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) 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. Life cycle fossil energy ratio of Chlorella vulgaris based biodiesel is improved by För att göra biodiesel i vårt exempel krävs raps, metanol (20 procents inblandning) och kaliumhydroxid. Baserat på ett rapspris på 3,40 kr och ett metanolpris på 7 kr/l. Kostnaden för arbete, investeringar i utrustning och el är inte inräknad. Det behövs 3 liter raps och 2 dl metanol för att göra en liter biodiesel. The energy ratio was 2.70 for the rapeseed biodiesel production chain. The specific energy and the energy productivity for rapeseed biodiesel production were calculated as 24.41 MJ/kg and 0.0409 kg/MJ, respectively.

Nanaki and Koroneos used life-cycle analysis (LCA) to compare biodiesel, diesel and gasoline for transportation purposes, and found that biodiesel seems to have the greatest potential to reduce

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.

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. 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.
