Goal And Scope

Abstract Increasement of demand for gayo arabica coffee has influenced the coffee industry, either in increasing the coffee production and also in increasing the usage of coffee machinery and equipment significantly. However, combustion of oil fuels result the emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) which increase the effect of greenhouse gases from the coffee production process. This study aimed to analyze the direct impact of gayo coffee production towards environment using the Life Cycle Assessment (LCA) method, including several stages such as (1) the goal and scope definition, (2) the inventory analysis, (3) the impact assessment, and (4) the interpretation. Results of this study showed that the energy needed to process 1000 kg of coffee was 7.67 MJ, while the produced liquid waste was 5 953.2 kg. The value of the global warming impact on the coffee life cycle was 56 807 165.63 CO2eq.

Building Integrated Photovoltaic

Building integrated photovoltaic (BIPV) technology provides an aesthetical, economic, and technical solution for electricity self-sufficiency in buildings. As one of the most promising technologies for solar energy harvesting in urban areas, BIPV technology provides multiple benefits for buildings, including power generation from renewable energy resources, the replacement of traditional wall cladding, daytime lighting, heating/cooling load reduction, etc. This paper systematically reviews the progress of recent research on the electrical, thermal, optical, and overall energy performances of BIPV systems. Furthermore, based on the literature review on the energy payback time and the greenhouse-gas emission of various BIPV technologies, the research progress of the life-cycle assessment of BIPV systems is also discussed. It is anticipated that the review results can provide meaningful reference and support for the research and development of BIPV technology.

Goal And Scope Definition

AbstractIn 2013 the population of dairy cattle in Indonesia had reached 636,000 head with a 4.61% growth rate per year. The inputs were energy, water, and feed. These inputs produced outputs, such as emissions, solid waste and liquid waste. This research compared the maintenance systems in modern farms and local farms. The data were collected from 30 local farmers and one modern farm. This research used the life cycle assessment (LCA) method. LCA is based on ISO 14040. LCA consists of several stages: the goal and scope definition, inventory analysis, impact assessment, and interpretation. This research used the cradle to gate concept and fat corrected milk (FCM) as the function unit. The impacts of these activities could generate global warming potential (GWP), acidification potential (AP), and eutrophication potential (EP). The calculations showed that the systems in local farms had the greatest emissions result over all impacts. In the case of local farms, the GWP was 2.34 kg CO

Depth Analysis

Abstract The German and European climate action programs and the ongoing discussion of resource efficiency require an in-depth analysis of the building sector, especially with the background of the German refurbishment backlog and high energy demands of the German building stock. A Life Cycle Assessment (LCA) on the city quarter level allows fast and efficient evaluation of environmental impacts, emissions, and energy demands of densification in urban areas. This study presents LCA results for a specific urban city quarter. Thereby environmental and energetic values for specific building ages are developed and used to conduct LCA for the building construction and technical building services components. A 3D city model in CityGML-format of residential buildings serves as the basis for assessment. The results can be used to identify decisive drivers of energy demands and emissions and the saving potentials of different building development scenarios.
