What is IMRG?

The patented IMRG-Technology is an autothermic 5-steps gasification process followed by a thermal gas treatment with plasma conditioning.

The resulting heat is reused in the process to preheat the gas streams that support the gasification process.

The resulting syngas is a clean low caloric fuel gas, that can be directly utilized in gas engines. The slag is inert.

5-step Process

Input / Feeding

Recuperative drying

Pyrolysis

High-temperature gasification

Slag inertisation

Inputs

As feedstock IMRG Technology can use all caloric resources from all input materials:

  • unsorted municipal waste
  • industrial waste (e. g. car tyres and residuals from recycling and production)
  • agricultural residuals and biomass
  • hazardous waste.

Results

After the 5-step IMRG process is finished, the results are:

  • synthetic gas – derived from the organic components
  • slag – derived from the inorganic components
  • process water – result of water content from the input and
  • recycled metals – from the metal waste in the input.
