Pharmaceutical manufacturing sites are normally very secure, as required by the regulatory requirements for licensing of the manufactured produst(s). However, security of waste outputs may not be so good, and as these drug wastes are removed for high temperature incineration, security is at best lax and in some cases almost non-existent. Traceability is poor, despite an obligation in pharmaceutical manufacturing and waste-related legislation.
