A method of diverting municipal solid waste (MSW) from a landfill that includes receiving, at a MSW processing system, a quantity of MSW, gasifying the quantity of MSW in a gasification unit to yield a syngas stream and biochar stream, converting at least a portion of the syngas to mixed alcohols in an alcohol synthesis unit, separating the mixed alcohols into one or more alcohol products, and determining a carbon offset for diverting the MSW from the landfill to the MSW processing system.

A method of gasifying carbonaceous material is described. The method comprises a first step of pyrolyzing and partially gasifying the carbonaceous material to produce volatiles and char. The volatiles and the char are then separated and, subsequently, the char is gasified and the volatiles are reformed. The raw product gas is then finally cleaned with char or char-supported catalysts or other catalysts.

Disclosed in the present disclosure is a method for producing hydrogen from woody waste through staged pyrolysis and catalytic gasification. The method includes: performing baking pretreatment on the woody waste; thermally activating aluminum smelting waste residues, and mixing the thermally activated aluminum smelting waste residues with the baked woody waste; pyrolyzing and gasifying the mixture for hydrogen production to obtain primary pyrolysis gas and a carbon-aluminum composite material; and further catalytically cracking the obtained primary pyrolysis gas by taking the obtained carbon-aluminum composite material as a catalyst.
