SRF Dryer Manufacturer in the United Kingdom
See how we dry SRFLooking for SRF dryers manufacturers in the United Kingdom? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to the United Kingdom — see the regulatory and economic context below.
We manufacture FlowDrya SRF drying plants to order at STRONGA's Hertfordshire factory and supply them across Britain. Solid recovered fuel is the tightly specified cousin of RDF: to trade and to be accepted by a cement or lime kiln it must hold to a declared class under EN ISO 21640, and a consistent low moisture is what makes the net-calorific-value, chlorine and particle-size classes repeatable. Honesty first: we do not currently operate a documented SRF drying reference in Britain, and we will not pretend otherwise. What we can show are working British FlowDrya lines drying bark, digestate fibre and woodchips, which use the identical hydraulic moving-floor platform an SRF plant is built on.
Supplying the United Kingdom
We supply the United Kingdom from our Hertfordshire works — we have no documented SRF installation in the United Kingdom yet. Our FlowDrya projects in the United Kingdom to date cover other materials:
Regulatory context
Operating a plant that stores, treats or dries a waste-derived or organic material normally requires an environmental permit from the Environment Agency (or the devolved regulator in Scotland, Wales and Northern Ireland); the operator must demonstrate technical competence and comply with the permit conditions.

Exporting waste-derived fuel such as RDF or SRF abroad is controlled under the assimilated Waste Shipments Regulation: most movements to recovery in the EU require prior written notification and consent from all competent authorities (amber-list controls), and the export of domestically derived RDF to non-OECD countries is prohibited.

Solid recovered fuel produced from non-hazardous waste is specified and classified under EN ISO 21640, which assigns classes on net calorific value, chlorine content and mercury content so the fuel can be traded and burned consistently in cement and lime kilns.

Applicable standards: EN ISO 21640, EN ISO 17225-4, PAS 110, PAS 100.
Economic context
Landfill Tax on the disposal of most active waste in England and Northern Ireland is £130.75 per tonne from 1 April 2026 (the lower rate for inert waste is £8.65 per tonne); Scotland and Wales apply aligned devolved rates. The escalating tax is the primary economic driver for diverting material away from landfill.

The median UK gate fee for non-hazardous landfill, excluding Landfill Tax, was £34 per tonne in WRAP's UK Gate Fees Report 2025-26, and median energy-from-waste gate fees rose again across all categories surveyed.

UK manufacturers paid an average of 17.08 pence per kWh for electricity and 3.71 pence per kWh for gas in Quarter 2 2025 (DESNZ Quarterly Energy Prices, September 2025). High industrial electricity prices reward drying equipment that runs on recovered waste heat and minimal electrical power rather than direct electric heating.

Worked illustration (assumptions stated):
SRF economics reward specification discipline. A producer that can guarantee a class under EN ISO 21640 commands a better offtake price than one shipping variable, wet material, and dry fuel that also meets EN ISO 17225-4 solid-biofuel expectations widens the pool of kilns willing to take it. Set against the alternative – Landfill Tax at £130.75 per tonne plus a landfill gate fee around £34 per tonne – even a modest drying cost is easily justified. Because British industrial power is dear at 17.08 pence per kWh while gas sits at 3.71 pence, a dryer designed around recovered heat rather than electric elements is the economical way to hit and hold the target class. Assumptions stated: the prices are national reference figures, not a site quotation.

SRF Dryer Manufacturer in the United Kingdom — FAQ
Do you supply SRF dryers in the United Kingdom?
Yes. FlowDrya SRF dryers are engineered and assembled in Hertfordshire and delivered nationwide, factory-tested before shipping and commissioned on site with operator training and a hot test.
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 under EN ISO 21640 that a kiln operator will accept.
Do you have a British SRF installation?
Not for SRF. Rather than imply a reference we lack, we point customers to our documented bark, digestate and woodchip projects in England and Wales, which prove the same 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 an ISO-classified fuel brings.
Can one plant switch between fuel grades?
Yes. By adjusting residence time and air temperature, a single FlowDrya can condition both coarser RDF and tightly specified SRF, giving a producer flexibility as offtake contracts change.
