Energy Implications of Glass-Container Recycling

Energy Implications of Glass-Container Recycling by L.L. Gaines and M.M. Mintz Abstract This report addresses the question of whether glass-container recycling actually saves energy. Glass-container production in 1991 was 107 tons, with cullet making up about 30% of the input to manufacture. Two-thirds of the cullet is

How does recycling save energy? | American Geosciences

The largest energy savings achieved by recycling are generally for metals, which are often easy to recycle and otherwise typically need to be produced by energy-intensive mining and processing of ore. For example, energy savings from beryllium recycling are 80%, 5 lead 75%, 9 iron and steel 72%, 9 and cadmium 50%. 10
