Review of Lignocellulosic Biomass Pretreatment Using Physical, Thermal and Chemical Methods for Higher Yields in Bioethanol Production

Sustainability, Journal Year: 2025, Volume and Issue: 17(1), P. 287 - 287

Published: Jan. 2, 2025

The increasing demand for renewable energy sources has led to significant interest in second-generation biofuels derived from lignocellulosic biomass and waste materials. This review underscores the pivotal role of valorization meeting global needs, mitigating greenhouse gas emissions, fostering a circular bioeconomy. Key pretreatment methods—including steam explosion, pressure treatment, chemical pretreatment—are analyzed their ability enhance accessibility cellulose hemicellulose enzymatic saccharification. Advances cellulolytic enzyme development fermentation strategies, such as use genetically engineered microorganisms capable fermenting both hexoses pentoses, are discussed detail. Furthermore, potential biorefinery systems is explored, highlighting capacity integrate into biofuel production alongside high-value bioproducts. Case studies recent trends bioethanol biogas examined, providing insights current state research its industrial applications. While hold considerable promise sustainable emissions reduction, challenges related cost optimization, process scalability, technological barriers must be addressed enable large-scale implementation. serves comprehensive foundation bridging gap between laboratory application, emphasizing need continued innovation interdisciplinary collaboration technologies.

Pineapple (Ananas comosus) is one of the most economically important fruit cultivars in South Africa. The locally consumed, processed into various industrial products or exported to foreign markets. Approximately 115,106 metric tons pineapple are harvested value chain generates significant amounts waste, form pomace, peel, crown, stem, core and base. If not properly treated, waste (PAW) could have a profound detrimental impact on environment. This calls for advanced technological platforms transform PAW useful bio-based products. A biorefinery potent strategy convert multiple food non-food while effectively disposing waste. objective this review explore possible pathways valorization energy material biorefinery. paper looks at 10 including biogas, biohythane, bioethanol, biobutanol, biohydrogen, pyrolytic products, single-cell proteins, animal feed, vermicompost bioactive compounds. Several (i.e., biochemical, chemical, physical thermochemical) available valuable goods. Amongst them, biochemical route appears be favorable option PAW. Anaerobic digestion fermentation well-established technologies valorization. These methods simple, low-cost, eco-friendly sustainable. focal point emerging research enhanced efficacy platforms. commercialization biorefining potential gamechanger that revitalize entire African economy.

Harnessing Fruit and Vegetable Waste for Biofuel Production: Advances and Scope for Future Development

eFood, Journal Year: 2025, Volume and Issue: 6(2)

Published: April 1, 2025

ABSTRACT Extreme exploitation of petroleum fuels has raised concerns around global warming due to increased greenhouse gas emissions, which by the year 2040 are expected rise 43 billion metric tons. Biofuels have gained popularity in recent years because their renewable and environmentally friendly prospects. Second‐generation biodiesel is generated from nonedible raw materials such as food waste, suggested lesser negative impacts on environment does not threaten security. Edible fruit waste (7.65 kg/person) edible vegetable (16 highest contribution 38% waste. Annually, this corresponds 15.78 m 2 cropland usage, 1.358 kg CO equivalent, 232.87 g nitrogen 3810.6 L freshwater 38.544 phosphorus usage per person for agricultural production. FVW includes peels, seeds, crops, leaves, straw, stems, roots, or tubers. This can be utilized feedstock biofuel instead burning, dumping, landfilling, leads economic, environmental, health issues water‐borne diseases, respiratory lung diseases. Converting lignocellulosic mass into green energy including biogas, bioethanol, biohydrogen help management while also contributing carbon‐neutral model. Past studies shown potential using generation, jet fuels, general diesel engines. review focuses latest advances production technology, with an emphasis new pretreatments, technologies, works improve biomass.
