Glass
Glass is made of soda ash, limestone and a lot of sand. The mixture is put into a very hot furnace and when it melts, it turns into glass.
It will take over 1,000,000 (one million) years for a glass bottle or jar to decompose (break down and disappear) when it goes to a landfill or dump.
Glass can be recycled into new bottles and jars, fiberglass insulation, concrete, sewer pipes, bricks, tiles, used as road paving materials, light bulbs, glassware, new glass containers, decorative home décor, surf boards (by way of fiberglass), and more.
Glass can be recycled and used over and over again. Most bottles and jars are made from recycled glass.
Recycled glass melts at a lower temperature than new materials, so it takes less energy to heat the furnace. Recycling one glass jar saves enough energy to light a 100 watt light bulb for 4 hours. By using 50% recycled glass in making new glass, water use is cut by 50%, waste is cut by 79%, and air pollutants by 14%.
