Using Life Cycle Analysis (LCA) methodology, this report analyzes the GHG emissions of biodiesel from CPO. LCA was selected in order to analyze GHG emissions as a result of biodiesel production from CPO in Indonesia, with research limitations delineated to the plantation, refinery, and B20 blending station production stages.

This should be the first (and probably the last) page you will need to get information 1996-09-01 Biodiesel LCA. The details of this section are based on a report commissioned by DEFRA and carried out by the Resources Research Unit of Sheffield Hallam University in January 2003. The report entitled “Evaluation Of The Comparative Energy, Most LCA studies of biodiesel have focused on environmental impacts of biodiesel derived from different bioresources, e.g., soybean, rapeseed, and algae [17–21]. The effects of algae-derived biodiesel used in the passenger cars could be net positive or negative, depending on the algae cultivation and conversion processes from algae to biodiesel [ 18 ]. LCA studies have shown that biofuels from different cropping systems producing ethanol or biodiesel can reduce greenhouse gas emissions and non-renewable energy production, and increase other impacts such as eutrophication and acidification related to nitrogen release .

This is one of the key conclusions of a life cycle analysis (LCA) conducted by the Institute for Product Development at the Technical University of Denmark. Several life cycle analyses have been carried out for biodiesel based on animal The LCA study was conducted through three main stages including agricultural activities, oil milling, and transesterification process of biodiesel production. Palm oil biodiesel production results in the production of 1627.748kgCO2-eq of GHG and energy consumption of 12449.48MJ per ton PME. This article presents mass balances and a detailed life cycle assessment (LCA) for energy and greenhouse gases (GHGs) of a simulated microalgae biodiesel production system. Key parameters of the system include biomass productivity of 16 and 25 g m 2 day 1 and lipid content of algae of 40% and 25% for low and normal nitrogen conditions respectively.

The study includes data collection and calculation of LCA results for United Plantations Berhad’s palm oil production 2004-2018. The study was undertaken during the period January to February A major conclusion from LCA analyses of algal biofuels pathways is that the biomass yield and chemical composition of algal strains present large variability of values, depending on the inputs and technology options for algal growth. The effects of the variation of key parameters on the LCA results should be properly addressed in a broad of existing LCA models and used them for evaluating the environmental footprint of biodiesel and competing fuels (e.g. diesel) in Canada.11 Energy balances were calculated using Canadian data and diff erent soft ware.

The global biodiesel market Life cycle assessment (LCA) can be used to elucidate the net GHG balance of biofuels. Although a comprehensive LCA of various fuels has been conducted for During the lifecycle of biofuels, emissions arise during biomass feedstock 2003 ), the number of full LCA studies on biofuels on these impacts is very small. Jan 18, 2012 We analyse the use of life cycle analysis (LCA) for estimating the carbon intensity of biofuel production from indirect land-use change (ILUC). Nov 30, 2011 Introduction.

MATERIAL AND METHODS . In this study, LCA method is used as a tool for compara- tive evaluation of alkali-catalyzed and enzymatic cata- lyzed biodiesel production process with palm oil as the oil source. The environmental load produced The biodiesel produced from microalgal oil has the following fuel properties (Table 6): ester content 99.8%, cetane number 46.31, iodine value 70.04 gl 2 100g-1, degree of unsaturation 74.5%, saponification value 211.8, long-chain saturated factor 7.5%, cold filter plugging point 7.09°C, cloud point 6.87°C, allylic position equivalents 66.0 The Kyoto protocol and the EU Directive 2009/28/EC focus their attention on the reduction of greenhouse gases (GHG) emissions. The use of biofuels in the transport sector is one of the main measures proposed. This paper evaluates the environmental impact, in terms of GHG emissions, of the production and use of rapeseed biodiesel, comparing the results with conventional diesel.
