Production and use of lignocellulosic bioethanol in Europe: Current situation and perspectives

Edgard Gnansounou

Contrary to the case of the United States where a systematic management of the RD&D on lignocellulosic ethanol prevails, in Europe the research works remain fragmented despite the efforts made by the European Union and in few member states. In most of the ...

Estimating greenhouse gas emissions from indirect land-use change in biofuels production: concepts and exploratory analysis for soybean-based biodiesel production

Edgard Gnansounou, Luis Alberto Panichelli

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 ...
