Drying Solid Recovered Fuel (SRF) with FlowDrya industrial drying system

SRF Dryer Manufacturer in Australia

See how we dry SRF

Looking for SRF dryers manufacturers in Australia? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to Australia — see the regulatory and economic context below.

We manufacture FlowDrya SRF drying plants to order at STRONGA's Hertfordshire factory and ship them to producers here; in the interest of honesty, we operate no documented SRF drying reference in this market yet. Solid recovered fuel is the tightly specified cousin of RDF: to trade it and to have a cement or lime kiln accept it, the fuel must hold a declared class under EN ISO 21640, and a stable low moisture below 15% is what makes the net-calorific-value, chlorine and particle-size classes repeatable. That predictability is exactly what a kiln operator needs before committing to a high thermal-substitution rate under a tightening carbon regime, and it is what turns a variable waste stream into a fuel a Safeguard-covered plant will pay to take.

We supply Australia from our Hertfordshire works — we have no documented SRF installation in Australia yet.

Regulatory context

Waste is regulated by the states and territories rather than by a single national permit, so a plant that stores, treats or dries a waste-derived material is licensed by the relevant state environment regulator — for example under the New South Wales Protection of the Environment Operations Act 1997, administered by the NSW EPA — and most states also apply a waste levy on material sent to landfill, which is the principal lever pushing wet residues toward recovery, drying and reuse.

Under the Commonwealth Recycling and Waste Reduction Act 2020, Australia bans the export of unprocessed waste glass, plastic, paper and tyres; these materials may only be exported once they have been processed into a value-added form, which increases domestic demand for on-shore processing, drying and conversion of waste-derived materials into usable products and fuels.

The Safeguard Mechanism, reformed from 1 July 2023, sets declining emissions baselines for facilities that emit more than 100,000 tonnes of CO2e a year, with those baselines falling by 4.9 per cent each year to 2030; cement kilns, lime plants and other large emitters that exceed their baseline must surrender carbon units, which rewards displacing coal and gas with a dried, waste-derived alternative fuel.

Economic context

State waste levies make disposal expensive: in Victoria the metropolitan levy is AUD 169.79 per tonne for both municipal and industrial waste in 2025-26 (EPA Victoria), one of the higher rates among the states, so every tonne of water or inert material kept out of landfill is a direct and rising saving.

Wholesale electricity spot prices averaged about AUD 83 per megawatt hour across the National Electricity Market in the first quarter of 2025 (AEMO Quarterly Energy Dynamics), so a dryer that runs on recovered process heat and draws little grid power protects the operating margin.

East-coast wholesale gas prices averaged about AUD 13.26 per gigajoule in the first quarter of 2025, a record high for the period (AEMO Quarterly Energy Dynamics), which favours drying systems built around recovered kiln, boiler or process heat rather than bought-in gas or electric heating.

Australian Carbon Credit Units traded at AUD 33.08 on 31 March 2025 (Clean Energy Regulator); a Safeguard facility that exceeds its baseline can surrender ACCUs to cover the excess, so each tonne of coal a dried alternative fuel displaces avoids both the fuel cost and a carbon-unit liability.

There is a real domestic market for waste-derived kiln fuel: Cement Australia's Geocycle operation produces alternative fuel from industrial wastes for its high-temperature cement kilns, reducing the plants' reliance on coal and natural gas — demand that rewards a consistent, dried, high-calorific fuel.

Worked illustration (assumptions stated):

SRF economics reward specification discipline. A producer able to guarantee an EN ISO 21640 class commands a better offtake price than one shipping damp, variable material, and a fuel above 20 MJ/kg widens the pool of kilns willing to burn it. The pull is real: Cement Australia's Geocycle already converts industrial waste into kiln fuel, and Safeguard baselines falling 4.9 per cent a year make every tonne of coal displaced more valuable, with Australian Carbon Credit Units at AUD 33.08 in March 2025 setting the cost of any excess emissions. Because a dryer built around recovered kiln heat beats electric elements at about AUD 83 per megawatt hour, that is the economical route to reach and hold the target class. Assumptions: these are reference prices, not a site quotation.

SRF Dryer Manufacturer in Australia — FAQ

Do you supply SRF dryers here?

Yes. FlowDrya SRF dryers are engineered and assembled in Hertfordshire, factory-tested before shipping, and commissioned on the customer's site with operator training and a full hot test before handover.

How does drying help SRF meet EN ISO 21640?

Moisture drives net calorific value, and an unstable moisture content pushes a batch between classes. By conditioning the fuel to a repeatable low moisture, FlowDrya helps a producer declare and hold a class a kiln operator will accept.

Do you have an SRF installation here?

Not for SRF. Rather than imply a reference we lack, we point customers to our documented bark, digestate and woodchip projects in Britain, which prove the identical drying technology on comparable heterogeneous feedstocks.

How does SRF differ from RDF for a kiln operator?

SRF is the refined, quality-assured grade – sorted, shredded and dried to a declared specification – whereas RDF is a cruder, more variable output. Kiln operators pay more for the predictability a classified fuel brings.

What drives SRF demand here?

A tightening Safeguard carbon regime and rising landfill levies push kilns to replace coal and petroleum coke with a consistent, classified, low-moisture fuel produced on-shore.
