Comment on Life cycle assessment of enzymatic PET recyclingparent

Comments

Because it is an enzyme, it will have a relatively high specificity of action (it will not act on a different target) and as it decomposes the stuff in a nice clean molecule[0], this should work. Except of course if you pour in the mix something neutralizing the enzyme.

At the end, you always need to separate, the process engineers will have to figure out what is the best method (washing, crystallization, distillation or direct reaction to build longer polymer chains, ...).
