Glass Recycling

The secondary raw material glass: a never ending story Aside from the primary resources, recycled waste glass plays an important role in producing glass. Today, waste glass is the most crucial component of new glass containers and its recycling process can be continued indefinitely. Therefore glass is a hundred percent recyclable. Used glass, in combination of collection and treatment, is part of an infinite circuit and can be turned into new glass again and again. Regarding container glass, cullet can even replace sand as the main component.            http://www.bvglas.de/der-werkstoff/glasbestandteile/ Glass – a clear thing! Currently, approximately 2 million tons of waste glass are collected annually in Germany. This means that every German citizen collects and disposes of about 24 kg waste glass. The recycling rate is ca. 81% which places Germany among Europe's front-runners. Through our high-performance glass recycling, we want to support the needs of both the people and the economy – that is to actively contribute to our environment. Glass – a very special raw material! While other materials, such as plastics and paper, have to endure quality losses during the recycling process, glass is entirely recyclable. The raw material glass has gained great importance in producing container glass: On the one hand, natural resources are conserved. 7 m³ of rocks have to be mined for 1m³ of the primary raw material. By using recycled glass cullet the demand for primary resources is thus reduced and nature can be preserved. Furthermore, the energy consumption per 10% cullet use is reduced by 3% in the melting process. Using 60 – 90% secondary glass in the container glass production means that an energy saving of 18 – 27% can be achieved as well as the reduction of CO² gases. Especially in today's world where energy costs constantly increase, recycling glass becomes an essential criterion for the glass production in this context. However, the glass industry demands high quality standards of the secondary material. To avoid damage in the glass production, only waste glass that is nearly color pure and free of impurities such as metals, ceramics, rocks and porcelain can be used in the furnace. By constantly adapting and modernizing our treatment technology, we align ourselves with our customers' wishes and requests. We create a homogeneous product out of inhomogeneous input material. Glass – one raw material: many possibilities! Waste glass cullet is found in the flat glass and specialty glass industry, as well. Here, production waste that incurs during the original production process is used amongst others. In addition, specially treated high-quality glass granulate from treatment plants, e.g. the GRI, is taken into the process. Up to 20% waste glass is used in producing flat glass.
