Sweden's program of producing energy from
rubbish is so successful, but recently its success has also produced a
surprising problem: There is simply not enough rubbish in this country. It has
been reported that only 4% of their rubbish goes into landfills. 96% is
recycled or recently being reused as fuel (燃料) in
their waste-to-energy factories that are able to deal with up to 2 million tons
of rubbish every year. And this situation has made Sweden face the serious and special
problem mentioned above.
Sweden has recently begun buying much waste
every year from other countries, such as Norway, Bulgaria, Romania and Italy. These
countries depend heavily on landfills. In the United States, where 250 million
tons of rubbish was produced in 2010 alone, only about 34% was recycled. As a
result, more than half of their waste ends up in landfills.
Sweden is now paid by Norway to take its
waste away. Sweden not only gets money from other countries but also changes
the waste into energy in Sweden, which provides electricity and heating for so
many homes. It's a win-win situation. Clever!
Sweden is leading the way in waste
management, but it is one of few. Most countries' technology in dealing with
waste needs improving. We live in a world that is full of rubbish like plastic
bags and beer bottles. Sweden's waste management offers a look into the future
where countries can make money from their rubbish and not just put it in the
ocean or put it in landfills.
