Post-Consumer Flexible Polyurethane Foam Scrap Used In Building Products
Healthy Building Network’s research into current recycling practices for flexible polyurethane foam (FPF) indicates that most post-consumer feedstocks are contaminated with highly toxic flame retardants. Discussions of recycling FPF have centered around the human health and environmental hazards posed by the flame retardant PentaBDE, which the foam industry phased out a decade ago. But the flame retardants that have replaced PentaBDE present similar concerns. Manufacturers incorporate flame retardant-laden post-consumer FPF into new products, primarily bonded carpet cushion. Recycling and installation workers and building occupants, particularly crawling children, can be exposed to these toxic chemicals. The recent emergence of pre-consumer FPF scrap that is free of flame retardants is a great step toward a safer, more valuable feedstock, but more work is needed to track and label flame retardant-free FPF to ensure that future post-consumer foam is also flame retardant-free.
