Environmental performance of crop residues as an energy source for electricity production: The case of wheat straw in Denmark

► This paper assesses the environmental performance of wheat straw as an energy source. ► Coal and natural gas (NG) are selected as references for comparison with straw. ► Straw has a better performance than coal and NG in some midpoint impact categories. ► The single score results show that straw is better than coal but worse than NG. ► Potential improvements lie in reducing NOx emissions and increasing power output.
