Newspaper and rice hull as an alternative material for plywood production

Using the combination of newspaper and rice hulls, from waste materials as an alternative for Plywood Production. Science Investigatory Project Adviser of Ampayon CES teacher came up with an alternative solution that could possibly eliminate the rice hulls waste in the community.

In the study, newspaper and rice hulls are used as alternative in making ply sheet, these two alternatives are chosen because of its availability.

They mixed the collected materials such as newspaper, rice hull, and wood glue by using a blender and place it in a molder as thick as the marine plywood. Then let it dry for one (1) month. After the samples are identified. It is subjected to tests.

The Equi-Parco Construction Company located at P-3 Ambangan, Ambago, Butuan City, Agusan Del Norte which has testing laboratory to tests which determine the flexural strength, specific gravity and absorption test of the plywood.

In terms of flexural strength sample 1 got 31.63 seconds which has the longest time before it breaks/bend that makes it the strongest among the four samples.

Sample number 2 got 31.53 seconds which has the second longest time. Sample 3 got 31.28 seconds which has the third longest time. And sample 4 (commercial) got 23.06 seconds which has the shortest time before it breaks/bends that makes it the weakest among the four samples.

The commercialized product of marine plywood got 17.22 grams which has the highest absorption of water that makes it easily decayed.

Sample 2 got 14.42 grams which has the second highest absorption of water. Sample 1 got 13.59 grams which has the highest absorption of water. And sample 3 got 11.92 grams which has the lowest absorption of water because newspaper is a non-porous material.

After the three trials in burning the four samples, the following results shows the significant figures where sample 1 has the capacity to start igniting for about 2 minutes and 35 seconds.

This means it is a good indicator that sample 1 won’t fire up easily compared the other samples, samples 2 got 2 minutes and 23 seconds, marine plywood got 2 minutes and 13 seconds and lastly sample 3 got 1 minute and 74 seconds this means that it will easily ignite fire. 75% of rice hulls and 25% of newspaper can be used as an alternative ply sheet because of its durability.

Likewise, by doing so, it could help uplift the implementation of solid waste management to another level and where wise, efficient, and effectively used of rubbishes improve the economy as well. ###
