Plastic Recycling Pyrolyse

PLASTIC Waste

We start from where materials recycling has reached its limits...

Input materials:

Post-consumer as well as post-industrial products

70-80% of the input is converted to high-calorific pyrolysis gas (virtually the calorific value of natural gas)

Pyrolysis coke, depending on the feedstock

Recycling, e.g. carbon black from master batches

dry, mostly fine-grained and medium-calorific waste material that can be used as a substitute fuel by cement industry.

Benefit:

"In-house" thermal utilization concept for reduction of volumes and energy supply (co-generation)

Input

Input

  • Post-consumer waste
  • Post-industrial waste

PYROLYSIS

Output

Pyrolysis Gas

  • High-calorific Gas
  • Use of heat directly (e.g. process heat or steam) or electricity generation

Pyro-coke

  • Significant mass and volume reduction
  • Good fractionability (grain size, metal / non-metal, etc.)
  • Possibly further usability

 

Case examples:

The flood of plastic waste, coming from production or after use in the classic "yellow bag", is increasing from year to year. The material utilization by mechanical/thermal processing and further re-pelletization make a valuable contribution to the material cycle. However, the amount of freight that is no longer recyclable will also increase, either through ever more complex composite structures (e.g. film laminates) or plastic compounds that are no longer recyclable.

From this perspective, pyrolysis allows the waste to be recycled into high-calorific pyrolysis gas (with a calorific value of approx. 80% of natural gas) or a coke fraction, which could be converted, as in the case of PET master batch waste (with 30% carbon black filling), into carbon black recycled material (r- CB).

The benefit of the T:CRACKER unit is its ability to provide a customized solution to meet the volume and requirements of the customer. The thermal energy of the pyrolysis gas can be used for process heat, electricity generation or other applications. The solid precipitate in the form of pyrolysis coke decreases by about 70-80%. Depending on the quality of the input, this can be used as a valuable material or, in the worst case, as a dry and readily dosable fuel in garbage incineration or cement works.
