Abstract: Environmental awareness has become very significant in the uprising world especially in the packaging industry. Depleting forest resources to obtain wood which is the major raw material for conventional pulp and paper production worldwide, had made a significant impact on the environment and human. This has made the search for alternative fibre in non-wood materials imperative in pulp and paper production. They are readily available and can be extracted from plant leaves at very low costs given that most are agro waste. In this research, two kinds of paper were made from fresh pineapple leaf agro waste using the conventional (CV) and Microwave-assisted (MW) method at 80 g/L NaOH for 15 mins. The papers were characterized for their Young’s modulus of elasticity, E, and were compared with a standard bread packaging papers control. The E for papers were 0.08 ± 0.02 GPa, 0.49 ± 0.03GPa and 0.34 ± 0.01 GPa for CV MW, and standard Market papers respectively. The moisture content calculated from the study showed moisture content (MC) of 85.95 ± 0.31%, for leaves used for paper production (PP). The MC of the papers were 10.33 ± 0.31 %, 12.55 ± 0.47 % and 12.36 ± 3.18 % for CV, MW and Market paper respectively. Papers produced from the MW method were stiffer than standard Market papers (control), hence pineapple leaves could be used as an efficient and cost effective source of pulp for food packaging materials using the microwave assisted method.
