Working to Sequester Carbon Within Urban Wood
According to Tiffany Giacobazzi, Ann Arbor urban forestry & natural resources planning coordinator the Ann Arbor Forestry Department, the city of Ann Arbor loses about 600 trees per year. This reduces its carbon storage capacity dramatically. Much of the loss sits within furniture-grade urban lumber, meaning the trees can be repurposed for furniture or other long-lived urban wood goods that aid in sequestering carbon, versus being used for mulch or firewood or being diverted to landfills. Ann Arbor has partnered with Urban Ashes to implement its Circular UrbanWood Triconomy™ (CUT Model™). This model is meant to ensure that logs are put to their highest and best use to sequester as much carbon as possible. SBN Detroit spoke with Paul Hickman, Urban Ashes founder, CEO, and principal designer, and Tiffany Giacobazzi, Ann Arbor urban forestry & natural resources planning coordinator, to find out more. Q: What is Urban Ashes, and how did this program with Ann Arbor come to be? Hickman: I will provide a little background here for context because Urban Ashes has gone through a bit of an evolution. Initially, it started with a major career change for me by taking a job in California with one of the first sustainable lumber companies in the world. I eventually moved back to Michigan and started the original Urban Wood Project with three others in the early 2000s in response to the infestation of the emerald ash borer to help utilize trees beyond mulch, which was the most common response for the disposal of ash trees then and now. That was the impetus, but it immediately expanded to include all fallen urban trees and into Urban Ashes. Urban Ashes grew to sell to over 250 retail partners across 43 states over ten years, repurposing hundreds of tons of lumber into picture frames, furniture, and other items. From the beginning, our focus was also to work with formerly incarcerated individuals as a labor force, and that remains a strong component of the Urban Ashes business model today. Over time, the lack of wraparound (support) services (for workers) took a heavy toll, and eventually, we shifted entirely, shut down our manufacturing, and decided we needed to focus on building the infrastructure to develop the supply chain more thoroughly and consistently and grow the markets for utilization as well as develop the critically needed wraparound services needed for our target labor pool. So, we partnered with NextCycle Michigan and went through their FLOWS track which led to an EGLE grant. Then came the vision for the Circular UrbanWood Triconomy™. We were fortunate enough to work with the University of Michigan graduate students for 18 months to validate the viability of the model, and beginning in 2021, we have piloted it with the city of Ann Arbor. Q: How and why did the city of Ann Arbor come to change the way it processes trees and work with Urban Ashes? Giacobazzi: As the city has shifted with its sustainability goals and A2Zero plan, we started to look at how we could divert more out of the waste stream. We wanted to achieve the highest best use for materials that come out of the urban forest. So, we connected with Urban Ashes and partnered on this project. I have support all up and down the line from city administration which is really important. We are fundamentally changing the way we are dealing with urban wood and our urban forest so we must all be in support of this new process. Q: What does this program involve? Hickman: For years, all fallen urban trees in Ann Arbor (as is the case with most cities) were used for mulch or firewood. Accordingly, Ann Arbor loses approximately 1,111 metric tons of carbon every year and we were able to show them that by implementing the CUT Model™, we can capture upwards of 700 metric tons of that 1,111 and keep it in use and sequestered. The process involves cutting the trees down in a way that holds the most carbon and is best suited for the mills. The process also involves setting up the mills, facilities, contracts, and tracking methods, and then implementing everything. So, that is the work that Urban Ashes has been doing. Q: What do you, as the Urban Forestry and Natural Resources Planner, hope to achieve through Circular UrbanWood Triconomy™? Giacobazzi: I want to make sure the trees and lumber that have to come out in Ann Arbor go to the best use possible. I want it diverted from the waste stream and we are looking to lock up the carbon for as long as possible. We put such time and effort and thought into the development, care, and maintenance of our urban forest, it seems that the next natural best step is to complete the lifecycle of these trees and extend the usefulness of the trees once they die or have to come out. Q: In what ways has the lumber from Ann Arbor been repurposed? Hickman: Typically, the lumber goes to mills to be cut into slabs or dimensional lumber, kiln-dried, and processed, and then is sold as raw lumber to manufacturing or local woodworkers. The wood is then used for items such as furniture, frames, ceiling/wall cladding, flooring, household trim packages, decorative pieces, and more. Q: What other cities are you working with? Hickman: We are farthest along with Ann Arbor. But we are also working with Grand Rapids and are in talks with Detroit, Lansing, Traverse City, and several others outside of Michigan. In terms of businesses, we are working with a startup through Centrepolis called Lily Pad Labs out of Holland, Mich., to provide urban black locust for decking and tables for their autonomous electric boats. We are also working in conjunction with Centrepolis to help bring Daika Wood’s game-changing urban wood waste processes and products to Michigan. These are a few of the things we have happening at the moment. Q; In what ways do you think Urban
Creating a Closed-Loop Supply Chain for Recycling in Michigan
