The present invention relates to a method for solubilisation or hydrolysis of Municipal Solid Waste (MSW) with an enzyme blend and an enzyme composition for solubilization of Municipal Solid Waste (MSW), the enzyme composition comprising a cellulolytic background composition and a protease, lipase and/or beta-glucanase.

The process for producing organic molecules from fermentable biomass includes a step of anaerobic fermentation (5) producing volatile fatty acids (6), these precursors being transformed into final organic molecules by non-fermentation means. It also includes at least the following steps: a) extracting (9) at least one portion of the volatile fatty acids from the fermentation medium in such a way that the production of fermentation metabolites by the microorganisms (M) is not affected, and introducing a portion of the liquid phase (11) containing microorganisms from the extraction (9), b) synthesizing (13) organic molecules from the fermentation metabolites or from the volatile fatty acids extracted in step a)-c) continuing steps a) to b) until the final molecules are obtained, in terms of amount and quality. The invention also relates to an installation for implementing the process.

The invention provides treatments of organic waste. The invention provides a method for treating organic waste (and in particular, animal waste such as waste from a cow) and uses of a composition that is capable of generating a reactive species in methods of reducing biological degradation of organic waste, in the treatment of organic waste. The invention also provides organic waste treated by the methods of the invention and uses of this treated organic waste. The invention also provides a method for improving the production of volatile fatty acids (VFA) and medium-chain carboxylic acids (MCCAs) during anaerobic digestion (AD) of organic waste.

The invention provides for methods, devices, and systems for pyrolyzing biomass. A pyrolysis unit can be used for the pyrolysis of biomass to form gas, liquid, and solid products. The biomass materials can be selected such that an enhanced biochar is formed after pyrolysis. The biomass can be pyrolyzed under specified conditions such that a selected biochar core is formed. The pyrolysis process can form a stable biochar core that is inert and/or resistant to degradation. The biochar or biochar core can be functionalized to form a functionalized biochar or functionalized biochar core. Functionalization can include post-pyrolysis treatments such as supplementation with microbes or physical transformations including annealing and/or activation.
