RDF Dryer Manufacturer in the United States
See how we dry RDFLooking for RDF dryers manufacturers in the United States? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to the United States — see the regulatory and economic context below.
FlowDrya RDF drying plants are engineered and built to order at the STRONGA works in Hertfordshire, England, and shipped to American customers, though we say plainly that no FlowDrya RDF line is yet documented on US soil. Refuse-derived fuel sits at the heart of American alternative-fuel policy: shredded municipal residue frequently arrives above 55% moisture, and cement kilns and waste-to-energy plants reward a lighter, drier, higher-calorific feed. Conditioning the fuel below 20% moisture raises net calorific value from under 10 MJ/kg toward roughly 18 MJ/kg, and that repeatability is what helps a fuel clear EPA's Non-Hazardous Secondary Material test and hold steady combustion in a kiln burner.
Supplying the United States
We supply the United States from our Hertfordshire works — we have no documented RDF installation in the United States yet.
Regulatory context
Non-hazardous solid waste is regulated under Subtitle D of the federal Resource Conservation and Recovery Act (RCRA): open dumping is banned and municipal solid waste landfills must meet the minimum national criteria of 40 CFR Part 258, but the individual states run the permitting programs and may set stricter rules, so the requirements a drying or waste-processing plant faces vary from state to state.

Whether a waste-derived fuel such as RDF or SRF counts as a legitimate fuel or as a discarded 'solid waste' when burned in a cement kiln or waste-to-energy unit is decided by EPA's 2011 Non-Hazardous Secondary Material rule, and that classification sets which Clean Air Act (MACT) emission standards the combustion unit must meet; a consistent, low-moisture, well-specified fuel is central both to qualifying and to stable combustion.

Economic context
US landfill tipping fees have climbed year on year — the latest national survey by the Environmental Research & Education Foundation (EREF) put the average at $62.28 per ton, roughly 10% up on the prior year, and large or private landfills charge appreciably more — so avoiding disposal is a growing cost saving.

US industrial customers paid an average of roughly 8.29 cents per kWh for electricity in 2025 (EIA Electric Power Monthly, Table 5.6.A) — cheaper than in Europe but still well above the cost of recovered process heat, so a dryer that runs on waste heat and draws little grid power protects the operating margin.

US industrial natural gas is inexpensive by world standards — recent EIA data put it at $4.07 per thousand cubic feet — which favours drying systems designed around gas-fired or biomass-fired heat, or recovered kiln and boiler exhaust, rather than electric heating.

Worked illustration (assumptions stated):
The domestic argument for drying RDF turns on avoided disposal and cheap heat. With the national average landfill tipping fee at $62.28 per ton – and higher again at large private sites – every ton diverted into kiln fuel earns its keep. Drying lifts the calorific value so each ton displaces more coal or petroleum coke, while a dryer fed by recovered pre-calciner exhaust rather than the grid sidesteps industrial electricity at 8.29 cents per kWh; natural gas at $4.07 per thousand cubic feet, or spare kiln heat, is the far cheaper way to boil off water. Assumptions stated: these are national averages, and your gate fee, heat source and cement-plant offtake govern the true payback.

RDF Dryer Manufacturer in the United States — FAQ
Do you supply RDF dryers in America?
We do. Every FlowDrya RDF dryer is manufactured to order in Hertfordshire, factory-tested, then shipped and commissioned on the customer's site; installation is typically completed within days, followed by operator training and a full hot test before handover.
How does drying help RDF qualify as a fuel here?
EPA's Non-Hazardous Secondary Material rule decides whether a burned material is a legitimate fuel or a discarded waste, which in turn sets the Clean Air Act standards a kiln must meet. A dry, consistent, well-specified fuel supports that classification and burns predictably.
Do you have a US RDF installation yet?
No – and we will not imply one. Our nearest documented FlowDrya projects dry bark, digestate fibre and woodchips in Britain, and each runs the same PulseWave moving-floor platform an American refuse-fuel plant would receive.
Which buyers take dried RDF domestically?
Cement and lime kilns and waste-to-energy plants are the usual homes, all preferring a lighter, higher-calorific, uniform feed that steadies the burner, raises the thermal-substitution rate and cuts rejected loads.
Why does moisture matter so much for calorific value?
Water carried into the burner is boiled off before any useful heat is released, so damp residue near 55% moisture wastes energy. Drying below 20% concentrates the combustible fraction and lifts calorific value toward 18 MJ/kg.
How is a plant shipped and commissioned from the UK?
The dryer is fully assembled and tested at the factory, then disassembled for freight. On arrival it is reassembled, connected to the site's heat source and brought online through a structured start-up, shutdown and supervised trial run before handover.
