Method and Device for processing of filter material, product obtained thereof WO2017122182

• The market for air filters made of non-woven fabrics and the market for activated carbon have been

growing exponentially for a long time and have reached a turnover of tens of billions of euros per year

• The technology helps to reduce the need for primary carbon commodity, thereby limiting the pressure on

monoculture plantations and reducing the emissions associated with its production

• The resulting products are intended for use in building and construction industry, conventional industry,

automotive, acoustic and hygiene applications, but also for filter manufacturers or waste recycling centers

What is created:

• Insulation material with excellent thermal, acoustic, antivibration and hygienic properties: non-

absorbent, antibacterial, anti-allergic, with zero mold growth, absorbs odors and dust

• Granulated activated carbon that can be reused in filters or in other industries

• A closed cycle where the waste is used to reborn of a new raw materials with higher value added.

Why to invest?

• Territorial validity of patents: EU, USA, China, India, Mexico, Great Britain…

• The patent covers the method, the proven technology and the product – high competitiveness.

• Two products for sale from one input = attractive business model

• The solution is easily scalable and adaptable (stationary or mobile units directly at the waste source)

• Significant ESG dimension: waste recycling, lower carbon footprint, support for circular economy

The technology described in patent WO 2017/122182 A1 processes the filtration material in an energy-

efficient aerobic mechanical process, without heat, using a rotary disintegrator. The flat filter substrate is

defibered into its original, predominantly hollow fibers during a defined retention time through repeated

contact with the rotating elements and the profiled inner surface of the disintegrator chamber. A swirling

airflow is created, forming aerated fiber clumps while simultaneously releasing the activated carbon—part

of which is separated for further recovery, and part of which is redistributed across the surface of the fibers,

significantly improving the thermal-technical and hygienic properties of the insulation material.

The key difference compared to the existing state of the art lies in the synergy of defibration, aeration, and

simultaneous carbon separation at low energy demand, without thermal or chemical degradation. This

preserves the original physical properties of the fibers while also recycling valuable activated carbon.

Compared to traditional approaches, our solution achieves higher product utility value and lower energy consumption of the process.
