RDF Dryer Manufacturer in Spain
See how we dry RDFLooking for RDF dryers manufacturers in Spain? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to Spain — see the regulatory and economic context below.
FlowDrya RDF dryers are engineered to order at STRONGA's Hertfordshire works and shipped to refuse-fuel producers here, and we hold no commissioned line on home soil to point to. Refuse-derived fuel is one of the materials most shaped by domestic policy: Ley 7/2022 caps the share of municipal waste that may be landfilled at 10 per cent by 2035 and taxes burial, so the combustible fraction has to be recovered instead. A cement kiln or waste-to-energy plant will only sign for a prepared, low-moisture fuel; shredded RDF often arrives above 55 per cent moisture and is refused wet. Conditioning it below 20 per cent lifts and steadies the calorific value until a licensed off-taker will accept it, and the hydraulic moving floor copes with the coarse, contrary mix.

Regulatory context
Ley 7/2022, de 8 de abril, de residuos y suelos contaminados para una economía circular is the backbone of Spanish waste law. It transposes EU Directive 2018/851, entrenches the waste hierarchy — prevention, preparation for re-use, recycling, other recovery including energy, and disposal last — and sets binding targets: at least 55 per cent of municipal waste prepared for re-use and recycled by 2025, rising to 65 per cent by 2035, with no more than 10 per cent of municipal waste sent to landfill by 2035. Drying a wet residue into a fuel or a soil product is a recovery route ranked above burial, and it helps operators meet those diversion goals.

Since 1 January 2023 Spain applies a state tax on the deposit of waste in landfill and on its incineration and co-incineration (impuesto sobre el depósito de residuos en vertederos, la incineración y la coincineración de residuos), created by Ley 7/2022 and ceded to the autonomous communities, which may raise the rates. The state rate for non-hazardous municipal waste sent to landfill is 40 euros per tonne; municipal waste incinerated is taxed at 20 euros per tonne for disposal or 15 euros per tonne for energy recovery; waste co-incinerated in cement kilns and similar plants is taxed at 0 euros per tonne. The structure deliberately rewards diverting a prepared fuel to co-processing over burial.

Compost and other organic amendments sold to farmers in Spain must comply with Real Decreto 506/2013 sobre productos fertilizantes, which fixes the permitted raw materials, the pathogen limits and the heavy-metal classes A, B and C, and requires registration in the Registro de Productos Fertilizantes before a product can be placed on the market. A dried, stabilised material holds those quality limits far more readily than a wet, actively degrading feedstock.

Economic context
The waste tax makes disposal the expensive option and co-processing the cheap one. Burying a tonne of non-hazardous municipal waste carries a state charge of 40 euros, while a tonne co-incinerated as fuel in a cement kiln is charged 0 euros — before an autonomous community adds its own surcharge. Every tonne of wet residue turned into a dried, kiln-ready fuel therefore side-steps a growing burial cost while creating a saleable product.

Spanish cement kilns are a large and growing outlet for waste-derived fuel. Oficemen data reported by the sector show it substituted 40.9 per cent of its fossil fuel with alternative fuels in 2023, recovering about 1.08 million tonnes of waste as fuel and avoiding roughly 1.2 million tonnes of CO2 — yet Spain still trails the leading northern-European producers, leaving substantial room for more co-processing. A dried, specification-consistent fuel with a low, even moisture is exactly what those kilns will accept.

Conversion cost matters. Eurostat data put the price of electricity for medium-sized Spanish industrial consumers at about 0.12 euros per kilowatt-hour, so boiling water off with resistance heating is uneconomic; a dryer that runs on recovered process, exhaust or kiln heat and very little electrical power is what keeps drying viable.

Heavy industry also pays for carbon under the EU Emissions Trading System, where allowances traded around 80 euros per tonne of CO2 in late 2025 (83.79 euros on 15 December 2025). Every tonne of coal or petroleum coke a dried waste- or biomass-derived fuel displaces in a kiln avoids a real and rising per-tonne carbon cost on top of the fuel saving.

Worked illustration (assumptions stated):
Two prices push refuse toward a dried fuel. Burial is dear – the state tax charges 40 euros on every tonne of non-hazardous municipal waste sent to landfill – while the same tonne co-incinerated as fuel in a cement kiln is charged 0 euros, so diverting it avoids a rising cost and earns a product. The outlet is real and expanding: kilns here substituted 40.9 per cent of their fossil fuel with alternative fuels in 2023 and still trail northern-European leaders. Displacing coal or petcoke also dodges an EU carbon allowance near 80 euros per tonne of CO2, while firing the dryer on recovered kiln or pre-calciner heat rather than power at 0.12 euros per kWh keeps conversion cheap. Assumptions: offtake terms, chlorine limits and available heat move the payback.

RDF Dryer Manufacturer in Spain — FAQ
Do you supply RDF dryers here?
Yes, from our Hertfordshire factory. We hold no commissioned RDF line on home soil yet and will not imply one; the platform is the same continuous-flow FlowDrya proven on our British reference sites.
How does Ley 7/2022 drive RDF drying?
The waste law caps municipal landfilling at 10 per cent by 2035 and taxes burial, so the burnable fraction must be recovered. Drying stabilises it and raises calorific value, turning a residue with nowhere to go into a fuel a cement kiln will take.
Why is the landfill-versus-kiln tax gap important?
Sending non-hazardous municipal waste to landfill is taxed at 40 euros per tonne, but co-incineration in a kiln is taxed at 0 euros. That gap rewards turning wet refuse into a dried, kiln-ready fuel rather than burying it.
How large is the cement outlet?
Substantial and growing. Kilns replaced 40.9 per cent of their fossil energy with alternative fuels in 2023 and lag the northern-European leaders, so a reliable, dried refuse-derived fuel has real room to expand in place of coal and petcoke.
Does the FlowDrya cope with coarse, mixed RDF?
Yes. The hydraulic moving floor tumbles and conveys an oversized, contrary mix without the blockages that beset auger and belt systems, drying the material evenly across the deck.
How is an RDF plant shipped and commissioned from the UK?
Each dryer is fully assembled and factory-tested at our works, then dismantled for freight. On arrival it is reassembled, connected to the site's heat supply and brought online through a structured start-up, shutdown and supervised trial before handover, with operator training included.
