Industrial Drying Plant Manufacturer in Spain
Explore the technologyLooking for drying plants 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 biomass drying plants are engineered and built to order at STRONGA's Hertfordshire works and shipped to producers here, and we say plainly that no FlowDrya line is yet commissioned on local soil. A biomass drying plant conditions wet organic feedstocks – wood chip, bark, agricultural residues, screened biomass fractions – into a stable, graded, low-moisture fuel for boilers, CHP and kilns. Wet biomass burns poorly, degrades in storage and cannot be sold on a documented calorific value; drying to a controlled moisture fixes all three. National policy is behind this: the PNIEC is steering Spanish energy toward renewables, and Ley 7/2022 is diverting organic residues away from landfill toward recovery.
Supplying Spain
We supply Spain from our Hertfordshire works — we have no documented FlowDrya installation in Spain yet.
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.

Since 16 July 2022 the EU Fertilising Products Regulation (EU) 2019/1009 has offered an alternative, harmonised route: a conforming compost or digestate-derived product can carry the CE marking (marcado CE) and circulate across the EU, coexisting with the national Real Decreto 506/2013 route. Either way, drying to a controlled, low moisture underpins the consistency and safety a marketable soil product must demonstrate.

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.

National energy policy pulls the same way: Spain's Plan Nacional Integrado de Energía y Clima (PNIEC 2023-2030) targets a large rise in renewables in final energy consumption by 2030 and dedicated biomass capacity, underpinning demand for a graded, low-moisture biomass fuel.

Worked illustration (assumptions stated):
The plant earns its keep three ways. It turns residues that would otherwise be taxed on burial – 40 euros per tonne for non-hazardous municipal waste sent to landfill – into a saleable, storable fuel. It feeds a market that policy is expanding, with the PNIEC targeting a large rise in renewables in final energy by 2030. And where the fuel displaces coal or gas in an ETS-covered plant, it avoids an EU carbon allowance near 80 euros per tonne of CO2. Because the drying step itself must stay cheap against industrial power near 0.12 euros per kWh, FlowDrya's hydraulic moving floor uses far less electricity than continuously running belt dryers and is built to run on recovered heat. Assumptions: feedstock, heat source and offtake govern the payback.

Industrial Drying Plant Manufacturer in Spain — FAQ
Do you supply biomass drying plants here?
Yes, from our Hertfordshire factory. We hold no commissioned line on local soil yet and will not imply one; the platform is the same continuous-flow FlowDrya proven on our British reference sites.
What feedstocks can a FlowDrya biomass plant dry?
Wood chip, bark, sawdust, agricultural and screened biomass residues and similar wet organics. The deep-bed moving floor handles varied particle sizes and dries them to a uniform, graded moisture.
Why dry biomass at all?
Wet biomass has a low calorific value, loses dry matter to mould and self-heating in storage and cannot be traded on a documented specification. Drying to a controlled moisture stabilises the fuel and lifts its delivered energy.
How does policy support biomass fuel here?
The PNIEC is expanding renewables in the energy mix, while Ley 7/2022 diverts organic residues from landfill toward recovery. Both underpin demand for a graded, dried biomass fuel.
Is the drying plant economic given energy prices?
Yes. With industrial electricity near 0.12 euros per kWh, FlowDrya's stop-start operation draws little power and is designed to run on recovered process or biomass heat, so drying does not eat the fuel's value.
How is a biomass 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.
