Advanced Biomethane Production Via Gasification Using Blends of Lignocellulosic Biomass and Sludge

Short Introductive summary

With the rise in fossil natural gas prices and the ongoing decarbonization of Europe’s energy and transport systems, there is an undeniable need to increase renewable gas production capacity, especially biomethane production. This study explores a sustainable approach to increasing biomethane production on a European scale through the thermochemical recovery of wastewater treatment plant sludge. Gasification of these wastes produces syngas, which, combined with green hydrogen from water electrolysis, enhances biomethane production. The innovative aspect of this work lies in identifying and addressing critical technical and operational challenges within the equipment, particularly in the dryer, gasifier, and syngas cleaning systems. The sludge characterization revealed an ash content of 39.4%, which poses challenges for gasification technology. A high ash content can cause blockages and agglomeration in the reactor, which suggests the need for pre-treatment of the sludge and co-gasification with biomass with a low ash content. The proposed concept offers an environmentally friendly solution for converting waste into renewable gases, effectively meeting the challenges of high moisture and ash content.
