I can give my hon. Friend the assurance he is seeking. I will look at the classification system for inactive waste—particularly the position of fly-ash. We have considered that before, but I am happy to take a fresh look at it.

I am not sure that I can be quite so positive in response to the hon. Member for Falmouth and Camborne. I am unconvinced about the need for a new waste tax, and, in the end, tax is not the only type of policy that needs to play a part in dealing with how we manage and dispose of waste and increase waste recycling. The Government have a number of measures in place and perhaps need to consider other future measures. She may be interested to know that the Secretary of State for Environment, Food and Rural Affairs will shortly publish a renewed waste strategy that pulls together much of the work that we have done across Government on how to raise our game for the future.
