Funding for the operation financed by a public-private partnership between the city of Poznan and a joint venture set up by SUEZ and the Marguerite Fund, the European Fund for Energy, Climate Change and Infrastructure

Predictable household waste treatment costs and a saving of approximately 20% compared with landfill Economic

Reuse of soil decontaminated through bioremediation at the site: reduction of about 30% in processing, transport and elimination costs relative to a conventional solution


Electricity generation equivalent to the consumption of 120,000 residents

Over 40% of the electricity generated is recognised as renewable with green certificates

5% of the city s energy needs for urban heating

100% of bottom ashes recovered for road building


1.4 million tonnes of soil decontaminated, 98% reused at the site

Minimisation of the road transport associated in conventional decontamination operations, which transfer polluted soil to off-site processing installations and bring in soil from outside

Controlling and reducing the negative effects for people nearby (odours, dust)

Poznan (Poland) To reduce the quantity of waste sent to landfill and meet the population s growing need for electricity, the city of Poznan commissioned SUEZ to build a waste-to-energy plant for non-recyclable waste and operate it for 25 years. Opened in 2016, the plant processes over 210,000 tonnes of waste a year for the benefit of 730,000 residents.

Tertre (Belgium) Rehabilitation of the former site of Belgium s largest coking plant. The public interest organisation SPAQuE, commissioned by the Walloon region to rehabilitate brownfield sites, contracted SUEZ to decontaminate the soil at the site of the former Carcoke plant, which is to become an eco-zone covering nearly 40 hectares. The choice of the bioremediation technique, which involves creating the optimum conditions for contaminants to be broken down by micro-organisms already present in the soil, helped reduce the cost of the site s rehabilitation and minimise its environmental impact.


Contribution to the Walloon region s sustainable development objectives: creation of a business park and a solar farm


The installation is regularly opened to the public, and has already been visited by over 4,000 people to understand its role in the waste management system
