FIELD: production processes.
SUBSTANCE: method includes preparation of solid bio-waste products containing cells and water related to cells and their delivery to the following stages: arrangement of sufficient pressure in solid bio-waste products for maintaining of fluidity; heating of solid bio-waste products under pressure up to first temperature sufficient for cells breakage and release of water related to cells and extraction of carbon dioxide from solid bio-waste products with formation of suspension of carbonised material containing carbonised broken cells of solid bio-waste products; cooling of suspension; release of pressure in suspension by means of carbon dioxide separation; removal of at least some part of water related to cells released from suspension, this results in production of at least partially dehydrated product form carbonised cells of solid bio-waste products. In the other version method includes preparation of biomass containing at least 10% of water; suspending of biomass for getting of run through suspension using method chosen among grinding, adding of fresh or recirculated water, water vapour and their combination; use of biomass of sufficient pressure in suspension for maintaining of fluidity and biomass formation under pressure; heating of biomass under pressure up to first temperature sufficient for formation of water suspension of carbonised material, carbon dioxide and free water; cooling of suspension of carbonised material; release of pressure in suspension of carbonated material from biomass; separation of carbon dioxide from suspension of carbonated mass; and removal of at least some part of free water from suspension of carbonated biomass, this results in production of dehydrated carbonised biomass with reduced oxygen content.
EFFECT: invention allows removing silt in economic and environment-friendly way with production of renewable fuel with positive calorific capacity.
