塑料瓶回收的九个步骤Recycling plastic bottles nine stages

The diagram illustrates the stages involved in recycling plastic bottles. Overall, the process consists of nine steps. After being placed in the recycling bins, the bottles undergo stages like compression, crushing, washing, and heating to transform into raw material, which is then used in the manufacturing of new products. In the first stage, used plastic bottles are collected from bins and transported to recycling facilities by specialized trucks. Upon arrival, recyclable bottles are separated from non-recyclable waste. The selected bottles are then compressed into compact cubic blocks, which are subsequently crushed into smaller fragments. Following this, the crushed pieces are transferred into a large container where they are thoroughly washed. In the next stage, the cleaned fragments are processed through a machine that converts them into plastic pellets, which then go through a heating process to produce raw plastic material for the production of various plastic items, including new bottles, bags, and containers. These products, once used, can be recycled, creating a circular process.
