Abstract The application of nanocatalysts for the conversion crude oil into biodiesel represents a promising strategy to mitigate environmental issues and diminish dependence on fossil fuels. This review scrutinizes contemporary developments in nanocatalyst technology pertaining synthesis, emphasizing effectiveness, specificity, ecological sustainability various nanocatalysts, which include metal oxides, magnetic solid catalysts, an array other nanostructured materials. These catalysts have exhibited substantial potential augmenting efficiency selectivity production, attributable their enhanced catalytic performance, extensive surface area, resilience saponification, rendering them appropriate diverse feedstocks such as recycled oils, animal fats, plant oils. Notwithstanding obstacles associated with production costs recycling procedures, recent progress economically viable manufacturing techniques sustainable recovery methods, including separation approaches, offers significant promise. A thorough lifecycle assessment (LCA) remains imperative appraise economic viability employing taking account parameters, raw material acquisition, energy utilization, waste generation. accentuates superior efficacy comparison traditional heterogeneous underscoring capacity expedite synthesis facilitate transition toward more environmentally paradigm.

The wastewater generated from diverse human activities needs to be treated, restore, and reused. Researchers have moved the deployment of synthetic absorbents manufacturing adsorbents waste biomass for elimination contaminants wastewater. biochar constructed agricultural has elicited significant devotion due its ready availability, accessibility, low cost, ease preparation, environmental sustainability. This review presents developments in utilization obtained remediation domestic wastewater, industrial stormwater. Discussions on classification, composition, characteristics waste, techniques production, as well outcomes decontamination were highlighted. study concludes that, notwithstanding identified environmental, social, economic, infrastructural challenges, is an effective, efficient, easy use, eco-friendly adsorbent Agricultural waste-derived removes safeguards aquatic ecosystem contributes availability safe water. Future research directions innovative more effective avenues application developed treatment are suggested. outcome this will stimulate renewed interests using readily available materials remediation.

This research investigated the usefulness of magnetic iron oxide nanoparticles (Fe3O4) as a support to immobilize lipase Eversa Transform 2.0 (ET 2.0) obtain an active and stable biocatalyst, easily recoverable from reaction medium for applications in production biodiesel. Biodiesel was alternative fuel composed mainly fatty acid esters with strong transesterification esterification capabilities. The study focused on oleic ethanol synthesize ethyl oleate. Magnetic were prepared by coprecipitation, then activated glutaraldehyde functionalized γ-aminopropyltriethoxysilane (APTES). optimal conditions immobilizing ET pH 10, 25 mM sodium carbonate buffer, enzymatic load 200 U/g, 1 h contact time, obtaining 78% yield activity 205.9 U/g. Postimmobilization evaluation showed that immobilized enzyme performed better than its free form. Kinetic studies conducted under these optimized (2–96 at 150 rpm 37 °C). biocatalyst tested synthesis oleate using substrate ethanol, achieving conversion 88.1%. Subsequent recirculation tests maintained approximately 80% until fourth cycle, confirming sustainability ester production. Molecular docking revealed binding affinity enzyme-docked oil composition estimated −5.8 kcal/mol, suggesting combination suitable esterification.

Abstract This study aimed to enhance the economic viability and sustainability of cotton industry by converting cottonseed into energy. Cottonseed was subjected lipid extraction for biodiesel production, a pyrolysis test conducted under N 2 CO conditions valorise defatted cottonseed. Under conditions, increase in concentration due homogeneous reaction with volatile matters. Biochar, pyrolytic product cottonseed, used as catalyst thermally induced transesterification, showed high performance conversion efficiency its abundant alkaline earth metals meso-/macro-pores. For example, transesterification using silica at 250 ˚C yielded only 1.6 wt.% biodiesel, whereas biochar same temperature resulted significantly higher yield 83.5 wt.%. experimentally proved that 7,900 tons (304 million MJ) could be produced annually, surpassing diesel fuel requirement (145 cultivation. These results indicate potential fully replace fossil fuels industry. Graphical
