Digestate Dryer Manufacturer in Sweden
See how we dry Digestate FibreLooking for digestate dryers manufacturers in Sweden? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to Sweden — see the regulatory and economic context below.
FlowDrya digestate dryers are engineered to order at STRONGA's Hertfordshire works and shipped to biogas operators here, and we hold no commissioned digestate line on local soil to cite; our nearest documented project in the country dries woodchips for biochar. Digestate is plentiful because the ban on landfilling organic waste steers food waste, manure and sludge into anaerobic digestion rather than burial. To move that residue on as a saleable soil product it helps to meet the voluntary SPCR 120 biofertiliser (biogodsel) scheme run by RISE, which requires source-sorted feedstock, hygienisation and limits on heavy metals and visible contaminants. A wet fibre near 60 per cent moisture is heavy to cart and quick to degrade; drying it toward 15 per cent concentrates the nutrients, arrests the smell and helps the material hold a certified grade. Because separated fibre is corrosive, machines are supplied with a stainless-steel package.

Regulatory context
Swedish waste law rests on the Environmental Code (miljobalken) and the Waste Ordinance (avfallsforordning 2020:614) issued under it. Chapter 15 of the Code sets the waste hierarchy, giving reuse, recycling and other recovery priority over disposal, and the ordinance operationalises it: separately collected material intended for recovery may not simply be incinerated, and municipalities must reach material-recovery rates of 55 per cent by 2025, 60 per cent by 2030 and 65 per cent by 2035. Turning a wet residue into a fuel or a stabilised soil product is a recovery route the law ranks above burial.

Sweden bans the landfilling of waste that a dryer helps divert. Under the Ordinance on the Landfill of Waste (forordning 2001:512 om deponering av avfall), section 8 prohibits depositing sorted combustible waste, a ban in force since 2002, and organic waste, banned since 2005. Exemptions are narrow and granted case by case by the county board or the Environmental Protection Agency. Because burial is closed to these fractions, the residual and organic streams must instead be recovered as fuel or soil products, which is the single strongest legal driver for drying wet residues in this market.

The incineration and co-incineration of waste is governed by the Ordinance on the Incineration of Waste (forordning 2013:253 om forbranning av avfall), which implements the EU Industrial Emissions Directive. It covers dedicated energy-from-waste plants and co-incineration installations alike, and sections 67 to 70 set specific emission limits and permit conditions for cement kilns burning waste-derived fuel. A cement kiln or power plant firing refuse- or solid-recovered fuel operates under this ordinance, and a dried, consistent, low-moisture fuel is what keeps such a plant reliably inside those limits.

Digestate and compost sold as soil products are quality-assured through the voluntary SPCR 120 (biogodsel) and SPCR 152 (compost) certification schemes run by RISE, the Research Institutes of Sweden, as an independent certifier. The rules require that the product is made from clean, source-sorted, biologically degradable substrates from the food or feed chain, that it is hygienised, and that it meets limits on heavy-metal content and visible contaminants, verified through a qualification year and external audits. A dried, stabilised material holds those limits far more readily than a wet, actively degrading feedstock.

Economic context
Sweden runs one of the world's highest carbon prices. The carbon tax (koldioxidskatt) was introduced in 1991 at SEK 250 per tonne of carbon dioxide and had risen to SEK 1,200 per tonne by 2021, applied to fossil fuels used outside the EU Emissions Trading System; installations already covered by the EU ETS are exempt from the domestic tax to avoid double charging. Every tonne of fossil fuel a dried waste- or biomass-derived fuel displaces therefore avoids a real and steep carbon cost.

The Swedish carbon tax is among the highest in the world. In 2026 it stood at 133.17 euros per tonne of CO2, second only to Norway, giving Swedish industry one of the strongest financial incentives in Europe to substitute coal, coke or oil with a recovered fuel or to raise process heat from biomass rather than fossil sources.

Worked illustration (assumptions stated):
The case rests on haulage, offtake value and cheap heat. Water is dead weight, so pulling a fibre from around 60 per cent moisture toward 15 per cent slashes the tonnage a tanker carries and lets the dried product travel to arable farms that will pay for it. A biogas plant already makes its own low-grade heat, and firing the dryer on that recovered engine or exhaust heat rather than grid power keeps conversion cheap. Carbon policy sharpens the incentive to run on renewable heat: the carbon tax reached SEK 1,200 per tonne of CO2, among the highest in the world, though EU Emissions Trading System installations are exempt. A certified, dried biofertiliser earns a firm price where a wet, degrading slurry cannot travel or be spread evenly. Assumptions stated: nutrient value, transport distance and available waste heat govern payback.

Digestate Dryer Manufacturer in Sweden — FAQ
Do you supply digestate dryers here?
Yes, from our Hertfordshire factory. We hold no commissioned digestate line on local soil yet and will not imply one; our documented Swedish project dries woodchips for biochar on the same continuous-flow FlowDrya platform a digestate line would use.
How does SPCR 120 shape digestate drying?
The voluntary SPCR 120 scheme certifies biofertiliser made from clean, source-sorted feedstock that is hygienised and within heavy-metal and contaminant limits. A dried, stabilised fibre holds those requirements far more reliably than a wet, actively degrading feedstock.
Why dry digestate at all?
Water is the enemy of haulage and shelf life. A fibre near 60 per cent moisture is costly to move and quick to rot; drying it toward 15 per cent concentrates nutrients, stops biological activity and yields a stable product a farm will buy.
Does drying help meet the landfill rules?
Yes. Organic waste has been barred from landfill since 2005, so digestate must be recovered as a soil product or a fuel. Drying turns it into a marketable, storable material rather than a disposal problem.
Can the dryer run on biogas heat?
Yes. A FlowDrya is commonly matched to the recovered engine, exhaust or CHP heat a biogas plant already produces, so it needs very little grid electricity to run.
How is a 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 supervised start-up and trial before handover, with operator training included.
