Sweden Runs Out Of Garbage

Sweden Runs Out Of Garbage, Forced to Import From Norway

By: Amanda Froelich,
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.
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 percent of all waste in Sweden is land-filled, a big win for the future of sustainable living. By using its two 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.

American Teen Designs Compact Reactor

Eighteen-year-old Taylor Wilson has designed a compact nuclear reactor that could one day burn waste from old atomic weapons to power anything from homes and factories to space colonies.

The American teen, who gained fame four years ago after designing a fusion reactor he planned to build in the garage of his family’s home, shared his latest endeavor at a TED Conference in southern California on Thursday.

“It’s about bringing something old, fission, into the 21st Century,” Wilson said. “I think this has huge potential to change the world.”

He has designed a small reactor capable of generating 50-100 megawatts of electricity, enough to power as many as 100,000 homes.

The reactor can be made assembly-line style and powered by molten radioactive material from nuclear weapons, Wilson said. The relatively small, modular reactor can be shipped sealed with enough fuel to last for 30 years.

“You can plop them down anywhere in the world and they work, buried under the ground for security reasons,” he said, while detailing his design at TED.

“In the Cold War we built up this huge arsenal of nuclear weapons and we don’t need them anymore,” Wilson said. “It would be great if we could eat them up, and this reactor loves this stuff.”

His reactors are designed to spin turbines using gas instead of steam, meaning they operate at temperatures lower than those of typical nuclear reactors and don’t spew anything if there is a breach.

The fuel is in the form of molten salt, and the reactors don’t need to be pressurized, according to the teenager.

“In the event of an accident, you can just drain the core into a tank under the reactor with neutron absorbers and the reaction stops,” Wilson said.

“There is no inclination for the fission products to leave this reactor,” he said. “In an accident, the reactor may be toast, which is sorry for the power company, but there is no problem.”

Wilson, who graduated grade school in May, said he is putting off university to focus on a company he created to make Modular Fission Reactors.

He sees his competition as nations, particularly China, and the roadblocks ahead as political instead of technical.

Wilson planned to have a prototype ready in two years and a product to market in five years.

“Not only does it combat climate change, it can bring power to the developing world,” Wilson said with teenage optimism.

“Imagine having a compact reactor in a rocket designed by those planning to habitat other planets. Not only would you have power for propulsion, but power once you get there.”
