Frequently Asked Questions

UHTMG — Ultra-High-Temperature, Modular Gasification Technology — uses a plasma arc to generate temperatures exceeding 10,000°C inside a sealed chamber. At these temperatures, any organic material is completely broken apart at the molecular level. The output is clean synthesis gas (syngas) — hydrogen and carbon monoxide — plus an inert, vitrified slag. No ash, no dioxins, no residue. The technology has been operating commercially at industrial scale globally for decades. Full deployment history in our Track Record section.

Traditional waste-to-energy projects commit £100M+ of capital before the economics are validated. NZP inverts that. Our software platform lets you input your actual waste data and see the full commercial model — yields, revenue mix, payback period, carbon credits — before a single pound is committed. Only when the numbers make sense do you move to the investment phase, with offtake partners already in place.

The platform supports hundreds of feedstock profiles — municipal solid waste (MSW), industrial waste, agricultural residues, spent grain, tyres, medical waste, PFAS-contaminated materials, and mixed industrial streams. Unlike conventional gasification, UHTMG requires no pre-sorting, no pre-treatment, and no specific calorific value. You bring your waste stream; the model handles the chemistry.

PFAS "forever chemicals" contain carbon-fluorine bonds — the strongest bonds in organic chemistry. Breaking them requires sustained temperatures above 10,000°C. Every competing technology — incineration, pyrolysis, hydrothermal processing — falls short. Only plasma arc gasification operating at UHTMG temperatures completely mineralises PFAS compounds into stable, inert substances. This is a rapidly growing regulatory obligation affecting thousands of industrial operators across 50+ countries.

The syngas produced by UHTMG is a configurable feedstock. Depending on the project economics and offtake agreements, it can be converted into: green hydrogen (via separation), sustainable aviation fuel or SAF (via Fischer-Tropsch synthesis), ammonia (via Haber-Bosch), renewable natural gas, or direct electricity generation. The NZP platform models all pathways simultaneously so you can compare the economics of each output scenario before committing.

NZP structures projects in four phases: (1) Software modelling — validate your waste stream and commercial case using our platform; (2) Pilot — deploy a modular unit at demonstration scale to prove yield with real feedstock; (3) Commercial — scale to full commercial throughput with offtake already contracted; (4) Expansion — replicate the model across additional sites or waste streams. Capital is deployed at each phase gate only when commercial milestones are met.

Core equipment uses submerged arc furnace technology — the same globally proven supply chain as the steel industry, with no single-supplier dependency. Fischer-Tropsch and Haber-Bosch synthesis partners are in place for downstream conversion. Offtake is contracted with a major energy partner (not named publicly at this stage). The full back-end of the value chain is covered — NZP brings the waste stream, the software, and the commercial architecture. The full ecosystem map covers EPC, synthesis, equipment, offtake and capital partners.

Whatever your offtake spec requires. NZP does not lead with a single purity headline — we configure the membrane and pressure-swing adsorption (PSA) train to your contracted grade. Industrial (95–99.5%) is sufficient for most welding, metallurgy and chemical manufacturing applications. Chemical grade (99.9% / 3.0) suits ammonia and refining. ISO 14687 fuel-cell grade (≥99.97%) covers FCEV and stationary fuel cells. UHP (99.999% / 5.0) is available for lab and specialty chemicals. Stepping from Industrial to Chemical grade typically adds approximately $0.20–0.70/kg OPEX and $0.75–1.0M CAPEX. The full delta is modelled before any commitment.

For ammonia, fertiliser, chemical and merchant H₂ producers running steam methane reformers (SMR) or autothermal reformers (ATR), NZP supplies spec-compliant hydrogen alongside your existing reformer — partial displacement, never replacement. You retain operational control. NZP carries feedstock, logistics and availability risk. The customer contracts on €/kg, uptime SLA, and purity grade — the same shape as a merchant gas deal you have already signed before. We do not target oil majors or refineries with this model. Full detail on the Sidecar Model page.

NZP's submerged arc plasma system operates within the same envelope as the global electric arc furnace (EAF) supply chain underwriting 200+ commercial steelmaking deployments: availability target greater than 95%, tap-to-tap cycle under 45 minutes, electrode consumption 1.5–2.5 kg/t. Energy demand is modelled across high / average / low scenarios; we default to the conservative high (300–500 kWh/t band) for early-stage modelling. Once a stable operating point is established post-commissioning, energy demand falls toward the lower end of the band. Full sensitivity analysis is delivered with every modelling run.

UK landfill tax is £126.15/t (2025) — a roughly 22% jump on the historical trend. EfW gate fees are rising on tightening capacity and carbon pass-through. Most mid-tier UK collectors operate fixed-price or semi-indexed customer contracts but face spot-priced disposal — revenue (fixed) minus disposal cost (floating, rising) is a margin-compression mechanism. Vertically integrated operators (Biffa, Veolia) hedge by owning landfill or EfW capacity; asset-light brokers and regional collectors do not. Multiple councils (Birmingham, Croydon, Thurrock) have issued Section 114 notices. Renewi exited UK municipal waste at a €57M loss. NZP changes the arithmetic: feedstock that costs you to dispose of becomes feedstock that pays.
