Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Valorization of fishing industry by‐products for biodiesel production: Unlocking the potential of residual fish oil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fishing waste and its by‐products, whether naturally occurring or generated by the processing industry, represent a significant opportunity for producing high‐value products. These often discarded or underutilized residues can be converted into various valuable products through advanced processing technologies. Among the potential products are

Lab‐Scale Continuous Biomanufacturing: A Tool for Process Development With Adaptive Strategies for Capture and Virus Inactivation

Biotechnology and Bioengineering, EarlyView.
Schematic representation of the continuous lab‐scale process. ABSTRACT Monoclonal antibodies (mAbs) are nowadays fundamental in treating a wide range of severe diseases, including cancer, infections, or autoimmune disorders. Due to their high specificity, potent activity, and fewer side effects compared to small molecular drugs, the market for mAbs is ...

Selective Synthesis of N,N‐Dimethylformamide From CO2 Hydrogenation Coupled With Dimethylamine Over a ZnZrOx Solid‐Solution Catalyst

Carbon and Hydrogen, EarlyView.
N‐formylation of dimethylamine though CO2 hydrogenation takes place at a ZnZrOx solid‐solution catalyst surface toward N,N‐dimethylformamide. By synergistic effect of Zn and Zr sites, the catalyst achieves 99% DMF selectivity at 14% DMA conversion at 280°C with at least 1000 h stability on steam.
