Sewage sludge was treated with nanoscale zero-valent iron (nZVI) to enhance biogas and methane (CH4) production, the influence of key parameters on material’s anaerobic digestion (AD) efficiency analyzed using sigmoidal mathematical models. In this study, three dosages nZVI (0.5%, 1.5% 3%) were added system accelerate decomposition process. The results showed that cumulative yield after 41 days increased by 23.9% in reactor a dosage 1.5%. Correspondingly, highest CH4 production enhancement 21.5% achieved compared control. indicated optimal for AD system, as it governed yields maximum removal total volatile solids. Additionally, predict evaluate kinetic parameters, eight models applied. According modified Gompertz, Richards logistic models, shortened lag phase from 11 5 Schnute model provided best fit experimental data due coefficients determination (R2: 0.9997–0.9999 at 3% dosages), well lowest Akaike’s Information Criterion values errors. This demonstrated its superior performance other

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
