SusPhos One

The first state-of-the-art
phosphate recycling factory

In 2027, the first full-scale plant based on SusPhos’s groundbreaking technology will be realised in Moerdijk, the Netherlands. Strategically located next to SNB, Europe’s largest sewage sludge incineration plant, the SusPhos One facility will set new standards for circular phosphate management. This pioneering plant, constructed and operated by S&S Feniks, the joint-venture of SNB and SusPhos, will serve as a beacon for urban mining, transforming waste into high-value products.

Circular products

Why SusPhos?

We don’t just recycle — we upcycle. Every element of the ash is transformed into a valuable resource, contributing to a zero-waste process. At SusPhos, we’re closing the phosphate loop, turning linear waste streams into circular value chains.

Our Technology

How it works

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:

Our technology is highly efficient, with minimal energy and water consumption, capable of processing 40 kton of ash annually. Another benefit is the small plot space (approx. 2.000 m²), which makes it possible to realise the plant back-to-back on the site of the incinerator.

Proven technology,
ready for full-scale

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.

Urban mining

The future is phosphate recovery

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.

For years, SNB has been working to find a way to recover phosphate out of our sewage sludge ashes. With SusPhos, SNB has found a cooperation partner that makes this possible. With the joint development of a phosphate recycling plant of SNB and SusPhos in Moerdijk, we are taking an important step in our ambition to realise a circular wastewater chain.
