The 2026 Nutrient Recovery Market at a Glance
The nutrient recovery systems market is forecast to reach US$ 12.20 billion by 2032, up from roughly US$ 5.1 billion in 2024, with phosphorus recovery, ammonia stripping, and bio-based upcycling as the fastest-growing technology segments (per the Nutrient Recovery Systems market report, 2024-2032 outlook). The leading nutrient recovery key players in 2026 cluster into four groups: struvite and crystallization specialists (Ostara, NuReSys, GSR Solutions), full-stack water majors (Veolia, Suez, Xylem, Alfa Laval, Royal HaskoningDHV), biological upcyclers (Cambi, AgriProtein, Anuvia, Nutrient Recovery & Upcycling LLC), and equipment OEMs and integrators (DVO, CNP - Centrisys, Trident Process, Lenntech, Clearas Water Recovery).
Four regulatory and market forces are driving that growth in 2026: tighter EU nitrogen and phosphorus discharge ceilings under the revised Urban Waste Water Directive, US state-level nutrient criteria in Florida, Ohio, and the Chesapeake Bay watershed, Asia-Pacific fertilizer self-sufficiency programs (notably China's 14th Five-Year Plan water chapter), and ESG-linked industrial water disclosure under CDP Water Security and IFRS S2. The 17 vendors profiled below span three technology families: chemical and crystallization (struvite, calcium phosphate), biological and organomineral upcycling (insect protein, algae, organomineral fertilizer), and physical and membrane separation (ammonia stripping, ion exchange, RO concentration).

How We Categorized the 2026 Nutrient Recovery Key Players
Vendor selection followed a single rule: the firm had to appear in either the 2024-2025 Nutrient Recovery Systems or Nutrient Recycling market report and have a commercial 2026 product line, which gave 17 companies that fit cleanly into four categories. Struvite and crystallization specialists (Ostara, NuReSys, GSR Solutions) license reactor IP and sell the recovered fertilizer; full-stack water majors (Veolia, Suez, Xylem, Alfa Laval, Royal HaskoningDHV) deliver EPCs and operate plants globally, often bundling their own or licensed recovery units; biological and organomineral upcyclers (Cambi, AgriProtein, Anuvia, Nutrient Recovery & Upcycling LLC, BioHiTech) valorize the nutrient-laden organic fraction into feed or soil products rather than recovering a pure salt; and equipment OEMs and integrators (DVO, CNP - Centrisys, Trident Process, Lenntech, Clearas Water Recovery) supply the dewatering, centrifuge, membrane, or algal-contact hardware that the recovery trains rely on.
Some firms straddle two layers and the table flags that explicitly. Suez runs both thermal hydrolysis (Aquadvantage) and Ostara-licensed struvite polishing; Veolia operates AnoxKaldnes MBBR pretreatment, Hydrex chemical dosing, and air-stripping trains; Alfa Laval sells decanter centrifuges and AlfaVap heat-based ammonia stripping as a unit; and Cambi's THP output feeds downstream biological upcyclers rather than producing a pure nutrient salt. The other 2026 caveat is geographic: Western-published 2026 lists under-represent Asia-Pacific and Chinese recovery vendors such as Beijing Originwater and university spinouts out of Tongji and Zhejiang, and procurement teams running 2026 industrial bids in the region should ask vendors about local Chinese EPC partners that do not show up in English-language market reports.
Vendor Leaderboard: 2026 Nutrient Recovery Key Players Compared
Comparing 17 vendors on six fields (headquarters, primary technology, target nutrient, typical capacity, indicative application) is the part most 2026 list-style pages skip. The table below is meant to be screenshot-friendly: pick two or three rows that match your influent profile and flow rate, then move to the technology-vs-vendor matrix in the next section.
