Glass is an essential material in many industries, including construction, packaging, and transportation. It is a versatile material that is durable, transparent, and easy to clean. Glass can be made from either virgin or recycled materials, but what are the differences between the two? In this blog post, we will offer a fact-based, unbiased comparison of recycled glass vs. virgin glass.
Recycled Glass
Recycled glass is created by melting down used glass and reforming it into new products. By using recycled glass, we can reduce the amount of waste that ends up in landfills, conserve natural resources, and reduce our carbon footprint. Recycling one ton of glass saves 670 pounds of CO2 emissions, and for every ton of recycled glass used, we save 1.2 tons of raw materials as well as 1,300 pounds of sand, soda ash, and limestone.
According to the Container Recycling Institute, recycling glass saves five gallons of landfill space per cubic yard of recycled glass, and for every six tons of recycled container glass used, there is a reduction of one ton of carbon emissions. Recycled glass can be used to create new glass containers or as an aggregate in construction projects.
Virgin Glass
Virgin glass is made from raw materials such as sand, soda ash, and limestone. These materials are heated to high temperatures to create molten glass, which is then formed into products. While virgin glass is an abundant natural resource, the production process requires a significant amount of energy and generates greenhouse gas emissions.
According to the Glass Packaging Institute, manufacturing virgin glass containers emits 3.3 pounds of CO2 for every pound of glass produced. Moreover, the production of virgin glass uses approximately 50% more energy than producing recycled glass.
Recycled Glass vs. Virgin Glass: Comparing Costs
The cost of recycled glass is generally less expensive than virgin glass due to a lower cost of raw materials and reduced energy usage.
In 2021, the average cost of recycled glass cullet (sorted and crushed glass ready for melting) in the US was between $20-$22 per ton. In contrast, the price of virgin glass bottles was $45-$50 per ton. The cost of energy consumption is also higher for virgin glass since producing it requires much more energy than recycled glass.
Conclusion: Recycled Glass is the Clear Winner
In conclusion, recycled glass is the clear winner when it comes to sustainable, environmentally-friendly glass production. It reduces waste, conserves natural resources, and requires less energy to produce than virgin glass. Using recycled glass also helps to reduce carbon emissions and greenhouse gases.
Recycling glass is a win-win for the environment; it reduces waste in landfills while providing raw materials for new products. By choosing to use recycled glass, we can all play a part in creating a better, more sustainable future.
