The aim of the IntenKS research project is to develop an ecologically and economically sustainable concept for the optimized material and energy recovery of sewage sludge.
The ISOE research team is coordinating the socio-economic evaluation of sewage sludge treatment and utilisation in China, based on a pilot site in Shanghai. Of special interest are existing practices for dealing with sewage sludge, and prevailing barriers to the implementation of innovations, along with the reasons for such barriers. The project adopts a transdisciplinary research approach. Expert interviews and workshops with Chinese and German stakeholders (e.g. operators, authorities, companies, science and development cooperation) will help identifying obstacles to innovation and developing options for action to overcome potential conflicts. Conclusions can then be drawn regarding a sustainable concept for improving sewage sludge treatment and utilisation.
Improper disposal of sewage sludge can release toxins and trigger infections, thus creating human health risks. An optimal treatment and utilisation of sewage sludge is particularly important in densely populated regions of China and with regard to sustainability. The aim is to improve the handling of sewage sludge whilst enabling its material and energetic utilisation.
The project “IntenKS – Intensivierung der Klärschlammbehandlung zur energetischen und stofflichen Nutzung in China unter Einsatz thermaler Verfahren” (“Improving sewage sludge treatment in China for energetic and material utilisation with the help of thermal procedures”) is funded within the “CLIENT II” funding directive “International Partnerships for Sustainable Innovations” as part of the framework programme “Research for Sustainable Development (FONA)” run by the German Federal Ministry of Education and Research (BMBF).
