Diamond-enabled cleaning is moving into food and beverage plants through a May 20, 2026 partnership between Element Six (E6), the synthetic diamond advanced materials company owned by De Beers Group, and Oxi-Tech Solutions, a UK clean-tech firm. Their pitch is simple: generate disinfecting ozone on site from water and low-voltage electricity, then make the electrode tough enough for industrial cleaning.
The commercial test sits in daily plant life: heat cycles, biofilms, validation logs, rinse water, and managers who cannot risk a failed clean for a green headline.
The Deal Turns Synthetic Diamond Into a Cleaning Part
Element Six’s May 20 partnership announcement says the companies will scale Oxi-Tech’s Pulse Oxidation systems across agriculture, farming, food production and other sanitation-heavy sectors. The same announcement says the system uses water and low-voltage electricity to generate ozone, a short-lived disinfectant aimed at bacteria, viruses and microorganisms.
The material twist is boron-doped diamond (BDD, synthetic diamond made electrically conductive by adding boron atoms). Plain diamond is famous for hardness and chemical resistance. Add boron, and it can work as an electrode inside an electrochemical cell while keeping the durability that makes diamond useful in harsh settings.
That makes the deal the commercial scale test for a technology that sounds exotic but is being sold as a maintenance part. Oxi-Tech brings the sanitation hardware and field data. E6 brings the electrode manufacturing know-how and the balance sheet comfort that food processors usually want before changing cleaning routines.
The Dairy Pilot Gives the Deal Its First Numbers
At Yeo Valley’s Yoxter Organic Farm in Blagdon, Somerset, the system has already moved beyond a laboratory claim. Oxi-Tech’s Yoxter Farm validation note says the installation was used in a dairy clean-in-place process for a 100-cow British Friesian herd plus followers.
- 75% reduction in chemical use was reported at the site.
- 75% reduction in hot water use was also reported in the dairy cleaning process.
- 30% improvement was reported in Bactoscan, a dairy bacteria-count indicator.
- 75% fewer blue barrels were left for disposal after the switch.
Those figures matter because the dairy plant is a hard venue for sanitation shortcuts. Milk residues foul surfaces quickly, bacteria can punish weak routines, and cleaning failure can turn into product loss. A smaller chemical store also changes the workday for farm staff, since fewer drums mean less handling, less storage risk and fewer disposal steps.
Clean-In-Place Is the Cost Center Diamond Has to Beat
Clean-in-place (CIP, automated washing of tanks, pipes and processing lines without taking equipment apart) is a quiet utility bill inside food and drink production. An Oklahoma State University CIP guide describes the method as a way to bring cleaning solution into contact with internal surfaces through spray heads, flooding or circulation.
In practice, that means sanitation teams manage time, flow, temperature, concentration and rinsing at once. A system that cuts chemicals but extends downtime can lose the argument. A system that saves hot water but leaves residues behind never gets past quality assurance.
- Heat is expensive, especially when plants repeat wash cycles across tanks and lines.
- Chemicals create purchase, storage, handling and wastewater burdens.
- Rinsing consumes water and can stretch downtime between production runs.
- Audit records must prove that the new routine matches or beats the old one.
A recent critical assessment of CIP in dairies put the process at 10% to 30% of the sector’s water and carbon footprints. That range explains why processors are open to alternatives, even when sanitation teams remain cautious.
Synthetic Diamond Has a Water Treatment Trail
E6 is not entering water treatment from a cold start. In 2024, the company announced a separate diamond-enabled PFAS destruction partnership with Lummus Technology, a process technology company, focused on per- and polyfluoroalkyl substances (PFAS, persistent industrial chemicals that resist breakdown).
| Use Case | Partner Or Site | Evidence So Far | Scaling Question |
|---|---|---|---|
| Dairy sanitation | Yoxter Organic Farm | Chemicals and hot water both cut by 75% | Can the gains hold across larger circuits? |
| Beverage bottling | Sandford Orchards adoption note | Carbon footprint cut by more than 4 tonnes a year | Can cider results travel to other drinks? |
| PFAS water treatment | Lummus Technology | Free-standing BDD electrodes tested on long and short chain PFAS | Can capital cost fit municipal and industrial budgets? |
The shared thread is oxidation at the surface of a diamond-based electrode. The markets differ, but the buyer question repeats: does the electrode last long enough to make the cleaner process cheaper, safer or easier to permit?
Food Plants Want Lower Inputs Without Sanitation Risk
Ozone has an obvious appeal for food facilities because it can be generated at the point of use and then breaks down quickly. That same short life also means a plant cannot rely on a lingering chemical residual after the system shuts off. Dose, contact time and monitoring become the center of the sale.
A BDD ozone generation study in the Journal of Environmental Chemical Engineering described boron-doped diamond electrodes as promising for electrochemical ozone generation because of their oxygen evolution potential and anodic stability. The commercial issue is less glamorous: electrodes have to survive fouling, cleaning cycles and operator mistakes.
For processors, validation beats novelty. A sanitation manager needs swab results, bacteria counts, rinse records and a written method that auditors can follow. That is why the Yoxter data is useful to the partnership. It gives sales teams a working farm example with numbers tied to hygiene, not just sustainability.
Paul Morris, Oxi-Tech’s chief executive, has positioned the E6 deal as a way to scale faster. Siobhán Duffy, Element Six’s chief executive, has tied the partnership to simpler, safer and more sustainable cleaning across agriculture and food production. Those are broad claims. Factory trials will make them narrower and more useful.
Factory Scale Will Decide the Payoff
The next market is bigger than a farm dairy. High-throughput food plants and beverage lines run longer hours, face tighter changeover windows and often have more complex pipework. Municipal and industrial CIP systems add another layer of procurement, since a sustainability gain has to compete with maintenance budgets and uptime guarantees.
That is where the De Beers connection helps E6. Food manufacturers do not need jewelry romance; they need confidence that a specialized electrode will be available, consistent and supportable over years. Diamond’s role here is industrial, not decorative. It sits inside a cell and earns its place by reducing heat, chemicals and waste without adding new failure points.
The next bottleneck is plant-by-plant proof. Dairy data can open doors in cheese, yogurt and milk processing. Beverage data can help with bottling. But each product leaves different residues, each line has different valves and dead legs, and each quality team has its own risk threshold.
If the technology keeps those farm-level reductions on longer factory runs, plant managers get a cleaner utility bill without changing the hygiene standard. If validation slips at higher throughput, the partnership remains a promising pilot with a harder sales cycle.
