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

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.

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
Tackling Water Infrastructure and Coastal Challenges in Michigan
Ann Arbor-based CIS was founded in 2013 by Corvias, a Rhode Island-based company that provides infrastructure services to the military, state and local governments, and higher education. In 2023, it was spun off as an independent company whose services center on solving the complicated challenges of outdated and ineffective stormwater infrastructure. SBN Detroit interviewed the company’s CEO, Sanjiv K. Sinha, Ph.D., and Sri Vedachalam, Ph.D., Senior Director of Water Equity and Climate Resilience, about two recent projects – an advisory and research project focused on coastal conservation for The Nature Conservancy, a global conservation nonprofit, and an analysis of Great Lakes Regional Poll (GLRP) data for a binational federal agency. Q: What were the primary goals of the coastal conservation analysis services you provided for The Nature Conservancy? Vedachalam: The main goal of this project was to conduct a comprehensive scoping exercise to identify and understand the key challenges faced by Great Lakes communities in relation to fluctuating water levels, high-energy waves, and climate-induced shoreline erosion. Shoreline erosion in particular is becoming increasingly prevalent due to climate change, and our focus was to assess how these environmental stressors impact both the natural and built environments. By gaining a clearer understanding of these challenges, our goal is to help surrounding communities become more resilient. This involves preparing infrastructure to withstand the ongoing and future effects of these changes. Q: What are the key environmental challenges currently affecting coastal areas in Southeast Michigan and the broader Great Lakes region? Vedachalam: Coastal areas in the Great Lakes region face a variety of interconnected challenges, mainly involving three key components: the lake itself, the shoreline, and the watershed. Rising and fluctuating water levels, coupled with stronger energy waves, contribute to significant shoreline erosion. These forces can disturb lakebed sediments, which, in turn, impact aquatic organisms and their habitats. In addition, increased rainfall—often intense and unpredictable—introduces higher levels of pollutants and contaminants into the lakes, further exacerbating environmental stress. The watershed is also heavily affected by these factors, particularly in terms of increased flooding, which places additional strain on both natural ecosystems and human infrastructure. Addressing these challenges requires a multifaceted approach that combines both natural and engineered infrastructure to mitigate damage and enhance community resilience. Sinha: To add some context, climate change is causing regions around the Great Lakes to experience more rainfall in shorter periods of time, leading to severe issues such as flooding and water quality challenges such as algal bloom in western Lake Erie. The frequency and intensity of these rain events are increasing, which complicates regional water management. As an example of changed rainfall, based on 1992 estimates, a hundred-year storm in Detroit used to be 4.4 inches of rainfall, while in 2019, a similar storm produced 5.2 inches—an additional two billion gallons of water. According to SEMCOG, by 2050, storms of this nature could result in 7.7 inches of rainfall, adding another six billion gallons of water. Preparing communities and infrastructure for such occurrences is essential as we look toward the future. And these massive challenges present an incredible opportunity for the region to grow its economy by deploying capital that leads to local jobs. Q: Based on this project, what specific actions or solutions is CIS proposing to protect Great Lakes coastal communities? Vedachalam: It will take a balanced approach that integrates both hard infrastructure and nature-based solutions to address the complex challenges these coastal communities face. One focus is wetlands, which historically covered vast areas across the Great Lakes region. Over time, urbanization has led to the loss of many of these wetlands, reducing their ability to naturally manage stormwater. So, we need to design infrastructure to help slow down stormwater runoff before it reenters the lakes. Additionally, we need to stabilize dunes and other natural barriers, which play a critical role in protecting the shoreline from erosion and the impacts of fluctuating water levels. These natural elements act as a first line of defense, mitigating the force of incoming water while preserving ecosystems. Another critical area of focus is people. It’s crucial to involve residents in these efforts to ensure that the solutions we propose are compatible with how people live and interact with these spaces. Through collaborative efforts with the community, we can foster a sense of ownership and ensure that the projects we implement meet both environmental and societal needs. Q: What unique opportunities or risks does Southeast Michigan face regarding water management and coastal resilience compared to other areas of the Great Lakes? Vedachalam: Southeast Michigan presents a unique mix of challenges. Historically, this region was rich in biodiversity, with vast expanses of marshes and wetlands serving as natural buffers against flooding and erosion. However, as the area became more urbanized and industrialized, many of these natural systems were altered or lost. Despite this, there remains a kind of “ecosystem memory,” where there is potential to restore these natural practices and processes in some areas. One of the main challenges the region faces is balancing the needs of a highly industrialized and sprawling urban environment with the goal of restoring natural systems. Legacy pollution from past industrial activities continues to pose a risk. There is growing interest from communities to return to more sustainable, nature-based solutions. Q: To this end, what is the importance of polling data in understanding public sentiment on Great Lakes water issues? Vedachalam: Polling data is critical because it allows us to measure public sentiment at a specific point in time and over time. Public sentiment can be dynamic, especially following significant events, much like we see in political polling. Attitudes often shift slowly over time, so conducting annual polls helps track these changes and offers insights into how public perceptions and concerns evolve. Sinha: The Great Lakes represent a highly complex system, involving eight U.S. states and two Canadian provinces. This vast geographic area makes it essential to carefully assess how public sentiment varies across the region. Polling helps identify which stakeholders hold specific concerns and how
