塑料瓶回收Plastic bottles recycling

The process diagram illustrates how plastic bottles are recycled. Overall, there are nine steps starting with bottles being thrown in the trash and ending with products being made from the recycled plastic, whereupon the process restarts. The first three steps involve collecting and sorting the plastic bottles. This starts with plastic bottles being thrown into garbage bins. Next, garbage trucks collect these bins. Subsequently, the plastic bottles end up in a recycling centre where they are sorted by hand into bottles that can be recycled and bottles that cannot. The next stages focus on preparing the recyclable plastic. This begins with compressing the recyclable plastic bottles together. These compressed blocks are then fed into a grinder that crushes them and transfers them into a tank where they are washed. Subsequently, plastic is put into a machine that transforms it into pellets. Looking at the remaining stages, the plastic pellets are heated and turned into raw material suitable for making plastic products. After this, finished products are created from the raw material. Some finished goods may end up being thrown out into trash cans and subsequently re-entering the recycling process.
