Integrated sustainability assessment of an innovative lignocellulose biorefinery concept based on the acetone organosolv process

2.2.1 Goal The goal of this work is to assess the sustainability of the UNRAVEL value chains in a streamlined and comprehensive manner, covering the main aspects of sustainability: environment, economy and society. [...] It is the goal of the final report at the end of the project to answer these questions. [...] The scope should be sufficiently well defined to ensure that the comprehensiveness, depth and detail of the study are compatible and sufficient to address the stated goal. [...] The solvent rich overhead vapour of the falling film evaporator is sent to a distillation where part of the water and the small amounts of furfural are removed. [...] For the other biomass feedstocks, it is not the price of the biomass (which is only a bit higher for wheat straw) which lead to an increase in the needed green premium, but in the higher costs for amount of feedstocks and other inputs and the lower amount of high value products (like modified lignin or hydrophobic lignin) at the same level of (dry) biomass input.
