A REVIEW PAPER OF DESIGN AND FABRICATION OF PLASTIC SHREDDING MACHINE

Mechanical Engineering and plastic waste management

Today the world is facing a huge problem of waste management. Multiple industries like construction, manufacturing, medical, automobiles, food industry, packaging, etc. have plastic playing a vital role. Plastic is one of the most used materials due numerous advantages. But plastic has many serious disadvantages which can harm the ecosystem. Plastic if disposed unsafely, then it can lead to degradation in quality of soil, water, air and all the natural resource. Plastic waste has the highest percentage of non-biodegradable waste. The plastic waste cannot be incinerated as it will emit hazardous chemicals into the environment which lead to increase in environmental pollution. As the plastic waste does not decompose, it will require huge space for storage in landfills. This plastic waste is very difficult to store as it has large volume. Hence breaking down the plastic waste into very small piece can help the problem of storage. A shredding can be used for effective management of plastic waste. This paper gives information regarding design of shredding machine. This machine can be used for breaking down the plastic waste into small manageable size. The blades of shredder are designed in a way that they withstand the forces during cutting of plastic parts. These small flakes of shredded plastics then be recycled into numerous ways. The main consideration for this design is cost effective and efficient. Thus, the use of shredding machine can also reduce the labor cost. This will hence reduce the burial and dumping of waste in the earth.
