Analysis of the routes for biomass processing towards sustainable development in the conceptual design step: Strategy based on the compendium of bioprocesses portfolio

Process sustainability has been one of the most challenging issues faced by process designers. Conceptual designed processes do not overcome this stage because aspects such as context and technological readiness level are left aside. This paper proposes a strategy to consider different processing routes for biomass (compendium of existing routes) towards sustainable development. The strategy comprises five stages where a supported bio-processes selection is made by considering the chemical composition of the raw material and the context where biomass is produced and processed. This strategy aims to give decision tools to designers to filter and reduce the number of options to be considered when proposing an alternative biomass use. The proposed strategy was applied to upgrade orange peel waste and sugarcane bagasse to demonstrate how it can be applied. In conclusion, selecting of bioprocesses and considering the proposed strategycould improve the biorefineries design. Even so, more bioprocesses must be included.
