The present invention relates to a system for the treatment of organic waste and/or waste, particularly waste from biogas plants, slurry and the like, cut or green waste and/or sewage sludge.

Processes for upgrading of a coal product and preparing of a purified coal product are provided. The process comprises the steps of: (i) providing a purified coal composition, wherein the composition is in the form of solid particles, and wherein at least about 90% by volume (% vol) of the solid particles are no greater than about 500 ?m in diameter; and (ii) combining the purified coal composition with a solid coal feedstock, in order to create a combined solid-solid blend upgraded coal product.

Spent potlining material contains spent potliner from aluminium electrolysis cells, and at least one hydrophobic binder. The hydrophobic binder being selected from wax, a waxlike compound or mixtures thereof. A method for producing a spent potlining material includes the steps of (a) providing spent potliner from aluminium electrolysis cells, (b) comminuting the spent potliner in at least one comminuting apparatus, (c) fractionating the spent potliner through a separating apparatus, (d) mixing the spent potliner with at least one hydrophobic binder, selected from wax, a waxlike compound or mixtures thereof, in a mixing apparatus, (e) portioning the mixture obtained in step (d), (f) withdrawing the spent potlining material The steps (b) to (d) are carried out in an inert gas atmosphere. Also, spent potlining material is used as fuel in power stations and also in connection with the production of mineral wool, cement and steel.

A method of manufacturing a non-molded solid fuel using a combustible waste material includes (a) primarily crushing an inflowing waste material using a bag-tearing and crushing device, (b) separating iron from the primarily crushed waste material using a first magnetic sorter, (c) sorting the waste material, from which the iron is separated, according to the particle size of the waste material using a first oscillating multi-stage particle-size sorter, (d) secondarily crushing the waste material having a large particle size using an impact crusher, (e) separating the iron from the secondarily crushed waste material using a second magnetic sorter, (f) sorting the waste material, from which the iron is separated, according to the weight of the waste material using a wind power sorter, (g) separating the iron from a light material, and (h) pulverizing the waste material, from which the iron is separated.

The disclosure relates to the field of solid biofuels obtained by steam cracking. More particularly, the disclosure relates to a process for the treatment of lignocellulosic biomass by steam cracking in which the obtained powder is treated in order to separate the particles into two categories according to a threshold value, and each category is treated differently.

A method for grilling food on grill includes adding chipped wood charcoal having a size of at least one-fourth an inch in dimension through a food-supporting grill grate onto a grid underlying the food-supporting grill grate. The food-supporting grill grate comprising spaced bars for supporting food and providing a cooking area, and the chipped wood charcoal can be added to the grid directly beneath any portion of the cooking area by passing the chipped wood charcoal between any adjacent ones of the spaced bars. The chipped wood charcoal is ignited and food is placed on the food-supporting grill grate over the chipped wood charcoal. The food can then be cooked on the food-supporting grill grate. Without lifting any portion of the food-supporting grill grate and during the cooking of the food, more chipped wood charcoal is added through the the spaced bars of the food-supporting grill grate. The chipped wood charcoal can be added to the grid directly beneath any region of the cooking area by passing the chipped wood charcoal between any of the adjacent ones of the spaced bars.

This disclosure includes systems and methods that may be used in forest residue processing. Some systems use or include: a filter configured to filter elements based on element size, a separator configured to separate elements based on element areal density, a separator configured to separate elements based on element density, and/or a sorter configured to sort elements based on element wood fiber content.

A process and system for producing an engineered fuel product that meets customer specifications for composition and combustion characteristics is provided. The engineered fuel product is preferably a high-BTU, alternative fuel that burns cleaner than coal or petroleum coke (petcoke) and has significantly reduced NOx, SO.sub.2 and GHG emissions.

A fire starter mixture including at least about 10% and at most about 90% by weight of a biomass component, and at least about 10% and at most about 90% by weight of a fuel component. The fuel component includes at least about 10% and at most about 90% by weight of a flammable primary fuel and at least about 10% and at most about 90% by weight of a combustible secondary fuel.

This disclosure describes a method for retrofitting an existing plant. The method includes adding a fractionation process to separate bran from other components in a feedstock to the existing plant, adding a pretreatment process downstream of the fractionation process, the pretreatment process configured to receive the bran and utilize water and heat to break down cellulose and hemicellulose in the bran; adding a hydrolysis and cellulosic fermentation process downstream of the pretreatment process and upstream of the fermentation process to hydrolyze the bran with a cellulase enzyme complex cocktail and to ferment with an organism to produce cellulosic beer; and combining the cellulosic beer with starch from the grain in the existing plant into the fermentation process to increase overall yield per feedstock unit in the existing plant.
