Post-Consumer Cullet In California

Source separation of waste streams and toxic content restrictions are crucial actions toward optimizing the value of recycled feedstocks in building products. HBN’s research on glass waste – known as cullet – reveals the multitude of economic and environmental benefits of these practices. The ability of fiber glass insulation manufacturers to incorporate cullet increases; the wasteful landfilling of discarded glass (nationally, only 28% is recycled) decreases. Manufacturers need less energy to produce insulation, leading to lower greenhouse gas emissions. Workers, surrounding neighborhoods, and the environment at large are exposed to fewer toxic contaminants. Post-Consumer Cullet in California is the second in a series of Healthy Building Network reports for the Optimizing Recycling collaboration.
