Eastman will gasify plastic waste

by Alexander H. Tullo
April 5, 2019 | APPEARED IN VOLUME 97, ISSUE 14

The process, which the firm calls carbon renewal technology, will substitute plastics for some of the coal that it gasifies at its complex in Kingsport, Tennessee. Eastman uses the resulting synthesis gas—a mixture of hydrogen and carbon monoxide—to make acetic acid and acetic anhydride as raw materials for cellulosics. Last month, Eastman said it is commercializing a technology to recycle polyethylene terephthalate into its raw materials.
