Biogas valorization takes advantage of mature technologies for power generation like micro-turbines, improved fuel cells and other options involving heat production and vehicle use (Trendewicz & Braun 2013).Furthermore, the improvement of high-rate anaerobic processes (van Lier 2008) and co-digestion of liquid effluents with organic solid wastes (Liu et al. 2009) entails enhanced biogas

LCA studies of biogas production and utilization differ in terms of the scope and the method for impact assessment. Since the outcomes of an LCA are highly dependent on the scope, the method for assessing the environmental impact and other assumptions for the calculations, direct comparisons between different LCAs are not very useful. In the The initial LCA analysis was focused on the performance of the upgrading of biogas, relative to conventional CHP utilisation: Scenario 1: Biogas utilisation for Combined Heat and Power (CHP); Scenario 2: Biogas Gas-to-Grid (GtG); andScenario 3: Biogas to Vehicle Fuel. The system boundaries for the analysis are shown in Figure 1. 2021-02-15 Biogas produced by AD is considered to have a high saving potential with respect to greenhouse gas (GHG) emissions (EC, 2009). However, beyond that, other environmental implications of biogas production are still unclear despite quite a few life cycle assessment (LCA) studies having been carried out.

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 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). Biogas production upon acidification, and therefore energy yield, was higher, reaching up to 22.88 m 3 CH 4 ton −1 feed (229.25 kWh ton −1 feed), compared with 17.45 m 3 CH 4 ton −1 feed (174.85 kWh ton −1 feed) for the case where no pretreatment was performed. LCA has been conducted on photovoltaic systems ( Sherwani and Usmani, 2010), biogas ( Ishikawa et al., 2006), biomethane ( Uusitalo et al., 2014), bioethanol production ( Sandilands et al., 2009 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.

In this study, energy consumption and environmental Feb 22, 2019 The LCA framework has been widely applied to evaluate the Maize used for biogas production was assumed to be ensiled during storage. To execute the goal of the current master's thesis a Life Cycle Assessment (LCA) was conducted following the guidelines set in the ISO 14044:2006 standard. May 9, 2017 and Life Cycle Assessment of methane production via biogas upgrading and power to gas technology. Applied Energy, Elsevier, 2017, 192, The study is based on Life Cycle Assessment (LCA) according to Global Warming Potential (GWP), Cumulative Energy Demand (CED), ReCiPe midpoint/ endpoint The general goal of LCA for biogas energy systems is to determine the environmental impacts of producing and utilizing biogas as an energy source, i.e.

LCA of bio gas production and use. The environmental impacts of biogas production processes vary according to regional farming procedures and, therefore, the soil, cli mate conditions, crop yield, In this study, life cycle assessment (LCA) methodology was used to assess the environmental impacts associated with biogas digesters in Vietnam. Handling 1,000 kg of liquid manure and 100 kg of solid manure in a system with a biogas digester reduced the impact potential from 4.4 kg carbon dioxide (CO 2 ) equivalents to 3.2 kg CO 2 equivalents Abstract This paper provides a comprehensive review of 48 studies on the Life Cycle Assessment (LCA) of biogas production from 2006 to 2018 (13 years).

At present, biogas in Switzerland is mainly produced from sewage sludge, slurry, and biowaste. If the co-digestion with higher shares of substrates made from energy crops increases significantly in future, the produced biogas cannot comply with the thresholds for a fuel tax reduction anymore.
