What are the Problems with C&D Recycling? C&D recycling has a wide range of benefits and the EPA reports that of the 600 million tons of C&D waste produced, approximately 455 million tons are effectively recycled and 145 million tons are sent to landfill. Whilst this a significantly larger proportion than many other waste streams, it still …
