Objective: Exploring the effectiveness of two processing methods in sequential operation in order to increase the profitability of individual processes during biomass transformation and its wastes for obtaining other products.Design/methodology/approach: Processes of hydrolysis and acidification are activated by the general process to obtain biogas, resulting in a highly acidic liquid biomass. The organic acids are removed through technical procedures to be utilized on other chemical processes. Leftover wastes contain few constituents able to be decomposed, and their appropriate disposal consumes resources, so they are processed through hydrothermal carbonization in order to obtain biocarbon.Results: When vegetation biomass with high moisture content is exposed to high temperatures for hydrothermal carbonization, water evaporation takes place as well as a selective amount of some particles contained in the biomass. Leftover waste is a solid and hard material, with a high carbon concentration.Study limitations/limitations: The technical process used to extract organic acids is slow, so the removal is partial and effectiveness is reduced.Findings/conclusions: Integration of processes with sequential operation, where useful compounds are obtained and wastes produced from the first processing become raw material for the following process, originating hydrothermal carbonization, improve efficiency and attain financial profitability
