Possibilities for biogas production from waste—Potential, barriers, and legal notices

Abstract

Concentration of population and enhancement of the socio-economic development of society is related to the generation of large amounts of waste. Their accumulations have negative impact on the environment and create risks to human health. The main responsible for greenhouse gas emissions is fossil fuels, where renewable energy sources provide one of the leading solutions to the climate change issue. By providing ‘carbon-neutral’ sources of power, heat, cooling, and transport fuels, renewable energy options such as wind, solar, biomass, hydro, wave, and tidal offer a safe transition to a low-carbon economy. The report provides information on appropriate organic waste for biogas production in Bulgaria—waste from animal, plant, and domestic origin. It is shown which type of biomass has the highest energy potential and the average gas productivity of certain biological waste. Barriers and legal standards for biogas production in Bulgaria and financial conditions for the construction of biogas plants are shown in detail.
