Introduction
• to develop a Pure Plant Oil diesel substitute from native oil seeds• to produce sufficient amounts for all power and transportation needs• one village, three canoes, three generators – ca. 6,000 l / year• local diesel price extremely high • if successful, eventually all six villages will grow their own fuel

• assessed and trialed wild oil fruit potential
• three conversion systems installed
• 1,000 Jatropha trees planted• oil pressing infrastructure established

• new strategy – from wild to cultivated• converted engines operate flawlessly• secured continuation of project via
alternate source of funding• combined food & energy sovereignty

Challenges
Initial wild feedstock not suitable• insufficient stand density• ratio of overall fruit to oil bearing part too
high – insufficient yield
Challenges
Seeking new strategy• need for alternative feedstock • organic agroforestry Jatropha
required longer timeline
