The waste to be treated is generated from household waste. The waste is crushed and screened in the customer’s mechanical treatment plant (MTP). The screen overflow > 80 mm is freed of ferrous and nonferrous metals by a ferrous and non-ferrous separator and is fed to a loading process as a fraction with a high calorific value (HCV). The iron is largely separated from the fine fraction < 80 mm by a ferrous separator. After that, the material is fed to the intensive composting system.
- The automatic input process piles up the material loosely and windrows it for the composting process optimally in the tunnels without any additional compaction by a wheel loader.
- Minimum power consumption for ventilation by open ventilation basements.
- Low cleaning expenses by small conical nozzle openings in the aeration floor and open ventilation basement.
- Operation of the intensive composting process without waste water possible; the process water from the input material leaves the system through exhaust-air cleaning.
- Pressurized ventilation ensures optimum aeration of the material and removes deposits in the ventilation nozzles.
- Good control of the process by small self-contained units in the tunnels.
