Abstract

High concentrations of recycle polymer are gasified in a partial oxidation gasifier to make a syngas useful to make a variety of chemicals and polymers, such as cellulose ester. Polymers such as cellulose esters can be made that are obtained from sustainable sources, recycle sources, and are biodegradable. Circularity in the manufacture of textiles and/or plastics made from the fibers of such cellulose esters can now be achieved. The process of making such a syngas from high concentrations of recycle polymer (e.g. textiles and/or plastics) includes campaigning for the production of syngas.
