Struvite and Vivianite Fertilizers Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Struvite and Vivianite Fertilizers Market Trends and Insights

Rising Phosphorus Recovery Mandates in Wastewater Infrastructure

Binding legislative timelines remain the clearest growth engine for the struvite and vivianite fertilizers market in 2026. The revised Urban Wastewater Treatment Directive took effect on January 1, 2025, and requires the European Commission to define a combined minimum rate for phosphorus reuse and recycling by January 2028^{[2]Source: European Sustainable Phosphorus Platform, “ESPP Proposals on Minimum Reuse and Recycling Rate for Phosphorus from Urban Wastewater,” European Sustainable Phosphorus Platform, phosphorusplatform.eu}. The directive now covers agglomerations of 1,000 or more inhabitants, bringing many smaller municipalities into compliance and expanding the project pipeline for the Struvite and vivianite fertilizer market. Germany has already set a firm national direction by requiring large wastewater treatment plants to recover phosphorus from 2029 onward, and this has begun to shift feasibility studies toward engineering and planning decisions. The European Critical Raw Materials Act adds another layer of support because phosphate is explicitly listed, thereby strengthening political accountability for national recovery plans. This policy structure reduces uncertainty for operators, lenders, and fertilizer buyers, and gives the Struvite and vivianite fertilizer market a clearer path from wastewater compliance to commercial nutrient recovery.

Circular Economy Procurement by Municipal Utilities and Food Processors

Procurement behavior is shifting from waste handling to resource recovery, and that change is helping the struvite and vivianite fertilizers market secure more dependable offtake structures. Municipal utilities in Belgium, the Netherlands, and Scandinavia are increasingly linking nutrient recovery to biosolids and wastewater contracts, which gives producers more stable supply volumes over multi-year periods. Food and beverage processors also support this shift by seeking lower-impact nutrient sourcing for contract growers, opening a second commercial channel beyond compliance-driven demand. Veolia Environnement S.A. positioned its struvia platform to benefit from this trend, and its Lille pilot demonstrated phosphorus recovery rates of up to 75%, supporting practical procurement use cases in 2025. When utilities and processors commit to recovered nutrient pathways, project bankability improves because the revenue side becomes easier to forecast. This helps shorten commercial timelines for new operators and strengthens the transition of the Struvite and vivianite fertilizers market from pilot activity to repeatable supply contracts.

Premium Slow-Release Fertilizer Adoption in High-Value Crops

Premium crop systems are providing the struvite and vivianite fertilizer market with an attractive pool of demand because nutrient efficiency matters more in high-value harvests. Struvite releases phosphorus in a crop-demand-driven pattern, making it useful for growers seeking better nutrient timing and lower leaching losses. In June 2026, Ostara Nutrient Recovery Technologies Inc. introduced a higher-analysis CG P2X formulation that delivers more than 2 times the plant-available nitrogen, phosphorus, and magnesium of conventional phosphate fertilizers, and the company stated that application rates can be 40% lower than monoammonium phosphate, diammonium phosphate, and triple superphosphate^{[3]Source: Ostara, “Ostara Advances CG P2X with New, Higher-Analysis Formula Delivering More Than 2X the Plant-Available Nutrients,” June 8, 2026, Ostara.com}. In April 2024, Crystal Green Pearl became the first pure struvite crop nutrition source to receive organic registration across Germany, Spain, Denmark, Austria, and the Netherlands, which opened a premium sales channel tied to certified organic production. That combination of agronomic value and certification support gives specialty growers a clearer reason to pay for recovered phosphorus products. As more growers prioritize traceable inputs and controlled nutrient release, premium crop adoption should remain an important growth layer for the Struvite and vivianite fertilizers market.

Struvite Commercial Acceptance Through CE Mark and Organic Certification

Commercial acceptance matters because it reduces adoption friction across the struvite and vivianite fertilizers market. In Europe, struvite benefits from recognition under the CMC12 framework, which gives producers a clearer route to market than many other recovered phosphorus products. NuReSys NV, part of Green Tile BV, has continued to operate controlled struvite crystallization systems with an active CMC12 pathway for its Biostru product, which supports continued blending and off-take expansion. Organic registration has added another layer of confidence because certified channels require stronger documentation and product consistency. When recovered fertilizer meets both compliance and premium-channel requirements, distributors and growers face fewer doubts about its use, labeling, and provenance. This lowers commercialization barriers for the Struvite and vivianite fertilizers market and supports a shift from trial-based demand to repeat purchases across established agricultural systems.

