This book presents the state of the art of different biodiesel production techniques, investigates them from the life cycle assessment (LCA) perspective, and discusses biodiesel production in terms of feedstocks, production systems, and biodiesel purification and upgrading technologies

The functional unit of the LCA is 20.8 Mtoe (million tons oil equivalents) biodiesel equalling the EU25 goals for biodiesel in 2020. Land occupation and transformation are quantified for the two alternative vegetable oils, and losses throughout the product chain from cultivation over crushing to refining are inventoried. 1 Goal and Scope definition of the Life Cycle Assessment (LCA) of Biodiesel from Used Vegetable Oil (UVO) and Tallow (TME – tallow methyl ester) 1.1 Goal of the study In the last few years biodiesel has become a hot topic, which is impressively demonstrated by the large number of LCA’s published to deal with this issue for both alkali-catalyzed and enzymatic catalyzed bio- diesel production, using palm oil as raw material. 2. 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.

This study aims at determining the environmental impact of vegetable oil methyl ester (VOME) production from soybean culture in Argentina for export (B100soy ARG-CH) through a LCA. The biodiesel pathway is modelled up to the exportation port, as results can significantly change A life cycle assessment (LCA) focused on greenhouse gas (GHG) emissions from the production of microalgal biodiesel was carried out based on a detailed engineering and economic analysis. This LCA applies the methodology of the California Low Carbon Fuel Standard (CA LCFS) and uses life cycle inventory (LCI) data for process inputs, based on the California-Modified Greenhouse Gases, Regulated The first comprehensive life-cycle assessment (LCA) for soybean biodiesel produced in the U.S. was completed by the National Renewable Energy Laboratory (NREL) in 1998, and the energy inventory for this analysis was updated in 2009 using 2002 data. Request PDF | Comparative LCA of the use of biodiesel, diesel and gasoline for transportation | The energy fuels used for in the Greek transport sector are made up of gasoline consumed by It is possible to convert waste/residual products to a competitive biofuel with a good environmental profile. 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.

The functional unit of the LCA is 20.8 Mtoe (million tons oil equivalents) biodiesel equalling the EU25 goals for biodiesel in 2020. Land occupation and transformation are quantified for the two alternative vegetable oils, and losses throughout the product chain from cultivation over crushing to refining are inventoried.

These techniques have been used to assess the greenhouse gas emissions of biodiesel. More Topics on Energy Life Cycle Analysis of Biodiesel.

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.

Biodiesel är ett drivmedel liknande fossil dieselolja, men som inte består av petroleumprodukter.Biodiesel består i stället av långa kedjor av alkyl estrar såsom metyl-, propyl- eller etylestrar. Biodiesel, Bioethanol und Biogas sparen in der gesamten Lebenszyklusanalyse gegenüber den fossilen Treibstoffen deutliche Mengen an THG-Emissionen ein (Biodiesel 61 %, Bioethanol 40 % und Biogas 85 %).

Published values forenergyefﬁciencyandGHGdiffersigniﬁcantlyevenfor an individual species, and we identify three major sources of variation in these LCA results. By providing Complementary to VITO’s demonstration project on the use of biodiesel as engine fuel (including on the road emission measurements), a comparative life cycle assessment (LCA) has been performed for rapeseed methyl ester (RME) and fossil diesel fuel. It addressed in details the interaction between LCA and induced land use change (ILUC) for biodiesel. Relative to the conventional petroleum diesel, soy biodiesel could achieve 76% reduction in GHG emissions without considering ILUC, or 66–72% reduction in overall GHG emissions when various ILUC cases were considered. A 1998 LCA study by the National Renewable Energy Laboratory (NREL) concluded that pure soybean based biodiesel (B100) and 20% biodiesel blend (B20) used on urban buses could reduce the petroleum fuel consumption by 95% and 19%, respectively, and the CO2 emissions by 78% and 16%, respectively (Sheehan et al., 1998).
