Does the fact that an aluminum extraction plant commits environmental violations affect the ruling on working with aluminum extracted from it?

If it is proven that the method of aluminum extraction harms the environment and is legally prohibited, then the factory owner must abandon it, based on the Hadith: "There should be no harm nor reciprocating harm," and the saying: "The origin of everything that causes harm is prohibition." The prohibition is not for the permissible action itself, but for causing harm to people. If dealing with him is an inducement for him to manufacture what is harmful, or if the law prohibits dealing with him to avert harm and achieve public interest, then it is not permissible to deal with him in this regard, and he should be advised to abandon it. If a purchase is made from him despite his violation, the purchase is valid and your activity is permissible, but you have assisted the factory owner in what he is not permitted to do.
