SusPhos One
Circular products
The SusPhos process begins with a phosphate-rich source, such as incinerated sewage sludge ash or meat and bone meal. Currently, the phosphate in sewage sludge ash is not recycled and discarded. Through our zero-waste technology, we recover over 80% of the phosphate while producing two fully circular products:
The SusPhos journey started in 2019, and after two years of successful lab experiments, pilot testing took place at the wastewater treatment plant in Leeuwarden. Now, we have tested our technology with various equipment suppliers, and while refining our process, we are entering the final stage, the full-scale implementation of SusPhos One. Years of testing and development have ensured that our technology is robust, reliable and ready for realising real-world impact.
Transforming existing wastewater facilities into urban mines is at the heart of what SusPhos does. By recovering valuable raw material from waste, we reduce the need for traditional, fossil-sourced materials, contributing to a more sustainable, circular economy. Our process not only supports greener agricultural practices but also creates products that strengthen the cement industry and other sectors, like fire retardants and feed phosphate.
