Glass is an inorganic solid material that is usually clear or translucent with different colors. It is hard, brittle, and stands up to the effects of wind, rain or sun. Glass has been used for various kinds of bottles and utensils, mirrors, windows and more. It is thought to have been first created around 3000 BC, during the bronze age. Egyptian glass beads date back to about 2500 BC.History of Glass

Glass is collected from our homes by recycling lorries or from recycling banks by your local council. The glass is transported to the processing plant where it is washed and any rubbish, such as plastic, is removed. The glass is crushed into cullet (small pieces) and is transported to the glass factory. At the glass factory, the cullet is melted in a large furnace and then molded to make new bottles and jars.How is Glass Recycled?
•Glass bottles and jars come in three main colors: clear, green and brown.• The glass is often sorted by color, keeping the clear, brown and green glassseparate.• If the glass colors are mixed, it lowers the value and quality of the material.
Making new glass from recycled glass uses much less energy and reduces C02 (carbon dioxide) emissions. Recycling glass saves raw materials from being quarried and then thrown away in rubbish dumps, saving hundreds of thousands of tones of quarrying each year and conserving the countryside. Each time a tone of glass is made from recycled glass, 1.2 tones of raw are saved. Jobs are created by glass collection schemes, and also at recycling centers, which smash and clean recycled glass. By weight, glass makes up about 8% of our rubbish. Glass recycling reduces the cost of collecting and the disposing of glass mixed in with our rubbish. Glass can take 1 million years to break down in a landfill.Why should we recycle glass?