Limited Farmer Awareness of Recovered Mineral Fertilizers

Farmer awareness remains a real constraint because the Struvite and vivianite fertilizer market still relies on products that differ from familiar phosphate inputs in both origin and performance. Growers often need evidence on nutrient release, crop response, handling, and certification before they shift from established fertilizer programs to recovered mineral products. The fact that organic registration and product reformulation are emphasized so strongly in company communications shows that buyer education remains central to commercial conversion. This issue is more visible in price-sensitive farming systems, where growers may hesitate to pay a premium unless yield response or policy support is clearly demonstrated. It also slows distributor adoption because channel partners need a simpler sales story before they can promote new products at scale. As a result, commercial growth in the struvite and vivianite fertilizer market can lag behind technical readiness while awareness, training, and field-level confidence are still developing.

Uneven Product Standardization Across Jurisdictions

Regulatory fragmentation continues to raise costs and delay cross-border expansion in the Struvite and vivianite fertilizers market. The United States follows a different regulatory path linked to biosolids and state fertilizer registration, while Japan uses its own agricultural and recycling framework rather than the European Union classification route. No harmonized international standard exists yet for recovered mineral phosphorus fertilizers, leaving producers with multiple approval tracks rather than a single scalable process. The European Commission will not specify the delegated minimum phosphorus recycling rate until early 2028, so some interpretive uncertainty will remain in the near term. This can extend commercial launch timelines by many months and makes multi-region sales more difficult than the underlying agronomic case would suggest.

Segment Analysis

By Product Type: Struvite Anchors Revenue as Vivianite Scales

Struvite represented 97.5% of the struvite and vivianite fertilizers market size in 2025, which reflects its longer commercial history, broader field validation, and clearer regulatory status in Europe. Vivianite remained the smaller product category because it is still earlier in commercial development and lacks the same level of product recognition across fertilizer systems. Struvite also benefits from a stronger record in crop nutrition and blending compatibility, which keeps it ahead in present revenue contribution across the Struvite and vivianite fertilizers market.

Vivianite is anticipated to grow at an 11.2% CAGR through 2031, making it the fastest-growing product type in the market. Pilot magnetic separation has already shown recovery above 80% from digested sludge, and industrial wastewater trials reported phosphorus recovery of 93.54% under optimized conditions^{[4]Source: W.K. Wijdeveld, G. Sudintas, Philipp Kuntke, Leon Korving, and Mark C.M. van Loosdrecht, “Robust Magnetic Vivianite Recovery from Digested Sewage Sludge,” Water Research, doi.org}. Struvite should continue to expand as well because its agronomic value, organic certification base, and commercial positioning remain stronger today. The result is a market where struvite supports near-term revenue while vivianite strengthens future growth potential.

By Form: Solid Products Lead as Liquid and Fine-Particle Formats Gain Ground

Solid products accounted for 95.2% of revenue in 2025, maintaining their dominant position in the global struvite and vivianite fertilizers market due to their compatibility with conventional fertilizer blending, storage, transportation, and field application systems. Most commercially available struvite fertilizers are offered as granules or pellets, supporting their widespread adoption across row crops, horticulture, turf, and specialty agriculture. Liquid products accounted for a much smaller share, with adoption primarily limited to specialized nutrient management programs and research-driven applications in which recovered phosphorus is incorporated into liquid formulations.

The liquid segment is estimated to advance at a 10.4% CAGR through 2031, driven by increasing adoption of fertigation and precision irrigation systems, along with ongoing research to improve the integration of recovered phosphorus into liquid nutrient solutions. However, solid fertilizers are expected to retain their market leadership throughout the forecast period, as most commercial struvite and emerging vivianite products are manufactured and marketed in granular or pelletized forms, offering superior handling, storage stability, and slow-release nutrient performance.

