protection. Q: How has climate change impacted water systems in the region, particularly with issues like flooding, stormwater management, and aging infrastructure? A: The magnitude and frequency of extreme rainfall events have increased significantly in recent years, with Southeast Michigan experiencing multiple 100-year storms within a five-year span. The current infrastructure was not designed to handle such high volumes of water, leading to challenges like stormwater runoff overwhelming wastewater systems, and causing untreated releases into the Detroit River and Lake St. Clair. Additionally, urban development has created more paved surfaces, increased runoff, and disrupted natural drainage systems. This combination has led to significant flooding issues, further straining aging wastewater and stormwater systems. Q: Why are lead service lines a concern, and what is being done to address them in Southeast Michigan? A: In Michigan, community water systems were required to report the potential presence of lead service lines to the state in 2020. Statewide, up to 26% of these systems may have lead service lines, with Southeast Michigan particularly affected. For example, Detroit alone has up to 108,000 lead service lines, and potentially twice as many may exist in the surrounding communities. When water – although treated with corrosion control at treatment plants – passes through leaded materials, lead is frequently measured at the faucet – the point where it becomes drinking water. Lead in drinking water poses a significant health risk, as it is a neurotoxin with no safe level of exposure. Michigan was the first state that required mandatory lead service line replacement, mandating the removal of all lead service lines by 2041. A new federal rule accelerates this timeline nationally, requiring removal by 2037. Utilities are also required to notify residents if their home has lead pipes, enabling them to take precautions like using certified lead-reducing filters, which are highly effective when properly maintained. Q: What are the challenges involved in making Southeast Michigan’s drinking water safer and more affordable? A: Unlike housing, food, and electricity, Michigan lacks a statewide water affordability program. Rising water rates to fund infrastructure upgrades have made water unaffordable for some households, despite the public health necessity of these investments. There are programs like the Great Lakes Water Authority’s WRAP Program and DWSD’s Lifeline Plan, but the need for support exceeds the current resources available. Legislation to create a statewide water affordability program is under consideration, but challenges remain in addressing the broader affordability gap. Q: What strategies or technologies are being implemented to address lead contamination, and what additional steps are necessary beyond lead pipe replacement? A: Lead service line replacement is critical, but residents don’t have to wait for this to happen to reduce their exposure to lead in water. Certified lead-reducing filters are available and highly effective, provided they are properly maintained. Public education is essential to ensure residents understand the risks and how to take action. Additionally, programs like the Michigan Department of Health
Beacon Manufacturing – Supporting LEV Innovation at Newlab
Newlab at Michigan Central is home to a new 10,000-square-foot center for manufacturers of light electric vehicles (LEVs) – two- and three-wheeled vehicles mostly used for short distances, such as e-scooters and e-bikes. The center, dubbed “BeaconLab,” is operated by the newly created Beacon Manufacturing and will operate as a prototyping and logistics services manufacturing consultant, coordinator, and manufacturing hub for startups. It is equipped with several bays of assembly stations and state-of-the-art advanced machinery for robotic wheel building, laser-tube cutting, and robotic welding, to accelerate startups’ journey from concept to scale. The company leases the space from Newlab and is paid a fee for service by clients. Beacon Manufacturing also owns the Detroit Bikes brand, which it purchased in May from Cardinal Cycling Group. SBN Detroit interviewed CEO Gary Thornton, who previously was general manager of Detroit Bikes, about plans for the center, trends in LEV mobility, and other topics. Q: Beacon Manufacturing is focused on prototyping and logistics services for light electric vehicle (LEV) manufacturers. Explain what this entails. A: Our work at Beacon Manufacturing is twofold. First, we focus on prototyping, helping startups move from concept to tangible products. We take initial designs and create physical prototypes, allowing companies to refine their ideas and demonstrate proof of concept. The second part involves logistics services, acting as a third-party logistics (3PL) provider. We rent warehouse space specifically tailored for LEVs. Our team manages everything from storing products to shipping them out, ensuring each vehicle is operational before it leaves the facility. This includes handling specific challenges related to LEV batteries and ensuring compliance with regulations. Q: What types of companies and vehicles do you work with? A: We primarily collaborate with companies focused on last-mile delivery solutions. These startups are experimenting with new vehicle designs – e-scooters, e-bikes, and even electric tricycles – to solve urban transportation issues. One example of our work is with Civilized Cycles, a Newlab-based startup developing an e-bike with a tricycle and trailer attachment. Their solution addresses congestion in cities like New York, where specific zones impose fees on