Going, going, gone
Micro-organisms in the soil get to work on the plastics straight away. Within two weeks the seed has started to sprout and the plastic should all be gone within a month.
'The great thing about this plastic is that it doesn't biodegrade in a normal working environment - it has to have very special conditions to start the process,' explains Kerry. 'This means that you can use it in everyday life but the minute you pop it in the ground it begins to break down.'
