Because it has become so good at recycling, Sweden now is importing 800,000 tons of trash each year from other European countries, including Norway, to power its waste-to-energy program, Public Radio International reports. Burned waste powers 20 percent of Sweden's district heating as well as electricity for roughly 250,000 Swedish homes.Swedish households recycle most of their waste; only 4 percent of it ends up in landfills, according to PRI.
