I am mystified by this article. So, it's about digesting plastic using some enzyme(s) as (a) catalyst(s). Fine. 1. But what is the end product? Digested to produce what? One would hope it does not include carbon dioxide or methane. Plastics in landfills produce neither (unless, of course, the landfill catches fire). 2. Where and/or what is/are the proposed application(s)? (I suppose if this article were in a chemist-specialist newsletter these queries wouldn't be required, but it is not.)
