Biodegradation of Bioplastic Plant Containers in Home Compost at Two Weeks

This video shows results during the first two weeks of biodegradation with over twenty types of bioplastic composites in a home composting system. This is the first in a short series of videos that will illustrate the biodegradability of these biorenewable polymers and composites in home compost. This research is part of a five-year bioplastic container cropping systems project led by CB2 faculty.
