  • Publication number: 20250122129
    Abstract: A method for preparing an adjustable organic fertilizer is provided. The method includes providing a ratio of nitrogen, phosphorus, and potassium required for a target crop and collecting a plurality of wastes. The method includes categorizing the fertilizer concentrations of the same type of feeding substrates within the wastes separately, and adjusting the composition of the categorized wastes to form a composite feeding substrate according to the ratio of nitrogen, phosphorus, and potassium required for the target crop. The method includes subjecting the composite feeding substrate to an anaerobic fermentation process. The anaerobic fermentation process includes introducing the composite feeding substrate into an acidification tank to obtain a first mixture and introducing the first mixture into a methanogenesis tank to obtain a second mixture.

  • Publication number: 20230078503
    Abstract: A thermoplastic polyurethane composition includes a first thermoplastic polyurethane compound and a modifier formed by subjecting a modifier-forming mixture to a thermal mixing process. The modifier-forming mixture includes a second thermoplastic polyurethane compound, a copolyester modifying agent, and a compatibilizer. The copolyester modifying agent is present in an amount ranging from 5 wt % to 30 wt %, and the compatibilizer is present in an amount ranging from 0.5 wt % to 5 wt %, based on a total weight of the thermoplastic polyurethane composition. A dyeable fiber made from and a method for preparing the thermoplastic polyurethane composition are also disclosed.
