Nils Rettenmaier . EUROCLIMA Workshop Campinas, Brazil, 30 November 2011. ifeu – Institute for Energy and 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 These LCA results have been compared to LCA results of other fuels to have a better insight of advantages and drawbacks of algal biodiesel. These assessments are based on inventories already published (30, 31) and included in the Ecoinvent database and deal with rapeseed methylester, soybean methylester, palm methylester, and oil diesel.

Nov 30, 2011 Introduction. • Life cycle assessment (LCA) of biodiesel. • LCA methodology. • Biofuels versus conventional (fossil) fuel. • Jatropha 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). The LCA study was conducted through three main stages including agricultural activities, oil milling, and transesterification process of biodiesel production.

LCA can be used to assess potential greenhouse gas (GHG) emissions reductions associated with biofuels [3, 4, 5, and 6]. A biofuel's life-cycle GHG emissions

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 ].

With the advantage in terms of raw LCA of biodiesel from Jatropha, oil palm and soybean. Nils Rettenmaier . EUROCLIMA Workshop Campinas, Brazil, 30 November 2011. ifeu – Institute for Energy and The use of palm oil as a biofuel has been heavily debated for its land-use conflict with nature and its competition with food production, being the number one cooking oil worldwide. In that context, we present a life cycle assessment of a palm oil production process yielding both biodiesel and cooking oil, incorporating the land-use impact and evaluating the effect of treating the palm oil Life cycle assessment (LCA) and techno economic analysis (TEA) of algal biomass and biodiesel production from pyrolytic substrate Xuefei Zhao a, Zhiyou Wenb, Kurt A Rosentrater c a Department of Agricultural and Biosystems Engineering, Iowa State University, Ames, IA 50011, USA BD Biodiesel GTAP Global Trade Analysis Project BETO Bioenergy Technologies Office GV Gasoline vehicle LCA system boundary: determined by LCA scope and broad policy context Methods for co-products in biofuel LCAs: need to address broad issues (e.g., food and fuels; Life cycle assessment (LCA) has been widely used to analyze various pathways of biofuel preparation from “cradle to grave.” Effects of nitrogen supply for algae cultivation and technology of algal oil extraction on life cycle fossil energy ratio of biodiesel are assessed in this study.

Methanol has been the most commonly used alcohol in the commercial production of biodiesel. In Europe, biodiesel is widely available in both its neat form (100% biodiesel, also known as B100) and in blends with petroleum diesel.

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.

En annan form av bioenergi är biodrivmedel, exempelvis etanol och biodiesel. The emphasis is increasingly on renewable sources including wind, solar, geothermal, biomass based biofuel, photovoltaics or energy recovery from waste.

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

No potential conflict of interest was reported by the authors. This paper compares the environmental impacts over the entire life cycle from biodiesel from rapeseed and conventional diesel.

of the biodiesel production. The comprehensive Life Cycle Analysis (LCA) of soybean biodiesel production was conducted by National Renewable Energy Laboratory (NREL) in 1998. Because of increasing changes in land use and production process, the LCA conducted few years ago is no longer representative of current practices.
