Digestate Dryer Manufacturer in Brazil
See how we dry Digestate FibreLooking for digestate 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.
We build FlowDrya digestate fibre dryers to order at STRONGA's Hertfordshire works and ship them to anaerobic-digestion operators here, though no FlowDrya digestate line has been commissioned in the country yet. Drying matters because separated digestate destined for farmland behaves like a biosolid: under CONAMA Resolution 498/2020 the material is graded by pathogen reduction into Class A and Class B, and thermal drying is one of the recognised processes that reaches the stricter, less-restricted Class A grade. Pulling wet fibre down to a low, even moisture concentrates its nitrogen and phosphate and protects it in storage. Because separated digestate runs acidic and ammonia-rich, every machine we send carries a stainless-steel package.

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.

Treated organic residues placed on land are governed by CONAMA Resolution 498/2020, which sets the criteria for producing and applying biossólido (treated sewage sludge and comparable biosolids) to soils. It grades the material by pathogen reduction into Class A and Class B and lists thermal drying among the processes that achieve the stricter Class A standard, so drying is not only a handling step but a recognised route to the higher-value, less-restricted grade.

Economic context
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.

Renewable fuels earn a genuine incentive. Under RenovaBio (Lei 13.576/2017), the national biofuels policy administered by the ANP, certified producers — including biomethane producers upgrading biogas — issue tradable decarbonisation credits (CBIOs), a real revenue stream that helps fund the digestion and drying equipment a site still needs.

Worked illustration (assumptions stated):
An anaerobic-digestion site earns from gas and heat first, but the fibre is where drying pays. Under RenovaBio (Lei 13.576/2017), a producer upgrading biogas to biomethane can issue tradable decarbonisation credits, so many plants are cash-generative before the digestate is handled. Drying then turns a tankering-and-storage liability into a saleable Class A soil product, animal bedding or solid fuel. Running the dryer on the plant's own combined-heat surplus rather than buying grid power at R$ 442,05/MWh keeps operating cost low, and a dry, friable fibre carts economically to growers instead of being hauled wet. Assumptions: credit eligibility, heat source and offtake values vary site by site.

Digestate Dryer Manufacturer in Brazil — FAQ
Do you have a digestate drying installation here?
Not yet. We will not imply a reference we do not hold; our documented FlowDrya lines dry digestate fibre, bark and woodchip in Britain on the identical platform an operator here would receive.
How does drying protect the fibre's status as a soil product?
Land application depends on meeting the CONAMA 498/2020 biosolids criteria. Drying to a stable low moisture supports the Class A pathogen standard and concentrates the nutrients, keeping the product within a specification a grower relies on.
Which rule governs digestate reuse in the country?
Treated sewage-type sludge and comparable biosolids placed on soil are graded under CONAMA Resolution 498/2020 into Class A and Class B; a dried, documented product is far easier to place compliantly.
How does RenovaBio improve the economics?
Upgrading biogas to biomethane can earn tradable decarbonisation credits under RenovaBio, adding a revenue stream that helps fund the separation and drying equipment a site still needs.
What end markets take the dried fibre?
Depending on grade, arable and horticultural growers wanting a phosphate-rich amendment, livestock yards seeking absorbent bedding, and pellet mills producing a compact renewable fuel. Dry, friable fibre blends predictably and freights well.
Does the stainless build suit corrosive digestate long term?
Yes. The stainless enclosure resists the acidic, ammonia-laden vapour that shortens the life of mild-steel dryers, giving digestion operators a durable asset over decades of service.
