A good example is steel which uses huge amounts of iron ore and coke to make it. In the process of making the steel there is a lot of waste products making the finished product lighter. Because of this weight loss industries tend to loe near to the raw material they need because transporting the finished product is cheaper.
2. Steel making came under increasing competition from cheaper overseas producers. The Massive Redcar works was shut (again) in 2015 after the Thai owners SSI, pulled out blaming higher energy costs and unfair competition from producers in other countries.
