A method of processing food waste in a food waste digester using processed tagua seeds as a support medium for micro-organism that digest food waste into a biodegradable liquid.

The present invention relates to a carcass treatment system 1. Such a carcass treatment system 1 ferments and decomposes carcasses by hyperthermophile of 85 to 110° C. and aerobic conditions, and comprises a mobile fermentation process unit 3 for transferring to an onset site of disease and treating the livestock carcass by hyperthermophile; or a burial fermentation process unit 5 for excavating a burial site 6 near the outbreak site of disease and treating the livestock carcass by hyperthermophile; a base treatment unit 7 for secondarily processing the livestock carcass treated primarily by the mobile fermentation process unit 3 or the burial fermentation process unit 5 with hyperthermophile, wherein the primary treatment is performed by treating with hyperthermophile at fermentation temperature of 85 to 110° C. for 8-15 days to decompose flesh of the carcass, and the secondary treatment is performed by treating with hyperthermophile for 2-4 weeks.

An organic waste digestion and decomposition system includes a digestion chamber, a drain tank, and a discharge tank. The digestion chamber is configured to digest an organic waste mixture disposed therein to produce a liquid digestate. The digestion chamber includes a recirculation spray head configured to spray a first portion of the liquid digestate into the digestion chamber and a drain pan configured to enable the liquid digestate to exit the digestion chamber. The drain tank is configured to receive the liquid digestate from the digestion chamber and includes a first pump configured to pump a second portion of the liquid digestate from the drain tank back to the digestion chamber. The discharge tank is in fluid communication with the drain tank and is configured to receive the liquid digestate from the drain tank and enable the liquid digestate to be discharged from the organic waste digestion and decomposition system.

The present disclosure relates to a method of producing bioplastic pellets using livestock manure, the method including steps of: making a first mixture livestock manure, sawdust, a microbial medium and a microbial preparation; (2) making a fermentation product by stirring the first mixture; (3) making an aged product by aging the fermentation product; (4) making a dried product by drying the aged product; (5) making compost powder by crushing the dried product; and (6) mixing the compost powder, synthetic resin, a binder, a dispersing agent and a slip agent together to obtain a second mixture, and cutting the second mixture into pellets during extrusion. The method has an advantage in that it is possible to improve processability by reducing the water content of decomposed livestock manure containing a lot of water and to improve mechanical properties.
