To ask the Secretary of State for Environment, Food and Rural Affairs what estimate he has made of the number of (a) mobile telephones and (b) printer cartridges which were (i) recycled, (ii) reused overseas and (iii) disposed of within the waste stream in each year since 1997; what research his Department has (A) commissioned and (B) evaluated on the disposal of mobile telephones and printer cartridges in that period; and if he will make a statement. (286468)

Information on the number of mobile phones and printer cartridges recycled, reused or disposed of is not collected centrally. The Department has not commissioned research into the disposal of these items. We have, however, published guidance on the treatment of waste electrical and electronic equipment which includes mobile phones and printers, which is available on DEFRA's website.
