The use of recycled fibers in the Malaysian paper industry has been an
economic and environmental necessity due to the limited availability of virgin fiber.
However, with each recycling, the paper strength decreases, hence different methods
are employed to increase its strength potentials. Various forms of oil palm cellulosic
materials viz. OPEFB-UB. OPEFB-OZP, OPEFB-MCC and OPEFB-TEMPO were
used to enhanced the strength properties of the recycled paper that were obtained
from the old corrugated container (OCC).
