About 1,300 tons of cotton fibers and coir (coconut fiber) are extracted from discarded mattresses annually, according to Mattress Recycling Council’s 2021 mattress composition study. Most of these materials are landfilled due to a lack of secondary markets. In 2022-23, MRC launched a study to understand if cotton and coir (combined together) could be composted in commercial composting facilities in California. GreenWaste Z-Best Composting Facility in Gilroy, Calif., concluded, through standardized processing and testing, that composting could be a viable solution for mattress recyclers seeking to divert this material from California landfills.