larger vehicles. Using a smaller LEV, they can transport goods efficiently without contributing to traffic or emissions. Q: What is the market potential for LEVs? A: The LEV market is massive and largely untapped. The need for efficient, low-emission transportation in urban areas is growing rapidly. We’re seeing interest from companies large and small, all looking to shift away from traditional vehicles. Cities like New York, Paris, and others are exploring ways to reduce congestion and improve air quality by shutting down portions of the city to standard vehicles or charging usage fees. LEVs fit perfectly into this evolving landscape, providing a practical and sustainable solution for short-distance travel and deliveries. Detroit’s ecosystem is ideal for LEV development with its roots in automotive design and manufacturing. Within a 20-mile radius, you can find suppliers for almost any component. We are working on LEVs as mentioned to address the last mile of delivery or traffic congestion, and we are currently working on an extremely rugged LEV that can be used to deploy power grids remotely for farmers and everything in between. There is a constant quest to come up with ideas to push the limits within Newlab and Southeast Michigan. Q: What challenges do LEV manufacturers face when scaling production? A: The biggest hurdle is cost. Traditional auto suppliers aren’t set up for small runs, so startups often face prohibitively high quotes. We are set up to focus on the individual manufacturing processes and tailor solutions to their scale. Another challenge is managing expectations. Many entrepreneurs want a final product that’s perfect, but early prototypes need to prioritize function over aesthetics. Our role is to guide them through this process, ensuring they have a viable product to show investors or test in the market. Q: What types of collaborations do you facilitate, and how do these impact LEV development? A: We enable companies to focus on their core strengths, such as design and marketing, by handling their logistics, manufacturing, and shipping needs. Currently, our warehouse hosts four electric motorcycle brands, two e-bike brands, and even an electric snowmobile company. These collaborations foster a supportive environment where different players in the LEV space can learn from each other, share resources, and accelerate their growth. Q: How do you see the LEV market evolving in the next 5–10 years, particularly in Southeast Michigan? A: The LEV market is poised for explosive growth, much like the e-bike market has experienced. The acceptance of battery-powered tools and vehicles is spreading quickly. From electric lawnmowers to chainsaws, we’re seeing a cultural shift toward cleaner, more efficient technologies. In Southeast Michigan, the manufacturing expertise built over decades in the auto industry provides a strong foundation for LEV innovation. Detroit is uniquely positioned to become a hub for LEV development and production. Q: How has Newlab enhanced Beacon Manufacturing’s ability to innovate and scale?

The state-of-the-art machinery and resources available here – CNC (computer numerical control) machines, cleanrooms for electronics, woodshops, and metal shops – allow us to tackle complex manufacturing challenges. The collaborative environment also plays a crucial role. Being part of a community of innovators means we’re constantly learning and pushing the boundaries of what’s possible in LEV manufacturing. What are your plans for BeaconLab as it relates to the LEV industry in Southeast Michigan and beyond? A: We’re focused on scaling our operations to meet the growing demand. At Newlab, we’ve set up five fully stocked workbenches that startups can rent to assemble their vehicles. This hands-on space allows entrepreneurs to bring their concepts to life. Additionally, we’re expanding our offsite facilities to accommodate larger manufacturing runs. Our new 20,000-square-foot warehouse will support startups ready to scale from prototypes to larger production runs of 100 or even 1,000 units. Also, I’m extremely optimistic about Detroit’s future in this space. The city’s deep manufacturing expertise, coupled with the growing demand for
Technology-Driven Air Quality Monitoring Gains Traction in Detroit
JustAir, a Detroit-based startup cofounded by Darren Riley leverages data and technology to provide hyperlocal air quality insights, largely in urban areas. By deploying a network of air monitors, JustAir delivers real-time data that communities, policymakers, and environmental justice groups can use to push for meaningful action. With funding from initiatives that include Google for Startups Black Founders Fund, the company is building systems that aim to transform how cities like Detroit manage air quality challenges. SBN Detroit interviewed Riley to learn about the broader implications of air quality monitoring, the challenges of implementing these systems, and how accessible data can drive public health improvements and policy changes. Q: Why is air quality monitoring critical in urban environments like Detroit? A: Detroit has a history of industrial pollution and high traffic volumes, especially in areas like Southwest Detroit, where I live. These factors contribute to some of the worst asthma rates in the country. Traditionally, air quality data has been collected on a regional level, offering only a broad overview. But air pollution isn’t uniform across a city – it can vary dramatically from one block to the next. Localized data helps us understand where the worst impacts are happening, who is most affected, and when conditions are at their worst. This kind of granular information is