Abstract
A combustible pellet comprising municipal solid waste. The pellet has a water content of less than 10% by weight and a fuel value of at least 10,000 BTU. A process for the forming of a combustible pellet from municipal solid wastes, comprising the steps of removing solid hazardous waste from said municipal solid waste; subjecting the municipal solid waste so obtained to at least one step to separate recyclable products therefrom; and subjecting the resultant product to a shredding and a pulverizing step. A fluff with a water content of less than 10% by weight is obtained. The fluff is compacted to form a combustible pellet.
Claims38
A combustible pellet produced by a method comprising:
- a) removing hazardous waste and recyclable products from municipal solid waste to form recyclable-free, hazardous waste-free municipal solid waste, wherein the recyclable-free, hazardous waste-free municipal solid waste is approximately or completely free of glass, metals, plastics, and paper;
- b) treating the recyclable-free, hazardous waste-free municipal solid waste to form a fluff;
- c) adding at least one waste substance having a fuel value of at least 10,000 BTU per pound after (b);
- and
- d) compacting the fluff with said at least one waste substance to form a combustible pellet having a fuel value of at least 10,000 BTU per pound.
