Biomass residues from palm oil mills in Thailand: an overview on quantity and potential usage.

Abstract

A study of the quantity and potential usage of palm oil mill wastes in the south of Thailand was carried out. Sixteen palm oil mills in the region generate 386 930, 165 830, and 110 550 tons/year of empty fruit bunches, palm press fibre (PPF), and palm kernel shell (PKS), respectively. In addition, 1 202 260 tons/year of waste water is treated anaerobically. Only the pericarp fibre is used for boiler feed. Empty fruit bunches (EFB) and the shells are disposed of in landfills, which was costly. In some factories the empty fruit bunches are burnt in furnaces causing air pollution. Potential usages of the solid and liquid wastes are suggested, including coir fibre, fibre board, cement board, roofing tiles and card paper from EFB, soil amendments and mushroom compost from PPF, energy from PKS in modified furnaces, and the use of waste water for irrigation and fertilization of the palm trees (Elaeis guineensis).
