Sweden produces about 4.4 million tons of waste a year，but only 1%makes its way to the landfill.When it comes to waste management，Sweden is ahead of its time.How has Sweden done it？
   In Sweden，everyone works hard to make the environment free of waste.People are taught to recycle from a very young age.They are asked to return cans and bottles to supermarkets.The government places recycling stations no more than 300 meters from homes，schools，and offices. These all help waste management in Sweden much easier and more practical.
   The country also rewards those who recycle.In 1984，Sweden started the panta system.It encourages people to recycle bottles in exchange for money.The process is very simple.People put their items into a machine.Each piece has a small barcode that tells the machine how much it is worth.People can collect a voucher for that amount by pressing a green button，or they can donate the money to charity by pressing a yellow button.In 2021，the Swedish recycled 1.8 billion bottles and cans by using panta system.
   Sweden recycles nearly 50%of what it throws away.But what about the other half？_______ Altogether Sweden has 34 waste- to- energy plants that provide 1，445，000 homes with heat and 780，000 homes with electricity.Changing waste into energy has reduced Sweden's CO₂ emissions by 2.2 million tons a year.In 2016，Sweden had started running out of trash，so it began importing waste from other countries.It not only keeps the plants working，but also lets Sweden make much money.That is what makes Sweden different from the other countries.
   Sweden's waste management has made a great success.But still，the country is wondering how it can do more.They hope to see a day when landfills are a thing of the past.
