Abstract

Kamani or Calophyllum inophyllum is a non-edible seed which has potential to be a feedstock for biodiesel. Kamani trees are mostly found around coastal areas and are also known as forest trees. Kamani seed can be a promising alternative feedstock due to its high oil yield, simple cultivation procedure and non-edible seeds whereas palm oil which is currently used as biodiesel feedstock has environmental concerns and it is also produced for food thus raising issues about food versus fuel. The analysis of the energy inputs and outputs from kamani biodiesel show that its production is efficient because energy from output is higher than the input. Kamani biodiesel can also be considered renewable because its renewability factor at 1.95 (kamani biodiesel only) and 4.43 (all products) are substantially higher than 1.
