An amazing finding in second generation bioethanol from perennial grasses has shown a promising result. Scientists at the USDA might have found a way to keep switchgrass forever young and better for cellulosic ethanol.
Several experiences have been providing evidences on the feasibility of marginal lands bioenergy. We selected promising alternatives for biofuels, heat and electricity in semiarid environments, abandoned lands and low competitive regions.
We received news from REUTER on a publication from Lancaster University researchers about biofuels modeling sustainability and environmental impacts to the air. We revised it and made some comments on the credibility of the conclusions.
The World Bioenergy Association, has published a new fact sheet on forest sustainability and carbon neutrality. The report from the World Bioenergy Association, emphasizes the fact that carbon debt and payback theories are based on unrealistic assumptions and that biomass is carbon neutral.
