Closed loops for clear waters: Innovative sludge management solutions for a toxin free environment

Time: 15:00-15:50 Wednesday 9 November

Venue: Lindgrenrummet

The success of circular economy depends on recycled materials, free of hazardous substances. The seminar discusses how the circular economy approach supports the work to reduce the impacts of hazardous substances in our societies. It will present a number of smart innovative solutions helping to reduce spreading of hazardous substances to the environment.
 
Moderator: Dmitry Frank-Kamenetsky, Professional Secretary, Helcom Secretariat

Presentations and panelists:
  • Sludge management solutions in the Baltic States.
    Mr Taavo Tenno, University of Tartu
  • Sludge Management in Finland – aims and new initiatives
    Mr Ari Kangas, Ministerial adviser, wastewater & sewage sludge expert, Finnish Ministry for the Environment
  • Amendment of the German sludge management act
    Dr. Claus-Gerhard Bergs, Head of Division Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety, Germany
  • From prototype to reality – how to up-scale innovation in sludge handling
    Anders Kihl, Head of research, Ragn-Sells, Sweden
There is a great potential in nutrient recycling from wastewater sludge to close the resource loop in industrial symbiosis where one industry's by-product becomes another industry's raw material. However, there is a risk to also increase the spreading of hazardous substances to the environment.
 
The use of chemicals in the society is increasing in both volume and complexity, many ending up in the wastewater sludge. Preventive measures such as regulating the use of hazardous substances are prioritized. However, impacts and change are made only very slowly and thus need to be completed with other solutions.
 
The seminar will present and discuss solutions for sustainable sludge management, aiming to turn todays waste into cleaner products, helping to minimize emissions of toxic compounds to the aquatic environment while achieving recycling of nutrients in a truly circular system.
What techniques are available today? How to foster and up-scale innovation? What can and should policy do?
 
The seminar will be starting off by presenting different solutions in sludge management as used in the Baltic States today.  
Representatives from Finland will update on the latest policy developments in the field of sludge handling in their countries.  
Ragn-Sells will give a short insight in their innovation work in the future of sludge handling in Sweden.
 
In a panel debate we will be elaborate on the need for innovation investments and support as well as the role of policymaking in realizing sustainable sludge management and nutrient recycling while ensuring a toxin free environment. Furthermore, we will elaborate on the potential and challenges that the concepts of industrial symbiosis and circular economy have for the creation of truly closed loops in our societies.
