Prospects of Tectona Grandis as a Feedstock for Biodiesel

Abstract

The limited availability of fossil fuels has encouraged the need of replacement fuels of renewable nature. Among the renewable fuels, biodiesel 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 synthesis of biodiesel from T. Grandis oil was done with transesterification reaction giving high percentage yield of biodiesel which reached to 89%. The T. 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, the present study reveals that T. Grandis seed oil is reliable for the production of biodiesel with encouraging probability in future.

Unlocking the potential of teak seed waste: carbonization for sustainable resource transformation

“…12,13 This information informs its various applications in different bioprocessing-related areas such as seed meal production for animal feeding, 13 biocoagulant production for the reduction of turbidity in well water, 14 and biodiesel production and its blending. 15 However, there is limited information on its uses and applications in thermochemical processing.…”

“…Researchers have confirmed that the seeds of the teak tree ( Tectona grandis ) have a high crude fiber content of around 26.0% and a rich content of amino acids, such as methionine and lysine, at concentrations of 4.19 and 7.60 g per 16 g of Nitrogen, respectively 12,13 . This information informs its various applications in different bioprocessing‐related areas such as seed meal production for animal feeding, 13 biocoagulant production for the reduction of turbidity in well water, 14 and biodiesel production and its blending 15 . However, there is limited information on its uses and applications in thermochemical processing.…”