Scrap Soils: Innovating with a Robotic Food Waste Collection Pilot Program
Scrap Soils is a Detroit-based nonprofit composting organization, focused on diverting food waste from landfills and transforming it into nutrient-rich compost. Scrap Soils partners with entities like Sanctuary Farms to promote sustainable food waste recovery, helping businesses and residents meet zero-waste goals. Its mission is to divert food waste from landfills, thus reducing greenhouse gas emissions and creating a sustainable local food cycle through composting. In 2023, Scrap Soils piloted a robot program in the Transportation Innovation Zone with support from the city’s Office of Mobility Innovation. The program used an autonomous robot for food waste collection to explore more sustainable and efficient ways of managing and transporting waste. SBN Detroit talked to Scrap Soils co-founder Ricky Blanding about the pilot program, and composting in Detroit. Q: How did you develop the idea for Scrap Soils? What was the driving force behind it? A: I was working at the Whitney and also developing a deep interest in gardening. I began to recognize the immense value of composting in improving soil quality. At the same time, I noticed a significant issue with food waste — there was a clear gap between the waste generated and how it could be utilized productively. So the concept of Scrap Soils emerged from this realization. Composting can serve as a key tool in addressing food waste, turning it into something beneficial for the environment, businesses, and communities alike. Q: In what ways does composting help businesses and the community meet their zero-waste goals? A: Composting gives businesses a sustainable alternative for managing their food waste. Many companies are simply throwing food away because they may not have other options available to them, and what we aim to do is close that food loop. By offering businesses an opportunity to compost, we ensure that the resources they are using — and paying to dispose of — are put back into a healthier and more sustainable food system. This creates a more robust solution for food waste recovery and helps businesses and residents alike see the value in contributing to a circular economy. Q: What are some of the partnerships you’ve established with local businesses and other organizations? A: Our primary farm partner is Sanctuary Farms, and through that relationship, we’re looking at expanding partnerships with multiple farms to broaden our reach. We’re particularly focused on districts 4, 5, and 6 in Detroit. We’re also working closely with the West Village Business Association—West Village is where our home base is, and we want to be impactful in that community. Beyond that, we’ve partnered with The Schvitz, AAA, and Renaissance High School. Each of these partnerships helps us connect with different parts of the community to extend our mission of food waste recovery. We are still very new and see growth on the horizon. Q: How do you think getting businesses on board to compost contributes to Detroit’s broader sustainability efforts, particularly in terms of reducing the city’s waste footprint? A: First, composting will reduce the amount of food waste going to landfills by closing the food loop through composting. But beyond the practical aspects, there’s a larger goal of shifting the overall mindset within the community and the city. Our mission isn’t just about waste — it’s about inspiring people to care more about their environmental impact. When you get businesses and individuals thinking about closing the food loop and diverting food waste, they typically start to think about other ways in which they can address sustainability. Q: What educational initiatives are you implementing to inform the community about composting and sustainability? A: Education is key. This summer, we collaborated with Renaissance High School to run a summer cohort program, where a group of students helped us fundraise for Scraps Soils. They learned essential skills like grant writing, networking, and fundraising, as well as the broader importance of composting. It’s not just about teaching them how to compost—it’s about giving them ownership over the future of sustainability in Detroit. Q: Do you have data on the amount of food waste diverted from landfills through your composting services? A: During our pilot program, we successfully composted 11,000 pounds of food waste. While we’re still compiling numbers for 2024, we are steadily growing, and over the next 6 to 12 months, we expect to see even more progress. Currently, we have just under 50 members, but the trajectory is promising, and we’re expanding at a consistent pace. Q: How did the idea for using a robot to collect food waste come about, and what were the primary objectives of the pilot program? A: The concept of composting and mobility intersecting is interesting. Managing trucks for food waste collection is expensive and resource-heavy, so we began to wonder if there might be more efficient ways to transport food waste. Detroit is a leader in mobility innovation, so it seemed like the perfect place to test this. The pilot program has allowed us to gather data and see how technology could streamline food waste collection in the future. Q: What were the environmental benefits of replacing traditional waste collection methods with a robot in terms of reducing emissions? A: A clear benefit is the reduction in emissions by eliminating the need for traditional trucks and the people and resources required to operate them. The robot helped us centralize the movement of food waste, removing the middleman and making the process more autonomous. We’re still analyzing the full impact of the pilot program, but it’s clear that mobility innovations like this can play a role in creating a more sustainable system. Q: How do you see technology shaping the future of waste management and composting in Southeast Michigan? A: We’re constantly learning about the evolving nature of mobility and how it connects to waste management. Looking ahead, I envision diversifying the types of vehicles we use and where the food waste ultimately goes. The city has been very engaged in observing the impact of our program, and we’ve gained valuable insights into
