Running Out of Garbage? Want to ship some more to Norway?

OSLO, Capital of Norway, is a city that imports garbage. Some comes from England, Ireland and from neighboring Sweden. It even has designs on the American market.

A trash incinerator. Roughly half of Oslo and most of its schools are heated by burning garbage.

“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.

The larger of Mr. Mikkelsen’s two waste-to-energy plants uses computerized sensors to separate the color-coded garbage bags that race across conveyor belts and into incinerators.

The building’s curved exterior, with lighting that is visible from a long distance to motorists driving by, competes architecturally with Oslo’s striking new opera house.

Still, not everybody is comfortable with this garbage addiction. “From an environmental point of view, it’s a huge problem,” said Lars Haltbrekken, the chairman of Norway’s oldest environmental group, an affiliate of the Friends of the Earth. “There is pressure to produce more and more waste, as long as there is this overcapacity.”

In a hierarchy of environmental goals, Mr. Haltbrekken said, producing less garbage should take first place, while generating energy from garbage should be at the bottom. “The problem is that our lowest priority conflicts with our highest one,” he said.

“So now we import waste from Leeds and other places, and we also had discussions with Naples,” he added. “We said, ‘O.K., so we’re helping the Neapolitans,’ but that’s not a long-term strategy.”

Maybe not, city planners say, but for now it is a necessity. “Recycling and energy recovery have to go hand in hand,” said Ms. Rooth Olbergsveen, of the city’s waste recovery agency. Recycling has made strides, she said, and the separation of organic garbage, like food waste, has begun enabling Oslo to produce biogas, which is now powering some buses in downtown Oslo.

Mr. Haltbrekken acknowledged that he does not benefit from garbage-generated energy. His home near the center of town, built about 1890, is heated by burning wood pellets, and his water is heated electrically. In general, he said, Friends of the Earth supports the city’s environmental goals.

Yet he added, “In the short-term, it’s better to burn the garbage in Oslo than to leave it in Leeds or Bristol.”

But “in the long term,” he said, “no.”

A version of this article appeared in print on April 30, 2013, on page A9 of the New York edition with the headline: A City That Turns Garbage Into Energy Copes With a Shortage.

Sweden Out of Garbage

Imagine a world where pollution is a non-issue, cities are pristine, healthy environments to live in, and little to no entanglements from discarded trash injures wildlife or clogs the oceans.

In Sweden, this is almost a reality, yet it’s causing a paradoxical predicament for the recycle-happy country that relies on waste to heat and provide electricity to hundreds of thousands of homes.

Sweden Runs Out of Garbage

Trash piled 9 yards high is converted to heat and electricity at a waste-to-energy incinerator in Oslo.

The Scandinavian nation of more than 9.5 million citizens has run out of garbage; while this is a positive – almost enviable – predicament for a country to be facing, Sweden now has to search for rubbish outside of its borders to generate its waste-to-energy incineration program.

It’s namely Norway officials who are now shipping in 80,000 tons of refuse annually to fuel the country with outside waste.

The population’s remarkable pertinacious recycling habits are inspiration for other garbage-bloated countries where the idea of empty landfills is scarce. In fact, only 4% of all waste in Sweden is land-filled, a big win for the future of sustainable living.

By using its 2 million tons of waste as energy and scrapping for more outside of its borders, this country is shown in international comparisons to be the global leader in recovering energy in waste. Go Sweden.

Public Radio International has the whole story.

This (albeit short-term) solution is even highly beneficial for the Scandinavian country; Norway pays Sweden to take its excess waste, Sweden burns it for heat and electricity, and the ashes remaining from the incineration process, filled with highly polluting dioxins, are returned back to Norway and land filled.

Catarina Ostland, senior advisor for the Swedish Environmental Protection Agency, suggests that Norway may not be the perfect partner for the trash import-export scheme, however. “I hope that instead we will get the waste from Italy or from Romania or Bulgaria, or the Baltic countries because they landfill a lot in these countries” she tells PRI. “They don’t have any incineration plants or recycling plants, so they need to find a solution for their waste”.

There’s definitely something to be said about being ‘green’. Regardless of its sourcing, hopefully Sweden’s impeccable job of reducing its carbon footprint may serve as an example to other areas of the world that have more than enough trash to utilize and put to sustainable use.

Flower Pots and Tea Lights used to heat your home?

Wanting to cut costs on the energy bill, especially now that temperatures are dropping for the season?

Economics may be one reason to seek more sustainable energy sources, but this inventive way to heat the house is also purely fascinating.

How to Easily Heat Your Home Using Flower Pots & Tea Lights

Journalist, YouTuber, and boat owner Dylan Winter created his DIY heater using tea lights and placed inside a bread tin and covered with two ceramic flowerpots.

By: Amanda Froelich,

This creative system uses the scientific principles of convection heat transfer to heat his home for around 8 hours a day.

His YouTube Channel KeepTurningLeft shows how the method works: The tea lights are first put into a bread loaf tin and covered with a small upside-down flower pot.

The hole in the top of the upside-down pot is covered with the metal casing leftover from one of the tea lights. The pot is covered by a second, larger pot and the hole in the bigger flower pot is left uncovered.

This system works because the candles produce gases full of heated particles that are captured and channeled through the pots. As hot gas particles are lighter than the air, they will rise up through the top into the colder area.

The cold air is caused to fall into the warm areas and create a convection current; then heat is transferred from one pot to another, and then out of the hole.

One does not need a huge amount of money to invest in this economical heating method, either. Winter began by buying 100 tea lights from Ikea for less than a dollar, a standard loaf tin, and two different sized flower pots. In the video it is shown four candles are used for the heating system.

Sharing his invention with the world, Dylan explains that the heat from the candles warms the inside of the smaller flower pot, which becomes an ‘inner core’ that gets ‘very hot’. As explained before, a convection of air is then created between the smaller and larger pots and this heated air comes out of the top of the homemade heater.

When asked about his heater, he said: “People have told me that judicious positioning of flowerpots help to make the heating more efficient. I did not believe it but it really does seem to work.

You get a nice flow around the [pots] and it warms the room up. You’d be amazed.”

Dylan even uses the flowerpot method on his boats to conduct heat.

Truly inspiring for those seeking to simplify, be more frugal with their dollar, and leave less waste, perhaps this system will warm many families this year as winter makes itself more present.
