Biofuel Research Journal (BRJ) is a leading, peer-reviewed academic journal dedicated to publishing high-quality research on biofuels, bioproducts, and related biomass-derived materials and technologies. BRJ is an open-access online journal and completely free-of-charge, aiming to advance knowledge and understanding of sustainable energy solutions, environmental protection, and the circular economy through cutting-edge research and innovative applications. Biofuels and Bioproducts: Exploring the production, characterization, and application of various biofuels, such as biodiesel, bioalcohols (bioethanol, biobutanol), biogas (biomethane, biohydrogen), algal biofuels, and other emerging biofuel sources. Additionally, BRJ encourages research on bioproducts, including biocomposites, bio-based smart materials, and innovative applications in the fields of food, pharmaceuticals, and beyond. Biomass Valorization: Investigating efficient and sustainable methods for biomass conversion, including biorefineries, bioprocesses, and advanced biomass utilization techniques to maximize energy and value-added product yields. Biomass-Derived Materials for Energy and Storage Systems: Advancing research on biomass-derived materials with potential applications in energy conversion and storage systems, including fuel cells, batteries, supercapacitors, and photovoltaic modules.
