Abstract
The limited availability of fossil fuels has encouraged the need of replacement fuels of renewable nature. Among the renewable fuels, biodiesel that produced from oil seeds and food wastes has been favored by the majority of researchers. In this study, Tectona Grandis seed oil has been investigated as a non edible feedstock for biodiesel. The oil content of seed is 43% which makes it suitable for commercial production of biodiesel. The production of biodiesel from Tectona Grandis oil was done with transesterification reaction giving high percentage yield of biodiesel which reached to 89%. The Tectona Grandis biodiesel was subjected to determine various physicochemical parameters by standard testing methods and found in agreement with the ASTM D 6751 and EN 14214 standards. The fatty acid methyl ester composition for the biodiesel is composed of 42.71% oleic acid, 13.1% palmitic acid and 31.51 % linoleic acid.. The biodiesel showed low oxidation stability which is attributed to high percentage of unsaturation. To address this issue, synthetic antioxidants were added to increase its resistance towards oxidation. By considering all the parameters, present study reveals that the Tectona Grandis seed oil is reliable for the production of biodiesel with encouraging probability in future.

Implementation of biodiesel from Tectona Grandis (TG) will lead to many advantages such as providing greenery, support to agricultural economy, reduction in dependency on imported crude oil and reduction in air pollution
Summary
The energy generated from the combustion of fossil fuels has enabled many technological advancements and social-economic growth. The increasing demand of energy and environmental concerns arising due to the use of traditional fuels has become a threat to the sustainability of our ecosystem and sparked the need of energy sources of limitless duration with a smaller environmental impact. Biodiesel falls in the category of such fuels of renewable nature (Hu et al, 2004; Gui et al, 2008; Ullah et al, 2014). To address the issues related to pollution with petro-based fuels, Government of India has taken steps toward usage of biofuels. In this context, the Ministry of New and Renewable Energy has proposed 20% blending of transportation fuels, namely, diesel and petrol with bioethanol and biodiesel as a national biofuels policy by 2017 (Government of India, 2009). The contribution of energy from biomass has been estimated as one fourth of global energy by 2050 (Hossain and Davies, 2013)
