Abstract
A fuel product derived from waste products and processes for using and forming the products are provided. Broadly, the fuel product comprises a self-sustaining body formed from a homogenous mixture including solid components derived from livestock waste (e.g., swine manure) and a second waste product different from the livestock waste (e.g., sawdust or paper). The mixture has a moisture content of from about 10-40% by weight and the formed body has a bulk density of from about 20-40 lbs/ft.sup.3. The mixture or formed body is heated to a temperature of at least about 800.degree. F. in order to produce at least about 5000 BTUs of energy per pound of mixture or body heated.
Claims55
A process for forming a fuel product from livestock waste comprising the steps of:
- (a) forming a mixture comprising a quantity of solid components derived from the livestock waste and a second waste product different from said livestock waste, said solid components having a moisture content prior to said forming step, and said formed mixture having a moisture content lower than said solid components moisture content;
- and
- (b) forming the mixture resulting from step (a) into a self-sustaining body having a bulk density of from about 20-40 lbs/ft.sup.3.
A process of using a fuel product to produce energy, said process comprising the steps of:
- (a) providing a blended mixture comprising a quantity of solid components derived from livestock waste and a second waste product different from said livestock waste, said solid components having a moisture content of from about 60-80% by weight based upon the total weight of the solid components taken as 100% by weight, and said formed mixture having a moisture content of from about 10-40% by weight based upon the total weight of the formed mixture taken as 100% by weight;
- and
- (b) heating said blended mixture to a temperature of at least about 800.degree. F.
A process of using a fuel product to produce energy, said process comprising the steps of:
- (a) providing a blended mixture comprising a quantity of solid components derived from livestock waste and a second waste product different from said livestock waste, said second waste product having an average particle size of less than about 0.75 inches;
- and
- (b) heating said blended mixture to a temperature of at least about 800.degree. F.
A fuel product comprising a self-sustaining body comprising a blended mixture including solid components derived from livestock waste and a second waste product different from said livestock waste, said solid components having a moisture content and said blended mixture having a moisture content lower than said solid component moisture content, said body having a bulk density of from about 20-40 lbs/ft.sup.3.
