HL Deb 20 December 2001 vol 630 c89WA
Baroness Howe of Idlicote

asked Her Majesty's Government:

Whether, as processed incinerator bottom ash is used as an aggregate substitute for road base, they have now concluded that this process can be classified as "recycling" in the same way as he similar use of crushed glass cullet (CGC) is so classified. [HL1931]

Lord Whitty

The Government consider waste to be recycled if it has been subjected to a recycling process, ie, has been reprocessed in a production process for the original purpose or for other purposes. When the incinerator bottom ash has gone through such a process, the Government would consider that the ash has been recycled.
