Protecting the World’s Largest Geyser Ecosystem with Recycled Tires

October 17, 2017

Among the uses for recycled tires is pavement. Today’s NERC Blog article by Lauren Davis, Public Relations Coordinator at Michelin, talks about a recent project using recycled tires at Yellowstone National Park.


Yellowstone National Park has completed the second phase of its initiative to install more eco-friendly walkways in the world’s largest concentration of geysers and thermal features. With help from the Michelin Corporate Foundation, Yellowstone National Park has so far paved 11,100 square feet of pathway with the recycled material, replacing crumbling asphalt paths.


The new walkways are made from an innovative eco-friendly paving material that is manufactured in part from recycled tires. This new material will help reduce run-off and erosion in the eco-sensitive Yellowstone Geyser Basin, which features the iconic Old Faithful geyser and attracts millions of visitors a year.


The recycled tire pavement is called KBI Flexi®-Pave. This product provides a porous, durable and flexible surface that allows the water from rain and snow to percolate through the walkway the way it would have done before the walkways were installed. This in turn creates more natural water patterns that eventually replenish the geyser basin. Unlike asphalt, this paving material does not create significant storm-water runoff or leach pollutants into the soil. It also does not break apart, which prevents material from ending up in geysers and hot springs.


Some 2,400 tires were donated for the project, with this second phase using 1,536 end-of-life tires to help create thousands of square feet of paths. Most of these tires were originally donated several years ago by Michelin for use on Yellowstone’s more than 800 fleet vehicles and commercial equipment. A total of $1.5 million in donations and in-kind have been used thus far for the project. Around 1,500 volunteer hours have been logged on the pathway project.


Flexi-Pave not only provides an environmentally friendly solution for the Old Faithful area, it prevents thousands of old tires from ending up in a landfill or being burned for fuel. The project was made possible through a partnership between Yellowstone National Park, park concessioners, the Yellowstone Park Foundation, KBI Industries and the Michelin Corporate Foundation.


“The Yellowstone Walkways Project aligns with Michelin’s commitment to being a global leader in sustainable mobility,” said Leesa Owens, director of community relations for Michelin North America. “Our employees have been involved with this project from the start, working directly to help create environmentally friendly walkways out of Michelin tires that had already provided Yellowstone with years of cost-effective and fuel-efficient operations.”


Flexi-Pave is made of rubber granules and stone held together by a polymer binding agent that is inert when cured. Its open-pore design enables fast evacuation of up to 4,000 cubic inches of water per hour. Beyond Yellowstone, this innovative product has a broad range of applications. The thousands of rubber granules making up its surface make it non-slip and it is an ADA-compliant surface accessible to wheelchairs and walkers. The integrity of the materials are not affected by freeze-thaw conditions which is why it works well in cold and snowy parts of the Northeastern and Midwestern United States.


 “Yellowstone is the world's first national park with nearly 150 years of balancing the protection of natural wonders and sharing them with visitors,” said Lynn Chan, a landscape architect for the National Park Service and lead on sustainability at Yellowstone National Park. “It is important to us to rehabilitate the park’s walkways with materials that can help protect this sensitive environment yet still allow visitors to see and appreciate it.”


“This project represents the model for collaboration between public and private organizations. We hope that this eco-friendly park walkway will inspire other similar projects that help preserve natural systems,” said Jeff Augustin, vice president of external partnerships at Yellowstone Park Foundation.

New program prepares the next generation of recycling professionals

By Recycling Product News • October 14, 2026
The Recycled Materials Association (ReMA) and the Northeast Recycling Council (NERC) have launched a new pilot initiative to train the next generation of recycling professionals: the Sustainable Materials Careers Program (SMCP). Take a look inside the Sustainable Materials Careers Program Building on the success of NERC's Emerging Professionals Program, which offers new professionals exposure to sustainable materials management (SMM), mentorship, and career guidance, SMCP will focus on college students — with the potential to engage high school students in the future. The program will give students a deeper understanding of career opportunities in SMM and provide hands-on pathways from the classroom to the workplace. Through Career Exploration events and professional development training, students will gain industry exposure, build foundational knowledge, and chart a clear path toward careers in sustainable materials. Career Exploration events will be part of ReMA's Recycling Jobs Day initiative, a national program connecting students with careers in the recycled materials industry. Event activities will include tours of material recovery, recycling, and/or manufacturing facilities, as well as panels highlighting diverse career pathways in the sector. "Many students want to work in sustainability, but they rarely see the diverse career paths available across the materials lifecycle," said Megan Schulz-Fontes, executive director of NERC. "By combining hands-on facility tours with foundational training, this program opens doors across every corner of the industry — including state and municipal governance, equipment and technology manufacturers, recycling infrastructure, and corporate sustainability teams — ensuring the next generation is equipped to lead." Growth in sustainability has increased the number of professionals needed to run the industry The material economy accounts for over 40 percent of U.S. greenhouse gas emissions, according to the EPA. Recycling and composting in the United States prevent the release of roughly 186 million metric tons of carbon dioxide equivalent into the air each year — an impact equal to taking over 39 million gasoline-powered cars off the road annually. Compared to the processing and transportation needed for mining, drilling, harvesting, or other methods of extracting natural resources for manufacturing, the use of recycled materials typically produces fewer greenhouse gas emissions. Global demand for green jobs is growing at 8 percent per year. Yet, LinkedIn's Global Green Skills Report highlights a shortage of qualified talent, with many roles unfilled due to limited training and a lack of mixed skills, as noted by the Institute of Sustainability Studies. SMCP addresses these gaps by increasing awareness of sustainable materials careers and offering free training to participating students. In the 2026-2027 academic year, NERC plans to hold six Career Exploration events and provide enrollment in its Foundations of Sustainable Materials and Recycling course at no cost to students from participating Academic Partners. Current Academic Partners include MIT Department of Materials Science & Engineering, Rowan University Advanced Materials & Manufacturing Institute, University of Massachusetts Lowell, University of New Hampshire Sustainability Institute, University of Southern Maine, and Yale.

