Nitrogen fertilizers are responsible of most biofuels sustainability limitations in life cycle assessments and carbon footprint. But some very realistic strategies and new findings would help to reduce their impacts.
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.
The European Union assembly fixed a 6 percent limit on the use of crop-based biofuels in ground transport, seeking to spur the development of clean fuels from non-food sources.
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.
Biobased industries invest millions on feedstock and supply chains with energy crops. Find 10 ways to save millions on energy crops asking for independent advice and avoid huge risks.
Small plots and research scales are not as realistic as productivity from field plots when making economic assumptions in any project.
Miscanthus among perennial bioenergy crops in northern EU, has been promoted during last decade for heat and power production. After cultivating more than 12,000 hectares in UK, too low average yields (10-12 odt/ha per year) and high costs of delivered biomass (60-140 €/odt) are becoming major constraints
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?.
