A. Background of the Study
Nowadays, waste are scattered all around. Burning them is one of the ways to hasten waste but it can only add pollution to our environment. So the researchers decided to think of some ways to recycle them and bulletin board making is an example of it. It can help lessen waste and save money and trees. Cork is the main component in making bulletin board. It is harvested for commercial use primarily from Quercus suber (the Cork Oak), which is endemic to southwest Europe and northwest Africa. It reaches 25-30 years for the cork to be removed from the tree for the first time. In the Philippines, there is no production of cork and the country only imports cork in the western countries. It is reason for its high value in the market. The researchers conducted the study to replace cork in making bulletin board. The researchers used peanut shells and carton as an alternative of cork. Peanut takes 120-150 days for its harvest time. Unlike the cork, it only takes lesser time for peanuts to be harvested and it has a lower price in the market. The cellulose in peanut shells makes them ideal for use in drywall and paper products. It also contains arsenic that is commonly used in wood preservation.
B. Statement of the Problem
This study generally aims to makes use of peanut shells and carton as bulletin board.
This study specifically aims to:
* Determine which of the following ratios is appropriate in making bulletin board. * Test its durability and quality.
* Compare it to the commercially made bulletin board.
C. Significance of the Study
The result of this study will determine that peanut shells and carton can be use as a bulletin board. Recycling items that you would otherwise throw away helps to benefit us in terms of designing and into a satisfying sense. So, it is imperative to adopt recycling methods so as to sustain a healthy balance in the ecological system. As the natural resources are being utilized at a whopping high rate, they reinforce the cognizance of recycling in a big way so that they provide the factor reusability. D. Scope and Delimitations
The researchers only aim to know whether peanut and carton can be used as bulletin board. The carton and peanut shells were individually stripped and shelled. Moreover the researchers only used blender in disintegrating the components. It could not guarantee that the said sample could compete in terms of desirable properties with the commercially made ones. The researchers only covered the effectiveness of the product with the materials and proportions used. It is beyond their limitations that they only have limited time making the investigatory project, which is why they didn’t conduct further research improving the study. E. Review of Related Literature
Peanut shells are used frequently in industry. Today, peanut shells are used in linoleum (a mixture of organic materials such as linseed oil, rosin, wood flour, etc., on a burlap backing). They can also be found in plastic "lumber" made from recycled materials. The cellulose in peanut shells make them ideal for use in drywall and paper products, while their texture when crushed make them a useful ingredient in abrasives. Their absorption properties lend themselves to use in manufacturing activated charcoal. Currently, scientists are...
