Recycled glass is made from used glass products that are collected, cleaned, and processed to create new glass items. This process helps reduce waste in landfills and conserves natural resources, as it requires less energy compared to producing new glass from raw materials like sand and soda ash. The recycling of glass is beneficial for the environment, as it lowers greenhouse gas emissions and reduces the need for mining. Common products made from recycled glass include bottles, jars, and even construction materials like glassphalt, which is used in road paving.
