What procedures do companies need to go through to recycle (buy), crush and sell waste plastics?

There are many kinds of business licenses before the recycling of waste materials, such as the qualification of plastic recycling of dangerous goods such as scrap metal and chemical waste (provincial environmental protection department), and this threshold is relatively low. If it is broken, it will be much easier. Just go to the crusher yourself. If it is processed into plastic particles, it is necessary to apply for ring guarantee. If no one in their own small processing factory is qualified, many small self-employed people do it. If it is a factory, it is suggested that every step should be done well, and the qualification of production and processing license and environmental protection qualification should be recycled. This local industrial and commercial bureau will do.