The Department of Environment, Great Lakes and Energy (EGLE) is working to grow a Michigan circular economy through recycling. Matt Flechter, recycling market development specialist at EGLE, says recycling programs in Michigan involve building a strong supply chain so the valuable commodities that businesses need make their way from the curb to new products. SBN Detroit spoke to Flechter to find out more. Q: Tell me about your role when it comes to recycling. A: For the past 22 years, I’ve been working toward the goal of helping Michigan regain a leadership position in recycling. I work for the Department of Environment, Great Lakes and Energy (EGLE), and my role is focused on recycling market development. This essentially means making sure there is a process in place for the materials that are put into dumpsters by manufacturers and businesses to make their way into sorted waste materials and then into reproduction, ultimately to make new products that are developed in Michigan. This sounds straightforward in its most basic terms, but recycling is a complex system. It takes motivated individuals to know that there is a better use for the materials that are being disposed of. It takes investing in the collection and hauling of materials. It takes reproduction and remanufacturing, and it takes having a market: end users that then purchase and/or use those materials. The last piece of this complex puzzle is ensuring that there are entities in place for each part of the cycle – and that they are connected – creating a fully functional closed-loop supply chain. Q: What are the biggest challenges? A: Recycling markets are diverse. Materials consist of plastic, paper, organics, and glass, and each has its own supply chain. Some have ready-made markets. Corrugated cardboard is an example here, as it can be bailed and sent to paper manufacturers for reuse. Finding markets to create a demand pull for a material like glass is more challenging. Another challenge is the geographic location of the manufacturers involved in the reproduction because transportation of materials can get costly. Also, many of these end markets are startups, and they need support and innovation, and new uses to create demand-pull. Good examples of these are Pivot Materials and NexTiles. For all of this to work, and for manufacturers and businesses to move from the use of non-recycled materials to recycled materials, there must be a consistent supply of these materials. So, the supply chains we are building need to be closed-loop, local, and robust. Q: How do EGLE and NextCycle Help? A: To address each part of the cycle I described, EGLE created NextCycle, and we collaborate with partners such as Centrepolis, Michigan Recycling Coalition, and Resource Recycling Systems, a global consultancy. We have made amazing strides in the last couple of years – with momentum coming from our NextCycle initiative. NextCycle is an incubator and accelerator and is designed to connect entrepreneurs, companies, organizations, and communities to technical support, financial resources, and capacity building for recycling, recovery, and reuse initiatives. If someone comes to us with a new idea, that company first applies to one of the NextCycle challenge tracks. There are five challenge tracks: Roads, Public Sector, Recycling Supply Chain Solutions, Organics Solutions, New Innovations, and Technology. They are then selected into a cohort or a team and we provide several areas of support, including technical assistance, research data, business development, funding opportunities, an extensive network, customized mentorship, and more to help get the idea to the next level. We have worked with over 60 teams, and it’s an exciting time when it comes to recycling. Q: How so? A: We are seeing a resurgence and interest in making sure Michigan has a strong circular economy, primarily because there are new people at the table focused on climate goals and deciding how they are going to tell their businesses’ sustainability story. Historically waste and recycling have been seen as an afterthought – we have a problem and now need to fix it. Businesses today are starting to look at fixing the problem before it’s created, which is a big paradigm shift that’s exciting. There is a lot of growth in this sector and there are threads of it in every business in Southeast Michigan. Every business is faced with choices and options to address the triple bottom line. This is also creating new business opportunities. There are broader-based coalitions working to expand recycling access, such as the Polypropylene Coalition and the Food Service Packaging Institute. There are also new people looking to fund. No longer is it just the government growing the recycling system. This increased participation and the growth of the end markets are exactly what is needed for success. Q: What Southeast Michigan businesses are you working with? A: I can give a few examples here. On the collection side, Pink Elephant Events provides zero-waste event services and waste diversion to the events industry, businesses, and nonprofits in Southeastern Michigan. They collect products for reuse, then calculate the impact, so that the business having the event can show a tangible “win’ toward their sustainability goals. An example on the processing side is Glacier. This California-based company identified Michigan as the best place to invest in deploying its innovative robotics technology. We connected them to two materials recycling facilities (MRF)s in Michigan to do so – SOCRRA in Troy and RRRASOC in Southfield – and provided grant funding. An example of end-use is Industrial Sewing and Innovation Center (ISAIC). We helped them to secure funding for equipment to more efficiently turn waste textiles into new products. We are starting to see a truly circular economy forming. The new businesses are feeding off of each other and multiplying. Q: Where does your passion come from? A: There is a huge amount of work to be done in recycling, but it’s a labor of love. I can see the growth potential now. There is funding to grow markets and that has created a clear process and
