CASTOR BEAN ( ricinus communis ) AN INTERNATIONAL BOTANICAL ANSWER TO BIODIESEL PRODUCTION & RENEWABLE ENERGY

LEADER IN ORGANIC BIOTECHNOLOGY

MOTIVATION FOR THIS STUDY
Castor Bean (ricinus communis) has beenwidely accepted as an agricultural solution for all subtropical and tropical locations that adresses the need for commercial crops with low impute costs and at the same time provides traditional farming with a viable income from current non productive lands: • Castor Bean does not compete with food crops, as Castor Bean can be grown on marginal lands, which are not competitive with food productionlands. • Castor Bean is not competing with food grade oils. • It’s toxicity is sensed by animals and therefore not foraged on. • It is high yielding, yielding as much as 350-650 kg of oil per hectare when no maintenance is applied to the crop i.e. fertilizers etc, to a high end yield where annual rainfalls happen at the right times, (1000 liter per hectare). • It has a very high oil content ofapproximately 50%. • The oil seed is collected by hand, by picking the ripe pods from the plant. • It requires only moderate rainfall (approx. 600mm only) and can withstand long periods of drought, but will thrive under higher rainfall. • It is an uncomplicated crop that requires little attention during its growing periods. • Due to its low demand on soil fertility, it is ideal to replant marginallands to prevent desertfication and erosion.

Given the simular geographical, climatic and lack of rural employment opportunities, growing a crop for renewable energy provides the answer for long term prosperity. It is generally accepted that no matter how much oil seed is produced, there will not be an over supply for many decades to come. DOVE BIOTECH has long appreciated both the economicbenefits and ecological benefits of planting Castor Bean (ricinus communis) for bioenergy production. Combined with Dove Biotech’s “State of the Art” technologies for Biodiesel and Biogass, Castor Bean (ricinus communis) there are both short and long term benefits for a truly holistic bioenergy projects in developing and developed countries in the tropical and sub tropical belts of the world.
