Design of a biogas plant fed with Cladophora Sp. algae and wheat straw

The blooming of biogas plant installation undergoing wet anaerobic digestion processes is an evident trend at EU condition. The use of biological feedstocks from farm and agricultural origins together with the use of alternative feedstock like marine macroalage provide benefits in terms of waste management and avoided natural resource extraction. Nevertheless, the seasonal fluctuations of the type and amounts of feedstocks available for a specific biogas plant, together with their optimal co-digestion, can affect the overall efficiency and optimization of the biogas operations with potential drawback on the overall sustainability of the system. A proper design of the biogas plant is thus a key step to have profitable biogas-based systems.
