Introduction
• Sago pith residues - one of the abundant lignocellulosic residues available in the state of Sarawak, Malaysia
(Apun et al., 2000)
•
2,556 tons of sago pith residue are generated from sago mills annually. This waste is usually drained into nearby rivers together with sago effluent without proper treatment, leading to environmental problems
(Linggang et al., 2012)
•
Sago pith residues usage: animal feed, compost for mushroom culture, for hydrolysis to confectioners’ syrup, particle-board manufacture, and as substrate for local microbes to produce reducing sugars and enzyme.

Sago palm- are those species of the genus Metroxylon belonging to the Palmae family.
(Singhal et al., 2008)
Extremely hardy plant, thriving in swampy, acidic peat soils, submerged and saline soils where few other crops survive, growing more slowly in peat soil than in mineral soil.

Sago solid residue; bark and ‘hampas’ are largely composed of celluloses and lignin, therefore, both a waste and a pollutant .
