The objective of this study was to assess the status of biogas production and its effects on the environment due to greenhouse gases (GHG) and other environmental impacts. In this work, 15 life cycle assessment (LCA) studies of biogas systems from around Europe were reviewed.
The existing targeted processes of LCA on biogas projects include methane production (El-Mashad and Zhang, 2010), biogas utilization pathways , and by-products reuse modes (Rehl and Müller, 2011).
With a life cycle assessment (LCA), the environmental impacts due to the diges-tions of these substrates can be analysed. In this report life cycle inventory datasets of biogas production from the following substrates are in-vestigated: maize silage, sugar beets, fodder beets, beet residues, molasses, and glycerine. Further- Biogas is composed mainly of methane (CH4) and carbon dioxide (CO2) produced from waste, residues, and energy crops through anaerobic digestion (AD). Biogas is a renewable energy sources which are 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. No review article has analyzed biogas LCA from manure from a global perspective. Thus, this paper presents a systematic review of peer-reviewed articles involving life cycle assessment (LCA) of manure biogas production systems, analyzing the significant factors, which lead to differences in the LCA studies, carried out.
In this study, life cycle analysis (LCA) has been applied to evaluate the environmental impacts of biogas production and utilisation substituting for grid electricity, natural gas grid and transport fuels, with a focus on Greenhouse Gas (GHG) emissions. The results demonstrate significant reductions in greenhouse gas emissions for the biogas as a 2015-08-15 · Biogas production through the anaerobic digestion of energy crops is the selected study case for applying the integrated methodology of WF and LCA. Three kinds of crops – maize, sorghum and wheat – were selected, being the most widespread in the Italian territory for bioenergy production (González-García et al., 2013, Buratti et al., 2013). Biogas production is an excellent way of using organic waste (LCA) of multiple biogas production and utilization pathways in order to identify areas where further mitigation of potential Introduction: LCA’s for biogas production §Many LCA studies in the recent years on biogas production àLarge variation of results àHard to simplify §Different reasons for the variations: • Methodological differences - Functional Unit - System Boundaries - Methodological Assumptions • Complexity of natural systems 4 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 .

The LCA is of the attributional type, i.e. it describes the environmental impact related to the future (steady state) operation of a system for biogas production and injection into the grid and to the conventional natural gas system.

2015-08-15 · Biogas production through the anaerobic digestion of energy crops is the selected study case for applying the integrated methodology of WF and LCA. Three kinds of crops – maize, sorghum and wheat – were selected, being the most widespread in the Italian territory for bioenergy production (González-García et al., 2013, Buratti et al., 2013).
The adoption of technologies such as biogas is generally promoted by environmental issues [14], specifically for waste disposal. assessment (LCA) to commercial biogas production provides a valuable tool for evaluating the environmental impact of waste management processes and assists in economic decision-making. Using life cycle assessment as a basis for evaluating the biogas production at the Swedish Biogas LCA was used in the current study to compare the impact assessment for biogas production from two different crops: the most widely used maize crop and alfalfa.
