BitKOIN - CO2-reduced binders through thermochemical conversion of residue combinations containing mineral wool waste

Project: Research project

Project Details

Description

In the BitKOIN project, two technology concepts are being combined to develop a "granulated blast furnace slag 2.0" and the functional proof of this combination is being provided at system level. This takes into account two different market requirements: the waste management industry expects the development of a recycling path for mineral wool waste by 01.01.2027. The binder industry expects a replacement for blast furnace slag, which will no longer be produced in the future due to the decarbonization of the iron and steel industry and the associated phase-out of the blast furnace route, and requires quantities for this that exceed the annual volume of mineral wool waste (approx. 30,000 t in Austria). They can therefore only be achieved through a combination of residual materials. The project contributes to the strategic goals of the Austrian circular economy strategy in that, despite the elimination of traditional granulated blast furnace slag, larger quantities of primary raw materials do not have to be used for the future production of binders. Instead, mineral wool waste is deposited in combination with other residual materials, thus saving landfill volume. Overall, this has a positive effect on the climate and the environment, contributes to the security of supply of the Austrian binder industry even without granulated blast furnace slag, and establishes an Austrian network for closing mineral material cycles by building up knowledge and cooperation.
