§ Mr. Michael Morrisasked the Secretary of State for Energy if he has investigated recycling waste lubricating oil and petrol contaminated paraffin back into the crude oil intake of United Kingdom oil refineries.
§ Mr. John SmithWaste lubricating oil is the main problem, and recycling of this material has been carried out in the United Kingdom for a number of years. In 1973 the quantity handled was about 18 million gallons. This oil is processed in special re-refining facilities rather than at conventional oil refineries.
