If you recycle 10kg of steel, does that mean you'll get 10kg of steel back or less?

Question

If you recycle 10kg of steel, does that mean you'll get 10kg of steel back or less?

Answer 1

no but it does mean that you prevented 100 tonnes of raw ore that would have been smelted to make 10 kgs of the finished product.Imagine all the energy that you saved

Answer 2

Not necessarily. What actually happens is this:

Scrap steel reduces related water pollution, air pollution, and mining wastes by about 70%. It takes four times as much energy to make steel from virgin ore. Annually, enough energy is saved by recycling steel to supply the city of Los Angeles with almost a decade worth of electricity. (Source: National Polymers Inc.)
