Municipal Solid Waste Dryer Manufacturer in Spain
See how we dry Solid WasteLooking for MSW 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 solid waste dryers are engineered to order at STRONGA's Hertfordshire works and shipped to waste managers and recyclers here, with no commissioned line on local soil yet. Mixed municipal and commercial solid waste is wet and heterogeneous, which depresses its calorific value and its recyclable yield. Drying the material before or after mechanical sorting concentrates the combustible fraction, improves separation of recyclables and produces a lighter, higher-value residue that can be recovered as fuel. This matters because Ley 7/2022 caps the municipal waste that may be landfilled at 10 per cent by 2035 and taxes burial, forcing operators to squeeze recovery and recycling out of every tonne rather than sending it to a vertedero.

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):
The economics follow directly from the landfill cap and tax. Burying a tonne of non-hazardous municipal waste is taxed at 40 euros, while the combustible fraction, once dried, can be co-incinerated as fuel at a tax of 0 euros – a gap that rewards recovery over burial. Cement kilns, which substituted 40.9 per cent of their fossil fuel with alternative fuels in 2023, are the natural outlet for that fuel, and displacing coal avoids an EU carbon allowance near 80 euros per tonne of CO2. Drying also lifts recyclable recovery, adding value before disposal. With industrial power near 0.12 euros per kWh, the plant is built to run on recovered heat rather than electricity. Assumptions: waste composition, heat source and offtake govern the payback.

Municipal Solid Waste Dryer Manufacturer in Spain — FAQ
Do you supply solid waste dryers here?
Yes, from our Hertfordshire factory. We hold no commissioned solid-waste line on local 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 change solid-waste handling?
It caps the municipal waste that may be landfilled at 10 per cent by 2035 and taxes burial, so operators must recover fuel and recyclables from every tonne. Drying the waste raises both the recyclable yield and the calorific value of the residual fuel.
Why does drying help recycling and recovery?
Water depresses calorific value and gums up sorting. Removing it concentrates the combustible fraction, improves the separation of recyclables and produces a lighter, higher-value residue that a kiln or energy-from-waste plant will accept. Drier streams also jam conveyors less and let optical and magnetic separators read materials far more accurately.
What is the disposal-versus-recovery cost gap?
Landfilling non-hazardous municipal waste is taxed at 40 euros per tonne, while co-incinerating the dried combustible fraction is taxed at 0 euros. That gap makes recovery the cheaper route.
Where does the recovered fuel go?
Chiefly cement kilns, which substituted 40.9 per cent of their fossil fuel with alternative fuels in 2023, plus energy-from-waste plants – both preferring a dried, consistent, higher-calorific feed. Gasification and pyrolysis operators form a smaller but emerging third outlet.
How is a solid waste 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.
