Even
as Indian cities like Bangalore slowly transform into one huge garbage
dump thanks to faulty civic planning, Sweden finds itself with a unique
problem on its hands: there’s no garbage left in the country. The
Scandinavian nation has been ‘importing’ trash from neighbouring Norway
to feed its waste-to-energy programme that provides,
through incineration, heat and electricity to thousands of households
in the country with a population of 9.5 million.
The story first broke on the American public radio organization Public Radio International and has since been picked up by a number of green blogs and websites. Sweden’s superefficient waste segregation and recycling systems have made sure only about 4% of the country’s waste ends up in landfills.
So
how did Sweden get so good at waste management, and what can other
countries learn from it? Firstly, Sweden started putting effective
systems in place from the early 1990s and took a holistic approach,
through policy changes, engagement with industry and awareness
programmes, to reach out to all stakeholders of Swedish society.
Producers were made responsible for dealing with several categories of
waste. Landfill bans and taxes were introduced, and targets set set for
increased recycling. More than 90% of household waste in Sweden is
recycled, reused or recovered.
By law, companies are responsible
for collecting the entire waste-stream stemming from their products,
either on their own or through public or private contractors, writes
Magnus Schönning in the Toronto Star. There is
a strong economic incentive for companies to produce less waste from
products and product packaging. Sweden has encouraged heavy recycling by
combining economic incentives, such
as garbage collection fees, with easy access to recycling stations and
public awareness campaigns, says the Toronto Star report. In 2005,
Sweden made it illegal to landfill organic waste. Instead, the waste is biologically treated to make compost, biogas and fertilizer.
However,
the bulk of the waste is converted into energy through processes that
have been refined over the years to be as clean and environmentally
sustainable as possible. In fact, Sweden claims that the damage to the
environment caused by the release of dioxins, harmful chemicals released
when waste is incinerated, is less than the damage caused by the
burning of fossil fuels.
Thanks to these proactive measures,
landfilling of household waste fell from 1,380,000 tonnes in 1994 to
380,000 tonnes in 2004. Around 1.3 million tonnes of materials and 5.7
TWh (terawatt hour) of energy in the form of heat and electricity were
recovered from household waste in 2004: an increase of 140% and 70%,
respectively, since 1994. Surely, Sweden is showing Asia's growing
cities how to make a clean sweep.
