It is no longer unfamiliar to the world that usage of fossil-derived fuel accompanied by several downsides, including environmental fatality associated with toxic gas emissions from diesel engines and recurring surging price fuel. The concern regarding exploitation natural resources subsequent threats has caught attention all nations. Therefore, scientists have stepped forward come up most suitable alternative conventional They utilized abundance oil feedstocks performed transesterification reactions short-chain alcohols produce less toxic, eco-friendly termed Biodiesel which was considered be a viable substitute. In order carry out reaction feasibly, certain homogeneous heterogeneous catalysts were employed. Heterogeneous got more recognition among researchers; however, many these did not attain large-scale production. Among catalysts, calcium oxide (CaO) appeared one solid base for biodiesel synthesis. CaO can derived chemically as well sources such chicken eggshells, snail shells, biont shells more. exhibits high catalytic activity perform reactions. Additionally, cheap catalyst also used support material various systems. Constructing effective CaO-based industrial production unlocks scope process advancements in this area. This paper aims review performances recently reported solid-base systems biodiesel. Moreover, preparation conditions, parameters, properties obtained, advantages disadvantages, life cycle assessment, circular economy discussed.

Abstract Microalgal feedstock is a potential source for biodiesel production that addresses the challenges of fuel security and sustainable agriculture. This study aims to maximize biomass yield lipid accumulation freshwater microalga Monoraphidium sp. NCIM 5585 utilize it production, contributing development biocatalysis-based biofuels. Independent optimization studies were conducted investigate critical growth parameters, viz., light intensity, photoperiod, NaNO 3 concentration. The showed highest productivity 51.75 ± 1.9 mg/L.d content 47.3 0.02% (w/w) at 40 µmol/m 2 /s 16 h L:08 D 0.25 g/L . Further, novel CaO bionanocatalyst was synthesized using residual microalgal characterized SEM, EDX, FT-IR, XRD. characterization results from SEM EDX confirmed structural elemental composition with Ca O as main elements. XRD revealed crystalline nature particle size 17.83 nm. 86.5 0.65% FAME obtained catalyst 1 H NMR, 13 C NMR GC-MS. demonstrates sp., optimized conditions significance reusability offering promising solution biotechnology applications.
