SRF Dryer Manufacturer in South Africa
See how we dry SRFLooking for SRF dryers manufacturers in South Africa? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to South Africa — see the regulatory and economic context below.
FlowDrya SRF dryers are engineered to order at STRONGA's Hertfordshire works and supplied to South African fuel producers, 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 decides 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 and sold on a documented specification. Producing and storing SRF is a listed waste activity requiring a licence under Act 59 of 2008.
Supplying South Africa
We supply South Africa from our Hertfordshire works — we have no documented SRF installation in South Africa yet.
Regulatory context
The National Environmental Management: Waste Act (Act 59 of 2008) is the framework statute for waste, built on the waste hierarchy; a listed waste management activity — including the treatment, recovery or processing of waste and the operation of a landfill — may not be undertaken without a waste management licence, so a drying-and-recovery operation is authorised through that licensing regime rather than tipped to landfill by default.

Organic residues are governed by the National Norms and Standards for the treatment of organic waste, published under the Waste Act in Government Notice 275 (Government Gazette 44340, 2021); the norms set treatment requirements for composting and anaerobic digestion and define the digestate that remains after a biodegradable feedstock is digested, the quality regime a dried fibre, manure or organic amendment answers to before it leaves site.

The Western Cape is phasing organic waste out of landfill, targeting a 50 per cent diversion of organics in 2022 and a full ban by 2027, enforced pragmatically through conditions written into each landfill's waste management licence — so an operator that keeps generating wet organic residue must find a treatment and recovery route, and drying is the step that makes that residue storable and marketable.

The National Waste Management Strategy 2020 sets the policy direction, applying the waste hierarchy and a circular-economy approach that prioritises recovery — including energy recovery from organic and other waste ahead of disposal — the national basis on which dried, waste-derived and biomass fuels are treated as resources rather than as material for burial.

In the absence of a bespoke national solid-fuel specification, producers and cement kilns characterise waste-derived and biomass fuels against the European ISO standards local laboratories use — 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 can be traded on a documented calorific value and moisture grade.

Economic context
Carbon carries a real and rising price: under the Carbon Tax Act (Act 15 of 2019) the rate rose to R308 per tonne of CO2 equivalent from 1 January 2026, the start of Phase 2, and is legislated to climb to R462 per tonne by 2030 — so every tonne of coal a dried, waste-derived or biomass fuel displaces avoids both the fuel bill and a growing carbon-tax liability.

Bought-in electricity is dear and getting dearer: NERSA approved a 12.74 per cent Eskom tariff increase for direct customers from 1 April 2025, on top of years of above-inflation rises and an unreliable grid — which favours drying systems built around recovered kiln, boiler or process heat rather than grid electricity.

There is a genuine domestic market for a dried, specification-consistent alternative fuel: the cement industry co-processes waste-derived fuel in its kilns and can reach a coal substitution rate of up to 30 per cent, and technical operators report that demand from cement producers for a reliable alternative fuel is real and growing as coal costs rise — demand that rewards a low, even moisture and a documented calorific value.

Worked illustration (assumptions stated):
SRF earns its keep by replacing coal in the cement kilns that can already substitute up to 30 per cent of their fuel. With the carbon tax at R308 per tonne of CO2 equivalent in 2026 and legislated to reach R462 by 2030, that substitution avoids a rising tax as well as the coal bill, and operators report firm, growing demand for a reliable, spec-consistent fuel. The drying step is the cost to manage: a 12.74 per cent electricity rise from 2025 makes grid power dear, so 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 South Africa — FAQ
Is there a FlowDrya SRF plant in the country?
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 that a wet, variable fuel destroys.
Which authorisations does SRF production need?
Treating and storing waste to produce solid recovered fuel is a listed activity requiring a waste management licence under Act 59 of 2008, and the receiving kiln must be authorised for co-processing.
How much coal can SRF displace?
Cement producers can substitute up to 30 per cent of their coal with alternative fuel, and a dried, graded SRF is exactly the reliable input that makes that substitution worth their kiln modifications.
What contaminants matter in SRF?
Chlorine, ash and heavy metals are limited because they affect a kiln's 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. Laboratories test each batch against the classification's mercury and calorific bands before dispatch, and kiln operators value the security of a domestic fuel that insulates them from imported-coal price swings and currency volatility.
