Abstract

Objectives: To develop and test a crayon recycling device in terms of power consumption and quality of the product in terms of vibrancy of the color, coloring ability and strength and cost of production. Methods and Analysis: The researchers tested the quality of the product in terms of vibrancy of the color and coloring ability with a remark perceived by the raters that there is no significant difference among treatment 2 and 3. In treatment 1, the bigger broken crayons took a longer time to melt and leave hollow space in the core part. In treatment 3, the smaller chopped crayons at .25-inch length has the shortest time to melt and is evenly solid at the core part. The researchers used manually fabricated melt pan situated above the heating element. It was observed that using the melt pan in the melting process is very useful because it took a short time to liquefy the crayons. In the quality of the crayon, comparing the other three treatments with treatment 1, a highly significant difference exists due to the composition of the crayon as well as the strength of the product with a remark that treatment 1 and treatment 2 shows that it can carry a total load of 19.614 N before the product breaks. Findings: From the discussion and analysis of the gathered data and findings, the crayon recycling device is efficient and can be used by the stakeholders in creating visual arts and can compete with the commercialized crayon recycling device. Based on the results and discussions, the following conclusions were drawn from the study. The crayon recycling device is efficient in producing quality recycled crayons which are comparable to newly produced crayons. Applications: The crayon recycling device is very efficient in terms of its power consumption. It is also economically viable in recycling small pieces of crayons.
