Manufactured sand production

At Metso, we have developed a unique industrial process to reduce the amount of cement needed in the concrete mix. An unbiased study done in Norway in 2015 verifies that the amount of cement can be decreased by up to 15% when using Metso’s highly advanced manufactured sand solution instead of local natural sand.

Sand to Soda Bottle, An Overview of the Glass Manufacturing

Along with these raw materials, recycled and ground glass, known as cullet, is also added into the mix. Cullet generally comes from municipal recycle programs or from the production scrap from the manufacturing process. Recycling glass reduces in-house waste and helps to augment the supply of cullet necessary for manufacturing glass bottles.
