There are initiatives across the Globe to advance the circular economy including reports and funding from the European Commission, China’s eco-parks and within US funding opportunities from agencies like NSF, DOE; and foundations, such as the Ellen G. MacArthur Foundation, and other organizations (ThinkBeyondPlastics, Ubuntoo) that support  replacement of plastics with sustainable alternatives. For example, the MacArthur Foundation supports the New Plastics Economy accelerator (https://www.newplasticseconomy.org/) which has engaged over 1000 companies and organizations as signatories to a Global Commitment to circular plastics.
RBI’s “Circular Materials” focuses on polymer-based materials, including composites, with the ultimate goal of identifying materials and/or processes that can minimize the use of non-sustainable resources (fossil fuels) as feedstocks or energy sources. That includes:

• Recycling at the molecular level, for example molecular restoration or regeneration, which is very common in nature, through such processes as mechano-catalysis, separations, electro-catalysis, etc.; 
• Replacing the functionality provided by petroleum-based polymers with polymers from biomass. Optimized biomass processing to synthesize common monomeric building blocks and/or new ones through approaches as redesign of products, processes, policies, economies and workforce education. 
• Reducing the energy input and other resources i.e., water, materials and transportation costs, minimizing waste streams e.t.c., in current manufacturing processes of products made using petroleum-based feedstocks.
