Products and services for municipalities and private companies

The companies and business units in THE PAULY GROUP have worked with a customer focus for many years.


Ecotechnological systems, sewage sludge humification plants as an example of an economical alternative to sewage treatment plants:

Today, over 1.2 million people in Germany and neighbouring countries are already benefiting from what will soon be 90 sewage sludge humification plants, all of which installed in full by our business unit EKO-PLANT as a main contractor. This makes us Europe’s uncontested market leader in this segment. Example: The sewage sludge humification plant run by the special-purpose association for water supply and wastewater disposal in Fürstenwalde and the surrounding area has 11 beds, making it one of the largest sewage sludge humification plants constructed in Germany. In 15 years, over a million cubic metres of sewage sludge have already been processed here.

Customers look back on their decision to install a sewage sludge humification plant:

“Like any municipality, we have to watch our budget. We have found a solution that is also a real alternative, ecologically speaking.”
(Tilo Küthe, Mayor of the Municipality of Helsa)

“Our duty of care to our customers means we are used to calculating the economic impact of our business ventures in great detail. With sewage sludge humification, we have found a system that benefits everyone.”
(Henning Stegie, then Director of the Ithbörde/Weserbergland Water Board)

“A lot has changed for the better since we started sewage sludge humification. Our work is now much easier and more economical thanks to dewatering without the use of energy. And we have also gained a great deal of independence and flexibility.”
(Mike Maurer, Treatment Plant Manager, Gudensberg-Maden)

“As a service provider for the people in my city, I need planning reliability and a low-cost strategy. EKO-PLANT gives me both of these things.”
(Frank Börner, Mayor of the City of Gudensberg)

And as this link shows, the city continues to enjoy the benefits of its plant today.

“Ecotechnological systems are a complex business. That’s what I find fascinating about them. To ensure we get the best experience, EKO-PLANT also offers a full range of services for plant operation and waste disposal. And all at our specific request, of course.”
(Tilo Küthe, Mayor of the Municipality of Helsa)


Ecotechnological plants, natural water parks as an economical and attractive alternative to conventional open-air swimming pools:

Since natural water parks guarantee that holiday feeling, the special surroundings offered by an EKO-PLANT – such as Brackwede – can attract up to 3,700 visitors on peak days.

Customer feedback on natural water parks:

“There’s not a drop of chlorine anywhere. This first-class water quality is provided by nature herself.”
(Peter Rausch, Chairman of the Brackwede Water Park Association)

“The open-air baths in Versmold had got pretty run-down. But no-one could imagine the town without an open-air swimming pool. What was needed was a smart piece of decision-making: acquiring a more modern, more appealing and cleaner pool but at an affordable price. And so the water park idea was born.”
(Thorsten Klute, Mayor of Versmold until 2013, on his decision to green light the natural water park at Versmold. Mr Klute is now State Secretary in the NRW State Government.)

(WGV Recycling Quarzbichl GmbH, special feature on Loisachtaler Erden, April 2012)

Feedback from attendees of HUMUS- UND ERDEN KONTOR practical workshops:

“The many practical demonstrations directly involving our own products meant that a lot of the workshop material has stayed very fresh this time. This gives customer advisors much more confidence when recommending the products. Thank you for a very interesting and well-organised workshop.” (Anna Brandhofer and Peter Kreitmeir, WGV Quarzbichl)

“My take-home for production and customer advisors: don’t throw all your effort into zero-peat products – be happy with our low peat content and advertise the major peat savings achieved. The practical exercises are great – more please!” 
(Stephan Margraf, Head of the Lohfelden Organic Composting and Digestion Plant, District of Kassel Waste Disposal)
