Reference flow in the MFA for which is suitable the technology

Waste tyres (160103) and unvulcanized & vulcanized rubber

Incoming input

Organic (carbon-based) waste (and maybe oxygen/inert gas).

Outgoing output

Gases that contain CH4, H2, CO, CO2, H2S, SO2 and other hydrocarbons; char; tar oil which is a liquid product (that could be used as a fuel, in pharmaceuticals etc.)

Technology description

Pyrolysis is equal to heat degradation. In this treatment material is exposed to high temperature, and in the absence of oxygen goes through chemical and physical separation into different molecules.

Organizative processes to support closing the loops

Government's support is necessary since it is a really expensive technology.

Practitioners opinion

After pyrolysis the quality of carbon black is not steady. It is problem, because it is hard to recycle/reuse it. Plus the cost is high. So many cases it is either stored or disposed.

Possible limiting factors

Cost and energy need could be limiting factor + the capacity and the scale is also an important question. In Hungary only a limited amount could be treated this way. As a general solution, some more will be created the citizens’ support and acceptance is necessary, but they afraid of this technology – NIMBY effect is high. How the end products could be used?

PP’s opinion of the technology

No data available.

Concept and conclusions how the technology can affect the CE effect

Pyrolysis means 100% recycling of tyres, all high valuable raw materials are extracted smoothly. It harvest 4 "green" products: carbon black, steel, oil and high calorific combustible gas which can be used for generating electrical energy, heat, steam or hydrogen. But bigger pyrolysis plant is needed which is expensive and people are afraid of this technology.

Is the technology a BAT?

No data available. We do not have and know the exact industrial-scale technology solution.
