Abstract The excessive reliance on fossil fuels has resulted in an energy crisis, environmental pollution, and health problems, calling for alternative such as biodiesel. Here, we review computational chemistry machine learning optimizing biodiesel production from waste. This article presents techniques, characteristics, transesterification, waste materials, policies encouraging Computational techniques are applied to catalyst design deactivation, reaction reactor optimization, stability assessment, feedstock analysis, process scale-up, mechanims, molecular dynamics simulation. Waste comprise cooking oil, animal fat, vegetable algae, fish waste, municipal solid sewage sludge. oil represents about 10% of global production, restaurants alone produce over 1,000,000 m 3 annual. Microalgae produces 250 times more per acre than soybeans 7–31 palm oil. Transesterification food lipids can with a 100% yield. Sewage sludge significant biomass that contribute renewable production.

The incorporation of biomass waste into the process wealth creation through production hydrogen, a significant fuel source for renewable energy. Hydrogen from various sources, including crop remnants, algae, or waste, makes use easily accessible and materials, ensuring an uninterrupted supply without exhausting fossil reserves. Traditional techniques, like gasification pyrolysis, used hydrogen residues, present notable challenges such as high temperature pressure demands, substantial capital investment, risk releasing pollutants. Conversely, innovative approach photoelectrocatalytic green stands at vanguard clean energy advancements, holding great promise directly deriving with help sunlight, offering genuinely sustainable eco-friendly resolution. integration sunlight extra electrical stimulus biomass-to-hydrogen conversion, leveraging resources that are abundantly available continuously renewed, endorses truly nature this process. resultant fuel, created method, burns cleanly, emitting solely water vapor thus significantly curbing greenhouse gas emissions air pollution. This exhaustive review presents detailed evaluation utilization diverse raw covering carbohydrates, lignin, triglycerides (fats oils), proteins, terpenes production. It highlights transformative possibilities arising synergistic amalgamation electrocatalytic (EC) photocatalytic (PC) technologies, setting new pioneering era transition towards effective circular economy.

Biogas is a resource of renewable energy with the highest significance to development in many countries due great accessibility biomass. It mostly produced by anaerobic digestion various feedstocks, but technologies such as landfilling, aerobic composting and incineration are also being used. The current novel review aimed present emerging for biogas pretreatment, production upgrading process. Furthermore, applications future perspectives have been covered. was found that pretreatment chemical, physical, thermochemical oxidative increasing biomethane yield. Hence, extrusion has increased 190%. upgrading, photosynthetic biofixation CO2 microalgae shown upgraded CH4 maximum content ranging from 2 6%. Microbial electrolysis cell technology sustainable effective low requirement energy. Thus, it bioelectromethanogenesis leads uptake 13.2 gCO2/d. In addition, nanobubble recent studies extensively investigated improvement methane Europe around 70% plants utilising feedstocks agriculture sectors. 2022 global combined reached more than 1.6 EJ which an increase 17% last five years. Fossil fuels primary source 85% world's supply. wider use could ensure goals implementation
