REMONDIS takes over IAA in East Westphalia-Lippe

Takeover expands the business field of sewage sludge recycling in the region of East Westphalia-Lippe

REMONDIS Aqua Stoffstrom GmbH & Co. KG acquires 100% of the shares in IAA Ingenieurgesellschaft für Abfall und Abwasser mbH & Co. KG, which is based in Kalletal, Germany.

IAA has been active in the field of recycling and disposal of municipal sewage sludge and infrastructure waste for more than 30 years and has established itself over this period as a leading company both in the region of East Westphalia-Lippe and in Lower Saxony. The total of five locations in the region of East Westphalia-Lippe make it possible to offer municipal customers tailor-made services for all aspects of safe and sustainable sewage sludge utilisation. The sale was made against the background of entrepreneurial succession with the aim of securing and expanding the IAA.

Managing Director of REMONDIS Aqua Stoffstrom GmbH & Co. KG, Ralf Czarnecki, is extremely pleased about the takeover of IAA: “With IAA, we can rely on a recognised and established company in the region. We would like to thank them for the trust they have placed in us and are pleased to be able to expand our business field of sewage sludge utilisation in the region.

As one of the leading companies in the field of sewage sludge recycling, REMONDIS Aqua Stoffstrom GmbH & Co. KG, based in Mülheim an der Ruhr, is already active throughout Germany with a wide range of services. The company offers solutions for all aspects of sewage sludge recycling that meet the growing legal requirements for climate protection and resource conservation.

Phosphorus recovery

One example of securing raw materials from wastewater is the recovery of phosphorus contained in sewage sludge. As one of the elementary building blocks for plant and animal life, the finite resource phosphorus is considered a critical raw material whose deposits will be depleted in about 150 years according to calculations by various geological institutes. The German federal government has also recognised this and has prescribed by law that phosphorus must be recovered from municipal sewage sludge and returned to the economic cycle from 2029 onwards.

With REMONDIS’ TetraPhos®, this is already economically feasible today and is already being implemented in the world’s first large-scale phosphorus recycling plant in Hamburg, Germany. The electrical and thermal energy required for the entire recycling plant is largely generated from the integrated energy recovery of the sewage sludge. The recycling plant can thus be supplied with CO2-neutral energy. Overall, the plant saves 60 % CO2 in the production of phosphorus in the form of phosphoric acid compared to imported raw material from primary sources.

This phosphorus recovery process will also enable IAA’s customers to be offered “an extended value chain in the future”, says Christoph Tritt, former owner of IAA. He is also pleased that the company is in the hands of a trusting family business.
