Susphos

What Susphos does

SusPhos B.V. is a Dutch private deep-tech company founded in 2019 that has developed a proprietary, multi-patented zero-waste process to recover phosphate from incinerated sewage sludge ash and convert it into four commercial products: Phoenix SSPlus (a low-carbon Single Super Phosphate replacement), Phoenix Emerald (a low-contaminant fertilizer feedstock), Phoenix Bond (a carbon-neutral cement replacement binder), and KORNaid (a granulation enhancer for fertilizer manufacturers). The underlying technology recovers over 80% of phosphate content while generating no waste byproducts and achieving up to 98% CO2 reduction versus virgin phosphate production, and has been validated at pilot scale at the Leeuwarden wastewater treatment plant.

The company's go-to-market is enterprise B2B with a co-location strategy: plants are designed to be sited adjacent to sewage sludge incinerators to secure feedstock and minimize logistics, with output sold directly to fertilizer manufacturers, cement producers, and construction companies. Revenue is not yet generated commercially; the company's first full-scale facility (SusPhos One, 40 kton/year ash processing capacity) is being constructed via a joint venture (S&S Feniks) with SNB — Europe's largest sewage sludge incinerator, processing ~30% of Dutch sewage sludge — at Moerdijk and is scheduled for 2028 operation. To date SusPhos has been funded primarily through non-dilutive EU and Dutch innovation grants (€1.1M JTF in 2024, €2.4M EIC in 2022, plus earlier regional support), and has not disclosed venture capital or institutional equity investment in available materials.

Customer segments targeted are wastewater treatment plants (host/feedstock partners), fertilizer manufacturers (Phoenix SSPlus, Phoenix Emerald, KORNaid buyers), and cement/construction firms (Phoenix Bond buyers). The company operates from a 20+ person team based at WaterCampus in Leeuwarden with engineering support from Bilfinger, and has secured multiple regulatory certifications (CMC 13, FPR, REACH, NEN7383, AP04) and a CES 2024 Innovation Award.

Core offering

Susphos develops and commercializes proprietary zero-waste technology that recovers phosphate from sewage sludge ash, converting waste streams into sustainable phosphate products for the fertilizer, cement, and wastewater treatment industries. The company produces and sells its own branded phosphate-based products (Phoenix SSPlus, Phoenix Bond, Phoenix Emerald, KORNaid) and operates production facilities alongside licensing its recovery process.

Product overview

Susphos operates as a phosphate recycling technology company offering a suite of four circular products derived from sewage sludge ash through its proprietary zero-waste technology. The portfolio consists of Phoenix SSPlus® (a low-carbon phosphate fertilizer replacing conventional SSP), Phoenix Bond® (a carbon-neutral cement replacement binder), Phoenix Emerald® (a raw material for fertiliser production), and KORNaid (a granulation enhancer for fertilizer manufacturing). These products transform previously discarded phosphate-rich waste into commercially viable, market-ready circular products.

Direct peers

• Ostara Nutrient Recovery Technologies: Recovers nutrients (notably phosphorus as Crystal Green struvite-based fertilizer) from wastewater streams for agricultural use. Directly comparable to SusPhos as a nutrient-recovery-from-wastewater company selling recovered phosphate fertilizer to agriculture.
• EasyMining (Sweden): Swedish company commercializing processes to recover phosphate and other minerals from waste streams including sewage sludge ash. Most direct European competitor in the recovered-phosphate-from-ash niche that SusPhos targets.
• NuReSys: Belgian nutrient recovery technology provider producing struvite and other recovered phosphorus products from wastewater treatment plants. Closely comparable business model recovering phosphorus products for fertilizer markets.

Emerging players

• Cambrian Innovation: US-based resource-recovery company converting wastewater and organic waste streams into valuable products including fertilizers. Comparable resource-recovery approach and B2B selling recovered nutrients to industrial buyers.
• PHORwater / P-REX (EU project): EU-backed phosphate-recovery consortium developing technologies to recover phosphorus from wastewater and sludge ashes. Comparable as a publicly funded effort targeting the same recovered-from-ash phosphate market SusPhos serves.

Broad incumbents

• Veolia Environnement: Global water and waste management incumbent operating wastewater treatment, sludge incineration, and nutrient-recovery pilots across Europe. Comparable as the dominant wastewater/sludge incineration operator that SusPhos' technology could partner with or supply.
• Suez (SUEZ / Saur): Major water and wastewater utility group in Europe with sludge incineration assets and growing interest in nutrient recovery. Comparable as a likely integrator/customer of phosphate-recovery technologies at large wastewater sites.
• ICL Group: Global specialty fertilizer and phosphate producer with connections to SusPhos advisory board (ICL Fertilizers veteran). Comparable as a downstream buyer of recovered phosphate products and a benchmark for end-market fertilizer pricing.
• Yara International: World's largest nitrogen fertilizer producer, expanding into specialty phosphate and low-carbon fertilizers. Comparable as a large enterprise buyer of sustainable phosphate inputs and a benchmark for low-cadmium fertilizer premiums.

Others

• SNB (N.V. Slibverwerking Noord-Brabant): Europe's largest mono-incineration sewage sludge plant and SusPhos' JV partner for S&S Feniks. Comparable as both feedstock supplier and the integrated operational partner for the first full-scale SusPhos plant at Moerdijk.
