Waste tyre pyrolysis equipment

Waste tyre pyrolysis plant

Waste tyres are thermally decomposed in a sealed, controlled, oxygen-free system to form condensable vapour, non-condensable process gas, carbonaceous solids and steel. RUNDA configures pretreatment, feeding, reaction, condensation, gas handling, discharge, steel separation and controls around the tyre type, feedstock form, stable supply, operating mode, site and target outputs.

Published models and values are references for early comparison. Final capacity, weight, power, shipment and configuration remain subject to confirmed technical documents.

A complete line from tyre reception to recovery of oil, carbonaceous solids and steel

  • After waste tyres enter the sealed reaction system, their polymers are thermally decomposed under oxygen-free conditions into oil vapour, carbonaceous solids and non-condensable process gas. Tyre steel is recovered after discharge, while the vapour is separated and condensed in stages to form pyrolysis oil.
  • After purification, pressure stabilization and safety control, non-condensable process gas may be assessed for reuse as system fuel. Carbonaceous solids are cooled in a closed system, sampled and tested before a downstream route is selected according to ash, volatile matter, particle size, metals and buyer requirements.

Main outputs

  • Pyrolysis oil

    A condensed liquid product whose actual use depends on testing, local standards and buyer requirements.

  • Carbonaceous solids

    After closed cooling, sampling and testing, assess grinding, pelletizing or further material upgrading against ash, volatile matter, particle size, metals and downstream requirements.

  • Steel

    Metal recovered from the tyre carcass during discharge and magnetic separation.

  • Non-condensable process gas

    After purification, pressure stabilization and safety control, it may be assessed for system heating and must not be released as a fugitive emission.

Frequently asked questions

  • Can whole and shredded tyres use the same feeding system?

    Not always. Feeding depends on tyre size, capacity, site, labour and existing shredding equipment.

  • What normally forms a complete tyre-pyrolysis line?

    In addition to the reactor: feeding, heating, vapour transfer, separation, condensation, gas handling, cooling discharge, steel recovery, storage, electrical and controls.

  • Can oil, carbon black and steel be sold directly?

    They require sampling, testing and confirmation against local law, standards and buyer requirements.

Selection basis

Tyre form, operating mode and downstream requirements define the line

Whole-tyre feeding, cutting and debeading, batch or continuous operation, and downstream carbon and steel handling all change the equipment scope. Compare the complete material chain rather than reactor dimensions alone.

Feedstock form

Record passenger, truck and OTR tyre shares and whether material arrives whole, cut or shredded.

Supply and pretreatment

Use tyre size, stable quantity, site and labour conditions to define cutting, debeading, shredding and storage.

Operating organization

Compare batch, semi-continuous and continuous routes using shifts, annual hours, planned stops and maintenance capability.

Output routes

Confirm testing and downstream acceptance for oil, carbonaceous solids, steel and non-condensable gas.
