Sludge utilisation


Sewage sludge incineration 

For phosphorus recovery from ash sewage sludge may only be treated in mono incineration plants.

Thermal mineralisation of sewage sludge in the PYREG®

By pyrolysis sewage sludge is being mineralised and reduced in its amount. Mineralisation of sewage sludge takes place below the ash melting temperature of 800°C. Hence, phosphorus in the so-called biochar becomes plant available. The suitability of sewage sludge derived biochar as fertiliser is currently being investigated.

This process is suitable for plants with a population equivalent of more than 30’000. We are happy to consult you in selecting the optimum process.




We adopt processes according to your project requirements and achieve optimal solutions using selected products from proven suppliers.
