Environmental life cycle assessment of producing willow, alfalfa and straw from spring barley as feedstocks for bioenergy or biorefinery systems 


A new paper in SeSE platform has recently been published in Science of the Total Environment, Volume 586.

The article is a collaboration between Department of Agroecology, Aarhus University and Department of Management Engineering, Technical University of Denmark. The study aimed at evaluating potential environmental impacts for the production of willow, alfalfa and straw from spring barley as feedstocks for bioenergy or biorefinery systems, by using a method of Life Cycle Assessment. The results obtained per ton dry matter showed a lower carbon footprint for willow and alfalfa compared to straw. Also, based on the energy output to input ratio, willow performed better than other biomasses. However, the environmental impacts of the biochemical conversions of the biomasses (e.g. in sugar based platform) would be differing based on the conversion efficiency of the refinery process and the biomasses’ variable carbohydrate content.
