SusPhos is a Dutch spin off company of the University of Amsterdam - where the SusPhos process was developed. By the end of this year, we will have scaled up our process and built our pilot plant.
SusPhos stands for optimally upgrading waste into market-known products. With our extensive chemical knowledge, we realise a complete upcycling of phosphate waste streams to create a waste-free process. We focus on reusing all elements to avoid discarding anything.
The patented SusPhos process is a robust process that can produce a variety of market known, high-quality phosphate products. These range across several markets, including the flame-retardant and fertilizer industries.
Upcycling struvite into high quality products: AquaMinerals & SusPhos team up for phosphate recycling
At the moment, the Netherlands does not have a phosphorus shortage in the soils, but a surplus due to the overuse of phosphorus fertilizers and manure. On top of that, the composition of struvite is not always ideal for direct application in agriculture. With the unique SusPhos process, we can convert the struvite into flame-retardants, a different market with a growing potential due to the ban of halogenated, toxic flame-retardants. SusPhos offers a renewable recycled, economically attractive and high-quality product for a real market need.
AquaMinerals and SusPhos are happy to announce the collaboration on the necessary research on struvite and the possibility to use the struvite produced at the water authorities as a sustainable raw material for the SusPhos plant. Both parties acknowledge the importance of the recovery of other elements in struvite such as magnesium and nitrogen and will include this in their collaboration.
SusPhos will build its Pilot at Paques Technology BV and run the pilot at the wastewater treatment plant of Leeuwarden, Wetterskip Fryslân. The cooperation between SusPhos and AquaMinerals has been supported as well by the Energy and Resources Factory (EFGF), the network organization of the all regional water authorities that stimulates recovery of raw materials and energy from waste water.
01 / MULTIPLE FEED STOCKS
Our unique, patented process is compatible with several industrial waste streams, including agriculture, communal waste, and the food & beverage industry.
02 / HIGH QUALITY PRODUCTS
Our first products will be high quality flame retardants and specialty fertilizers. Besides these, we can produce a wide range of other high quality, phosphate rich products. SusPhos will be the first to provide customers with high quality sustainable phosphate products
03 / NO WASTE
We only produce products, we do not believe in waste. We will always try to find the best solution to incorporate all the elements from the starting material into valuable products.

dr. Steven van Zutphen
Chemist and business developer, Steven started and succesfully exited a start-up manufacturing polymers for precious metal capture from waste and process water. After integrating this technology in a wider mining and refining chemistry portfolio with the buyer, he joined Susphos to help structuring the company and start the growth of the business.
dr. Chris Slootweg
Chris is one of the founders of SusPhos and scientific advisor of SusPhos. He holds a position of associate professor at the University of Amsterdam. The mission of his laboratory is to work at the intersection of fundamental physical organic chemistry, main group chemistry and circular chemistry. Chris is highly motivated to promote the 12 principles of circular chemistry (published in Nature Chemistry) with appealing case studies to enable the circular economy – SusPhos is one of them.
ing. Bas de Jong
Bas is one of the founders of SusPhos and R&D advisor of SusPhos. He is a senior technician and highly experienced in phosphorus chemistry and accompanying technologies, building lab scale prototypes and is a star in finding solutions for challenging chemical problems.
Steven Beijer MSc
Steven is researcher and focuses on the SusPhos process. During his Masters in Sustainable Chemistry, Dr. Chris Slootweg sparked his interest for the sustainable use of Phosphorus. He graduated working on the SusPhos process, making a large contribution to the company’s technology. After finishing his studies, he returned at the beginning of this year to continue his research as an integral part of the SusPhos team.
