Bark Dryer Manufacturer in Spain
See how we dry BarkLooking for bark 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 bark dryers are built to order at STRONGA's Hertfordshire works and shipped to sawmills and biomass producers here, with no commissioned line on local soil yet. Bark stripped at the mill is bulky and wet, often around 56 per cent moisture, which makes it costly to transport and marginal as a fuel or a horticultural product. Drying it to a low, even moisture concentrates the energy, stabilises it for storage and opens outlets as a graded biomass fuel, a landscaping mulch or a panel-board raw material. Ley 7/2022, which taxes disposal and drives organic residues toward recovery, strengthens the case for valorising bark rather than dumping it.

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):
Bark's economics turn on transport, disposal and fuel value. Wet bark is heavy, so drying cuts the tonnage hauled and the loads charged; residue sent to landfill also carries the 40-euro-per-tonne state tax on non-hazardous waste, which valorisation avoids. As a fuel, dried bark can displace gas or coal, and where it does so in an ETS-covered plant it avoids an EU carbon allowance near 80 euros per tonne of CO2. The cement sector, which substituted 40.9 per cent of its fossil fuel with alternative fuels in 2023, is one more outlet for a graded biomass fraction. With industrial power near 0.12 euros per kWh, the dryer is designed to run on recovered mill or process heat. Assumptions: end-market, heat source and haulage distance govern the payback.

Bark Dryer Manufacturer in Spain — FAQ
Do you supply bark dryers here?
Yes, from our Hertfordshire factory. We hold no commissioned bark 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 dry bark?
Fresh bark near 56 per cent moisture is heavy to transport and poor as a fuel. Drying concentrates the energy, stabilises it for storage and opens markets as biomass fuel, mulch or board feedstock.
What can dried bark be sold as?
A graded biomass fuel for boilers and kilns, a horticultural or landscaping mulch, or a raw material for panel board. A low, even moisture is what each of those buyers requires. Uniform, dried bark also resists fungal breakdown on the retail shelf and blends cleanly into growing media.
How does the waste tax affect bark?
Bark sent to landfill as non-hazardous waste is taxed at 40 euros per tonne; drying and valorising it avoids that charge while turning a by-product into a saleable material.
Does the FlowDrya cope with bulky, fibrous bark?
Yes. The hydraulic moving floor conveys and tumbles coarse, fibrous material on a deep bed, drying it evenly without the bridging that troubles auger and belt systems.
How is a bark 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.
