“I’d like to take some from the United States,” said Pal Mikkelsen, in his office at a huge plant on the edge of town that turns garbage into heat and electricity. “Sea transport is cheap.”
Oslo, a recycling-friendly place where roughly half the city and most of its schools are heated by burning garbage — household trash, industrial waste, even toxic and dangerous waste from hospitals and drug arrests — has a problem: it has literally run out of garbage to burn.
The problem is not unique to Oslo, a city of 1.4 million people. Across Northern Europe, where the practice of burning garbage to generate heat and electricity has exploded in recent decades, demand for trash far outstrips supply. “Northern Europe has a huge generating capacity,” said Mr. Mikkelsen, 50, a mechanical engineer who for the last year has been the managing director of Oslo’s waste-to-energy agency.
Yet the fastidious population of Northern Europe produces only about 150 million tons of waste a year, he said, far too little to supply incinerating plants that can handle more than 700 million tons. “And the Swedes continue to build” more plants, he said, a look of exasperation on his face, “as do Austria and Germany.”
Stockholm, to the east, has become such a competitor that it has even managed to persuade some Norwegian municipalities to deliver their waste there. By ship and by truck, countless tons of garbage make their way from regions that have an excess to others that have the capacity to burn it and produce energy.
“There’s a European waste market — it’s a commodity,” said Hege Rooth Olbergsveen, the senior adviser to Oslo’s waste recovery program. “It’s a growing market.”
Most people approve of the idea. “Yes, absolutely,” said Terje Worren, 36, a software consultant, who admitted to heating his house with oil and his water with electricity. “It utilizes waste in a good away.”
The English like it, too, though they are not big players in the garbage-for-energy industry. The Yorkshire-based company that handles garbage collection for cities like Leeds, in the north of England, now ships as much as 1,000 tons a month of garbage — or, since the bad stuff has been sorted out, “refuse-derived fuel” — to countries in Northern Europe, including Norway, according to Donna Cox, a Leeds city spokeswoman.
A British tax on landfill makes it cheaper to send it to places like Oslo. “It helps us in reducing the escalating costs of the landfill tax,” Ms. Cox wrote in an e-mail.
For some, it might seem bizarre that Oslo would resort to importing garbage to produce energy. Norway ranks among the world’s 10 largest exporters of oil and gas, and has abundant coal reserves and a network of more than 1,100 hydroelectric plants in its water-rich mountains. Yet Mr. Mikkelsen said garbage burning was “a game of renewable energy, to reduce the use of fossil fuels.”
Of course, other areas of Europe are producing abundant amounts of garbage, including southern Italy, where cities like Naples paid towns in Germany and the Netherlands to accept garbage, helping to defuse a Neapolitan garbage crisis. Yet though Oslo considered the Italian garbage, it preferred to stick with what it said was the cleaner and safer English waste. “It’s a sensitive question,” Mr. Mikkelsen said.
Garbage may be, well, garbage in some parts of the world, but in Oslo it is very high-tech. Households separate their garbage, putting food waste in green plastic bags, plastics in blue bags and glass elsewhere. The bags are handed out free at groceries and other stores.
