Title: Timothy Glenn Schaefer and Chemical Recycling Innovation.
Introduction
Timothy Glenn Schaefer is an inventor based in Kingsport, Tennessee, and is associated with Eastman Chemical Company. His work includes patent inventions focused on chemical recycling processes for plastic waste. He is credited with 3 patents.
Latest Patents
Schaefer’s recent patent work addresses the recovery and reuse of chemical components from coproduct streams generated during plastic recycling.
“Chemical recycling of solvolysis terephthalyl column bottoms coproduct streams” describes methods for processing waste plastic by directing at least part of a terephthalyl column-bottoms coproduct stream from a PET solvolysis facility to a partial oxidation gasification facility, pyrolysis facility, cracker facility, or energy-generation facility. The patent also concerns coproduct compositions formed during the solvolysis of polyester terephthalate-containing waste plastic.
“Chemical recycling of solvolysis glycol column bottoms coproduct streams” describes chemical recycling facilities designed to process mixed plastic waste. The facilities can combine solvolysis, pyrolysis, cracking, partial oxidation gasification, energy generation, and solidification. By using streams from one facility as feed for another, the approach aims to recover valuable chemical components and reduce unusable waste.
Career Highlights
Schaefer’s listed inventions focus on integrating multiple processing technologies to improve the handling of plastic waste and recycling coproducts. His work reflects an approach in which outputs from one process can serve as inputs to another, supporting material recovery across a connected facility.
Collaborations
Schaefer is associated with Eastman Chemical Company. His listed coworkers include inventors Travis Wynn Keever and Aaron Nathaniel Edens.
Conclusion
Timothy Glenn Schaefer’s patent work centers on chemical recycling systems that connect processing facilities to recover useful materials from plastic waste and coproduct streams.
