To ask the Secretary of State for the Environment, pursuant to his answer to the hon. Member for Devizes (Sir C. Morrison) of 23 April, Official Report, column 2, if he will give further details of the research being carried out into toxic and problem waste management and chemical, thermal and biological detoxification.

The following two broad headings which were used in my previous answer include the listed detailed objectives:

Toxic and Problem Waste Management
  • To determine a variety of ways in which asbestos waste of various types may be reliably and economically destroyed.
  • To determine operational quality control procedures for the assessment of cement-based solidified wastes under field conditions.
  • To determine the extent of any potential hazard arising from disposing of mercury containing batteries with household waste.
Waste Management
  • To determine the general operating conditions under which PCBs can be destroyed by high temperature hydrogen reduction.
  • To determine whether waste acids or other suitable chemicals may be utilised to degrade persistent pesticide wastes.
