PHANTOM Pays for Itself — Two Ways
Disposal savings cut costs. Output revenue — compost sold to agriculture, solid fuel from plastics — generates income. Together they can cover a typical finance arrangement, making PHANTOM effectively self-funding.
Clinical, PPE & infectious waste via incineration · £617/tonne · NHS clinical waste incineration rate, 2026
Disposal rate: £617/t (NHS clinical waste incineration rate, 2026). Op cost: ~£33/cycle (kerosene boiler, 3t batch per Phantom 3M3 spec). Output yield: ~1.8t per 3t input (60%). Output revenue: indicative UK market rates. Machine price: ~¥260M FOB (~£1.37M / ~$1.75M). Lease model: 5-yr, 6% APR indicative only. ~1.27 USD/GBP. Actual results depend on waste composition, output quality, local market pricing, and financing terms.

Who Uses PHANTOM?
Six industry segments — each with a dedicated deep-dive guide covering regulations, disposal rates, and site-specific ROI.
NHS clinical waste incineration, 2026
Hospital / Clinical
Infectious clinical waste, PPE, used sharps packaging, and contaminated theatre materials. PHANTOM exceeds CDC autoclave sterilisation standards without combustion — no dioxins, no fly ash.
Get Assessment →Blended tiger-stripe + orange bag rate
Care Home / Nursing Home
Adult incontinence waste classified as clinical waste attracts the same high incineration rates as hospital waste in most jurisdictions. PHANTOM processes it at ~£33/cycle (~$42 USD).
Get Assessment →Organic recycling / exemption route
Farm / Livestock Operation
Manure, slurry, poultry litter, and fish by-products are converted into amino acid-rich liquid fertiliser and compost — creating a revenue stream from waste rather than a disposal cost.
Get Assessment →AD gate fee to contaminated landfill
Food Processing / Catering
Food waste from industrial kitchens, catering operations, and manufacturing lines. PHANTOM handles mixed and contaminated food streams that AD facilities reject — in 30 minutes, on-site.
Get Assessment →Landfill tax £130.75 + gate fee (2026)
Manufacturing / Industrial
Oil sludge, plastics, rubber, paint residue, and mixed industrial organics. PHANTOM converts waste that would otherwise attract maximum landfill tax into solid fuel or compost.
Get Assessment →Standard non-inert landfill rate, 2026
Municipal / Mixed Waste
For municipalities targeting zero-residual-waste goals. On-site PHANTOM installations provide an immediate path to near-zero residual waste without incineration infrastructure.

The Process
Three Steps. Thirty Minutes.
Subcritical water hydrolysis requires no additives, no combustion, and no specialist operators. Water and heat do the work.
Load & Seal
Waste is loaded into the sealed spherical pressure vessel. No sorting, no additives — just the raw organic waste stream.
Subcritical Water Hydrolysis
Water is heated to 150–374°C at ≤22.1 MPa inside the reactor. At subcritical conditions, water's ionic constant Kw spikes — driving rapid molecular hydrolysis of proteins, fats, and carbohydrates.
Sterile Outputs
30 minutes later: sterile compost or bio-coal (solid), amino acid-rich liquid fertiliser, and clean effluent. Zero dioxins. Zero fly ash. Three sellable output streams.
What Comes Out
Compost / Bio-coal
Class A compost or ~5,000 kcal/kg solid fuel

