"First, lactic acid is fed into a reactor and converted into a type of pre-plastic under high temperature and in a vacuum,
The pre-plastic-a low-quality plastic-is broken then down into building blocks for PLA. n other words,
you are first producing an inferior plastic before you end up with a high-quality plastic. And even though PLA is considered a green plastic,
the various intermediary steps in the production process still require metals and produce waste.""The KU Leuven researchers developed a new technique by applying a petrochemical concept to biomass."
