It is good practice to record waste disposal and ensure you have full traceability and can account for all your finished products.
This something BRC in particular are a bit sharper on as products have been known to have been 'intercepted' on route to disposal and sold on:
'4.12.3 If unsafe products or substandard trademarked materials are transferred to a third party for destruction or disposal, that third party shall be a specialist in secure product or waste disposal and shall provide records which include the quantity of waste collected for destruction or disposal.'
SQF 11.9.1 Implementation Guidance
The procedures for storage and disposal of all types of waste – dry and liquid – must be documented and implemented. The procedure will include how waste is contained in appropriate, covered and labeled containers; the frequency of disposal; how it is disposed of; and who is responsible for it. Local regulations and community expectations concerning recycling and waste disposal and transport must also be considered.
11.9.1 Auditing Guidance
