The aim of the work was to estimate the feasibility of utilizing fresh bio waste and ensiled green cut for the bioliq process, which includes downstream entrained flow gasification in a GSP gasifier. Fast pyrolysis experiments are carried out after leaching and mechanical dewatering. The solid and liquid products of the green cut waste contained up to 94% of the energy content of the starting material. The pyrolysis products are chemically similar to those of other biomasses, except for a distinct share of fatty acids due to the variability of the feedstock. The results show that the use of these leached and dried waste materials in the bioliq process is possible.
