KHOI Interview with CB2 Center Director

 

The show started with the roundup of Ames news from Dennis Hart. Then today's host, Gale Seiler, interviewed Dr. David Grewell from the Department of Agricultural & Biosystems Engineering at ISU (13:00), where he is also Director of the Center for Bioplastics and Biocomposites (CB2 ). They spoke about the problems caused by plastics in the environment and efforts to use plant proteins to make biorenewable, biodegradable plastics.

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.
