U.S. Department of Energy's BOTTLE Consortium

Lending its materials science expertise and state-of-the-art facilities, NREL's advanced manufacturing researchers provide prototyping and mechanical characterization of advanced composites used in the redesign of recyclable materials.

The Bio-Optimized Technologies to keep Thermoplastics out of Landfills and the Environment (BOTTLE™) consortium is developing new chemical upcycling strategies for today's plastics and redesigning tomorrow's plastics to be recyclable-by-design.

BOTTLE conducts high-impact research and development to deliver scalable technologies that enable cost-effective recycling, upcycling, and increased energy efficiency for plastics.

Under the BOTTLE research framework, the consortium is working to deconstruct waste plastics with catalysis and use chemical and biological transformations to upcycle the resulting intermediates to produce recyclable by design polymers.

Under the BOTTLE research framework, the consortium will work to deconstruct waste plastics with catalysis and use chemical and biological transformations to upcycle the resulting intermediates to produce recyclable by design polymers. BOTTLE will also and augment new recyclable materials with bio-based and waste-based inputs. Graphic by Elizabeth Stone, NREL

BOTTLE is a multi-organization research consortium led by the U.S. Department of Energy's Advanced Manufacturing Office and Bioenergy Technologies Office. BOTTLE is part of the Plastics Innovation Challenge, designed to accelerate innovations in energy-efficient plastics recycling technologies by 2030. Learn more about the BOTTLE consortium.

Partners

This collective effort includes national labs and academic universities. Led by NREL, the research consortium also comprises experts from Los Alamos National Laboratory, Oak Ridge National Laboratory, Colorado State University, Massachusetts Institute of Technology, Montana State University, and Northwestern University. BOTTLE will also closely collaborate with the Centre for Enzyme Innovation at the University of Portsmouth in the U.K.
