Decanter cake (DC) and boiler ash (BA) are wastes from the palm oil mill. A mill with 90 t hr-1 FFB processing capacity will produce about 160- 200 t DC and about 180 t BA a month. Both the DC and BA are sources of nutrients for producing bio-compound fertilizer. Recycling them will reduce the cost of palm oil production.
