Overview
Arbok-PhosVita converts phosphate waste and biological waste into organomineral fertilizer. Phosphate tailings have accumulated to 1 billion tonnes in Florida alone, with 100 million tonnes generated globally each year; their dust carries radiation and drives respiratory disease and oncology, while runoff feeds sargassum blooms that damage marine ecosystems. The United States spends $300 million annually on the medical consequences alone.
Thermo-vacuum stabilization extracts water from the liquid waste and concentrates the acids, which are then blended with organic matter — manure, sewage sludge, straw. The reaction neutralizes the acids, forming phosphates and carbonates, and the product is granulated fertilizer matching chemical analogues in quality at $50–200 per tonne against a market of $300–600.
Applications
Agricultural fertilization: nutrient-rich organomineral fertilizer for crops, improving soil fertility and water retention across diverse climates and soil types. Field-tested on soybean, wheat and corn in Florida, Iowa and Nebraska.
Waste management: transforms hazardous phosphate waste and bio-waste — manure, sewage sludge, plant residues — into a marketable product, removing disposal cost.
Strategic: eliminates the 5–15 % fertilizer shortage and replaces US imports running at $12 billion per year.
Operating Principle
The feedstock is an acid blend recovered from phosphate-industry waste streams, processed in vertical thermo-vacuum stabilization tanks with separate collection vessels for fertilizer, water and carbonates. Thermo-vacuum stabilization pulls the bulk of the water out of the liquid waste at ambient temperature under vacuum, concentrating the acid fraction into a stabilized intermediate referred to internally as PhosVita-Mix. Solid waste such as phosphogypsum is first ground and mixed with water of any quality — fresh, seawater or wastewater — before processing.
PhosVita-Mix is then blended with organic matter — manure, sewage sludge, or plant residues such as corn straw, grass, and sargassum — and the reaction neutralizes the acids to form phosphates and carbonates. Output is granulated fertilizer.
Each organic feedstock contributes nitrogen to the finished product at a different level, and the blend design is tuned to steer the output toward either a standard or a high-nitrogen fertilizer grade (see Section 5).
Feedstock mechanisms: PhosVita-Mix releases the large majority of the nutrients bound in manure, forming phosphates that materially raise soil moisture retention. Sewage sludge is converted into phosphorus compounds with the acids neutralized, restoring depleted soils.
Two fertilizer grades are produced, standard and high-nitrogen; nutrient concentrations for each are reported in Section 5 as a range, reflecting figures documented across ARBOK's internal sources.

Architecture and Components
Vertical thermo-vacuum stabilization tanks; grinding stage for solid feed such as phosphogypsum; acid concentration into the PhosVita-Mix intermediate; blending stage with organic matter; granulation; separate collection vessels for fertilizer, water and carbonates.
Advantages
Product: matches chemical fertilizers in quality at two to four times lower cost; two grades available, standard and high-nitrogen; certified for organic farming; raises yields 20–25 % and soil organic matter 15 %; increases soil moisture retention 30 %.
Process: 2 kWh per tonne; zero emissions; 70 % of water recycled; accepts water of any quality including seawater and wastewater for solid feed preparation.
Waste side: eliminates disposal of hazardous phosphate waste, and removes the health and environmental burden — radioactive dust driving respiratory disease and oncology, runoff feeding sargassum blooms.
Strategic: closes the 5–15 % fertilizer shortage; replaces $12 billion per year of US imports; positions the producer nation as a leader in the global fertilizer market.
Integrations
ARBOK-Phosphate · ARBOK-PHOSPHOGYPSUM · Arbok-Termite · ARBOK-FERTILIZER · ARBOK-SARGASSUM
Feedstock chain: phosphate plants and phosphogypsum stockpiles supply the mineral side; manure, sewage sludge and plant residues including sargassum supply the organic side. Arbok is separately developing biofuel from phosphate waste.
Deployment & Operation
Deployment scale planned: processing 10 million tonnes of phosphate waste and 20 million tonnes of bio-waste annually by 2030, scaling to 20 million and 40 million tonnes by 2050.
Industrial trials confirm no emissions and minimal operating costs, with readiness stated for large-scale deployment in agricultural sectors worldwide.
TRL
TRL 8 — set by Michael, 2026-08-06.
Industrial trials completed with confirmed absence of emissions and minimal operating cost; certified for organic farming; stated ready for large-scale deployment.
Market Potential
Waste base: 1 billion tonnes accumulated in Florida; 100 million tonnes generated globally per year. US manure at 1.2 billion tonnes/year, sewage sludge at 500 million tonnes/year, plant residues at 800 million tonnes/year.
Projected total revenue $56 billion over 25 years (2025–2050): $31–35 billion from fertilizers, $3–4 billion from biogas, plus $15–20 billion saved on waste management.
Additional revenue streams: methane at $1–2 million per year per facility; land reclamation valued at $1.5–2 billion over 25 years.
Cost avoided: the US currently spends $300 million per year on the medical consequences of phosphate tailings alone, and imports $12 billion per year of fertilizer.

| Energy | 2 kWh/tonne |
| Production cost | $60–100/tonne, including waste disposal compensation |
| Selling price | $50–200/tonne |
| Market price of equivalent fertilizer | $300–600/tonne |
| Price advantage | 2–4× cheaper; up to 50 % below market rates |
| Methane revenue | $1–2 million/year per facility |
| Land reclamation value | $1.5–2 billion over 25 years |
Risk Factors
Product formulation — nutrient grade and blend ratio — is tuned per feedstock and site conditions, which can introduce variability across installations until a larger base of standardized certification data accumulates. The 25-year $56 billion revenue projection rests on deployment volumes (10–20 million tonnes of phosphate waste annually) that are targets rather than contracted capacity.
The intermediate PhosVita-Mix is a concentrated acid solution, requiring corresponding handling procedures and corrosion-resistant materials. Feedstock includes sewage sludge, which carries its own regulatory regime for agricultural application in most jurisdictions.
