In research sponsored by the Mattress Recycling Council, Edge Global Innovation has developed a process to transform polyurethane mattress foam into polymer pellets that can be used to produce a wide variety of molded products, including shoe soles, cellphone cases or rubber gaskets for various industrial uses.
According to a news release, Clearwater, Florida-based EGI used earlier MRC research to develop a process and machinery to reduce the volume of the foam by 90 percent. The process does not use catalysts or solvents, which minimizes the environmental impacts of the technology. The end product is a thin, flexible sheet of synthetic rubber.
This material is then ground and mixed with additives to create reformable pellets. The additives, including coloring, can be tailored to make a specific mixture needed for molding into new products like shoe soles. The research determined that the pellets could be composed of up to 75% recycled mattress foam. The balance would be virgin polymers and other additives. In addition to recycled mattress foam, the process can use post-industrial scrap foam obtained directly from foam manufacturers, the news release said.
“This is an exciting new development that can open the door for making many high-value products from recycled polyurethane foam,” said Mike O’Donnell, CEO of MRC. “We look forward to seeing commercial adoption of this technology to improve the circularity of mattress foam.”
EGI has formed a subsidiary, Vitricycle, to manufacture and market the pellets, which has patents pending in the U.S., the European Union and China.
“We see tremendous potential,” said Vahid Serajian, CEO at Vitricycle. “By converting bulky, hard-to-recycle mattress foam into versatile pellets, we’re not only addressing a major environmental challenge but also creating new opportunities for sustainable manufacturing across industries. Our goal is to lead the way in transforming waste into valuable resources and contribute to a more circular economy.”
Company officials said with the low environmental impact of the conversion process, Vitricycle could also empower mattress recyclers to process foam on-site. Using the company’s proprietary machinery and know-how, the recycler could create a high-value product to sell into new secondary markets.

With the completion of the successful commercial pilot test, Vitricycle is now seeking full commercialization of the technology by offering to license its intellectual property, sell or lease its machinery and develop markets for the pellets. It is also seeking investors to assist in developing the technology and new markets.
