摘要：
A process is provided for the biological digestion of animal carcasses. First, the carcass is cut into smaller pieces with equipment that masticates, grinds or comminutes in the presence of water to create a solid-liquid mixture. The next steps include treating the solid-liquid mixture with a special blend or combination of bacteria that have been specifically cultured to digest the carcass; the mixture is subsequently aerated to form a stabilized biomass. The stabilized biomass is aerated in an open basin to further digest and liquefy the carcass, water, bacteria mixture. From the open basin, the primarily liquid waste stream is passed to a clarifying tank where the suspended solids are precipitated as sludge, thus clarifying the liquid. Sludge is removed from the clarifying chamber and the clarified liquid is either discharged or recirculated for further use in this novel process. In the preferred embodiment of the invention, technology known as hydrolaze is used to masticate, comminute or pulverize the carcass.
