Summary: In this study, a solar energy-assisted reactor was developed for biodiesel production from Butea monosperma oil. The optimized conditions resulted in a high yield of Butea monosperma methyl ester (BMME) and the fuel properties of BMME were evaluated. Kinetic studies and thermodynamic analysis were conducted to understand the reaction mechanism and system characteristics. The sustainability indicators for BMME production were also evaluated using green chemistry metrics.

Summary: Five heterogeneous catalysts (Ba(OH)(2), CaO, MgO, ZnO, and AlCl3) were used to produce biodiesel from waste cooking oil. The reaction parameters of each catalyst were optimized by studying the influence of catalyst loading, methanol-to-oil ratio, and reaction duration. The addition of acetone as a cosolvent increased the biodiesel yield, and all heterogeneous catalysts were found to be reusable, with Ba(OH)(2) and CaO showing significant yields until the third cycle.

Summary: Indonesia has become a net importer of oil since 2004 and launched a biodiesel policy in 2006 to mitigate energy challenges. The B30 program implemented in 2020 makes Indonesia the largest implementer of biodiesel in the world. The biodiesel program has significant economic and social impacts, projected to increase the labor force to 10,182 workers by 2030 and save US$4.46 billion in foreign exchange.

Summary: A field experiment was conducted to investigate the effects of biofertilizer and chemical fertilizer on the growth and yield of kasumbha. Results showed that biofertilizer treatment significantly improved plant growth and seed yield, outperforming other treatments. It was concluded that biofertilizer alone could be a sustainable and environmentally friendly alternative to chemical fertilizers in agriculture.

Summary: Biodiesel is an alternative fuel with significant economic, environmental, and social benefits. Conventional biodiesel production is expensive due to high industrial production costs, mainly from raw materials. This research focuses on using magnetic nano-catalysts to produce biodiesel, which have easy recovery, recyclability, selectivity, and fast reaction rates. The nano-catalysts were found to be efficient in transesterifying Pongamia pinnata oil, with high yields achieved after 2 hours of reaction time at 60 degrees C. The synthesized nano-catalysts could be recovered and reused multiple times without losing activity.

Summary: The demand for renewable energy has increased due to the depletion of petroleum oil. Biodiesel, produced from renewable resources with minimal environmental impact, is seen as an alternative to petroleum oil. However, the production and quality of biodiesel are influenced by factors such as physicochemical properties of lipids, selection of feedstock, and technology used for extraction.

Summary: This paper discusses the preparation, characterization, and application of biodiesel (BD) derived from corn oil using a transesterification process. The properties of the prepared corn BD were analyzed using various techniques and compared with fossil diesel. The experimental results show that a blend mixture (BM) containing 25% BD is the most efficient composition among the different blended mixtures of BD, based on diesel engine performance.