essential for designing targeted interventions going forward. Q: How does air quality monitoring technology work? A: Traditional air monitoring relies on a handful of monitors spread across a large area, often providing limited insights. Our software facilitates and integrates multiple air monitors within a single area, sometimes scaling up to 50 or 75 units. These monitors collect data in real time, creating a detailed picture of air quality at a hyperlocal level. We don’t manufacture the monitors ourselves – we work with partners to deploy them. Our software acts as the brain, aggregating data and managing the network. The idea is to provide actionable insights that can help residents, and, also down the road, policymakers and stakeholders in cities like Detroit better understand their air quality challenges and begin to determine how to better manage them. Q: What is an example of your work in Southeast Michigan? A: We have a three-year contract with Wayne County, which, before this partnership, had just seven or eight monitors managed by EGLE (Michigan Department of Environment, Great Lakes, and Energy). We added 100 monitors across the county so now every community has at least one monitor. Residents can sign up to get alerts – they can subscribe to individual monitors in their area or around a particular school or place of worship, etc. They can set when they want to receive alerts. This is a customizable service and it’s free – anyone can visit JustAir.app/signup right now and sign up to receive those alerts. The county Department of Health Human & Veterans Services is our lead partner on this project and they’re diving into the data to better understand the air across the community. They’ll be able to use this information to improve the health, safety, and well-being of county residents. Q: What unique challenges do urban environments like Detroit face in addressing air quality? A: Urban air quality is influenced by a combination of mobile sources – like cars and trucks – and stationary sources, such as factories. Detroit’s high traffic volume, especially near international border crossings, adds to the problem. Wind patterns also play a role; on certain days, pollution can settle in specific neighborhoods, exacerbating the issue. Q: How does technology, particularly AI, help address these challenges, and what opportunities do you see for the future? A: Currently, we leverage AI to ensure the validity and accuracy of our data. This is crucial for providing communities with reliable information. We’re now moving into the next phase, where we aim to use AI to recommend actionable solutions for mitigating air quality issues. AI allows us to dig deeper into the root causes of pollution. It helps us analyze data patterns—such as specific pollutants, weather conditions, and wind patterns—to pinpoint sources of air pollution with greater confidence. By marrying environmental context with real-time data, we can provide more accurate insights. Looking ahead, the goal is to utilize these rich data sets to empower communities and policymakers to take informed action. We’re on the cusp of this now. Q: What are the challenges of deploying and maintaining air quality monitors in urban environments? A: Deployment involves hurdles like site selection, insurance, and technical logistics. Maintenance can be another challenge – we need to ensure data accuracy at all times. Our software includes an automated quality assurance system to detect and flag issues, ensuring the community gets reliable information. Q: JustAir recently received funding from Google. How will this investment be used? A: We’re one of ten companies nationwide to receive this funding, which is a great validator for us. Google conducted thorough technical due diligence, confirming that our technology is on the right track. We’re using the funding to enhance our AI capabilities, particularly in integrating contextual data with air quality metrics as I spoke about. The funding allows us to explore new solutions that can help inform and enforce public health policies. Q: How do you measure the success of your air quality monitoring initiatives? A: We have both short- and long-term metrics. In the short term, we focus on network reliability and user engagement—how often people access the data and whether they find it valuable. High engagement is a strong indicator that the information is meeting community needs. In the long term, we aim to measure health outcomes and policy impacts. For example, are asthma-related emergency visits declining in neighborhoods with high air quality awareness? Are cities using our data to implement more effective policies? Q: What does the future look like for JustAir? A: We’ve scaled significantly since launching three years ago, now partnering with 20 organizations across seven states. The future is about leveraging these networks to drive outcomes — working

