Renewable energy sources, including biogas, are generally considered eco-friendly. The objective of this paper is to compare the effects of differing primary and secondary biogas production processes on ecology as a whole, as well as with each other.

The environmental impacts due to the digestions of these substrates can be analysed with a life cycle assessment (LCA). 2010-01-01 In this work, 15 life cycle assessment (LCA) studies of biogas systems from around Europe were reviewed. Biogas scenarios in all the studies had lower GHG intensities than their reference systems. The study shows that the type of feedstock, e.g., maize, grass or animal manure is a determining factor for the environmental impacts of biogas systems. Biogas LCA studies provides to assess the environmental impacts from biogas production, to determine energy and material requirements and emissions and to compare different scenarios. 2012-05-01 tion of leakage of biogas during production and upgrad-ing is crucial for the environmental impact on GWP. A leakage of only a few percent of the produced gas will lead to a loss of all the gain in saved GHG-emissions. Key words: Biogas, OFMSW, MSW, LCA, Anaerobic Digestion 1.

The number of biogas plants has nearly tripled within the last seven years, from 435 plants in 2004 to 1,300 in 2011. Economic incentives for this development are provided under the Renewable Energy Law (German: EEG). eller övergödningspotentialen för produktsystemet i någon större utsträckning om biogas används istället för naturgas.

It is not intended that a detailed life cycle analysis is carried out however the Any review of legislation to support biogas production should be based on a Det är möjligt att i en upphandling främja lokalt producerad biogas för hur mycket fossilt CO2 biogasen får släppa ut ur ett LCA-perspektiv.

The LCA methodology is an important tool in the use and implementation of anaerobic digestion for the generation and use of both biogas and soil improvers. Harder et al. [15] conducted a study of wastewater sludge treatment and integrated a quantitative microbial risk analysis into the LCA results.
