Environment Waikato have done some research on the length of time it takes for different types of rubbish to break down in water. Since there are occasions when we are all tempted to drop something overboard, these results serve as a useful reminder to dispose of our rubbish more appropriately:
Cardboard box – two months
Apple core â two months
Tin and aluminium cans â 50 years
Plastic bottle â 450 years
Disposable nappies â 450 years
Fishing line â 600 years
