Treatment of residual waste

Residual waste treatment

We don't make things easy for ourselves with the waste. 
Treatment and recycling are very popular.

The waste industry in balance

Sustainable waste disposal security:

  • Residual waste treatment plant with a capacity of 120,000 tonnes annually
    1. Treatment plant for light plastic shredding residues
    2. Residual waste treatment for
       -residential waste
       -commercial waste
       -mixed materials


Treatment process for light process shredding residues:

  • Separation of light plastic shredding residues into
    -Thermal value fraction
    -Sieved sand
    -Non-ferrous metals
    -Ferrous metals

Treatment process residual waste treatment:

  • Separation of mixed waste into individual materials:
    1. Alternative fuel source for generating heat
    2. Ferrous metals and non-ferrous metals
    3. Biogenic residual parts

With the concept behind our plants at our Ihlenberg facility, we meet the stringent demand to use natural raw material resources sparingly. This sees the secondary fuels created during the treatment process, and the removed materials being returned to the material and energy cycle. In this way, we make a valuable contribution to ensuring an environmentally-compatible disposal of waste in North-West Mecklenburg.

The residual waste treatment separates mixtures of waste into several different materials that can then be used as an alternative fuel source or reintroduced back into the production cycle as materials. This optimum material-specific treatment sees IAG meet its responsibilities with respect to people, the environment and a sparing use of resources.

What happens with the materials with a high thermal value?

  • Replacing fossil fuels such as coal, oil or gas
  • Use of replacement fuels in the cement and power industries, as well as in biomass power plants
  • Treatment of plastics, paper and packaging, as well as wood

What to do with the recycled raw materials?

  • Material recycling of plastics, paper and cardboard boxes
  • Return of ferrous and non-ferrous metals into the production cycle via smelting 


The processing steps for residual waste treatment can be summarised as follows:

  • Delivery of the residential and commercial wastes
  • Advance shredding in the shredder
  • Separation of the fractions of different sizes using sieves
  • Removal of ferrous materials using magnets
  • Removal of non-ferrous materials using eddy-flow separators
  • Near infrared separation of PVC and plastic films
Sprinkler system

Sprinkler system

We use state-of-the-art stationary integrated sprinkler technology from ROSENBAUER/Orglmeister.
Since July 2015, a foam-extinguisher system in our residual waste treatment plant (RABA) in combination with an infrared temperature monitoring ensure the highest levels of safety and security against fire.
This new technology, in particular, protects the section of the RABA where the waste is delivered to: the building where deliveries are taken in, as well as the machine technology in the waste treatment plant. The sprinkler system offers permanent monitoring and, in the event of an emergency, it starts the extinguishing process automatically long before the fire breaks out.

Mode of action

If the infrared monitoring detects a significant temperature increase, the coordinates of this “hot spot” are sent to the thrower. The extinguisher liquid pump turns on and conveys a mixture of water and foam to the thrower via permanently operational pipelines. The thrower directs the water-foam-mix towards the detected hot spot all on its own and quickly and reliably begins with the fire extinguishing.

The infrared monitoring recognises hot spots very quickly. Traditional fire protection plants often react only when a certain temperature has been reached or when smoke has been detected at ceiling height. The ROSENBAUER/Orglmeister system in contrast, recognises dangerous situations a lot earlier and so is able to very significantly reduce the risk of fire.
Another advantage: By using the water-foam-mix, the hot spots are particularly well covered and cooled, while the oxygen is cut-off from the flammable materials at the same time. Relatively little extinguisher liquid is required for this.

PREVENTION in fire protection is worth it! The safety and continuity of the plant operations are worth it for us.

Disposal is a matter of trust.
