Cities unearthing best practices for compostable plastic – USAPosted on September 16, 2013 by DrRossH in Plastic Waste News
Compostable plastics are making the job easier but there are challenges to overcome from manufacturers “greenwashing” products labels to composters determining what will breakdown in an appropriate time frame given the temperature and moisture of their facility.
Biodegradable doesn’t equate to compostable. Biodegradable is a vague term without a time frame. A tree is biodegradable but it can take centuries while composting is a managed process with definitive temperatures and times to create humus.
