Abstract
A process is provided for producing animal feed from food waste by providing a dry, pelletized, fibrous organic material. Specifically, the invention relates to methods of thickening/dewatering solids that contain substantial amounts of moisture, e.g., ground food waste.
Claims14
A process for producing animal feed from food waste, consisting essentially of the steps of:
- (a) shredding of the food waste, resulting in ground food waste;
- (b) thickening of the ground food waste through the use of an amount, effective for the purpose, of an agglomerating polymer and a synthetic organic flocculant, resulting in a low moisture product and a separate liquid phase;
- (c) adding a dry carrier to the thickened ground food waste, followed by extrusion of the thickened ground food waste and evaporation of residual moisture to produce dried food pellets;
- and
- (d) treating the liquid phase so as to provide a high purity effluent for recycling.
