Isolation of Lignin from Anaerobically Digested Unhydrolyzed Solids Produced in a Biorefinery
Agriculture, 2022 About 30–40% of lignin-rich unhydrolyzed solids (UHS) are left behind after subjecting lignocellulosic biomass to thermochemical pretreated processes followed by enzymatic hydrolysis (EH) to produce sugars that are fermented to fuels and chemicals in a ...

The Waste-to-Biomethane Logistic Problem: A mathematical optimization approach [PDF]
arXiv, 2023 In this paper, we propose a new mathematical optimization approach to make decisions on the optimal design of a logistic system to produce biogas from waste. We provide an integrated model that allows decision makers to optimally determine the locations of different types of plants and pipelines involved in the logistic process, as well as the most ...
