Life Cycle Assessment of Biogas Production with Algae Substrate

F. Romagnoli, J. Pubule & D. Blumberga
Macroalgae, during their growth, have the capacity to assimilate nutrients and thus subsequent harvesting of the algal biomass recovers the nutrients from biowaste sources. Therefore, the use of biowaste as algae nutrient during the growing phase, will give the possibility to transform negative environmental externalities in positive mainly in terms of eutrophication and climate change impact categories. Meantime the direct use of CO2 produced during the plant processes is becoming a large factor for the...
