Scientists unveil bioplastic that degrades at room temperature, and outperforms petroplastics

How clever of them! Using cellulose so it degrades easily at room temperature is a good answer. 

WashU's chemical engineers decided to introduce cellulose nanofibers to the design of bioplastics.

"We created this multilayer structure where cellulose is in the middle and the bioplastics are on two sides,"

And thus you have something that may help with some of our plastic problems.
