Abstract

Plastic pollution has become a global concern due to poor plastic waste disposal management. As an alternative, independent recycling efforts are necessary. A Plastic shredder machine is a preliminary machine used to cut plastic waste into small pieces before turning it into useful products. The concept design of the shredder machine that is currently available is fairly similar. The shaft and blades are the critical components in the shredder machine that determines its performance. The geometry and orientation of the blades that were fitted into the single or double-shafts were found to directly affect the shredding performance. Therefore, this article aims to review the various geometry and orientations of the blades that give direct effect on the shredding performance, as well as identifying the research gaps related to the shredder machine for plastic waste materials

Highlights

Plastics have become an integral part of society since the 1950s when their mass production commenced and their usage has continued to increase with population growth, the standard of living and technological development [1]

In Malaysia, the highest number of plastic wastes is of Low Density Polyethylene (LDPE) type, followed by High Density Polyethylene (HDPE), Polyethylene Terephthalate (PET), PS, PP and Polyvinyl Chloride (PVC)

Summary

Introduction

Plastics have become an integral part of society since the 1950s when their mass production commenced and their usage has continued to increase with population growth, the standard of living and technological development [1]. It is cheap, lightweight and easy to mould. Due to their versatility, plastics have replaced traditional materials such as metal, wood and leather [2]. Plastic is widely used in food and beverage packaging, textile, automotive, manufacturing, medical devices such as surgical equipment, drips and blister packs for pills [3]. The increasing usage of plastics has caused some substantial environmental pollution burden on both land and water habitats [4]
