Sclerocarya Birrea Plant Oil: A Potential Indigenous Feedstock
for Biodiesel Production in Botswana

Abstract - Exploring new feedstocks for biodiesel production is now receiving widespread attention
world-over. This paper presents experimental results on properties of celerocarya birrea plant oil.
Chemical properties analysis of birrea plant oil were performed using gas chromatograph and mass
spectrometer, while the engine performance tests were conducted on a variable compression ignition
engine. Parameters such as fuel consumption, engine torque and engine brake power were recorded at
different engine loads for pure diesel fuel and birrea plant oil. The experimental results indicate that birrea
plant oil offer immense potential as both fuel and feedstock for biodiesel production. The performance
characteristics of ignition compression engine using birrea plant oil indicate that the optimum
compression ignition engine occurs at 60% engine load. Similarly, the results revealed that variations in
specific fuel consumption recorded for diesel fuel (D100) and birrea plant oil (BPO) between 30% and
60% show no significant difference for the fuels under review.
