Jatropha (by)products
Straight vegetable oil (SVO) is an indirect substitute for bio-diesel, petro-diesel and a direct substitute for fuel oil. Jatropha SVO is the least capital intensive Jatropha fuel supply chain that enables small-scale farmers and producer cooperatives to maximize value added to the end product in the local economy. Jatropha SVO can be consumed in diesel engines that have been converted to run on SVO fuel. Examples of Jatropha SVO ready engines are most fuel oil engines and low-speed, gravity fed Lister type engines running under 1200 RPM. These types of engines have strong competitive advantages in the production of local electricity, grinding mills, seed crushing operations, water pumps, irrigation, and small industry due to lower fuel costs associated with SVO fuel relative to bio-diesel, petro-diesel and fuel oil. Approximately 75% of Haiti’s electricity is produced in large, fixed-speed diesel engines creating a large potential demand for Jatropha SVO fuel. SVO engine and conversion system technologies have been around for nearly a century and have been proven with Jatropha SVO in Africa and Asia.

Bio-diesel is a direct substitute for petro-diesel fuel that is equally efficient and has the potential to burn cleaner than petro-diesel if quality standards are met.  Bio-diesel can be used purely in diesel engines as B100 or blended with diesel (at any percentage) creating flexible and low-switching cost consumption. The majority of Haitian liquid fuel consumption is in the form of petro-diesel and fuel oil, both of which use compression ignition engines and are ideal for use of Jatropha bio-diesel. In addition to substituting petro-diesel, Jatropha bio-diesel is a less-toxic substitute for kerosene fuel used in Lamps and stoves. Biodiesel applications in lamps and stoves will have the largest impact on rural villages for light and cooking.

High-protein animal feed is a potentially high-value product derived from non-toxic Jatropha varieties. Jatropha seeds maintain high-levels of protein creating an opportunity for Jatropha to produce energy, food and animal feed in larger quantities than soy beans would. Haiti currently imports animal feed that is too expensive for small-scale rural farmers, effectively creating a large barrier of entry for animal husbandry, such as chicken, tilapia, and dairy farming. Unlike soybean, Jatropha can be grown on land that is not currently utilized for traditional food crops making Jatropha a very attractive crop for Haiti.

Charcoal briquettes are an ideal by-product from Jatropha fruit shells and hulls. Charcoal is the primary fuel used for cooking in Haiti and is largely responsible for the rapid rates of deforestation in recent decades as a result of hardwood being the primary input for charcoal production.

Cogeneration Fuel is derived from Jatropha fruit shells and hulls which are burned directly in co-generation systems, producing both heat and electricity in a distributive energy infrastructure relevant at the village level.

Honey, produced from Jatropha flowers is a high-value Jatropha product that adds value at the local village level. Jatropha is pollinated by insects, primarily honey bees, creating ideal conditions for honey bee propagation in conjunction with Jatropha farming. By producing honey with Jatropha pollen, bees enhance Jatropha fruit production which equates into higher oil yields per tree and hectare.