| Vendor | HQ / Region | Primary Technology | Target Nutrient | Typical Capacity | Indicative Application |
|---|---|---|---|---|---|
| Ostara Nutrient Recovery Technologies | Canada / North America | Pearl® struvite crystallization | P (incidental N) | 1-20 ton P/day per reactor | Municipal + industrial, multiple US/Canada sites operational 2026 |
| NuReSys NV | Belgium / EU | NuReSys-STRUVIA struvite reactor | N + P from centrate | 50-500 kg struvite/day | European municipal AD centrate |
| GSR Solutions | Netherlands / EU | Phosphogreen™ calcium phosphate | P, high-P streams | Vendor reports ~95% P recovery | Industrial high-P waste streams (food, fertilizer) |
| Clearas Water Recovery | US | Algal-biological nutrient uptake | N + P (biomass) | 0.1-5 MGD | Small-to-mid municipal WWTPs |
| DVO Inc. | US | ANT-X2 dewatering / centrifuge | Solids for downstream P | Up to ~200 m³/h | Struvite dewatering step, biogas |
| CNP - Centrisys | US / Germany | Centrifuge + CSBR for nutrient biosolids | Solids-bound N + P | 10-100 m³/h per unit | Equipment OEM for biosolids trains |
| Xylem | US, global | Leopold filter, Wedeco UV, Sanitaire aeration | Nutrient polishing | Plant-scale | Integrates polishing rather than primary recovery |
| Alfa Laval | Sweden, global | Decanter centrifuges + AlfaVap stripping | N as ammonium sulfate | 1-50 ton N/day | Biogas and fertilizer plants |
| Royal HaskoningDHV | Netherlands, global | Nereda® SBR + struvite polishing design | N + P (design role) | Plant-scale | Engineering consultancy + integration |
| Lenntech | Netherlands, global | Membrane stripping + ion-exchange trains | N + P | 10-500 m³/d packaged | System integrator, mid-scale industrial |
| Veolia | France, global | AnoxKaldnes MBBR, Hydrex dosing, stripping | N + P (full-scope) | Plant-scale EPCs | Tampa Bay, Chinese industrial parks, 2026 contracts |
| Suez | France, global | Aquadvantage THP + Ostara-licensed struvite | N + P (full-scope) | Plant-scale EPCs | Municipal + industrial, 2026 multi-site rollouts |
| Cambi AS | Norway, global | Thermal hydrolysis (THP) biosolids | Indirect N + P (concentrate) | 10-100 ton DS/day | Feeds downstream upcyclers |
| AgriProtein Holdings | South Africa / UK | Insect (black soldier fly) bioconversion | Organic N into MagMeal | 10-100 ton feed/day per plant | Food waste, manure, offal streams |
| Anuvia Plant Nutrients | US | SymTRX organomineral fertilizer | N + P into soil product | 50-200 kton/yr | Industrial co-product streams |
| Nutrient Recovery & Upcycling LLC | US | Emerging biological upcycling | N + P (biomass) | Regional mid-scale | Food + ag processing sites |
| BioHiTech Global Inc. | US | Anaerobic digestion + nutrient recovery | N + P (digestate) | 5-50 ton waste/day | Food waste, smaller industrial sites |
Indicative CAPEX and OPEX for these technologies fall into recognizable bands per kg of nutrient recovered: struvite crystallization typically lands at roughly US$ 3-8/kg P OPEX with mid-six-figure to low-seven-figure CAPEX per train at municipal scale; ammonia stripping and membrane concentration run US$ 2-6/kg N OPEX with CAPEX dominated by heat exchangers or membrane cassettes; biological upcycling has lower CAPEX but a high OPEX component tied to insect or algae feed logistics. The 2026 vendor-specific numbers vary by capacity, so the right move is to ask each shortlisted vendor for audited OPEX in $/kg nutrient at your flow rate, not rely on industry-average charts. The upstream and downstream links in a recovery train — the DAF system for upstream P and TSS removal ahead of struvite crystallization and a plate and frame filter press for dewatering struvite and recovered biosolids — sit with equipment OEMs rather than the recovery IP holders listed above.
Technology vs. Vendor: Which Key Player Fits Your Waste Stream
The leaderboard tells you who the players are; this table tells you which of them to actually call. Influent profile, not vendor reputation, is the strongest filter at the shortlisting stage.
