The point that the hon. Member for Great Yarmouth (Mr. Wright) made was entirely reasonable, and I think that my hon. Friend is about to talk about volume, which is the key point. One problem that we have encountered throughout our proceedings is whether we measure waste by weight or by weight and volume. My hon. Friend the Member for Mid-Bedfordshire has constantly referred to that, and I draw the Committee's attention to his comments about the ratio of volume to weight of 2:1. I think that my hon. Friend the Member for South Holland and The Deepings (Mr. Hayes) will soon mention that.
