Abstract
A fuel preferably pelletized and method of forming a fuel including a quantity of a natural particulate cellulosic material and a quantity of a particulate biosolid material from a bioslurry effluent derived substantially from fats, oils and grease (FOG) found in non-edible food residuals from sanitary sewer drainage (SSD). The biosolid material and the cellulosic material are substantially homogenous, preferably having a moisture content of from about 5% to about 15% by weight and at least substantially minus 5 mesh. A quantity of particulate synthetic polymeric thermoplastic fines material may be added for increased fuel energy content.
Claims9
A fuel pellet consisting essentially of a homogeneous mixture of:
- a quantity of natural particulate cellulosic material;
- and
- a quantity of biosolid material made from a dried bioslurry effluent derived from fats, oils and grease (FOG) found in non-edible food residuals from sanitary sewer drainage (SSD).
A method for preparing a fuel pellet from particulate natural cellulosic material and biosolid material consisting of:
- providing particulate natural cellulosic material having a moisture content of at least about 5% by weight;
- providing biosolid material consisting essentially of fats, oils and grease (FOG) derived from non-edible food residuals from santitary sewer drainage (SSD);
- preparing a homogenous mixture including said particulate cellulosic material and said biosolid material;
- and
- pelletizing said mixture by compressing and extruding said mixture.
