"Recovery means any operation the principal result of which is waste serving a useful purpose
by replacing other materials which would otherwise have been used to fulfil a particular function,
or waste being prepared to fulfil that function, in the plant or in the wider economy".

"Recycling means any recovery operation through which waste materials are reprocessed into products,
materials or substances whether for the original or other purposes. It includes the reprocessing of organic material
but does not include energy recovery and the reprocessing into materials that are to be used as fuels or for backfilling
operations".
