24.—(1) Where a person other than a district council, for the purpose of recycling it, collects waste arising in the district of a district council which would fall to be collected under Article 20, the council may make to that person payments, in respect of the waste so collected, of such amounts representing its net saving of expenditure on the collection and disposal of the waste as the council determines.
(2) Regulations may require district councils to make payments corresponding to the payments which are authorised by paragraph (1) to such persons in such circumstances and in respect of such descriptions or quantities of waste as are specified in the regulations.
(3) For the purposes of paragraph (1)—
(a)the net saving of expenditure of a district council on the disposal of any waste collected for recycling is the amount of the expenditure which the council would, but for the collection, have incurred in having it disposed of less any amount payable by the council to any person in consequence of the collection for recycling (instead of the disposal) of the waste; and
(b)the net saving of expenditure of a district council on the collection of any waste not falling to be collected by it is the amount of the expenditure which the council would, if it had had to collect the waste, have incurred in collecting it.
(4) Regulations shall make provision for the determination of the net saving of expenditure for the purposes of paragraphs (1) and (2).