The Science
Why Subcritical Water Works Where Other Technologies Fail
Subcritical water hydrolysis exploits a property of liquid water that most waste treatment technologies ignore: between 100°C and 374°C, under sufficient pressure to remain liquid, water's ionic product (Kw) increases by several orders of magnitude. This transforms ordinary water into a highly reactive ionic solvent — capable of breaking peptide bonds in proteins, hydrolysing ester linkages in fats, and cleaving glycosidic bonds in carbohydrates — all without adding acids, alkalis, or enzymes.
The practical consequence is total organic breakdown in 30 minutes. Proteins hydrolyse into free amino acids. Fats saponify into fatty acids and glycerol. Carbohydrates dissolve. Pathogenic organisms — bacteria, viruses, prions — are denatured by the combination of temperature, pressure, and ionic chemistry. The process achieves >99.9999% (6-log) pathogen reduction, the highest level tested under IStAATT protocols for non-incineration medical waste treatment.
Critically, because there is no combustion, there is no formation of dioxins, furans, polycyclic aromatic hydrocarbons, or nitrogen oxides. The sealed pressure vessel prevents any gas release during processing. What enters the vessel as contaminated waste exits as three distinct outputs: a solid fraction (sterile compost or, where plastics are present, high-calorie bio-coal at ~5,000 kcal/kg), an amino acid-rich liquid fertiliser, and clean effluent that typically meets discharge consent standards.
PHANTOM's spherical reactor is fabricated from pharmaceutical-grade SUS 304 stainless steel, rated to ≤22.1 MPa operating pressure. The spherical geometry distributes pressure forces evenly across the vessel wall — a key reason the system requires major maintenance only every 10 years under continuous-cycle operation. A kerosene boiler generates the steam required to reach operating temperature; total fuel cost is approximately £33 (~$42 USD) per 3-tonne cycle, equating to £11–£16 per tonne at rated throughput.
This combination — complete sterilisation, zero harmful emissions, commercially valuable outputs, and low operating cost — is why PHANTOM is being deployed in hospitals, livestock facilities, food processors, and industrial operations across Europe and Asia. It does what incineration does (sterilise and reduce volume) without any of what incineration creates (toxic emissions, carbon liability, planning opposition, hazardous residues).
Common Questions
Frequently Asked Questions
How much does an industrial waste treatment machine cost in the UK?▾
The PHANTOM system is priced at approximately ¥260,000,000 FOB Japan (~£1.37M / ~$1.75M — a rough estimate, specification-dependent). Finance and leasing arrangements are available. For a facility generating 40 tonnes per week, payback is typically achieved within 1.5–3.5 years depending on local disposal costs and output revenue. Use the ROI calculator above for a facility-specific estimate, or see our full industrial waste machine ROI guide.
How long does subcritical water hydrolysis take per cycle?▾
A PHANTOM processing cycle takes approximately 30 minutes of active hydrolysis, with total cycle time including loading and unloading approximately 50 minutes. Each cycle processes up to 3 tonnes of waste. At two cycles per hour, a single unit processes 24–30 tonnes per 12-hour operating day. For the underlying chemistry, see what is subcritical water hydrolysis?
What types of waste can the PHANTOM system process?▾
PHANTOM processes all organic and mixed-plastic waste streams: clinical and infectious waste, PPE, incontinence products, food processing by-products, livestock manure, fish offal, agricultural residues, and most industrial plastics (PET, PE, PP, PS). Glass, metal, stone, and radioactive materials cannot be processed and require pre-separation. For full waste stream compatibility by EWC code, see the industry-specific guides in the Knowledge Base below.
What are the operating costs per tonne?▾
Operating costs are approximately £33 (~$42 USD) per 3-tonne cycle — covering kerosene fuel and utilities — equating to ~£11–£16/tonne at rated throughput. This compares to off-site incineration at £200–£617/tonne for clinical waste or UK landfill tax at £126.15/tonne (2025/26 standard rate). The 10-year maintenance schedule covers boiler inspection and gasket replacement only. Full cost modelling is covered in the medical waste TCO comparison.
Does PHANTOM require an environmental permit to operate on-site in the UK?▾
In England and Wales, on-site clinical waste treatment requires either an Environmental Permit (Standard Rules SR2012 No.9 or bespoke) or a registered exemption under the Environmental Permitting Regulations 2016. The PHANTOM system's IStAATT Level III validation pathway significantly simplifies EA approval. Scotland requires a SEPA Waste Management Licence; Northern Ireland a NIEA permit. The full regulatory pathway is covered in our UK medical waste permits and validation guide.
