  • Patent number: 11453607
    Abstract: A process for enhanced anaerobic digestion of sludge by alcoholization of food waste, comprising steps of: (1) ethanol prefermentation of food waste—feeding the food waste having been crushed into a uniform grain size into an ethanol production reactor, where the food waste is subjected to rapid and efficient anaerobic fermentation activated by addition of yeast and pH adjustment to produce ethanol and obtain a fermentation broth and a fermentation residue; (2) sludge pretreatment—pretreating the sludge after mixing with the fermentation residue; and (3) methanogenesis of anaerobic digestion—subjecting products resulting from the sludge pretreatment to be mixed with the fermentation broth and then to methanogenesis of anaerobic digestion in a methane production reactor. With this process, the sludge and the food waste can be treated efficiently via multi-phase reactions, and the resource recovery and biogas quality can be enhanced.

  • Publication number: 20220282037
    Abstract: A high-barrier biodegradable Doypack and a preparation method therefor. The Doypack consists of two parts, a high-barrier biodegradable self-sealing strip and a five-layered composite high-barrier biodegradable Doypack body. The main base materials of the high-barrier biodegradable self-sealing strip are PLGA and PPC that have excellent barrier performance; and the five-layered composite high-barrier biodegradable Doypack body consists of single side glossy white Kraft paper, a bonding layer, a first barrier layer, a second barrier layer, and a heat-sealing layer, which are integrally formed by using a process combining four-layer co-extrusion and lamination. Compared to conventional non-degradable Doypacks, the high-barrier biodegradable Doypack is substantially equivalent in terms of the physical and mechanical performance and heat-sealing performance, but has a superior barrier performance, and is biodegradable.
