§ Mr. Simsasked the Secretary of State for the Environment what is the amount of time which must elapse before tips containing rubbish in non-biodegradable sacks can be used for building purposes; and what is the amount of time for those containing paper stocks.
§ Mr. MarksThis will vary according to the types of waste deposited and the disposal methods use but a long wait is usually necessary for the site to become sufficiently stable. The difference between non-biodegradable sacks and paper sacks is not likely to be significant; what is in them is more important. Sites can often be used for recreational and agricultural purposes very soon after completion.
