20230391979 · 2023-12-07 ·

Bacillus subtilis SK01 and its application in plastic degradation. Bacillus subtilis SK01 collected by China Center for Type Culture Collection (CCTCC), CCTCC NO: M2020812 is used to prepare a degradable plastic that can protect Bacillus subtilis SK01 from the damage of high temperature and reduce the difference with polyene plastics in specific gravity. The plastic may be stored for more than 1 year to ensure that the microbial enzymes produced by Bacillus subtilis SK01 can achieve 49.11% of total degradation of organic solids after 153 days in an environment for composting or soil burial, and can be slowly degraded by sunlight (photodegradation) or immersion in water. Under an environment other than that mentioned above, the finished products of polyene plastics added with Bacillus subtilis SK01 are consistent with the non-degradable plastics in shelf life, satisfying the demand of a variety of polyene plastics.

SYSTEMS AND METHODS FOR OPTIMIZATION OF ENZYMES

Poly and perfluoroalkyl substances (PFAs) are extremely resistant to natural degradation. Described herein are compositions, assays, and methods for generating microorganisms capable of accelerating degradation of these products using a directed evolution strategy. A minimal media including the target carbon source of interest, creates selective pressure for microorganisms capable of degradation. Extremely slow growth rates on these alternative carbon sources is nevertheless measureable using automated image capture and processing pipeline allows one to observe very small changes in cell growth over the course of a very long period of time, thereby identifying microorganisms that could not otherwise be identified.

20230405651 · 2023-12-21 ·

A system for recovering recyclable materials from mixed waste is provided. The system processes existing municipal solid waste collections to recover recyclable materials from the waste. The system uses various separation processes sequenced with a rotating, horizontal constant-flow steam based waste processing vessel to efficiently separate high value materials such as metals and rigid plastics while additionally separating low value plastics and post-consumer commodities. The system reduces landfill load and operational costs while simultaneously providing the reduction of carbon emissions achieved with recycling post-consumer commodities.

CONVERSION OF WASTE PLASTICS TO PETROCHEMICALS

Processes and systems for converting waste plastics include feeding a waste plastic to a melt tank, and in the melt tank, heating the waste plastic to form a molten plastic. The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor. In the pyrolysis reactor, the molten plastic is heated to a pyrolysis temperature, producing a pyrolysis oil product and a liquid pitch product. The pyrolysis oil is then separated into a pyrolysis gas fraction, a light pyrolysis oil fraction, a medium pyrolysis oil fraction, and a heavy pyrolysis oil fraction.