Research and Innovation – I’m interested in how we can further support our existing institutes and centers that are advancing work in climate and sustainability, particularly in removing any barriers they face. Community and Impact – Michigan is in a unique position to lead on sustainability, and I want to consider how we can best advance community impact in our state. Q: Given your diverse background in policy and energy justice, how does your experience shape your approach to this new role? A: I guess I am a bit of a unicorn—having experience as a law professor, a public policy professor, and an entrepreneur. I’ve created organizations that bring community voices into complex policy discussions, which will be invaluable here. My experience in the Biden administration, working with the Department of Energy, involved coordinating scientists and engineers to advance energy justice. At U-M, I’ll be taking a similar interdisciplinary approach, working across departments and disciplines to move us all in the same direction. I know it’s a challenging role, but it builds on everything I’ve done before. Q: U-M has various departments and initiatives focused on sustainability. How will you work with these different entities to create a unified approach across campus? A: The university is known for its decentralized structure, and I appreciate the “letting a million flowers bloom” approach to innovation. I don’t want to stifle that creativity, but I do believe a central set of priorities can support and amplify the work that’s happening while offering a clear vision. I’ll be establishing an internal executive council to advise on our academic approach and to serve as a sounding board to validate and advance our goals. Another focus will be removing bureaucratic barriers that can slow down progress. Finally, I’ll be focusing on creating a clear framework that all our work can fit within. For example, I’m very excited about big, unifying concepts like “Just Transition,” which would frame our sustainability work within a commitment to equity and justice. Q: What specific goals or benchmarks are you looking to achieve in the first year or two? A: President Ono’s Vision 2034 provides an ambitious roadmap, with sustainability and climate action as key pillars. I’m excited to develop concrete metrics within that framework in partnership with our advisory council. One of my immediate goals is to position Michigan as a hub for climate action by convening conversations around the significant investment dollars flowing into the state and country. I’d also love to establish a Michigan Climate Week, hosting interdisciplinary events that bring together scholars, policymakers, and community leaders. Additionally, I’m exploring opportunities to convene global thinkers at U-M, much like the Institute for Social Research, but focused on climate solutions. Q: How will partnerships play a role in sustainability efforts under your leadership? A: Partnerships are essential. I’m meeting with other university leaders in similar roles, and I’ve spoken at places like the University of Texas and Arizona State to learn how they approach sustainability. No university can tackle this alone, and we’ll benefit from building on each other’s work. We also need strong partnerships with state government and local leaders; these relationships will be crucial to achieving our goals. Q: To that end, U-M is part of the University Research Corridor with WSU and Michigan State. What does your future work look like here, and how do you think U-M’s efforts impact this larger initiative? A: I’m excited to engage deeply with the University Research Corridor (URC). President Ono is committed to ensuring U-M is an active collaborator. Climate and sustainability are areas where we can work together effectively, especially with the influx of investment dollars Michigan is seeing for climate-related projects. The URC offers a platform for a coordinated approach, allowing us to make a more substantial impact across the state and lead in this area. Q: How will the university’s Innovation District in Detroit factor into U-M’s sustainability and climate action goals? Could this space serve as a model for sustainable urban development? A: The Innovation District in Detroit is a promising opportunity, though it’s still in the early stages. Detroit is undergoing incredible changes, and with my background in energy justice, I’m very interested in how this district can address both environmental and socioeconomic challenges. This area could become a prime example of how clean energy initiatives can drive economic and social transformation in cities that have historically faced challenges.
Ecosphere Organics on Advancing Sustainable Biorefining
Ecosphere Organics, cofounded by Brittanie Dabney, is focused on innovating within the sustainable biorefining industry. By leveraging advanced technologies, including artificial intelligence, the company aims to address critical challenges in resource recovery and material processing. The goal is to simplify the biorefining process, enabling companies to focus on developing sustainable end products rather than managing complex material recovery operations. Ecosphere is finalizing logistics and has run pilot programs, working toward launching with clients. SBN Detroit interviewed Dabney to learn more about the mission and technology behind Ecosphere Organics, the challenges it faces, and the opportunities she sees within the industry. Q: What is the driving force behind Ecosphere Organics, and what key problems does it aim to address? A: Our driving force is the urgent need to reduce the environmental impact of food and organic waste. Our goal is to help companies transition toward sustainable production practices by diverting valuable food waste from landfills and giving it a new purpose. Today, food waste is often simply discarded or composted, but there are many untapped opportunities to extract value from it. By refining food waste into components that can be used in industries like textiles, packaging, and bio-based chemicals, we can give companies the tools to be more sustainable while contributing to a circular economy. Q: What do these applications look like? A: Today, we focus primarily on pre-consumer waste, meaning clean food waste from sources like restaurant kitchens. This includes citrus peels, eggshells, coffee grounds—essentially, anything that hasn’t been contaminated by being