Solvent-aided biomass pretreatment strategies for biorefineries need to address several key points including effective biomass valorization, energy demand, and waste minimization. More specifically, solvents' yield, recovery, and recycling are crucial parameters to improve biorefineries' environmental and economic performances. Gamma-valerolactone (GVL) presents significant promise in biomass pretreatment due to its ability to effectively remove hemicellulose and lignin or provide near-complete biomass solubilization and facilitate hydrolysis. However, GVL utilization is challenging due to its higher cost and the difficulty of recycling it as a high-boiling solvent. Herein, we discuss biomass pretreatment with GVL and solvent recovery. GVL recovery, being conceptual at this stage, has to be proven in the field. It could be realized through liquid−liquid extraction. However, most studies do not address the reutilization of GVL, the separation of heavy-boiling impurities, or the solid−liquid separation of the remaining solids, which are significant gaps in the literature and a limitation to industrialization.

Identifying sustainable chemical processes often depends on the choice of enabling materials that directly influence the overall performance. Matching property targets while incorporating adequate process knowledge is essential for optimal material selection. Multi-scale decisions need to be taken simultaneously to determine the optimal process configurations, operating conditions, and material structures. Integrating molecular to process scale decisions within an equation-oriented optimization framework leads to large-scale mixed-integer nonlinear programs (MINLP). Over the years, several solution approaches have been suggested to tackle this issue. Here, the current state-of-the-art in the field of computer-aided molecular and process design (CAMPD) is discussed and key challenges and open questions are highlighted that may stimulate future research.

Optimally designed solvent system for lignocellulosic biomass conversion supported by property predictions

Abstract: A computational screening combined with experimental biomass conversion shows that GVL-based hydrolysis can be designed to optimality and the conventionally selected co-solvent toluene would result in higher process operating costs than ethylbenzene.
