| Summary: | Agro waste can be defined as a waste-wealth from agricultural plant. Oil palm
leaf and corn stalk can be categorized as agro waste material. Fibre resources for
pulp and paper are obtained from trees or agricultural crops. An oil palm leaf
is one component of oil palm waste generated in Malaysia. In Malaysia, with
large area of plantation of corn plant with around 8,600 Ha in 2010 and it
generates large quantities of corn stalk discard as wastes. The corn stalk residues
produced after harvesting season is an environmentally friendly source for the
production of cellulosic fibre. At first, the comparison between oil palm leaf
and corn stalk by mechanical properties from soda pulping process. After that,
next method was focusing on surface characterization by Scanning Electron
Microscopy (SEM). Both materials have a potential due to the mechanical
properties (tensile, tear, burst and fold) and surface characterization, but corn
stalk show more in strength and compactness due to fibre characterization
compared to oil palm leaf. From this study, a corn stalk paper has a tensile index
of 9.1 Nm/g, compared oil palm leaf, 7.9 Nm/g; Oil palm leaf has a tear index
(1.8 Nm2/g) compared corn stalk (1.2 Nm/g); Corn stalk gives a good of burst
index about 6.6 kPa*m2/g rather but oil palm leaf shows low in burst strength
(0.9 kPa*m2/g); Folding test, corn stalk gives 2.5 Nm compared to oil palm
leaf, 1.23 Nm. Corn stalk fibres show a closely packed arrangement and thicker
fibre compared oil palm leaf. This study promoting the green technology in
developing a friendly product and suitable to be used as an alternative pulp in
paper making industry |
