Method & Evidence

AimTo investigate and develop a process for upgrading crude pyrolytic tyre char to improve its market value and sustainability.
MethodExperimental research and process development
ProcedureThe study involved literature research to identify upgrading methods, followed by experimental characterization of industrial tyre char and a target carbon black product (N330). An acid-alkali leaching process was then developed and applied to the char, with subsequent analysis of the upgraded material's properties (ash content, surface area, particle size). Economic viability was also assessed.
ContextWaste tyre recycling and material processing

Variables

IVAcid-alkali treatment process
DVAsh content, BET surface area, average particle size
CVType of pyrolytic tyre char, concentration of acids/alkalis, treatment duration, temperature

Strengths & Limitations

Strengths

  • +Addresses a significant environmental issue (waste tyres).
  • +Provides a clear, experimental methodology for material upgrading.
  • +Includes economic evaluation, adding practical relevance.

Limitations

The cost of chemicals and energy for the treatment process, as well as the disposal of any by-products from the treatment itself, need to be considered.

Reliability & validity

The study's reliability would be enhanced by repeating the experiments multiple times and ensuring consistent measurement techniques. Validity is supported by comparing results against established benchmarks for carbon black.

Think critically

What are the potential environmental impacts of the acid-alkali treatment process itself, and how can these be mitigated?

05

Design Principles

"Waste streams can be transformed into valuable resources through targeted processing."

This process transforms a waste product into a potentially valuable material, addressing environmental concerns associated with waste tyres and opening new market opportunities for recycled carbon black.
