Abstract

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
