SRF Dryer Manufacturer in Brazil
See how we dry SRFLooking for SRF dryers manufacturers in Brazil? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to Brazil — see the regulatory and economic context below.
FlowDrya SRF dryers are engineered to order at STRONGA's Hertfordshire works and supplied to fuel producers here, though no FlowDrya SRF line is documented in the country yet. Solid recovered fuel is a graded, quality-controlled fuel classified against EN ISO 21640, and moisture is one of the properties that fixes its class; a wet SRF cannot hold a grade a cement kiln will accept. Drying the fuel to a low, even moisture lifts and stabilises its calorific value so it can be co-processed in place of coal – a route the cement sector's CONAMA co-processing rules already license – and sold on a documented specification.
Supplying Brazil
We supply Brazil from our Hertfordshire works — we have no documented SRF installation in Brazil yet.
Regulatory context
The National Solid Waste Policy (Política Nacional de Resíduos Sólidos, Lei 12.305/2010) is the framework statute for waste in Brazil. It fixes a binding order of priority — non-generation, reduction, reuse, recycling, treatment and only then the environmentally adequate final disposal of the residual rejects — and expressly recognises energy recovery from waste, so a drying-and-recovery operation that turns wet residue into a fuel or a soil product sits high in that hierarchy rather than heading for burial.

The 2020 sanitation framework law (Lei 14.026/2020) amended the solid-waste policy to set firm, staggered deadlines for every municipality to close its open dumps (lixões) and adopt environmentally adequate final disposal, with the final tranche — the smallest municipalities, those under 50,000 inhabitants — due by August 2024. Burial of untreated waste is being closed off nationwide, so an operator that keeps generating wet residue needs a treatment and recovery route such as drying.

Co-processing waste and biomass as alternative fuel and raw material in cement (clinker) kilns is a licensed recovery route in Brazil: it was established by CONAMA Resolution 264/1999 and updated by CONAMA Resolution 499/2020, which set the licensing criteria and atmospheric-emission limits for burning treated waste-derived and biomass fuels in place of fossil fuel. A dried, specification-consistent fuel is exactly what these kilns can accept.

With no separate Brazilian solid-recovered-fuel specification, producers and cement kilns characterise waste-derived and biomass fuels against the European ISO standards that local laboratories run — EN ISO 21640 for solid recovered fuel classification, the EN ISO 17225 series for solid biofuels, and EN ISO 18134 for moisture determination — so a dried fuel is traded on a documented calorific value and moisture grade.

Economic context
There is a large domestic market for a dried, specification-consistent alternative fuel. Brazil runs one of the world's biggest cement co-processing sectors: in 2024 alternative fuels — biomass, tyres and treated waste — reached about 30 per cent of the cement industry's thermal energy matrix, consuming roughly 3 million tonnes of waste and biomass and avoiding some 2,8 million tonnes of CO2 (ABCP/SNIC). That demand rewards a low, even moisture and a documented calorific value.

Bought-in power is a real cost: recent data put Brazil's weighted-average industrial electricity price at R$ 442,05/MWh, which favours drying systems built around recovered kiln, boiler or flue heat rather than grid electricity.

Worked illustration (assumptions stated):
SRF earns its keep by replacing coal in kilns that already draw about 30 per cent of their thermal energy from alternative fuels. That substitution avoids fossil fuel and the emissions with it – co-processing kept roughly 2,8 million tonnes of CO2 out of the air in a recent year – and operators report firm, growing demand for a reliable, spec-consistent fuel. Drying is the cost to manage: with industrial power at about R$ 442,05/MWh, running the FlowDrya on recovered process heat is what keeps SRF production profitable. A graded, dry fuel commands a stable price; a damp, off-spec one is rejected. Assumptions: grade, offtake and heat source vary by site.

SRF Dryer Manufacturer in Brazil — FAQ
Is there a FlowDrya SRF plant here?
Not yet. We will not claim a reference we do not hold; our FlowDrya lines dry SRF-type residues and biomass in Britain on the identical platform a producer here would receive.
What makes SRF different from RDF?
SRF is a more tightly specified fuel, classified against EN ISO 21640 on calorific value, chlorine and ash, with moisture a key property. Drying to a controlled, low moisture is what lets a producer certify and hold that class.
Why does a kiln pay more for dried SRF?
Because a consistent, low-moisture fuel substitutes more coal per tonne, burns stably and lets the operator plan around a documented grade – value a wet, variable fuel destroys.
Which authorisations does SRF co-processing need?
The cement sector's use of alternative fuel in clinker kilns is licensed under the CONAMA co-processing resolutions, and the waste treatment that makes the fuel is permitted under the national solid-waste framework.
How much fossil fuel can SRF displace?
Cement producers already draw about 30 per cent of their thermal energy from alternative fuels, and a dried, graded SRF is exactly the reliable input that makes that substitution worthwhile.
What contaminants matter in SRF?
Chlorine, ash and heavy metals are limited because they affect clinker chemistry and stack emissions; drying does not remove them, but a stable moisture lets a producer sample, certify and blend the fuel to stay inside the buyer's specification.
How is SRF quality documented?
Each batch is sampled and laboratory-tested for calorific value, chlorine, ash and mercury against the classification bands, then issued with a declaration a buyer can audit before delivery.
Why favour a domestic fuel over imported coal?
A locally produced SRF shields a kiln from swings in international coal prices and exchange rates, adding supply security to the cost and emissions benefits of substitution.
