Wood Chip Dryer Manufacturer in Spain
See how we dry Wood ChipLooking for wood chip dryer 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 wood chip dryers are engineered to order at STRONGA's Hertfordshire works and shipped to fuel and board producers here, with no commissioned line on local soil yet. Fuel wood chip is graded under EN ISO 17225-4, which sets moisture and property classes so chip can be traded to boilers and CHP plants on a stated specification. Freshly comminuted chip often carries around 50 per cent moisture, which slashes calorific value and invites mould and dry-matter loss in storage; conditioning it to roughly 15 to 20 per cent produces a stable, higher-value fuel that meets the graded classes. National renewable-energy policy under the PNIEC is expanding demand for exactly this kind of graded biomass fuel.

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.

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):
Drying protects both energy content and saleability. Wet chip loses dry matter and calorific value in the pile, so a graded, low-moisture fuel commands a firmer price and stores safely. National policy pulls demand up: the PNIEC targets a large rise in renewables in final energy by 2030, underpinning boiler and CHP appetite for consistent chip. Where the chip displaces gas or coal in an ETS-covered plant, it also avoids an EU carbon allowance near 80 euros per tonne of CO2. Crucially, the drying step must not burn expensive energy: with industrial electricity near 0.12 euros per kWh, FlowDrya's low electrical draw and use of recovered or biomass heat keep the fuel economic. Assumptions: moisture target, heat source and offtake price govern the payback.

Wood Chip Dryer Manufacturer in Spain — FAQ
Do you supply wood chip dryers here?
Yes, from our Hertfordshire factory. We hold no commissioned wood-chip line on local soil yet and will not imply one; the platform is the same continuous-flow FlowDrya proven on our British reference sites.
Why does wood chip need drying?
Fresh chip near 50 per cent moisture has a low calorific value and loses dry matter to mould and self-heating in storage. Drying to roughly 15 to 20 per cent stabilises it and lifts the delivered energy, letting it meet the EN ISO 17225-4 classes.
Which standard grades wood chip fuel?
EN ISO 17225-4 sets the property and moisture classes for graded wood chips, so a dried, documented chip can be sold to boilers and CHP operators on a stated specification. Meeting a defined class also protects the buyer's warranty and keeps combustion behaviour predictable.
How does drying help the carbon case?
When dried chip displaces gas or coal in a plant covered by the EU Emissions Trading System, each tonne avoids a carbon allowance near 80 euros per tonne of CO2, on top of the fuel saving.
Does the dryer run economically on Spanish energy prices?
Yes. With industrial power near 0.12 euros per kWh, FlowDrya's stop-start moving floor draws little electricity and is designed to run on recovered or biomass heat rather than bought-in power.
How is a wood chip 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.
