The purpose of this report is to analyze developments in bio-based mono-ethylene glycol (MEG) technologies. Renewable MEG is a drop-in chemical that has received some attention in recent years as the major fraction of global production of MEG goes into PET, which is used to produce polyester fibers and beverage bottles. The purpose of this study is to assess the technical, commercial, and economic aspects of producing ethylene glycol from renewable feedstocks.
