Developing a low-cost plastic bottle shredder to increase the amount of plastic waste transport for small entrepreneurs

Abstract

In this paper, the researcher has an idea to reduce the size of plastic bottle waste so that it can be increased in transportation and easily crushed to make plastic pellets for small entrepreneurs. Design and develop a plastic bottle shredder that has a low cost and can shred many types of plastic. The operating steps are Designed for the structure of a plastic bottle shredder with dimensions of height of 90 cm, width of 43 cm., and length of 54 cm. Methods for testing the performance of plastic bottle shredders are as follows: Take bottles made from 6 types of plastic: Polypropylene: PP, Polyvinylchloride: PVC, High-Density Polyethylene: HDPE, Polyethylene terephthalate: PET, Low-Density Polyethylene: LDPE, Polystyrene: PS and put them in a shredder by testing all 3, It was found that the shredder was able to shred all six types of plastic. The size of the shredded material decreased accordingly. Comparing the production costs with the machines sold in the market, it was found that the cost of the plastic bottle shredder that was built was lower than the price of the machines sold in the market. The results of the satisfaction study were collected from a sample of 10 small plastic bottle entrepreneurs in Nakhon Si Thammarat province. The tool used in the study was a questionnaire. The summary of satisfaction values in using the prototype plastic bottle shredder was the overall average satisfaction was the highest ( =4.75)
