ECO-FRIENDLY EXTRACTION, CHARACTERIZATION AND MODIFICATION OF MICROCRYSTALLINE CELLULOSE FROM OIL PALM EMPTY FRUIT BUNCHES

There is a widespread availability and massive generation of oil palm agro-wastes in Malaysia, that can be exploited for value-added products. This however requires coordinated effort to manage the wastes in an integrated manner whilst benefiting from its downstream development. Our study describ...
