Current knowledge on microplastics, while growing, is still early with much to be understood. This leaves our approach to designing a competition that promotes conventional plastic alternatives in a dark place; in order to mitigate the potentially destructive characteristics of alternative materials, we need to test for microplastics and ultimately understand how things break down within a reasonable timeline for a competition.
Considering existing bio-based materials, what would be the best-in-class timeframe for complete biodegradation (aka, complete mineralization: water and gas) ? We are particularly interested in hearing more about the following environments:
Surface of the Sea
Soil – surface
Soil – lightly buried
Can you recommend relevant standards/guidelines for testing?
