Abstract
Organic waste and residue streams are ever increasingly seen as abundant and low-cost resources with great economic and environmental potential. Most of it comes from agriculture, forestry, biobased industry, and forestry. However, comparatively low quality, high cost of logistics and variability in availability and composition are still an obstacle to much greater utilization of these types of biomasses. This chapter is an approach to systemize knowledge about organic residue and waste streams to better promote them as feedstock.
