Project: Closing nutrient cycles from municipal and industrial waste water (KNAP)

Intended result

Next to a diversity of cases in which on central and decentral level nutrients are recovered from municipal and industrial waste water, and are being reused, the project is aiming for the delivery of the following items:

• The core is a developed quality system for recycled products and fertilizers from municipal and industrial wastewater.
• Furthermore, a current insight into the largest leaks of macronutrients from the Dutch nutrient system.
• Detailed information on the agricultural value, quality, and safety of the individual recycled fertilizers from the various cases.
• And by the end of the project, we want to have a clear understanding of the existing barriers in legislation and regulations that hinder the optimal valorization of nutrient-rich residual streams and also suggest solutions for these.

It is crucial that there a broad support is developed at the government, companies and knowledge institutes for the developed quality management system and for the realisation of the cases after the research project has been finished.