By Source: Wastewater Treatment Plants Lead, Anaerobic Digestion Routes Enable Vivianite

Wastewater treatment plants held 54.1% of the struvite and vivianite fertilizers market share in 2025, making them the dominant source because centrate and sidestream flows offer more consistent recovery conditions. Anaerobic digestion and biosolids streams emerged as increasingly important sources, while manure and agricultural residues remained a smaller but viable feedstock pool. Full-scale wastewater systems can achieve phosphorus recovery rates of 80% to 95%, and operators also benefit from lower scaling pressure in digesters and related equipment.

Anaerobic digestion and biosolids streams are projected to grow at a 10.1% CAGR through 2031, the fastest pace among source categories in the struvite and vivianite fertilizers market. Their importance comes from the reducing conditions that support vivianite formation, which gives this source a stronger link to the emerging vivianite supply base. Manure and agricultural residues should also continue to be developed, although compositional variability still complicates scaling compared with municipal wastewater systems. This leaves wastewater plants as the most stable source today, while digestion-linked streams shape a larger share of the future growth path.

By Application: Field Crops Anchor Volume as Horticultural Segment Builds Premium Value

Field crops captured 38.5% of demand in 2025, which kept them as the largest application area in the Struvite and vivianite fertilizers market because they absorb the greatest nutrient volumes. Horticultural crops followed as a smaller but increasingly valuable channel, while turf and ornamental applications remained a stable niche with clearer runoff and liability benefits. In field crop systems, slow-release phosphorus suits long growing cycles and helps reduce fixation losses in soils where conventional soluble phosphate performs less efficiently. 

Horticultural crops are estimated to grow at a CAGR of 8.1% between 2026 and 2031, supported by premium economics and a stronger willingness to pay for certified recovered inputs. Organic registration across 5 European countries improves access to produce growers who need documented nutrient provenance before changing input programs. Turf and ornamental demand should remain steady because low heavy-metal concerns and reduced runoff risk align with municipal and managed-landscape requirements. The application mix is therefore separating into volume-led field use and value-led horticultural adoption over the forecast period.

Geography Analysis

Europe held 38.2% of the global struvite and vivianite fertilizers market in 2025, making it the leading regional market, supported by more advanced wastewater infrastructure, phosphorus-recovery capabilities, and regulatory frameworks. The Netherlands, Germany, Denmark, and France have emerged as key production hubs, with established experience in struvite recovery. For example, REMONDIS SE & Co. KG operates a commercial phosphorus-recovery facility in Hamburg and is developing additional TetraPhos projects in Germany and the Netherlands. With regulatory requirements, established certification pathways, and strong links between recovery facilities and municipal utilities, Europe is expected to maintain its leading position in the market.

Asia-Pacific is anticipated to grow at a 9.8% CAGR through 2031, which makes it the fastest-growing region in the struvite and vivianite fertilizers market. China offers the largest near-term volume base because municipal treatment coverage and livestock-related nutrient streams are both extensive. Japan and South Korea remain important for vivianite development because their phosphorus recycling frameworks helped move pilot work closer to commercial practice. India is also becoming more relevant to the struvite fertilizer market as wastewater treatment and nutrient-recovery initiatives gain importance, creating a longer-term basis for domestic phosphorus recovery. The country’s large agricultural sector and growing need for efficient phosphorus management provide potential demand for recovered-phosphorus fertilizers such as struvite, particularly as circular-economy approaches to wastewater and nutrient management develop.

North America remains the one of the largest regional positions in the struvite and vivianite fertilizers market, with the United States as the main demand center. South America, led by Brazil and Argentina, has strong agricultural demand potential but more limited wastewater infrastructure outside major urban areas. The Middle East and Africa remain early-stage markets for struvite and vivianite fertilizers, with growing investment in wastewater treatment and water reuse creating a foundation for phosphorus recovery. However, limited commercial-scale recovery capacity and developing regulatory and certification frameworks continue to constrain market development. Near-term opportunities will therefore depend on wastewater infrastructure expansion, successful recovery projects, product approval pathways, and the economics of producing recovered-phosphorus fertilizers.
