These results suggest that the impacts generated by the production of methane from microalgae are strongly correlated with the electric consumption. Comparative cradle-to-grave life cycle assessment of biogas production from marine algae and cattle manure biorefineries Bioresour Technol . 2017 Nov;244(Pt 2):1470-1479. doi: 10.1016/j.biortech.2017.05.143. 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.

In Europe, the common biogas (BG) production process is the anaerobic digestion of agricultural waste, manure, and energy crops; then biogas, or biomethane (if the plant has an upgrading step) is currently fed to an internal combustion engine for electricity and heat production. 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). The objective of this MSc thesis is to examine the life cycle assessment (LCA) impacts of bio-gas/biofuel production within a system that may treat different types of organic waste substrates. The purpose is to understand how life cycle environmental impacts of biogas/biofuel production is influ- LCA is often used to compare energy and carbon balances for production and use of different fuels. As such, LCA is a key tool used in assessing sustainability of biofuels. For example, U.S. policy provides tax credits for companies that blend renewable fuels with petroleum-based fuels.

(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.

In the endeavor of optimizing the sustainability of bioenergy production in Denmark, this consequential life cycle assessment (LCA) evaluated the environmental impacts associated with the production of heat and electricity from one hectare of Danish arable land cultivated with three perennial crops: ryegrass (Lolium perenne), willow (Salix viminalis) and Miscanthus giganteus. For each, four 109 Economics and Environmental Impact of Biogas Production as a Manure Management Strategy Cady R. Engler1, Ellen R. Jordan2, Marshall J. McFarland3, and Ronald D. Lacewell4 1Associate Professor, Department of Agricultural Engineering, Texas A&M University 2Professor and Extension Specialist, Texas A&M Research & Extension Center-Dallas 3Resident Director of Research, Texas A&M Research could be conducted to address the uncertainties in an LCA study in order to improve the reliability of the results (Clavreul et al. 2012). In this paper, the factors affecting biogas production from AD and coAD of food waste are reviewed so as to provide insights to improve the biogas production performance. In a biogas plant to generate heat and electricity is sustainable in economic and environmental terms. To answer this question and assess the environmen-tal performance of miscanthus-based biogas production, a Life-Cycle Assessment (LCA) was conducted according to the ISO standards 14040 and 14040 (ISO, 2006a,b). The 2016-02-01 · 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., energy and material requirements as well as emissions to the (biotic and abiotic) environment.

These results suggest that the impacts generated by the production of methane from microalgae are strongly correlated with the electric consumption. Jan Lask Alejandra Martínez Guajardo Jan Weik Moritz von Cossel Iris Lewandowski Moritz Wagner"Comparative environmental and economic life cycle assessm 1 LCA screening of biofuels ‐ iLUC, biomass manipulation and soil carbon by Jannick H Schmidt and Miguel Brandão, 2.‐0 LCA consultants, Aalborg, 29th May 2013 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 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. What you will be doing Life-cycle assessment (LCA) is a holistic approach for evaluating the global impacts of different products and processes. Agricultural production activities are generally complex, i.e.

LCA can be from biogas produced in industrial scale biogas plants..148 Table 3.21: Weighted ecol. effects of the application below gap scenario, electricity generation from biogas produced in industrial scale biogas plants..152 LCA is a useful tool for sustainability assessment in biogas systems. There are several studies of LCA in biogas. A general framework for biogas production has been established by other authors in independent studies. However, the recent studies focus on particular stage improvements or new technologies implementation.

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.
