Short summary
This study compares the environmental performances of the combination of anaerobic digestion and pyrolysis technologies in different regions of the world focusing on alternative uses of biogas. Using biogas as transportation fuel in Sweden has significant environmental advantages over other scenarios, biogas for heat and electricity in the power sector in Brazil and biogas for cooking in households in China.
