Designing of Robust Economical Food Grade Plastic Recycling Unit

Abstract

Plastics are inexpensive, lightweight, and durable materials, which can be ready, to be modeled into a variety of products that uses in a wide range of application. As a consequence, plastic has increased markedly over the last 60 years. The current level of their usage and disposal generates several problems. Around 3-4% of worldwide oil or gas production a non-renewable resource is a feedstock for plastic production. This plastic produced each year is used to make a disposable item that is used for packaging like food-grade plastic packaging which is very short-lived and disposed of within weeks and months. This observation alone indicates that our current use of plastic is not sustainable. Because of the durability of plastic polymers, they often end up in landfill and natural habitats worldwide. So recycling is one of the best options which can reduce the use of oil, carbon emission, and the quantity of waste requiring disposal. Recycling is one of the most important actions currently available to reduce these impacts and represents one of the most dynamic areas in the plastic industry today, taking these things into consideration for designing a “Food Grade  Plastic Recycling Unit” The machine employs the principle of melting food grade plastic and extruding it into a pellet. This machine consists of a hopper to feed the LDPE plastic pieces to the heater and extruder. The extruder melts the LDPE plastics into the molten fluid at a temperature between 115-150˚C through induction heating, the screw inside pushes the molten plastic out. The screw is driven using a motor and this molten plastic is cooled and cut into pellets which can be used to form new products.
