The diagram below illustrates the recycling process of plastic bottles, outlining the transformation of waste into usable products.
The process involves nine stages, from collection to production, which can be categorized into three primary phases: collection and sorting, mechanical and thermal processing, and product formation.
The initial stages of the recycling process involve the collection of plastic bottles from trash, followed by transportation to a recycling center, where they are sorted and compressed into blocks. Subsequently, the blocks are crushed into smaller pieces using a machine, and then washed to remove impurities.
The crushed and washed materials are then transferred to a machine that produces plastic pellets, which are further heated to form raw materials. These raw materials are ultimately used to manufacture various products, including T-shirts, pencils, containers, bottles, and bags, thereby completing the recycling cycle.
