Sustainable energy crops for biogas

The sustainable use of  energy crops for biogas is a possible solution to reduce the contribution to climate change of human activities. Power based on biomass, in particular biogas, is increasing, with a concomitant increase in the need for energy crop production.

Sustainable bioenergy and grasslands on the edge

There is an increasing interest worldwide on developing sustainable bioenergy alternatives for low competitive lands where food production profitability is scarce or where soils and climates  are not suited for traditional activities or have no market access and low competitiveness.

“Staygreen” gen for switchgrass?: A genetic breeding to improve ethanol yields as energy crop

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. 

WBA: “Carbon debt and ‘payback time’ of biomass are not credible”

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. 

Cut management and Harvest period of Switchgrass

The harvest period for lignocellulosic crop is a crucial aspect to be taken into account when we analyze the possibility to use this crop in relation with energy conversion system.

Biomass logistic: Harvest systems and analysis for herbaceous Biomass

Biomass feedstocks including crop residues and energy crops hold great potential for energy source. They are currently being considered for use in direct combustion systems and for value added byproducts such as biofuels or biocrude.
