Shredding Machine Development for Recycling Process of Waste Plastic Bottles

Ejiko SO

Plastic is one of the most available materials in the world today, but its waste is bedevil with serious environmental pollution and landfill space exhaustion. Waste plastic recycling is a process of recovering material that are useful making new plastic products such as plastic lumber, containers and particle boards. In accomplishing this task waste plastic is require to be shred first into smaller pieces, facilitating the movement for subsequent processing. A shredder was designed and constructed with locally sourced materials to reduce the volume of commercially used plastic bottles into smaller pieces or for further processing into useful products. The shredder has a feeding unit, a shredder unit, a power transmission unit (2 HP) with single phase. The performance evaluation of the machine showed that the machine has efficiency of 34%. The machine is suitable for the control of waste plastics in the environment.
