Problem description:

The current efforts in industry aim to reduce the carbon footprint. One of the strategies is to reuse waste, or use the secondary raw materials separated from waste.

Well-aware of the secondary raw material separation problems, Jan Nečas’s team from VŠB-TUO focused on improved separation of raw materials from bulk mixed waste (e.g. crushed electric cables). To be able to use the mixed waste as secondary raw materials, maximum separation and maximum purity of the discrete constituents are needed (metal, plastics, etc.)

Technology description:

The developed technology is able to achieve a high level of purity of the different waste constituents because of using multi-phase fluid separation placed in a modular system. The modular system makes it possible that requirements for different types of separated constituents are met, but it also eliminates contamination of the separated material in the process of own separation.

Thanks to the special construction, the level of waste separation effectiveness reaches 90 % and the process is low in energy intensity. The future commercial partner will acquire a technology with a high added value which moves the competitiveness to a new level.
