Rubbish may be the only cargo in Europe where the sender pays the receiver and both parties walk away pleased.
Sweden brought in 2.92 million tonnes of notifiable waste in 2022, and by 2024 that had climbed to 3.86 million tonnes, according to cross-border transport figures from the Swedish Environmental Protection Agency. Britain, Norway and Italy supply most of it. Notifiable waste is a broad legal category covering household rubbish, construction debris, wood and hazardous material, so not every tonne of that ends up in a furnace, though plenty does.
None of it is being bought. Sweden charges for the favour.
A heating system that outgrew its country
District heating explains most of this. Instead of every building running its own boiler, one large plant heats water and sends it out through insulated pipes across an entire suburb, arriving eventually as warmth in a radiator in a Malmö flat, a few kilometres from wherever it started out. Sweden spent decades laying that pipework and then fed the plants with rubbish, because burning household waste throws off heat whether anyone planned for it or not.
Then the Swedes got annoyingly good at sorting.
Recycling climbed, landfill fell to almost nothing, and the furnaces were left with spare appetite. Capacity now runs ahead of what the country generates, as documented by the Nordic Council of Ministers in its review of incineration across the region. That same review puts the flow of imported fuel into dedicated incinerators at 1.4 to 1.6 million tonnes a year. It is a narrower measure than the headline import total, which also counts material bound for other treatment routes.
Nobody will tell you the current price
How much does a Swedish plant actually earn on a tonne of imported rubbish? The most solid public figure is over a decade old. In 2015 the public broadcaster SVT put the margin on imported waste at roughly 373 kronor a tonne, drawing on several industry sources to estimate the number for 2013. Heating plants took in 2.14 million tonnes between them that year, worth a shade over 798 million kronor.
Operators treat their current gate fees as commercially sensitive. Avfall Sverige, the industry’s trade association, confirmed as much when Snopes chased the question in late 2025: the rate is still a trade secret. Scale the old estimate against recent volumes and the sector clears a billion kronor a year, an extrapolation resting on a single reporter’s decade-old number.
Two payments for one delivery
A plant collects a fee for accepting foreign waste, burns it, then sells the resulting heat and power to Swedish households. Nationally, energy recovery produces heat for roughly 1,470,000 apartments and electricity for another 940,000, per the industry body Energiföretagen. Avfall Sverige puts the recovery rate at roughly 3 MWh a tonne, the best in Europe by the association’s own count.
Dependency is not the driver here. Avfall Sverige has long maintained that the plants could switch to biofuel if the foreign flow stopped, which frames importing as a commercial decision about spare capacity.
For a council in Manchester or Bergen the sums are dull and decisive. Once landfill tax, permits and the price of building your own facility are counted, loading the bales onto a ship bound for Sweden is simply cheaper. Europe still buries upwards of 100 million tonnes of rubbish each year, an estimate the operator of the Linköping plant gave to SVT while showing off a new furnace built largely for foreign feedstock.
What the critics keep saying
Swedish conservation group Naturskyddsföreningen has argued for years that a cheap disposal route abroad takes the pressure off exporting countries to build recycling capacity at home, and its magazine Sveriges Natur has raised concerns about dioxins and furans from an expanding incineration fleet. EU waste policy ranks recycling above energy recovery for related reasons. Burning a plastic tray recovers a few kilowatt hours of heat. Recycling it recovers the plastic.
Defenders of the trade point out that the alternative is usually a landfill somewhere in Europe leaking methane for the next thirty years, which is a low bar the furnaces clear comfortably.
Stockholm tried a tax and gave up
An incineration levy took effect in April 2020, reaching 125 kronor a tonne by the end of 2022, with the stated aim of pushing material up the waste hierarchy into recycling.
It lasted two and a half years.
Parliament scrapped it from 1 January 2023, as Skatteverket notified operators. A finance ministry memorandum released by the Swedish government set out the thinking: Russia’s invasion of Ukraine had upended the European electricity market, and heating companies had already begun revising their investment plans downward. Assessments of the levy found it had added cost and paperwork without shifting much material into recycling.
Which leaves the trade running, and quietly shifting underneath. Norway sends a large share of its residual waste across the border while steadily raising charges on its own incinerators, a tension flagged by the IEA Bioenergy group monitoring both countries. The councils currently paying to send their bin contents north are doing the sums on how much longer they want to keep doing it.
