Degradation of different plastic materials (IMAGE)
Caption
Experiments on the degradation of different plastic materials. Top left is a common LDPE plastic film. Top center and right are the researchers' amylose-based bioplastic and a plastic made from corn starch, respectively. At the bottom are three different bags made from conventional bioplastics. A) shows the start of the experiment. B) shows the degradation after 8 days, C) the degradation after 11 days, D) 21 days E 41 days and F) shows the degradation after 54 days. Photo: Andreas Blennow
