  • MICROORGANISMS CAPABLE OF DECOMPOSING THERMOPLASTIC POLYURETHANE, METHOD FOR DECOMPOSING THERMOPLASTIC POLYURETHANE, AND METHOD FOR SELECTING MICROORGANISMS CAPABLE OF DECOMPOSING THERMOPLASTIC POLYURETHANE
    Publication number: 20230313123
    Abstract: Microorganisms capable of effectively decompose hardly decomposable thermoplastic polyurethane, a method for decomposing thermoplastic polyurethane, and a method for selecting microorganisms capable of decomposing thermoplastic polyurethane are provided. The method for selecting microorganisms capable of decomposing thermoplastic polyurethane includes a step of burying in soil a mixed sample of thermoplastic polyurethane having urea bond and polyurethane without urea bond and a step of collecting the microorganism adsorbing to the mixed sample after confirming the urethane decomposition by infrared spectroscopic analysis of the buried mixed sample.

  • Urethane decomposing method and urethane decomposing agent
    Patent number: 10988595
    Abstract: The purpose of the present invention is to provide a novel urethane decomposing method by which urethane in the environment is treated efficiently and at a low cost, and a urethane decomposing agent. The above purpose is attained by employing a urethane decomposing method including: a step of treating a urethane-containing material to be treated using an unsaturated fatty acid; and a step of making a microorganism belonging to a Streptomyces genus and exhibiting urethane decomposing function, to act on the material treated using the unsaturated fatty acid.
