Decentralised Integrated Sludge Management (DISM)

2015 - 2019 • Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH


To put in place an integrated approach for the treatment and reuse of sludge, in order to tackle the problems of sludge collected in wastewater treatment plants and to contribute to reducing CO2 emissions.


On behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ), GIZ is supporting the Water Authority of Jordan in its efforts to find suitable solutions for the treatment and reuse of sewage sludge. The project aims to reduce the carbon footprint of the sludge handling process. To this end, it considers the use of sludge primarily as a source of energy, but also as a soil conditioner and a fertiliser. The project also seeks to demonstrate an integrated approach to the treatment and reuse of sludge in combination with other biomass sources (co-digestion). After the energy potential of the sludge has been tapped, any residual sludge undergoes further processing, together with other sources of biomass, to produce a treated organic mix that can be used to improve soil quality.

The integrated approach ensures the involvement of all significant stakeholders, from the relevant ministries and municipalities, to the water utilities and farmers. The project also includes close scientific cooperation with Mutah University located close to the Mutah-Mazar demonstration plant in the Governorate of Karak.

The project is part of the German Climate Technology Initiative (DKTI), which promotes the take-up of climate technologies in emerging economies and developing countries, thereby linking climate protection, sustainable development and poverty reduction. The initiative promotes the transition to a low-carbon economy and contributes to efforts to achieve the two-degree climate goal. It also focuses on mobilising economic potentials for climate technologies.
