I understand the hon. Gentleman's point. The waste acceptance criteria define inert waste. If biodegradable waste is treated so that it meets that definition, it ceases to be biodegradable waste, which answers the hon. Gentleman's point. Any plastic capable of anaerobic or aerobic composition is biodegradable waste, to which amendment No. 80 relates, and will be biodegradable waste according to the definition in the clause. I hope that the hon. Member for Guildford will be satisfied by that explanation and does not need to pursue the amendment.
On the main thrust of this group of amendments, however, I repeat that the matter is not about substantive policy issues but definitions, which I insist must be close, if not identical, to those in the landfill directive.
