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.

Waste cooking oils (WCOs) are generated globally from households, the hospitality industry, and other sectors. Presently, WCOs mainly employed as feedstock for biodiesel energy production, strongly depending on availability of WCOs, which often imported countries. The objective this review is to give an overall comprehensive panorama impacts, regulations, restrictions affecting their possible uses producing high-value products, such bio lubricants, surfactants, polymer additives, road construction solvents. Interestingly, many reviews reported in literature that address use but a topic missing. Published studies, industry reports, regulatory documents were examined identify trends, challenges, production statistics, environmental current production. data collected show hold immense potential renewable resources sustainable industrial applications line with global carbon neutrality goals circular economy principles. However, achieving shift requires addressing gaps, enhancing collection systems, optimizing conversion technologies. This underlines need collaborative efforts among policymakers, stakeholders, researchers maximize contribute development.

Waste cooking oils (WCOs) are generated globally in significant amounts by various sectors including hospitality, households, and industrial operations. Many nations currently lack dedicated legislation for managing WCOs, creating a pressing environmental challenge. At present, WCOs primarily utilized industries as raw materials biodiesel production energy generation. However, their role second-generation is contingent on availability, often necessitating imports of either or from other countries. The European Union has emphasized the importance prioritizing biowaste high-value alternative products beyond to achieve carbon neutrality 2050. reviews have been published literature reporting potential WCO applications produce biolubricants, biosolvents, animal feed, asphalt additives, among others, however, no detailed analysis trends ever presented. Within this panorama, unlike existing that focus specific polymer classes derived work sought present comprehensive overview use polymeric fuel energy, providing general patents (or alive) last 10 years, together with which innovative being introduced sold market today.

Biodiesel is mainly produced from various bio-based sources, including vegetable oils, waste cooking oil, and more, by esterification transesterification processes using a suitable catalyst – preferably heterogeneous as it more beneficial in terms of reusability, recovery, product purity, production cost. Different feedstocks are used for the biodiesel, with oil emerging promising feedstock. offers several advantages, reduced viscosity, higher flash point, elevated cetane number, biodegradability, non-toxicity, lower greenhouse gas emissions. Additionally, exhibits shorter ignition times greater combustion efficiency, making favorable prolonging engine lifespan. However, concerns regarding use biodiesel have primarily revolved around its quality potential long-term impacts on diesel vehicles. Therefore, chemical modification methods been explored to address this issue, being most commonly utilized approaches. This review comprehensively examines current state knowledge recent advancements synthesizes findings wide range research articles, focusing key aspects such feedstock selection, conversion technologies, environmental economic viability toward circular economy Ghana.
