What is the difference between closed-loop recycling and open-loop recycling?
The closed-loop recycling process represents recycling at its finest—remanufacturing a product back into the same product—like an aluminum beverage can which can be recycled into a new aluminum beverage can endlessly. The steel and iron industries use available steel scrap (old cars, construction materials, appliances, aerosol cans, etc.) combined with other steel scrap and then melted in a furnace to make new steel from old for new steel products. This enables the industry to utilize the closest smelter.
