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.

India’s rapidly growing automobile industry has intensified the need for sustainable fuel alternatives to reduce dependency on imported fossil fuels and mitigate greenhouse gas (GHG) emissions. This study examines potential of second-generation biorefineries as a comprehensive solution efficient biomass valorization in India. With projected bioethanol demand 10,160 million liters by 2025 20% ethanol blending target, there is an urgent develop production pathways. The biorefinery approach enables simultaneous multiple valuable products, including bioethanol, biochemicals, bioproducts, from same feedstock, thereby enhancing economic viability through additional revenue streams while minimizing waste. paper systematically analyzes available resources across India, evaluates integrated conversion technologies (biochemical, thermochemical, synergistic approaches), current policy frameworks supporting implementation. Our findings reveal that can significantly contribute reducing GHG emissions up 2.7% gross domestic product (GDP) 2030 creating rural employment opportunities strengthening energy security. However, challenges supply chain logistics, technological optimization, harmonization continue hinder large-scale commercialization. concludes proposing strategic interventions overcome these barriers accelerate transition toward circular bioeconomy

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.

Life cycle assessment (LCA) was conducted to evaluate the environmental impacts and health risks associated with four thermochemical conversion technologies: incineration, gasification, pyrolytic liquefaction, hydrothermal liquefaction. Results revealed that all processes yielded positive net benefits (3.8–8.2 kg CO2-eq/kg AR reduction), liquefaction exhibiting lowest emissions (GWP-5.71 CO2-eq/kg). However, its widespread application has been hindered by process limitations, enhancing catalytic efficiency identified as a critical area for future research. Incineration ranked second in terms of remains most favorable method according existing studies. In contrast, gasification did not demonstrate significant advantages, primarily due high energy consumption required drying. Consequently, optimizing drying highlighted key focus research efforts. This study provided valuable insights safe disposal resource recovery antibiotic residue.
