Produção de biogás no Brasil e na Espanha: um estudo comparativo

Abstract

As the world's population grows, waste generation and consumption needs increase. As a result, there is a growing search for solutions that meet both population and environmental needs. One of the possible ways for this to occur is the generation of renewable energy from inexhaustible resources. Among the sources of resources used is biogas, which uses organic raw materials (biomass) to generate electrical, thermal, biofuel, biofertilizer, among other products, while reducing the environmental liability of residues / detritus. The present study sought to make a comparison of biogas production between Brazil and Spain, showing similarities, differences and opportunities for them, since both present potentials and broad perspective for biogas generation. For this, a systematic bibliographic review on the subject was conducted and an interview with a Spanish member of AEBIG. Through this study, we can include both Spain and Brazil, or the type of biomass most used in livestock. As most commonly used technologies are distinct, it is the most widely used type of CSTR in Spain and the most widely used UASB in Brazil. The results show that both countries present as large electric power generation from biogas, but with different focuses, being this energy, destined mostly for self-consumption.
