Wood Chip Dryer Manufacturer in Sweden
See how we dry Wood ChipLooking for wood chip dryer 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.
Sweden is home to a documented FlowDrya woodchip line. At Kisebo Lantbruk AB, a family poultry farm, a FlowDrya built to order at STRONGA's Hertfordshire works dries FSC-certified pine woodchips using recovered heat from an on-site pyrolysis reactor, creating a stable, low-moisture feedstock for biochar; it is the reference listed above. Wood is the backbone of this energy system, carrying much of the country's district heat, and a boiler or a pyrolysis reactor runs cleanly only on chip of steady, low moisture. Freshly felled chip often reaches the yard near 65 per cent moisture, where much of the energy is wasted evaporating water and the fuel burns cool and smoky. Drying it toward 20 per cent, or to around 8 per cent for pellet feed, lifts net calorific value from about 6.5 MJ/kg toward 16 MJ/kg, steadies combustion and lets the chip be graded and sold on a documented specification.

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.

Sweden diverts almost all of its waste from landfill and recovers the energy through district heating. Less than 1 per cent of municipal waste is landfilled, and 34 waste-to-energy plants supply heat to about 1,445,000 households and electricity to about 780,000 households through the country's extensive district-heating networks. That infrastructure creates a deep, established market for a dry, high-calorific, consistent fuel and a clear economic penalty for shipping wet, low-grade material.

Worked illustration (assumptions stated):
The economics turn on calorific value, storage and cheap heat. A drier chip delivers more usable energy per tonne, so a district-heat plant burns fewer loads and a supplier ships less water; green chip left wet also composts in the pile, losing dry matter and heating value. Carbon policy pulls hard in the same direction: displacing fossil heat sidesteps a carbon tax that had reached SEK 1,200 per tonne of CO2, among the highest in the world, while installations inside the EU Emissions Trading System are exempt. The cement kiln at Slite on Gotland, which has replaced roughly 40 per cent of its coal with waste wood and other recovered fuels, shows the same appetite for a graded solid fuel. Because a chip line such as Kisebo runs on recovered reactor or boiler heat rather than grid power, the drying step barely touches electricity. Assumptions stated: moisture target, storage time and heat source govern payback.

Wood Chip Dryer Manufacturer in Sweden — FAQ
Do you have a Swedish wood chip installation?
Yes. Our Kisebo Lantbruk project dries FSC-certified pine woodchips on a FlowDrya line and is listed among the installations on this page. A reference discussion can be arranged subject to the customer's agreement.
Why does wood chip need drying?
Wet chip near 65 per cent moisture burns cool and smoky and rots in store, wasting energy on evaporating water. Drying it toward 20 per cent lifts net calorific value from about 6.5 MJ/kg toward 16 MJ/kg for clean, efficient combustion.
What does FlowDrya do at Kisebo?
It takes surplus heat from the farm's pyrolysis reactor and uses it to dry FSC-certified pine woodchips into a consistent, low-moisture feedstock for biochar, replacing a slower, more labour-intensive container-drying method.
What moisture do boilers and reactors need?
It depends on the plant. District-heat and chip boilers want a low, consistent moisture, while pellet presses and pyrolysis reactors need it lower still, toward 8 per cent. Each FlowDrya is configured to the target the process requires.
Can the dryer run on recovered heat?
Yes. A FlowDrya is commonly matched to recovered reactor, boiler or flue heat, so it needs very little grid electricity, which is what keeps the drying step economic on a woodchip line.
How does carbon policy help the business case?
Every tonne of fossil heat a dried chip displaces avoids a carbon tax that reached SEK 1,200 per tonne of CO2, one of the highest carbon prices in the world, so the saving is real and substantial.
