Sedley is a chemical fiber factory that produces viscose fiber. The factory will use some flammable, explosive and toxic chemicals, such as H2S, H2SO4, CuSO4, ZnSO4 and NaOH.

In the production process, H2S will react with H2SO4 to generate highly toxic gas H2S, which is very toxic and smells like rotten eggs.

Copper sulfate and zinc sulfate are easy to cause heavy metal pollution.

Strong alkaline NaOH can also pollute water sources.

At the same time, it will also use the highly toxic gas CL2 in the production process.

However, general chemical fiber plants will consider these problems in their design and treat their toxic and harmful wastes. Generally, the surrounding environment will not be much better, but the toxicity will not be particularly great. It will definitely have a certain impact on the surrounding area.
