Fries from Recovered Phosphate – Thanks to Puraloop^® and the KNAP Project

What if you could turn your residual streams into a source of growth?

With Puraloop, we make this possible. This innovative fertilizer is the tangible result of the unique collaboration project Closing the cycle of nutrients from wastewater and process water (KNAP), in which ICL works in partnership with organizations such as Wageningen University and Research, Lamb Weston, and the Nutrient Platform. Together, we close the nutrient cycle and give recycled phosphate a new future in agriculture.

On a sunny day in May, visitors to the international IWA Resource Recovery Conference in Leeuwarden literally got a taste of circular agriculture. Together with our KNAP partners, we shared freshly made fries, produced from potatoes grown using Puraloop.

A delicious conclusion to a successful day, full of discussions about the power of reuse and collaboration.

What is Puraloop?

Puraloop is a circular phosphate fertilizer made from recovered phosphate from residual streams. The fertilizer is granular, safe, and dust-free, and it fits seamlessly into modern agricultural systems. Thanks to a smart combination of directly available and root-activated phosphate, Puraloop is both efficient and effective.

It’s more than just a fertilizer – it’s a pioneer of circular agriculture.

Why choose Puraloop?

• Circular and sustainable –

  • Made from residual streams such as sewage sludge ash, without compromising on quality or effectiveness.

• Complete plant nutrition –

  • Contains phosphate, calcium, magnesium, sulfur, and zinc – for strong roots and healthy crop development.

• Safe and certified –

  • Approved for use in European agriculture and meets all quality and safety standards.

Working Together for a Circular Future

The success of Puraloop is the result of true collaboration. Within the KNAP project, companies, governments, and knowledge institutions share a joint mission: to close the phosphate cycle. ICL contributes not only technology, but also vision and determination. This project demonstrates that innovation truly works – when it is done together.
