Summary: This article explores the potential of Phoenix sylvestris oil as a viable feedstock for biodiesel extraction. Through catalytic esterification, the free fatty acid is transformed into esters before proceeding to alkaline catalytic esterification. The biodiesel produced from Phoenix sylvestris oil has similar characteristics to standard biodiesel and shows better performance than neat oil and its blends.

Summary: This study focuses on the distribution and characterization of microplastics in sediments and their transfer into living organisms in the backwaters of Kavvayi and Kumbla regions in Kerala, India. Microplastics were detected in all samples, with an average abundance of 99.5 +/- 69.43 particles/kg and 96.57 +/- 29.96 particles/kg in Kavvayi and Kumbla backwaters, respectively. Raman spectral analysis confirmed the composition of the microplastics, with synthetic elastomers comprising nearly 50% of the particles. The higher abundance of microplastics in edible aquatic organisms highlights the need for further investigation into their toxicological impacts and management strategies.

Summary: Household access to clean energy is essential for public health and environmental preservation in low- and middle-income countries. This study proposes a hierarchy of reduction potentials for household energy emissions, taking into account various implementation barriers such as distributional, technical, economic, and market factors. By applying this framework to India, the researchers found that implementing reduction programs within a certain distance from urban centers can achieve a significant portion of the theoretical reduction potential. Additionally, the study emphasizes the importance of considering the factors that affect transitions to clean energy solutions rather than solely quantifying baseline emissions in emission inventory development.

Summary: This paper presents a study on optimizing biodiesel blends produced from waste cooking oil for use in urban medium-duty commercial vehicles in India. An artificial neural network model is used to predict performance, combustion, and emission parameters, and a multi-objective optimization is carried out to determine the optimal blend concentration based on different criteria. Considerations for blend concentration selection are discussed in relation to governmental targets.

Summary: This study suggests that foreign direct investment can have different impacts on a country's environment, especially for countries in central positions in the global FDI network and those with more internal FDI. The results show that countries with higher inward FDI and FDI network centrality have higher carbon dioxide emissions, particularly in Global South countries. This indicates that foreign investment may lead to the outsourcing of environmentally harmful production processes and have negative environmental impacts.

Summary: This study investigates the photochemical evolution of air in the downwind of a semi-arid urban environment in India and finds large ozone production, simulated levels of secondary inorganics and organics, and high levels of hydroxyl and hydroperoxyl radicals. Air mass trajectory analysis suggests the outflow of ozone-rich air over rural areas and the Arabian Sea, highlighting the impact of urban outflows on regional atmospheric composition.

Summary: The present study compares the performance and emission characteristics of a multicylinder engine fueled with MZME, KME, and neat diesel. The experimental results show that the biodiesel blends have higher fuel consumption and lower brake power compared to diesel. However, under certain conditions, the blended fuels have lower CO and HC emissions but higher NOx emissions.

Summary: The present study conducted experimental investigations to optimize engine operating parameters for superior performance and reduced emissions in a single cylinder diesel engine powered by Bauhinia variegata methyl ester (BVME). The study investigated various responses such as brake thermal efficiency, brake specific fuel consumption, carbon monoxide, hydrocarbons, and nitrogen oxides by varying engine load, injection pressure, and compression ratio. A hybrid approach was developed to optimize the input parameters, resulting in improved performance at optimal parameters. The results demonstrated that using the B20 blend of BVME with diesel fuel operation achieved significant improvements in various performance parameters compared to diesel fuel.