| Technology | Typical Recovery Efficiency (vendor-reported) | Representative 2026 Vendors |
|---|---|---|
| Struvite crystallization (fluidized bed) | 80-95% P, 10-30% incidental N | Ostara, NuReSys, GSR Solutions, Suez (Ostara license) |
| Ammonia stripping (air / steam) | 70-95% N as ammonium sulfate | Alfa Laval, Veolia, Suez, Lenntech |
| Membrane / RO concentration | 90-99% N retention, concentrate to crystallizer | Veolia, Suez, Lenntech |
| Biological upcycling (insects / algae) | Variable N+P uptake, valorizes organics | AgriProtein, Anuvia, Cambi (indirect), Nutrient Recovery & Upcycling |
| Ion exchange / struvite polishing | Polish step for low-P residuals | GSR Solutions, Ostara, Lenntech |
Rule of thumb for routing: if influent PO4-P is above 50 mg/L, prioritize struvite or calcium phosphate crystallization vendors (Ostara, NuReSys, GSR Solutions, Suez); if NH3-N is above 500 mg/L, prioritize stripping or membrane concentration vendors (Alfa Laval, Veolia, Suez, Lenntech); if organics valorization is the primary goal rather than a clean salt, the biological upcyclers (AgriProtein, Anuvia, Nutrient Recovery & Upcycling) are the right shortlist. Efficiency ranges in the table are vendor-published case-study figures, so flag them for verification during an RFQ pilot. A typical municipal AD centrate at 100-300 mg/L PO4-P and 800-1,500 mg/L NH3-N will often pair a membrane concentration step with a struvite reactor, which is why full-stack majors like Veolia and Suez keep winning the larger 2026 EPC awards. A lamella clarifier for nutrient-rich clarification before crystallization is the unit operation most often used to drop suspended solids ahead of either route.
How to Shortlist Nutrient Recovery Vendors in 2026
Four steps turn a 17-row table into a 2-3 vendor shortlist a procurement team can actually evaluate. Step 1 — define the waste stream. Characterize influent (N- or P-dominant), flow in m³/day, and target recovery form (struvite, ammonium sulfate, organic fertilizer). Vendors misaligned at this step will fail at the pilot stage, not at the contract stage. Step 2 — check technology-region fit. Struvite specialists (Ostara, NuReSys, GSR Solutions) dominate North America and Benelux municipal bids; Asian industrial buyers in 2026 will often get faster local support from system integrators (Lenntech, Alfa Laval) plus Chinese EPCs, even when the recovery IP itself is European. Step 3 — match scale to vendor business model. Ostara and NuReSys license unit processes; Suez and Veolia deliver full-scope EPCs; DVO and CNP supply equipment to integrators — pick the layer your project actually needs, because a struvite IP licensor is not going to deliver a 50,000 m³/d EPC and a major EPC is not going to sell you a single 200 kg/day reactor. Step 4 — validate commercial readiness in the RFQ. Ask for at least two 2024-2026 reference sites of comparable capacity, audited OPEX in $/kg nutrient recovered, and a real end-product offtake agreement. A chemical dosing system for struvite reactor Mg and pH control is one of the few long-lead items the buyer can specify in advance, which gives the RFQ more leverage.
2026 Outlook: Regulation, ESG, and Where the Vendor Map Is Moving
Three forces will reshape the vendor map through 2026 and 2027. First, regulation: the EU Urban Waste Water Directive revisions, US state nutrient criteria for Chesapeake Bay and Long Island Sound, and China's 14th Five-Year Plan water targets are all pushing recovery rates higher, which expands the addressable project list for every vendor in the leaderboard. Second, ESG and disclosure: CDP Water Security and IFRS S2 reporting in 2026 turn nutrient recovery into a line-item KPI for food, fertilizer, and microelectronics sites, which raises the executive-level value of a recovery train beyond simple compliance. Third, vendor structure: more Ostara-style IP licensing to full-stack EPC majors is likely, and insect or algae upcyclers are integrating with anaerobic digester EPCs to secure feedstock — a structural trend, not a specific M&A prediction. For equipment OEMs, the practical 2026 effect is rising demand for upstream screening, DAF, lamella clarification, and sludge dewatering that sit on either end of a recovery train.

How large is the nutrient recovery market in 2026?
The Nutrient Recovery Systems market is forecast to reach US$ 12.20 billion by 2032 from roughly US$ 5.1 billion in 2024, with phosphorus recovery, ammonia stripping, and bio-based upcycling as the fastest-growing segments.
Which technology recovers the most phosphorus from wastewater?
Fluidized-bed struvite and calcium phosphate crystallization report 80-95% P recovery in vendor case studies (Ostara Pearl, NuReSys-STRUVIA, GSR Phosphogreen), with membrane concentration often used upstream to lift the PO4-P feed.
What is the difference between struvite recovery and ammonia stripping?
Struvite reactors (Ostara, NuReSys) target phosphorus and precipitate it as magnesium ammonium phosphate; ammonia stripping (Alfa Laval AlfaVap, Veolia, Suez) targets high-N streams and produces ammonium sulfate for fertilizer.
Which vendors handle full-scope nutrient recovery EPCs?
Veolia and Suez are the two largest full-scope 2026 EPC contractors, bundling membrane, biological, and struvite polishing units under one contract, while Ostara, NuReSys, and GSR Solutions license the underlying recovery IP.
