Willow as a biomass crop

Short rotation willow coppice is a perennial agricultural crop, grown for production of woody biomass. Willow is established by using stem-cuttings, about 20 cm long, planted by different types of machines. The crop is planted once and then harvested in a number of cycles without replanting. New shoots will emerge after harvest from the cut stumps.

The harvest is usually done by direct chipping combiners, where the chips are loaded directly on waggons/containers for delivery to adjacent boiler. Other types of harvesting systems are under development, like systems for baling or bundling of whole shoots
