Municipal Solid Waste Dryer Manufacturer in New Zealand
See how we dry Solid WasteLooking for MSW dryer manufacturers in New Zealand? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to New Zealand — see the regulatory and economic context below.
FlowDrya solid-waste dryers are built to order at STRONGA's Hertfordshire works and supplied to New Zealand operators handling mixed municipal and commercial residues, though no FlowDrya solid-waste line is yet commissioned in the country. Mixed waste arrives wet and heterogeneous, which is why so much of it is simply buried. Drying the combustible fraction to a low, even moisture strips out the water that makes waste heavy and hard to burn, and turns the residue into a graded refuse- or solid-recovered fuel that a kiln can accept in place of coal. With domestic energy-from-waste still nascent and contested, drying for a kiln-ready fuel is the most practical alternative to the landfill.
Supplying New Zealand
We supply New Zealand from our Hertfordshire works — we have no documented Solid Waste installation in New Zealand yet.
Regulatory context
Disposal is priced through the waste disposal levy set under the Waste Minimisation Act 2008 and administered by the Ministry for the Environment; the levy on municipal (class 1) landfill is NZD 65 per tonne from 1 July 2025, rising to NZD 70 per tonne on 1 July 2026 and NZD 75 per tonne on 1 July 2027, and has been expanded across more landfill classes — the principal lever pushing wet residues toward recovery, drying and reuse rather than burial.

Carbon is priced through the New Zealand Emissions Trading Scheme (NZ ETS), the country's main tool for cutting emissions; a plant that burns coal or natural gas must surrender New Zealand Units for its combustion emissions, so displacing that fossil fuel with a dried, waste-derived or biomass fuel directly reduces the unit liability. The 2026 auction reserve price floor is NZD 71 per unit.

Biosolids applied to land are governed by the beneficial reuse of biosolids standard administered by the Water Services Authority (Taumata Arowai) under the Water Services (Wastewater Environmental Performance Standards) Regulations 2025; a product is graded by stabilisation (Grade A or B, on pathogen reduction) and by contaminant concentration, with only the top stabilisation-and-contaminant grade allowed as a permitted activity without a resource consent — and thermal treatment and drying support that higher stabilisation grade.

Waste-derived and biomass solid fuels are characterised against the European ISO standards that New Zealand laboratories and buyers use in the absence of a bespoke national fuel specification — EN ISO 21640 for solid recovered fuel classification, the EN ISO 17225 series for solid biofuels, and EN ISO 18134 for moisture determination — so a dried fuel can be sold on a documented calorific value and moisture grade.

Economic context
The rising waste disposal levy makes burial expensive: at NZD 65 per tonne for class 1 landfill in 2025 and scheduled to reach NZD 70 per tonne in 2026 and NZD 75 per tonne in 2027 (before gate and transport charges), every tonne of water or inert residue kept out of landfill by drying is a direct and growing saving.

Carbon carries a real cost: New Zealand Units traded on the secondary market around NZD 55.04, against a 2026 auction reserve price floor of NZD 71 (International Carbon Action Partnership), so each tonne of coal or gas that a dried alternative fuel displaces avoids both the fuel bill and an ETS unit liability.

Bought-in energy is dear and getting dearer: industrial electricity and natural-gas prices rose sharply in the year to March 2025 as domestic gas supply tightened (MBIE New Zealand Energy Quarterly), which favours drying systems built around recovered kiln, boiler or process heat rather than grid electricity or bought-in gas.
Worked illustration (assumptions stated):
Landfill is the cost drying displaces. The class 1 waste levy sits at NZD 65 per tonne in 2025 and is legislated to reach NZD 70 in 2026 and NZD 75 in 2027, on top of gate and haulage charges, so every tonne diverted into fuel is a rising saving. Carbon compounds it: with New Zealand Units near NZD 55.04 against a 2026 auction floor of NZD 71, a dried fuel that displaces coal in a kiln also trims an ETS unit liability. Because the water weight is removed, the fuel freights cheaply, and running the dryer on recovered process heat keeps conversion economical. Diverting material also advances the resource-recovery goals the levy is designed to fund. Assumptions: gate fees, offtake and carbon exposure are site-specific.

Municipal Solid Waste Dryer Manufacturer in New Zealand — FAQ
Do you supply solid-waste dryers in New Zealand?
Yes, from Hertfordshire. No solid-waste line is commissioned in the country yet, so we describe the platform by reference to the waste and biomass dryers we already run in Britain.
Why dry mixed solid waste?
Water makes waste heavy, hard to burn and impossible to grade. Removing it lifts the calorific value and turns the combustible fraction into a specified fuel a kiln can accept instead of coal.
What happens to the dried fuel?
It is classified as a refuse- or solid-recovered fuel and offered to high-temperature industrial or cement kilns cutting their coal use, or to any emerging energy-from-waste capacity.
How does drying cut disposal cost?
It keeps combustible material out of a rising landfill levy and reduces the tonnage hauled and buried, replacing a disposal charge with a fuel that carries value.
Does it help with carbon costs too?
Yes. By displacing coal in a kiln, a dried waste-derived fuel lowers the ETS unit liability the receiving plant would otherwise face, on top of avoiding the levy.
How does drying change how much waste ends up buried?
By removing water and pulling the burnable portion into a usable fuel, drying shrinks both the mass and the volume that reach a landfill. Less tonnage buried means lower gate charges, longer landfill life and fewer truck movements to the tip.
What happens to the non-combustible fraction?
Metals, glass and inert grit separated before or after drying can be recycled or used as aggregate, so the process complements upstream sorting rather than replacing it. Drying simply captures the energy locked in the wet organic and paper material that would otherwise rot in the ground.
