Wood Chip Dryer Manufacturer in the United States
See how we dry Wood ChipLooking for wood chip dryer 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 woodchip drying plants are built to order at STRONGA's Hertfordshire works and supplied to American customers, and we are candid that no US woodchip line is documented yet. Dry, uniform chip burns cleaner and hotter in biomass boilers, combined-heat-and-power units and district-energy plants, and a low, even moisture is what lets a producer meet the woodchip classes of EN ISO 17225-4. Whether the feed is virgin forestry residue, sawmill chip or arboricultural arisings, FlowDrya's moving-floor bed and PulseWave agitation tumble the material so it dries evenly instead of sitting wet in a static heap, while sub-deck screening lifts out fines and grit during the drying pass.

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.

There is no single federal compost standard; instead, marketable compost quality is demonstrated through the US Composting Council's Seal of Testing Assurance (STA) Certified Compost program, which uses the TMECC test methods and is referenced by a growing number of state and municipal purchasing specifications.

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):
For wood chip the sum is heat displaced against heat spent. Dry chip meeting EN ISO 17225-4 lets a boiler run at rated output and displaces bought-in fuel, whereas wet chip forces the boiler to evaporate water rather than deliver useful heat. FlowDrya is built to take its drying energy from a boiler flue, a biomass furnace or a CHP jacket rather than the grid, which matters when industrial electricity averages 8.29 cents per kWh against natural gas at $4.07 per thousand cubic feet. On-farm and rural producers can also offset the capital outlay through a USDA REAP grant covering up to 50% of a project, up to $1 million. Assumptions: national average prices; your fuel contract sets the real return.

Wood Chip Dryer Manufacturer in the United States — FAQ
Do you supply wood chip dryers in America?
Yes. Every FlowDrya is engineered and assembled at STRONGA's Hertfordshire factory, factory-tested, then shipped and commissioned on the customer's site with operator training before handover.
What moisture standard should dried wood chip meet?
Woodchip for combustion is classified under EN ISO 17225-4. A stable low moisture keeps a batch within its declared class, which is what boiler operators and fuel buyers require for predictable output.
Do you have a US wood chip installation?
Not yet, and we will not imply one. Our documented woodchip, bark and digestate lines are in Britain, all running the same FlowDrya moving-floor technology a US project would use.
Which sectors buy dried wood chip domestically?
District-energy schemes, commercial and institutional biomass boilers, poultry and greenhouse heating, and pellet mills all favour a high-energy chip that ignites readily and stores without composting or fungal spoilage.
Can FlowDrya handle arboricultural arisings as well as forestry chip?
Yes. The moving-floor bed copes with the variable particle sizes and contamination typical of tree-surgery arisings, screening fines beneath the deck while the coarser chip continues drying above.
Does dry chip improve boiler efficiency?
Markedly. Less water to evaporate means more of the fuel's energy reaches the heat load, cutting consumption, ash and emissions while steadying combustion for automated feed systems.