The Growing Role of Refill Shops
The concept of refilling containers to reduce plastic waste and promote sustainability is taking hold in many forms. From pop-ups to brick-and-mortar, Refill Shops, known as refilleries, are becoming more prevalent. To find out more about the industry, SBN Detroit interviewed three local business owners: Corey Thompson, founder of Red Oak Refillery with installations in two locations; Jessica Cichowlas, owner of BYOC with brick-and-mortar locations in Ann Arbor and Plymouth, and Ashby Cummings, owner of MI-Fillosophy in Plymouth. Q: Why a refillery? Thompson: The inspiration for Red Oak Refillery came from my time working at Mama Suds, a brand focused on natural household cleaners. By 2021, we were seeing that roughly 30% of Mama Suds’ wholesale sales were directed to refilleries, predominantly on the East and West coasts. This made it clear that there was a need for refill services in other areas as well. I started my business as a pop-up in Oxford in 2021, working part-time with my product set up at a coffee shop in Lake Orion. Setting up my products for a few hours each day gave me the opportunity to fine-tune my model. Instead of going the traditional brick-and-mortar route, I opted for a distributed model with installations in businesses that align with my values. I currently operate in two locations and am preparing to open a third, all while continuing my role at Mama Suds. Cichowlas: I was a customer at BYOC, and the mission of reducing single-use plastic resonated deeply with me. The owner announced she was selling and I took over the two locations – Plymouth and Ann Arbor. My goal remains to uphold that mission, with a focus on sourcing from local family-run businesses that reflect our core values of sustainability and environmental responsibility. Cummings: Mi-Fillosophy launched in February 2023 with a focus on food rather than lifestyle products, which sets us apart from most refill shops. I noticed a significant gap in the market, particularly after many bulk food stores shut down during the pandemic, and I wanted to address that gap by offering consumers a more sustainable way to shop for food. Q: How has the community responded to the concepts of container reuse and the reduction of single-use plastics? Thompson: The community response has been positive. For some, the idea of a refillery is novel and intriguing, though it’s a concept that has been common in places like India for centuries. Others have embraced the concept and seek out refill shops that align with their sustainability goals. Beyond that, the community also has actively sought me out for collaboration. For instance, Orion Oaks Elementary reached out for assistance in achieving certification through the Green Schools Program, and I got invited to speak at various summits and conferences. I think refilleries naturally become hubs for education and sustainable practices within their communities. Cichowlas: The Ann Arbor community has embraced the refill shop a bit faster, I think, because the city has committed to sustainability goals – aiming for carbon neutrality by 2030. So, our store’s mission really resonates there. We’ve seen growing support in Plymouth as well, as more people begin adopting zero-waste practices. Cummings: Customers have responded positively to a refill shop focused on food. Many like the option of purchasing smaller amounts or just what they need, which helps them avoid unnecessary waste. Q: How has your clientele evolved over time? Thompson: Our customer base continues to consist of both repeat visitors and newcomers. Some people actively seek out refill shops as part of their efforts to live more sustainably, while others are discovering the concept for the first time. It’s rewarding to see that growth and interest. Cichowlas: We’ve developed a strong core of repeat customers, most of whom are local. However, we also see people traveling from further distances to stock up on refills, which is a testament I think to more people adopting sustainability practices. Cummings: I’ve drawn customers from all around metro Detroit, but more and more refill shops are opening so people don’t have to drive as far to reach them, which helps from an emissions reduction standpoint and therefore is great. Many people from the local community here have become regulars. Q: What challenges have you faced in operating a refill shop? Thompson: One of the biggest challenges is that this industry is still relatively new, so we’re dealing with the typical obstacles any startup faces. Beyond that, educating the public about the refill concept is a continuous effort. Cichowlas: Our main challenge is keeping our costs competitive with larger chains while maintaining our commitment to sustainability and local sourcing. Cummings: For me, since my focus is food, managing food safety is a challenge. Keeping track of expiration dates and managing recalls. There’s also a need for constant education, particularly around bulk food safety, which some customers are unfamiliar with. Q: What role do refill shops play in educating the community on sustainability? Thompson: Refill shops play a critical role in community education, whether we intended it or not. Customers come to us with questions, and we find ourselves being the ones to provide answers. It’s an organic process — people look to us for guidance. I also think the local refill shops act as an example and a reminder to think more sustainably. Cichowlas: I believe refill shops have an obligation to educate the community. From understanding which ingredients are safe to selecting products that align with sustainable values, we can remove a lot of the guesswork for people and it’s a service that’s important. Zero-waste can seem intimidating, so part of our mission is to make it accessible and achievable for everyone. Cummings: The presence of a refill shop brings sustainability to the forefront of community awareness. Every day, whether it’s answering questions about recycling or helping customers choose eco-friendly products, we’re educating our customers. Q: How do refill shops help reduce the carbon footprint? Thompson: The impact is significant, even with small changes. Just using a container
