Recycled Wood Bark Of Malunggay

El ij ah D an ie l B . Ge an ga I I-On yx Kevin R ey C . Rio veros II -O ny x RECYCLED WOOD BARK OF MALUNGGAY (Moringga Oleifera) AS HANDMADE PAPER Problem: What will be the texture, cost value, and acceptance in the market of paper if recycled wood bark of malunggay is used in making it?

Hypothesis We think that if recycled wood bark of malunggay is used in making paper, then its texture will be rough, it is cheap, and it will be acceptable in the market.

Experimental Design Controlled Variables: Amount of dried malunggay bark Amount of chlorine Amount of caustic soda Amount of Venus dye Manipulated Variable: The type of material used in making paper

•

Responding Variable:

•

The texture, cost value, and acceptance of the paper

Materials: Raw Materials: 500 grams of dried malunggay bark 50 grams chlorine 100 grams caustic soda Other Materials: 2 grams Venus Dye Mold and Deckle Silk Screen Cloth or Net Bag Weighing Scale Mortar and Scale

Procedures: I. Preparation of materials

The barks of Malunggay stems are removed. The outer skin was scraped off and bark was stripped off from the inner wood. Then the barks were sun-dried. The materials were first prepared before the experiment

II. Boiling of Malunggay Barks The dried barks were boiled in caustic soda and water for 2-3 hours. Then the barks were washed to remove chemicals. They were then pounded to produce wood pulp.

II.a. The dried barks were boiled in caustic soda for 2 – 3 hours. II.b. The barks were washed to remove chemicals. II.c. Then pounded to produce wood pulp. II.d. Produced Wood Pulp

III. Bleaching and Dyeing of the Wood Pulp The pulp produced in the process was bleached using chlorine. After bleaching, it was washed to remove chemicals. The wood pulp was soaked in water for 5-15 minutes to make it whiter. Then the wood pulp was boiled in dye and water for about 15 minutes.

IV. Molding and Drying of Wood Pulp The dyed wood pulp can now be molded. Using the mold and deckle, the wood pulp mixed with water was molded. To dry the pulp, place it on an even wall or screen to let it dry. When the pulp has already dried, strip off the paper from the wall. The paper produced. Data Gathered After we had produced the paper out of the Malunggay Bark, we asked somebody to rate the tear strength, texture and acceptance of the paper.

Co nclus io n: Our hypothesis was right. The texture of the paper out of Malunggay Bark is rough. It is acceptable in the market, and it will be cheap if sold, because the materials are not expensive.
