The Minister is asking what we do when waste has been biodegraded by some other method. In the case of the feathers, which I described earlier, it is soil, which is then put on a field. It could be put in a hole in the ground, which might be construed as landfill. That is why the definition is important, because the sort of landfill that soil and feathers represent is not the sort of landfill that we are talking about in the Bill. However, the example is still valid, which is why the definitions are critical.
