VeharstGlas

The aim of the project VeharstGlas is to convert the residual materials from mining and smelting, i.e. slags and sands, but also residual materials from current recomine processing projects into glass and suitable glass products.

In concrete terms, two approaches are to be pursued:
A) Hydrothermal dissolution of the residual materials, or a water glass produced by adding alkalis, wet-chemical separation of remaining valuable elements, or harmful elements and production of a water glass solution (i.e. liquid water glass) for use e.g. as a binder (e.g. mineral paints), sealing material in the construction industry, but also of landfills or in underground mining or for foundry technology.
B) Utilization of the various residual materials and waste streams in combination for the preparation of alternative raw materials and additives for the production of glass fibers, e.g. for composite materials, fiber mats and glass fiber fabrics, e.g. for use as heat protection but also for insulation applications.
The complex residual materials are not only characterized and pre-treated, but by blending different residual materials, optimal recipes for glass production are created in order to improve the economic efficiency of production.
