How Long Does Rubbish Take To Decompose?

Today we spent time with our buddy class to work out how long various pieces of rubbish take  to decompose.  We were amazed how long many things took. Some never break down! Styrofoam, plastic and glass bottles are estimated to take 1 million years or never. Even aluminum cans take 200 to 500 years. Scary!


  1. I learnt a lot while doing it.I won't put rubbish in my lunch from now on.Why does it take so long?


  2. Isn't it scary Knowing that plastic never breaks down i wonder how long cooking foil takes to break down

  3. HI,
    I learnt a lot while we did this. WHY DID IT HAVE TO BE SO HARD! How many questions where there?

  4. Oh my gosh, all those things take so long to decompose. They must be really stubborn. Are there any others that take more than a million years?
