1. Banana saba and corn peelings were obtained. About 250 g of each peeling were sun-dried for about 2 hours, until their moisture content was noticeably depleted. These were then cut into smaller strips, approximately 5 cm long and 0.5 cm wide.





2. The use of Banana Saba (Musa compressa) and Corn (Zea mays) Peelings as Components of Handmade Paper





3. Will the addition of Banana saba and Corn peelings strengthen the quality of recycled paper?





4. A. Folding Endurance TestThe calculated value made by ranking of 10 panelists showed proof of the feasibility of banana saba and corn peelings as components of handmade paper. B. Tear Factor TestThe test for tear factor showed that there is a significant difference between the samples with respect to their amount of tear.

6. Two of the Philippines’ widely harvested crops are banana and corn. Due to the large production of these crops, large amounts of their peelings accumulate as waste every year. Meanwhile, in a world where virgin forests are quickly being depleted, recycling paper has become a must. In light of this, the group will try to use different agricultural fibers to strengthen the quality of recycled paper.





7. The group would like to thank Dr. Clarasa and her staff at the Fiber Industry and Development Authority for their assistance.





8. R.V. Visperas (1995) identified various raw materials that can be used in the production of handmade paper. These include natural fibers (abaca), agricultural wastes (banana and bagasse) and semi-processed materials (recycled paper).Peralta (1993) stated there are properties of paper that need to be noted, besides the standard tests for strength. Among these are proper dimensions, optical properties, and permeability.





9. It was found out that corn peelings are acceptable raw materials saba peelings are rejected as components in handmade paper production. Perhaps the presence of dagta in the banana saba peelings was a factor in the low quality of paper.





10. The main goal of this research is to produce quality handmade paper using banana saba and corn peelings. Recycling paper has become a must due to destruction of virgin forests. One of the main reasons however, why recycled paper is not very popular to consumers is its low quality compared to virgin paper.
