Abstract: With the growing global population, biomass generation is also rising, and to achieve the goals of sustainable development and circular economy, converting biomass into renewable energy products is crucial. Recent advancements in biochemical and thermochemical processes maximize biofuel and bioenergy output and efficiency. Advanced pretreatment methods improve cellulose and hemicellulose accessibility, enhancing the overall conversion efficiency of biomass into biofuels & useful bio-products. Further, innovations in bioreactor design, biocatalysts, nanotechnology, ‘omics-technologies,’ and database systems have boosted biofuel and bioenergy production. However, integration of different renewable energies like solar, wind, and hydro energy technologies in combination with bioenergy for hybrid systems further confers maximizes energy output through a 15–37 % decrease in total system cost and minimizes waste of resources. It also contributing to achieve climate goals and energy security accompanied with an eminent 12–30 % decrease in greenhouse gas emission. The advantages, limitations and future directions of cutting-edge biomass conversions technologies and their integration with artificial intelligence and hybrid systems discussed in this review article to reduce waste, promote sustainable development, aligning with circular economy framework and sustainability goals for a clean and green future.
