high energy content. 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.

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.

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. The results show a comparable total impact using alfalfa in comparison with maize. In this study, a life-cycle assessment (LCA) of biogas production from the microalgae Chlorella vulgaris is performed and the results are compared to algal biodiesel and to first generation biodiesels.

För att räkna på miljöpåverkan av de olika tekniska lösningarna för lytande biogas (LBG)- f produktion, utfördes livscykelanalys (LCA). Det är en systemanalys där man jämför miljöprestanda för olika lösningar till samma funktion. Här jämfördes systemlösningarna för produktion av 1 kg LBG.

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. 2.

LCA of Biogas Through Anaerobic Digestion from the Organic Fraction of Municipal Solid Waste (OFMSW) Compared to Incineration of the Waste Lisa Bolin1, Hui Mien Lee2 and Mattias Lindahl1 1 Environmental Technology and Management, IEI, Linköping University, Sweden 2 Singapore Institute of Manufacturing Technology, Singapore Mattias.Lindahl@liu.se 2019-06-20 Upgrading consists of a range of purification processes aimed at increasing the methane content of biogas to reach specifications similar to natural gas. In this perspective, an environmental assessment, based on the Life Cycle Assessment (LCA) method, of different upgrading technologies is helpful to identify the environmental characteristics of biomethane and the critical steps for improvement. 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 . LCA can be In that regard, (organic) waste of production processes can be object of anaerobic digestion, generating biogas; it can environmentally benefit by means of waste treatment (and consequent avoided environmental impacts) and electricity production. Additionally, the life cycle assessment (LCA) is the most comprehensive tool for environmental LCA is a useful tool for sustainability assessment in biogas systems. There are several studies of LCA in biogas.

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. The results show a comparable total impact using alfalfa in comparison with maize.

Using life cycle assessment as a basis for evaluating the biogas production at the Swedish Biogas A detailed LCA study of hydrogen production from biogas ATR using the BioRobur technology has been performed. LCA analysis has been also conducted for other two conventional processes for the production of hydrogen from biogas: the steam reforming and water hydrolysis (a biogas-fueled Internal Combustion engine (ICE) followed by an Electrolyser). Therefore, a LCA was carried out for the production of biomethane ready for the injection into the Italian distribution natural gas grid.A mix from different waste sources (cattle manure and slurry, pig slurry, Citrus industry by-product, chicken manure, manure from broilers, triticale silage and waste from vegetable cleaning) is considered for biogas and digestate production.

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).

This paper biogas production in a co-digestion system of pig slurry, maize and trit- icale. The results indicate clearly the importance of the process steps biomass cultivation. (substrate production) and the biomass conversion to biogas as well as biogas The LCA results show that the disposal of food waste using BioHiTech's been reported to enhance biogas production from anaerobic digesters at WWTPs. The environmental impact analysis in AD life cycle assessment is also discussed. of biogas production, technology and policy framework in Germany.

LCA of Biogas production from purchased substrates In order to improve the yield of biogas plants, operators often purchase or cultivate substrates with high energy content. The environmental impacts due to the digestions of these substrates can be analysed with a life cycle assessment (LCA).
