Our initial idea to utilise the waste material sewage sludge as a resource has become reality: The sludge2energy plant in Straubing has operated successfully since its installation.

The demand for thermal sewage sludge utilisation is rising worldwide because landfilling and agricultural use of sewage sludge is not allowed any more or will soon be prohibited in more and more countries. The sludge2energy system is a cost-effective and sustainable solution which provides security of sewage sludge utilisation.

  • Sewage sludge is utilised in a decentralised system on site.
  • The energy contained within sewage sludge can be used for energy self-sufficient plant operation.
  • The ash from mono-incineration of sewage sludge is rich in phosphorus and therefore a good source for phosphorus recovery.

In cooperation with WTE in Essen HUBER have used their experience to develop the sludge2energy system as a turnkey solution for sewage sludge utilisation. The comprehensive expertise of both companies in the fields of sludge treatment, sewage sludge drying, incineration, and manufacture and operation of plants has been used to develop a cost-effective and reliable modular system which meets specific customer requirements.

The planned joint enterprise sludge2energy GmbH will be based in Berching. It will develop and implement customised solutions for sewage sludge utilisation and offer them on the global market.

The sluge2energy GmbH will provide engineering support, manufacture and operation of turnkey products and financing of sewage sludge utilisation plants.

The managing directors of the new sludge2energy GmbH will be Mr. Jörg Köring (WTW) and Mr. Harald Plank (HUBER SE). Both have gathered broad experience over many years in their mother companies and will for the first time represent their new company at the IFAT 2012 (hall A2, stand no. 333, and hall B1, stand no. 155).
