Researchers at the University Teknologi MARA in Malaysia have discovered cotton and palm kernel seeds to be suitable for production of biodiesel.

Using the reactive extraction method, wherein biodiesel is extracted directly from seed particles, researchers found that biodiesel from cotton seeds could lower carbon monoxide, nitrogen oxide and smoke emission in internal combustion engines.

In order to maximise outcome of biodiesel production, they investigated how seed particle size influence the amount of oil, extraction efficiency of reactive reaction and biodiesel conversion.

Results showed that the smallest cotton seed particles, which were 0.5 – 1 mm, produced the biggest amount of oil as well as a high percentage of extraction effectiveness. The same was true for palm kernel seeds with the smallest range yielding the greatest outcome (58 per cent) within 24 hours reaction time. The same size groups and reaction period showed 90 per cent of the extraction efficiency of fatty acid methyl esters (FAME).