on someone’s plate. By working with clean streams of waste, we can efficiently sort and sterilize the materials, which makes them ideal for biorefining. Take banana peels, for example. We can extract natural pigments from these peels, which can be used as dyes in the textile industry. Fibers from the banana stems can serve as fillers to reduce plastic content in consumer goods, and food-based fibers are also being explored as eco-friendly options in packaging. Right now, we’re focusing on converting food waste into powders that can be further refined for green chemicals, substrates for fermentation processes, or even bio-based fertilizers. Our approach is about seeing the full lifecycle of organic waste and giving it renewed purpose. Q: What work have you done to date? A: We officially launched in March 2024, and our early work has been focused on refining recipes for our material blends, bioplastics, and processes to scale. Right now, we’re working on logistics – figuring out how to streamline the collection of food waste suitable for urban areas, how to efficiently transport it to our location, and how to make it as easy as possible for food suppliers to collaborate with us. To that end we will be participating in a pilot program with Orange Sparkle Ball and Intermode, where there will be an autonomous robot to collect waste in Corktown and transport it to Ecosphere. By reducing reliance on diesel fuel trucks, this approach lowers emissions and makes the entire lifecycle of our raw materials more sustainable and cost-effective. Collecting waste locally not only supports a more efficient supply chain but also allows more businesses to join the bioeconomy in a sustainable way. Q: How do you leverage AI and how does this technology optimize the process? A: The biggest opportunity lies in scalability and efficiency. Advanced technology and AI will allow us to optimize everything from waste collection and processing to customized material selection. With these tools, we can better predict waste volumes, design adaptable systems, and improve the quality of the materials produced. AI in biorefining enables smarter, more sustainable processes that can be replicated across various regions and industries, supporting a broader shift toward a circular economy. AI also plays a role in educating companies. We can recommend specific applications for raw materials, such as high-quality pigments, bio-based fertilizers, or even bioplastics. AI will help predict material demand and recovery rates, which allows us to guide companies toward the best ways to integrate sustainable materials into their products. Our platform will also serve as a resource for companies involved in R&D or prototyping, providing valuable data on material properties and potential applications. Q: What are some of the biggest technological challenges you face? A: One major challenge is creating processing systems flexible enough to handle diverse organic waste streams. For example, different types of citrus peels—like oranges, lemons, and limes—often need to be manually separated before continuing the refining process. Designing a system that can automatically adjust to these varying feedstocks is complex, but we’re actively working on solutions. Another challenge is the inherent variability in organic waste itself. Restaurants source ingredients from different locations, resulting in diverse nutrient profiles. Designing systems that can consistently process this range of materials while maintaining the quality of the end product is a technical hurdle. Finally, ensuring the quality of our end materials is crucial. Integrating data into our platform to monitor and adapt our systems will be essential to maintaining the high standard we are aiming for across all processing operations. Q: Are there specific partnerships or collaborations in Southeast Michigan that you’re working on? A: We’ve built partnerships with local restaurants, food service providers, urban farms and composters such as Sanctuary Farms. We also collaborate with other tech providers like Orange Sparkle Ball for waste collection solutions. Additionally, we’ve partnered with educational institutions and nonprofits like Make Food Not Waste, Black Tech Saturdays, Wayne State University, and the College for Creative Studies. For example, during Detroit’s Month of Design, we hosted “Waste to Wonder,” a community-centered and educational event where artists used pigments derived from food waste to create art. We’re also hoping to work more closely with the City of Detroit and other municipalities, with the goal of integrating our biorefining systems into broader sustainability strategies. Q: What obstacles do companies face in adopting sustainable biorefining, and how do you help overcome them? A: One major obstacle is the perception that sustainable practices are prohibitively expensive or difficult to
Restoring Detroit’s Tree Canopy
