Abstract
The burning of excessive fossil fuel produces a high amount of noxious compounds, posing significant threats to environmental and human health. However, to elucidate these problems in this study biodiesel was produced from the locally available dropdown neem (Melia azadirachta) seeds derived oil by applying the widely practiced transesterification process via solution blending with high yield (around 86%). Using advanced instruments (such as GC, FTIR-ATR, CV analysis, etc.), the produced biodiesel was characterized and it's overall qualities were investigated by optimizing it under different conditions, such as catalyst, temperature, time and stirring speed. The observed results showed biodiesels have possessed high calorific values (around 9562.22 ± 5.87 kcal/kg), remarkable physicochemical properties, active binding sites along with various saturated/unsaturated fatty acids. Therefore, due to these exceptional properties, the newly produced biodiesels would be beneficially used in various sectors as a suitable replacement of hazardous fossil fuels regarding the sustainable environmental protection.
