The recycling process consists of several methods in them, such as thermal depolymerization, heat compression, distribution, and several other methods. There are several general central methods for all this. At first, plastic was collected both manually or in a mechanical way. Not all types of plastic have the same quality. Plastic bottles and heavy industrial plastic items cannot be destroyed by the same process.
Therefore, various types of plastic for plastic reprocessing are separated into various divisions. One of the criteria for determining this type is to check their resin type. Various plastic items have different resin strengths and qualities. However, the practice of determining the quality of plastic with the process of identifying the type of resin is part of the past and used less today. The method used in segregation is currently RIC technology. Another way to separate items is with their color.

Thermal depolymerization is about solving polymers inherent in plastic into petroleum. The advantage of this method is that one can lower and break down almost all types of polymers. Chemicals produced due to solving mechanical and chemical plastic are used as fuel such as petroleum.
Heat compression is one of the latest and very popular processes in countries such as the US and Australia. This is very effective in recycling all forms of plastic items. This is done by mixing all plastic together in a large drum equipped with metal teeth. When the drum is rotated, plastic polymers are broken down and then recycled. However, there is an important downside to this method too. It is said that while this method is very effective, the downside is that it spends a lot of energy!