Ramping up reuse of construction materials

By Brian Clark Howard | Resource Recycling • October 8, 2026
The construction and demolition industries send a massive volume of materials to landfills, but reuse can make a big difference, panelists said at the Northeast Recycling Council’s (NERC) Annual Rethink Resource Use Conference in Plainsboro, New Jersey on Wednesday. In New York City, 60% of the total waste stream is construction and demolition (C&D) waste, said Kelly Tigera, the founder and CEO of Orbit , an online marketplace for reclaimed construction materials launched in 2005 in the Big Apple. In the US overall, C&D waste has been estimated at 23% of the total waste stream . According to the EPA , 600 million tons of C&D debris were generated in the United States in 2018, which was more than twice the amount of generated municipal solid waste. Just over 455 million tons of C&D debris were directed to next use (primarily as aggregate); the rest went to landfills. Construction is “one of the most wasteful industries,” said panelist Andrew Sigal, a market manager at the U.S. Green Building Council (USGBC). “Within that 145 million tons lies a significant opportunity to really decrease waste and direct more material towards its highest and best use.” At New York construction sites, 10% to 15% of all new materials are thrown away unused, said Tigera. So reuse has the potential to draw from brand new stock as well as used materials. And reuse can help address supply chain and affordability concerns; construction material costs have increased 43% since February 2020, said Tigera. “In terms of value for users, we can provide access to free and low-cost materials,” said Tigera. “We can provide tax write-offs for donated materials, and we also help sellers save on hauling and dumping costs.” From panels to seats Tigera gave a few examples of recent salvage efforts that have leveraged her marketplace. Deconstruction contractor CO Adaptive recovered wood panels from an auditorium at Hunter Brookdale School of Nursing. The panels ended up in four different sites around Brooklyn. Auditorium seats were donated to SoHo Playhouse. In another project, Orbit worked with the city’s Port Authority to salvage historic bricks from retaining walls in Lincoln Tunnel. Orbit is also working with the agency to design a reuse plan for a bus terminal that is scheduled to come down in a few years. New York City also has a new initiative called the Circular Construction Hub, which is going to be a reuse center for contractors where they can drop off material. Orbit is the online marketplace for that project, said Tigera. She added that some of the most popular materials on her platform have been doors, shelving, cabinets and acoustic panels. In addition to traditional contractors, buyers include the film industry (for building sets) and the events industry. A lot of reuse work is already happening around the city and country, “we’re just helping it scale,” said Tigera. Yarden Jarari, an architect and sustainability adviser at Arcadis , a design and engineering firm, said her recent research suggests the value of pilot projects when it comes to reuse in the C&D space. “You can have pilot projects that are not going to totally overwhelm someone trying something new,” she said. “And also iterate over time with a lot of long-term relationships where you have repeat partners, repeat teams, and have that opportunity to build and bite off more and more rather than trying to do everything at once.” Jarari added that she would like to see “ways that we can start to measure outbound materials that are coming out of a space the same way that we’re thinking about what’s going into a space.” Having that data could make it easier to drive reuse, she said. Sigal said certification systems, like those offered from the USGBC, can incentivize reuse. The organization’s True certification for zero waste (with Green Business Certification Inc.) has a particular focus on reuse, he noted. As a case study, Sigal mentioned 270 Park Ave. in midtown Manhattan. The 60-story headquarters of JPMorganChase opened in October 2025 as a LEED platinum project. The previous building at the site, the former headquarters for Union Carbide, was deconstructed, with 97% of its materials reused or recycled. Evolving mindset The panelists agreed that the mindset in the C&D industry is starting to tilt toward reuse, spurred by environmental and cost concerns. “Our thesis has been if we can provide demand and show that there’s demand for these materials, everything else will wind up behind it,” said Tigera. She added that government procurement can help drive more reuse in the industry. Tigera also pointed out that salvaged materials are often routed through resellers, who clean and organize them, making purchasing of used goods as easy as buying new. Sigal added that he would like to see more policy support for C&D reuse. In New York, several bills have been introduced that would bolster reporting and encourage reuse. “Building reuse saves carbon, but also saves resources from having to be extracted, harvested, manufactured and installed,” said Sigal. “Not to mention the end-of-life considerations there.” Read on Resource Recycling.
