I was clearly doing so with insufficient clarity, but that was the point that I was trying to make. However, the hon. Member for Great Yarmouth may have something, in that the calculation will not be simple. There will be occasions when the larger package may be more desirable than the smaller, or the heavier package
more desirable than the lighter. That, I think, was the argument put by the hon. Member for Great Yarmouth.
We need to measure the likely reuse or recycling of material, or whether it is possible to recover it. That is not as simple as it may appear, but given that we cannot analyse every piece of waste in fine detail at every point of collection and disposal, the volume to weight ratio would at least give us a handle on the increased amount of waste that is large and bulky but not heavy.
I am interested in what the hon. Member for Great Yarmouth said. I shall certainly give it proper consideration, and I am sure that the Minister will do likewise. Neither the hon. Gentleman nor I would qualify on either volume or weight, and the ratio would do neither of us much good. None the less, we should probably have it. I shall conclude by saying that the three-way change of culture that I identified is pertinent and necessary; and that would be assisted by what is yet another constructive amendment.
