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 ...

Process development priorities for scaling up direct microbial conversion of sugars into value‐added biochemicals

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The study identified process development priorities toward the feasible production of five value‐added biochemicals in a sugarcane biorefinery based on achievable bioconversion performances. Multiple process scenarios using A‐molasses as feedstock were simulated in Aspen Plus® via direct microbial conversions.

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

Integrated bioconversion of starchy and hemicellulosic fractions of macauba oil presscake into ethanol by nonconventional yeasts

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Co‐fermentation of hexoses and pentoses from plant biomass to ethanol is a strategy to increase ethanol production from lignocellulosic materials and add value to residues from agroindustrial chains. The macauba (Acrocomia aculeata) is an oleaginous palm‐tree species considered to contribute to development in some regions of Brazil.

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

Valorization of paper sludge for bioethanol and biogas production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study evaluated the physicochemical properties and bioenergy potential of three distinct paper sludges: virgin pulp sludge (VP‐PS), corrugated cardboard sludge (CR‐PS), and tissue and printing paper sludge (TPR‐PS). From the experimental runs, VP‐PS exhibited the highest ethanol yield (46.8 ± 3.7 g L−1, 87.4% conversion), which can be ...
