PVC has two characteristics: first, it contains chlorine; second, a large amount of additives must be added to stabilize it, and these additives include metals such as lead and cadmium, which are widely used in various industries. A product should be a process from creation to disappearance. Most enterprises only focus on the production and usage process of PVC. Which domestic companies are involved in the recycling and processing of waste PVC? When burning waste PVC, the poison of the century, dioxin, is produced. What are the main treatment methods for PVC in China at present? How much PVC is recycled? Many developed countries abroad have phased out the use of PVC. The domestic situation is concerning. . .
The first problem can basically be solved; non-toxic stabilizers are already widely used, such as organotin stabilizers and calcium-zinc stabilizers. The second issue is that there are few companies engaged in PVC recycling; basically, it’s small enterprises or workshop-style businesses that handle this task. It should be given proper attention.
