The residue of the palm oil press consists of a mixture of fibers and palm nuts. Nuts are separated from fiber by hand in a small-scale operation.
The sorted fiber is covered and allowed to heat, using its own internal exothermic reaction, for about two to three days. The fibres are then pressed in an ingot press to recover secondary (technical) oils commonly used in soap making.
The nuts are usually dried and sold to other operators who process them into palm kernel oil. Sorting is usually left to the young and old in the village to help them earn some income.
