Interesting Facts: GLASS In Florida, pulverized recycled glass from clear bottles, cups, windows, and other glass products is now being used as a sand substitute to counteract the beach erosion in Florida. Glass is originally made of sand, thus the recycled glass is returning to its natural place in nature Previous sand dredging to fill the beaches included about 13 million tons since 1970. That's enough sand to fill the Empire State Building more than 12 times over. Using granulated glass instead prevents further sand dredging and thus protects future marine habitats – UH Sustainability Beaches on Lake Hood in New Zealand and on the Dutch Caribbean island of Curacao already use recycled glass to combat erosion – UH Sustainability Recycling one glass jar saves enough electricity to run a 60-watt light bulb for four hours or an 11-watt compact fluorescent bulb for 20 hours. It also causes 20% less air pollution and 50% less water pollution than when a new bottle is made from raw materials – National Recycling Coalition A modern glass bottle would take 4000 years or more to decompose -- and even longer if it's in the landfill. Recycle it, and it can be recycled an indefinite number of times and never wears out – National Recycling Coalition Mining and transporting raw materials for glass produces about 385 pounds of waste for every ton of glass that is made. If recycled glass is substituted for half of the raw materials, the waste is cut by more than 80% - Recycling-revolution.com
