A method for treating carbonaceous material, the method includes a) providing a first carbonaceous material CM1 contaminated with micro-pollutants and/or microplastics, and providing a second carbonaceous material CM2 free of micro-pollutants or microplastics, b) subjecting the first carbonaceous material CM1 to hydrothermal gasification in a HTG reactor, thereby producing an inorganic solid residue, a first gaseous fraction G1 comprising CH.sub.4, CO, CO.sub.2 and H.sub.2 and a filtrate F1 free of micro-pollutants or microplastics optionally containing readily biodegradable carbons such as VFAs, c) subjecting the second carbonaceous material CM2 together with at least part of the filtrate F1 to an anaerobic treatment step in an anaerobic tank, leading to a digestate free of micro-pollutants or microplastics and optionally a second gaseous fraction G2 containing CH.sub.4 and CO.sub.2. An installation for treating carbonaceous material is also provided.

A system including biogas purification and provides biogas as feedstock to a solid oxide fuel cell. The biogas purification treatment process provides a polished biogas that is substantially free of carbonyl sulfides and hydrogen sulfide. The system uses a biogas treatment apparatus, that includes apparatus such as a packed columns, comprising copper oxide or potassium permanganate packing material, and an activated carbon component configured to treat the biogas by polishing it to remove carbonyl sulfides and deleterious trace residues, such as hydrogen sulfide, that were not removed by any prior bulk H2S removal steps. In addition, an oil removal device is used to remove any entrained fine oil droplets in the biogas. A polished biogas having in the range of 60% methane is charged to the fuel cell. Electricity generated may be fed into a grid or used directly as energy to charge electrical-powered vehicles, for example. Energy credits are tracked in real time and are appropriately assigned.

The present invention relates to a method for the treatment of organic matter, in particular sewage sludge, comprising the following steps: The organic matter is first thickened to increase the solids concentration. The thickened organic matter is supplied directly into a digester. The organic matter is then removed from the digester by way of a recirculation line, thermally treated and returned to the digester. The invention further relates to a device for the treatment of organic matter, in particular sewage sludge, comprising a digester, a thickener and a recirculation line, where the thickener is arranged upstream of the digester, and the recirculation line is designed to supply organic matter from the digester directly to the thermal treatment device, and to return the treated organic matter to the digester.

The present invention provides a method for treatment of biomass material by fermentation, said method comprises a pre-treatment of the biomass material by thermal hydrolysis and wet explosion, resulting in an intermediate product having a dry matter concentration above 25% and temperature above 90° C. which is to be introduced to the fermentation, wherein a part of the content of the digestion tank used for the fermentation is recirculated and mixed with a part of the intermediate product from the pre-treatment.

The present invention relates to a method for the treatment of organic matter, in particular sewage sludge, where the organic matter is first fed to a disintegration system. The organic matter is then subjected to thermal hydrolysis in the disintegration system to form disintegrated matter. The disintegrated matter is fed to a digester in which the disintegrated matter is at least partially digested such that digested sludge is formed, where at least part of the digested sludge obtained is recirculated via a recirculation line to a point upstream of the disintegration system. The invention further relates to a device for the treatment of organic matter, in particular sewage sludge, comprising a disintegration system, a digester downstream thereof, and a recirculation line for at least partially digested disintegrated matter, said recirculation line extending from a point downstream of the digester to a point upstream of the thermal disintegration system.
