Environmentalist: It takes less energy to make molten glass from recycled glass than from raw materials  Once the recycled glass or raw materials have been turned into molten glass, making bottles from recycled glass follows the same process as making bottles from raw materials  Obviously, soft drink bottlers who make a large percentage of their bottles from recycled glass have significant energy savings
Ttherefore, by using recycled glass instead of glass made from raw materials, bottlers can lower their costs and benefit the environment at the same time
Purchasing and transport costs are not so much greater for recycled glass than for raw materials that they outweigh the savings in energy costs resulting from the use of recycled glass.
