They separate the plastic and 'filling' part of the nappy.
The plastic bit gets made into small ball things and then is made into roofing materials etc.
As the 'filling' bit is in the form of gel (the gel that is in the nappy) they add some sort of chemical salt solution to it and this turns it back into water and fibre. They can then seaparate the two of these and reuse them.
Two things I wondered, is what the environmental cost of doing this is, i.e. does it require a lot of heat to do the process. And secondly, it still encourages people to recycle rather than reduce in the first place.
What does everyone else think?
