Info on getting a Factory Green?

I would like to see this steel mill near where I live become green. I wanted to get some more rescores that I can give them on this. I would not think it to be a hard process, everything they do is recycling. I guess ISO 140001, or something like that? They are ISO 9001 and the two are closely related. This is more then a pipe dream, as this is the family business.

are you asking for ideas to make a factory green?
