Perennial energy crops and biodiversity could be benefitial for fauna in metal contaminated soils, said a very recent article published in Biomass and Bioenergy Journal (Feb 2014).
Energy crops pellets are technically feasible . A lot of progress by companies developing technology and recent research produce densification in biomass from herbaceous crops or by mixing herbaceous and woody biomass.
A brand new study (2013) found that the projected energy demand (2035) in developing countries, can be covered with energy crops in surplus agricultural lands, then not competing with food production.
From food debate and land use changes effects to biofuels sustainability, a lot of scientific findings show great differences among alternatives. We joined best scientific information.
A very recent research publication found harvested area with food crops to be increasing during 2000-2010 period simultaneously with biofuel expansion.
A broader mix of bioenergy crops to reduce environmental impacts is suggested in last report issued by the European Environment Agency.
Bioenergy crops in marginal lands have been always a focus of attention for researchers, bioenergy companies and governments. But those areas would clearly have lower yields. Are lower cost feasible in those regions?.
Lignocellulosic crops have shown in recent decades a more efficient pathway to produce energy and also lower environmental impacts. Life cycle assessments show that fertilizers efficiency is critical as well as expected yields and extractions levels when producing energy crops. We discuss implications and criteria to apply.
A semiarid country like Spain, often have very low grain yields and per hectare income from winter cereals. Since a 16MW straw based power plant in Bivriesca, Burgos, started 200.000 tons/yr and 12M € have been part of the local economy.
Recent trends of bioenergy, lignocellulosic raw materials and grasslands for advanced biofuels, biopower, pulp and biogas show promising perspectives in 2013.
