摘要： Described herein is a chemical process for the conversion of lignocellulosic biomass into muconic acid which is useful for the generation of plastics and polymers. The described methods utilize catalytic chemical reactions and biological processes to facilitate the conversion, while increasing yields and reducing energy requirements.

摘要： Disclosed herein are methods and compositions of matter showing that catalytic autoxidation can be used to generate aromatic monomers from C—C linked dimers and oligomers derived from lignin. This is demonstrated by acetylating phenol-rich RCF oil and then conducting aerobic oxidation of the oligomeric fraction of poplar RCF oil with a Co/Mn/Br catalyst mixture in acetic acid. This reaction yields a collection of oxygenated aromatic monomers that represent a 17% increase in monomer yield compared to the RCF process alone.

摘要： The provided methods and systems describe the breakdown of plastic materials into valuable products, thereby both eliminating waste and providing reusable materials. The described systems and methods utilize catalytic depolymerization and biological funneling via bacteria, which may reduce the costs of recycling plastics in terms of expensive catalysts, energy, and time. Advantageously, some embodiments may target mixed plastic streams, which due to having multiple chemical compositions, may not be easily recycled via conventional recycling techniques. Such mixed plastic streams are currently often discarded (e.g., landfilled) rather than recycled due to the cost and effort required for separating the various compositions present.
