Recycling of plastic is very productive way of utilizing the plastic source as it would help the human kind in protecting the environment from the hazardous plastic wastage which creates global warming and many other changes in the environment.Plastic recycling is the process of taking the scrap plastic and reprocessing them into the useful products is termed as recycling of plastic. There are many companies which are undergoing these kinds of process using waste material and gaining best of it, one such is Plastic Solutions Australia which helps in clearing the scrap of plastic and gives us the best of the recycled material. Before recycling all these scrap plastics are segregated based on the type of resin material of which they are made of. In this process we have many stages of recycling the plastic which can be discussed below.
Stages of Recycling:
Mainly recycling of plastic is done in two ways that is:
- Mechanical segregation and washing:
In this process the scrap plastic is washed neatly and chopped into powders and melted, and again converted into reusable plastic which has an end product of converted reusable plastic.
- Chemical Recycling:
In this process the scrap plastic is being broken into monomers and again used into reusable plastic material. In this chemical process only, it takes much time to get the end product as the chemical compositions are required correctly to recreate the plastic to reuse them.
After completion of mechanical segregation and cleaning them these plastic pieces are shredded into small compounds and then used for remake of new plastic items.
Plastic Pyrolysis is the method of converting the petroleum-based wastage like plastic into fuels and carbons. In this pyrolysis oil is also extracted which can be used to generate the power but with very less efficiency instead of diesel and gasoline which is at least helpful to some extent not completely though. Though the chemical properties of commercial oil and as well this pyrolysis oil are one and the same except the viscosity which is high in this pyrolysis oil, else these two oils are one and the same in the chemical composition. There are three types of plastic recycling pyrolysis suitable plastic materials they are as below:
- Mixed Plastic.
- Mixed wate plastic from waste paper mills.
- Multi layered plastic.
In this process all the sorted scrap plastic material is been taken into the heat compressor and rotated and all the scrap material undergoes this compression then all the varieties of the scrap plastic get converted into molten form which can be moulded into the required forms and get the end product. This method is though criticised by many scientists as it requires more of energy to do this.
This is the process of recycling the plastic and using them in a productive way.
