Verification and implementation of new technology for reycling of lead glass

40 sites in the Kingdom of Crystal will be excavated. If the glass is re-cycled, we remove impurities from nature and decreases the need for virgin raw materials. We will verify an industrial scale method to recycle lead glass waste from landfill sites and investigate how to implement this in the ongoing remediation of the Kingdom of Crystal.

Melting where glass and metalls are separated

In the Kingdom of Crystal in Southern Sweden there are more than 40 glasswork sites which are classified as very high risk. These should be excavated sooner or later. In the previous project Glass deposites from waste to resource we have shown that it is possible to separate lead and glass in small scale. In our new project we will verify an industrial scale method to recycle lead glass waste from landfill sites and investigate how to best implement this in the ongoing remediation of the Kingdom of Crystal. This requires:

  • Identification of lead glass hot spots.
  • Excavation and sorting methods separating glass from other waste into different glass qualities.
  • Melt-separation matrix parameters and scale-up factors.
  • Industrial scale waste lead glass melt separation method.
  • Demonstration of products made of recovered glass
  • Organization for implementation

Verifying the methods in full scale will make it possible for public and industrial actors to invest in a melt-separation plant and returning the landfill glass to the circular economy which is the working method of a sustainable society. Also lead and arsenic will be possible to recover and reuse instead of mining the minerals.

The broad consortium thus contains all necessary parts, problem owners, research institute, glass melting facility, waste management and design of possible products. We are financed by SGI, both the Country Administrative Boards and in-kind from the industrial partners.
