Mobilizing mine lands for biobased decarbonization strategies
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Over 163 000 ha of mine lands in Pennsylvania (PA) have the potential to produce willow as a feedstock for renewable energy generation. Each year these lands could produce between 454 000 and 907 000 dry Mg of willow, which can be a feedstock for bioenergy (i.e., biopower) with carbon capture and sequestration (BECCS) or sustainable aviation ...
