Due to changes in carbon stock of soil and biomass, indirect land-use change (ILUC) has consequences on green house gas (GHG) balance of a biofuel that are not presently considered in evaluation of environmental merits of biofuels. Significant changes in l ...

The promotion of biofuels as energy for transportation in the industrialized countries is mainly driven by the perspective of oil depletion, the concerns about energy security and global warming. However due to sustainability constraints, biofuels will rep ...
Biodiesel, a mixture of fatty acid methyl esters (FAMEs) derived from animal fats or vegetable oils, is rapidly moving towards the mainstream as an alternative source of energy. However, the behavior of biodiesel, or blends of biodiesel with fossil diesel, ...
Blends of biodiesel and petrodiesel are being used increasingly worldwide. Due to several factors, inaccurate blending of these two mixtures can occur. To test the accuracy of biodiesel blending, we developed and validated a radiocarbon-based method and th ...
Background, aim and scope. Regional specificities are a key factor when analyzing the environmental impact of a biofuel pathway through a life cycle assessment (LCA). Due to different energy mixes, transport distances, agricultural practices and land use c ...
There has been growing concern about the way cultivating biomass for the production of agro-biofuels competes with food production. To avoid this competition biomass production for biofuels will, in the long term, have to be completely decoupled from food ...
The acyl transfer of phenylalanine to MeOH by means of chymotrypsin starting from phenylalanine Pr ester has been studied. This transesterification turns out to be useful for producing optically pure phenylalanine esters as well as for the optical resoln. ...
