But the steel industry has been doing the same thing (with largely the same facilities) for the last 50 years. The move to recycling and mini-mills is the biggest change in the last 40 years. The same is largely true of aluminum mills. You should be able to figure out how to make that safe, but you won't make anything, if you demand that everything be as safe the first time as it will be in industries, which are a century old.
