Fast Pyrolysis of Fresh Bio Waste and Ensiled Municipal Green Cut

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. A combination of green cut and organic household waste can be used to produce solid fuel, which in turn can then be used as substrate for the bioliq process. In the pyrolysis products one can not only find the usual decomposition products of lignocellulose, e.g., acetic acid, hydroxyl aldehydes, but also unexpected products such as fatty acids.
