Drying Solid Recovered Fuel (SRF) with FlowDrya industrial drying system

SRF Dryer Manufacturer in Italy

See how we dry SRF

Looking for SRF dryers manufacturers in Italy? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to Italy — see the regulatory and economic context below.

FlowDrya SRF dryers are built to order at STRONGA's Hertfordshire works and supplied to producers here, with no commissioned line on home soil yet. Solid recovered fuel is the graded, specified cousin of RDF, classified under EN ISO 21640 on net calorific value, chlorine and mercury so it can be traded and burned consistently in cement and lime kilns. In this market a fuel to specification can leave the waste regime as Combustibile Solido Secondario under article 184-ter of Decreto Legislativo 152/2006 and the Decreto Ministeriale 22/2013. That end-of-waste status only holds if the moisture is low and repeatable: conditioning the feedstock below 15 per cent lifts net calorific value above 20 MJ/kg and lets the fuel be sold against a documented class.

Regulatory context

Italian waste law is codified in the Testo Unico Ambientale, Decreto Legislativo 152/2006. Article 179 fixes the waste hierarchy that every operator and authority must follow: prevention first, then preparation for re-use, recycling, other recovery including energy recovery, and disposal only as a last resort. Turning a wet residue into a fuel or a stabilised soil product is a recovery route the code ranks above burial, so drying supports the legal duty to move waste up that hierarchy.

Decreto Legislativo 36/2003 on landfills, overhauled by Decreto Legislativo 121/2020 to transpose EU Directive 2018/850, drives waste away from burial. It requires that by 2035 no more than 10 per cent of municipal waste is sent to landfill, and from 2030 it bans landfilling waste suitable for recycling or other recovery. Because burial is being closed off, the combustible and organic fractions must instead be recovered as fuel or soil products, which is a direct driver for drying wet residues in this market.

Combustibile Solido Secondario, the Italian solid recovered fuel, has a dedicated end-of-waste regime. Under article 184-ter of Decreto Legislativo 152/2006 and the Decreto Ministeriale 22/2013 (CSS-Combustibile), a solid fuel produced from non-hazardous waste to defined specifications ceases to be waste and may be burned as a product in cement kilns, power plants, lime works and steel mills. A low, repeatable moisture is what lets a fuel hold the specification that end-of-waste status and a licensed off-taker require.

Compost and other soil improvers sold to Italian farmers must comply with the national fertiliser law, Decreto Legislativo 75/2010, which defines the permitted amendment categories such as ammendante compostato verde and ammendante compostato misto, sets their chemical, physical and hygiene requirements, and requires registration before a product is placed on the market. A dried, stabilised material holds those pathogen and contaminant limits far more readily than a wet feedstock.

Economic context

The Italian cement industry is a large but under-used outlet for waste-derived fuel. Industry data reported by the sector put thermal substitution with alternative fuels such as CSS at just over 20 per cent, against a European average near 47.7 per cent and leaders such as Austria above 81 per cent. That gap is a real market opportunity: kilns are technically ready to burn far more prepared fuel, and a dried, specification-consistent CSS with a low, even moisture is exactly what they need to close it.

Burying waste carries a regional tax. The tributo speciale per il deposito in discarica, the ecotassa established by Legge 549/1995, is levied on every tonne sent to landfill, up to a statutory maximum of 25.82 euros per tonne for municipal solid waste, set by each region within the national limits. Every tonne of wet residue dried into a recoverable fuel or a saleable soil product avoids that charge while creating a product with a market.

Heavy industry also pays for carbon under the EU Emissions Trading System. Allowances traded around 83 euros per tonne of CO2 in mid-2026, touching about 85 euros, well below the 105.73-euro record of February 2023 but a real and rising charge. Every tonne of coal or petroleum coke that a dried waste- or biomass-derived fuel displaces in a kiln avoids that per-tonne carbon cost on top of the fuel saving.

Italian industry pays some of the highest energy prices in Europe. Eurostat data reported for 2025 put the final electricity price for non-household consumers in Italy 24.1 per cent above the euro-area average, a competitiveness penalty on the national production system. Boiling water off with bought-in electricity is therefore uneconomic; a dryer that runs on recovered process, exhaust or kiln heat and very little electrical power is what keeps drying viable.

Across the European Union, business electricity averaged about 0.1837 euros per kilowatt-hour and gas about 0.0605 euros per kilowatt-hour in 2025, and Italian users sit above those averages. Those prices make electric drying the wrong choice and reward a dryer designed to use spare kiln, exhaust or biomass heat rather than grid power.

Worked illustration (assumptions stated):

The economics rest on a documented grade and an under-used market. Burying the combustible fraction is taxed – the ecotassa reaches 25.82 euros per tonne – while a graded fuel earns an offtake. Italian cement kilns substitute just over 20 per cent of their thermal energy with alternative fuels, far below the European average near 47.7 per cent, and they want the tightest, most consistent fuels first, so a graded CSS earns a firmer price than a crude shred. Displacing coal also avoids an EU carbon allowance near 83 euros per tonne of CO2. Because Italian industrial electricity sits 24.1 per cent above the euro-area average, the honest route to a low moisture is recovered kiln or exhaust heat, never resistance heating. Assumptions: chlorine limits, class targets and heat source govern the payback.

SRF Dryer Manufacturer in Italy — FAQ

Do you supply SRF dryers here?

Yes, from our Hertfordshire factory. We hold no commissioned SRF line on home soil yet and will not imply one; the platform is the same continuous-flow FlowDrya proven on our British reference sites.

What is the difference between SRF and RDF?

SRF is a graded, specified fuel classified under EN ISO 21640 on calorific value, chlorine and mercury; RDF is a cruder, more heterogeneous shred. FlowDrya dries both, but SRF's tighter specification makes a low, repeatable moisture essential.

What is Combustibile Solido Secondario?

CSS is the domestic solid recovered fuel that, under article 184-ter of Decreto Legislativo 152/2006 and the Decreto Ministeriale 22/2013, ceases to be waste once it meets specification and can be burned as a product in cement kilns, power plants and lime works.

What moisture and calorific value does SRF need?

Buyers want a low, consistent moisture – typically below 15 per cent – so net calorific value can hold above 20 MJ/kg. FlowDrya is configured to the moisture the fuel class demands.

How does the low cement substitution create opportunity?

Kilns here substitute just over 20 per cent of their thermal energy with alternative fuels against a European average near 47.7 per cent, so a graded, dried CSS has substantial room to expand in place of coal.

How is an SRF 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.