Detroit was once known as the “city of trees,” but disease, invasive insects, and budget cuts over time have decimated our area’s distinctive tree canopy. But efforts are underway to replenish trees while also providing job training, green spaces, education, and community engagement. On Oct. 31, 2024, Sustainable Business Network Detroit hosted an informative discussion sponsored by the Fred and Barbara Erb Family Foundation regarding these efforts and how restoring tree canopy benefits individuals, neighborhoods, businesses, and the economy. The panelists were: Lionel Bradford, president and executive director, Greening of Detroit, a nonprofit focused on enhancing the quality of life for Detroiters by planting trees, providing job training, and involving youth in the education of the natural environment. It involves Detroiters in the process through community engagement, green spaces, education, and jobs. Maureen Donohue Krauss, president and CEO, Detroit Regional Partnership. DRP works to serve as a single point of contact for information, connection to services, incentives, and data for businesses who want to locate or expand in the 11-county Southeast Michigan Region. Robert Riney, president and CEO, Henry Ford Health, and leader of HFH’s $4 billion Destination: Grand initiative. The project includes a $2.2 billion expansion of HFH’s Detroit campus anchored by a new state-of-the-art hospital facility that will span 1.2 million square feet. It includes a 20-story patient tower, with three floors dedicated to providing intensive inpatient physical medicine and rehabilitation in partnership with the Shirley Ryan AbilityLab and its own Central Energy Hub, making it one of the largest fully electric-capable hospitals in the country. The event was moderated by Terry Barclay, president and CEO of Inforum, and chair of SBN Detroit. Some of the takeaways: The case for tree canopy Lionel: Growing up in Southeast Louisiana – which is very hot – you quickly learn the value of a tree. It’s also a sportsman’s paradise – We did a lot of hunting, fishing, and camping, and I developed a great appreciation for the environment and its value. I also love people. The work that we do is about people at the end of the day, so when we do this work it’s to build community and neighborhoods. We try our very best – changing landscapes and lives is our motto. When someone has been incarcerated for 20 years and needs a second chance, they can come through your program – the Detroit Conservation Corps – and they can be trained and support their families. You can train people to put trees in the ground and maintain them. Maureen: Part of my role is to inform people that economic development is more than just a new factory in your town, more than just a tax abatement. It’s creating an environment that both people and companies want to be in. Sixty percent of our projects are from international companies – when people come here for the first time, they have expectations of what a first-class city looks like… Think about Paris and its phenomenal tree canopies. People want that here. I did a little research before this event: Homes with trees sell two days faster and for 15% more than homes without. Tree value increases with age – the cost of trees has 100% payback. Three properly placed trees can reduce air conditioning by 56% and reduce home heating bills by 10% by serving as a windbreak. Bob: You may think what does a healthcare system have to do with tree canopies? HFH is absolutely committed to increasing the health of communities – the role that hospitals and doctors play is about 20%. We don’t underestimate the power of that 20%, but true health – meaning how long people will live and have a high-value life – is a partnership of healthcare, policy, and environmental factors – which are huge. You may have seen that the biggest determinant of your health is the ZIP Code that you live in. You need to have fabulous healthcare, access to it, economic security, environmental security, and food and nutrition security. At HFH we need to be a population health company – we pick and choose how we should make our mark and one of the things we believe in is the power of the tree. We have to walk the talk. The economic benefits of tree canopy Maureen: Our organization has three pillars: market, grow, and support. It’s so much better now. People are curious to hear about Detroit and see what’s happening. Talent is No. 1 – we have the second-highest amount of engineers in the country and have experienced manufacturing talent. As one of my teammates says, it’s workforce, weather, and water. When you talk about climate change, Michigan will be in the top five least affected. The right amount of tree canopy and how trees are sourced Lionel: American Forests did a study and determined that a city the size of Detroit should be at 40%. Right now we’re at 26%. We lose about 2,000 trees a year, so those have to be taken into account. We get most of our trees from New York and Indiana and, more recently, Wholesale Tree Inc. in Northern Michigan. More importantly, we’re growing our own trees now – running the Walter Meyers Nursery in Rouge Park, which is owned by the city. We’re very intentional about turning into a full-fledged operational business. Last year, we harvested our first set of trees. We have lost a lot of trees over time, and the reason we have lost a lot of those is because the city lacked the resources, and dead trees were not removed and were taken down by storms. This administration has done a great job by taking trees down when dead and dying. Working with DTE has been quite thrilling – they have given financial support to planting trees but also to making sure that the next generation of environmental stewards are trained by supporting our Green Corps summer programs and also the tree
THRIVE Collaborative’s Approach to Sustainable Development
