Doesn’t recycling metals take a lot of energy to melt and re-mold them? Is it worth it?

    Although it seems like melting down and re-shaping recycled metal products would take a lot of energy, the process actually consumes far less energy than making metal out of raw materials. In fact some metals, such as aluminum, give you the largest energy savings of almost any material when they are recycled. Recycling an aluminum can takes just 5% of the energy that would be needed to make a new can from scratch, and produces 5% of the greenhouse gas emissions as well. Other metal products are also highly beneficial to recycle; for instance, recycling one steel can saves enough energy to power a 60-watt light bulb for more than a day. Recycling metal is definitely well worth the effort.
