Abstract

Demand of renewable and clean energy to replace diesel world is big and urgent. However, edible crop oil as raw material is limited and its price is expensive and unstable. We want to look for new suppliers of raw materials, which should be cheap and supply stable to replace edible oil such as rapeseed and euphorbia extract. This study shows, the best candid for this purpose is Euphorbia tirucalli. It can be feasible and efficient to produce biodiesel in plant as stocks which contains terpenoids. Based on economic situation of oriental (Iran, UAE, Oman), several suggestions have been listed for development and promotion of biodiesel fromE. tirucalli. These lands can be used to grow biodiesel feed stocks plant and to produce non-food biodiesel feedstocks for the domestic energy market to diminish imports. Biodiesel is non toxic and environmental friendly as it produces substantially less carbon monoxide and 100% less sulfur dioxide emissions with no unhurt hydrocarbons and consequently it is ideal fuel for heavily polluted cities. Biodiesel reduces serious air pollutants such as particulates and air toxicity. This material can be used directly by a diesel-powered car. Also, biodiesel extends the life of diesel engines.

Key word: Euphorbia tirucalli, biodiesel, energy, air toxicity, engine.