THRIVE Collaborative is an Ann Arbor-based real estate development, design, building, and consulting firm dedicated to creating life-enhancing, grid-interactive buildings that harvest their own energy and water, create zero waste, and are beautiful and restorative. Its current project – Veridian at County Farm in Ann Arbor – is a 100% electric development, powered by solar with no gas lines or combustion appliances. It is targeted to be one of the nation’s first mixed-income net zero energy communities. SBN Detroit interviewed Matt Grocoff, THRIVE Collaborative founder and lead on the Veridian project, to find out more. Q: How do you approach creating buildings that harvest their energy and water and create zero waste, and how long have you been doing this work? A: Thrive Collaborative approaches sustainable development by aiming to create buildings and communities that align with what is necessary for the future. Our flagship project, Veridian, is a model for addressing pressing climate challenges. When we started Veridian in 2016, we were guided by the goals of the Paris Agreement, which sets a target of keeping global temperature increases below 1.5 degrees Celsius. This means eliminating fossil fuels and using only renewable energy to power buildings. I see Veridian as an act of optimism. It is a 100% all-electric community, with no gas or fossil fuels. It’s powered entirely by on-site renewable energy, including solar panels, battery storage, and geothermal systems. Every home in the development produces more energy than it consumes, ensuring it is not only sustainable but capable of energy storage for future use. The idea is to show that what we need to do for the planet can also create a beautiful and socially just way of living. Q: In your experience, what are the biggest challenges in integrating sustainable practices into real estate development in Southeast Michigan? A: One of the biggest challenges we face is that there is no existing template for what we are trying to accomplish. The science of sustainability is clear, but the regulatory framework, building codes, and conventional construction practices in the U.S. don’t match what we are trying to achieve. Veridian uses a specific permeable road surface called Ecoraster. This is an eco-friendly, flexible, porous paver made from 10% post-consumer and post-industrial recycled plastics. However, the material was initially rejected by the city. We had to prove it met the necessary standards, which took nine months to do. This is one of dozens – maybe hundreds of examples of outdated building codes and policies that just don’t align to support the materials and practices we are employing. There are also challenges related to training contractors and tradespeople in new, sustainable methods. Q: How have you navigated these challenges? A: The key is to approach it knowing that sustainable development is both necessary and possible. There are always people who say, “That’s not how construction is done,” but that resistance creates an opportunity for innovation. Q: What role does Veridian play in the broader sustainability movement in Southeast Michigan, and what are your long-term goals for this project? A: At a micro level, Veridian Farms is about creating a model neighborhood that implements the necessary solutions for sustainability. The project serves as a case study for what’s possible when we fully embrace renewable energy, energy efficiency, and zero-waste practices. At a macro level, the goal is to demonstrate that these methods can and should be replicated across Southeast Michigan and beyond. The science is telling us that we need to cut global carbon emissions in half by 2030 to prevent the worst impacts of climate change. By showing that this level of sustainability is possible today, we hope to inspire policymakers, developers, and financial systems to support and scale these efforts. Q: What are the economic implications of building sustainable communities like Veridian? A: There’s often a misconception that building sustainably is prohibitively expensive, but that’s not the case when you take a holistic view. While technologies like geothermal heating and certain types of appliances might cost more upfront, they pay off over time. Solar panels, for example, lock in energy costs for 30 years, which is far more economical than relying on fossil fuels, whose prices fluctuate. When we look at costs holistically — factoring in the environmental impact of conventional practices — sustainable building becomes the more affordable option. We must rethink what “cost” means, not just in terms of the price of materials but in terms of the long-term health of the planet and the people who live in these homes. Q: What is the timeline for Veridian? A: We proposed the project in 2016. It took a couple of years to get approved. We are almost to year nine and we have our first residents living there now. The renewable energy systems are up and running and every home is producing more energy than it uses. Homes are heated and cooled with energy provided by the sun. Instead of storm drains, we have bioswales and butterfly gardens and birds and plants. We engineer using plants and pipes, but we use natural systems to operate more elegantly than the conventional expensive, and unsustainable storm drain systems. By the end of the year, we’ll have all residents moved into our first sequence, which is 21 single-family homes. By early next year, we’ll have another ten two-bedroom lofts occupied. Q: What are some of the lessons you’ve learned from past projects that are helping guide future developments? A: All innovative projects are learning opportunities. One major lesson is the need for a significant shift in the American construction industry. Compared to Europe, where sustainable building practices are more advanced and efficient, the U.S. lags in terms of both financial structure and the materials used. We also need to address the utter lack of diversity in the trades—something Europe has done more effectively. We’ve also learned that collaboration is critical. Whether it’s working with local governments to navigate building codes or partnering with vendors to source sustainable materials, the
