Subject to paragraphs F3(2), (3) and (4), no establishment or undertaking which carries out the disposal or recovery of hazardous waste, or which produces, collects or transports hazardous waste, shall mix any hazardous waste.

Paragraph (1) does not apply to the extent that the mixing is part of a disposal or recovery operation and is authorised by, and is conducted in accordance with, the requirements (howsoever expressed) of a waste permit F4....

Paragraph (1) applies to the mixing of waste oil only where such mixing would impede regeneration or another recycling operation delivering an equivalent or a better overall outcome than regeneration.

In paragraph (4)—

• “recycling” means any recovery operation by which waste materials are reprocessed into products, materials or substances whether for the original or other purposes, including the reprocessing of organic material but not including energy recovery or reprocessing into materials that are to be used as fuels;

• “regeneration” means any recycling operation whereby base oils can be produced by refining waste oils, in particular by removing the contaminants, the oxidation products and the additives contained in such oils.

The holder must make arrangements for separation of the waste to be carried out in accordance with a waste permit or registered exemption as soon as reasonably practicable.

Where separation is not required pursuant to paragraph (2), the holder must make arrangements for mixed hazardous waste to be treated at a facility authorised by a waste permit to treat that waste.

In this Regulation “separation” means separation of a waste from any other waste, substance or material with which it has been mixed.
