Technical potential for the use of landfill biogas in the replacement of fossil fuel in the urban transport of the administrative region of Campinas

Abstract

This research analyzes the use of biomethane, obtained from biogas generated by anaerobic digestion in landfills, as an alternative to diesel oil in the means of transportation of the administrative region of Campinas (RAC). With data bases and statistics information, the consumption of diesel on transportation in the region, and also waste production, were determined. It was obtained that the wastes generates 1.24 million cubic meters of biomethane per day, reflecting in 3.04 TWh of energy potential in the year. These values result in a 16.7% Diesel fleet replacement, resulting in 8.22x10^5 tCO2 equivalent avoided. Therefore, the results indicated a great potential of biomethane as an alternative for Diesel oil in the RAC, contributing to a low-carbon economy. However, non-compliance with Proconve emission standards creates a barrier to the use of biomethane in the country. Further discussion is needed for a sustainable equation.
