There are downsides to the argument about waste as measured by weight and volume. A paper pulp manufacturer in my constituency manufactures egg cartons, which are considerably heavier than the new plastic cartons. One could probably get 10 plastic egg cartons to one paper pulp egg carton. The proposals would give an unfair advantage to the plastic industry, even though paper is biodegradable and breaks down. The hon. Gentleman's argument would therefore prevent the company in my constituency from being competitive in the market and would probably work against other paper pulp manufacturers.
