</figure>It is a stricter regime than the transfer note because the consequences of mishandling are greater. The note travels with the load, and each party completes their part of it at the point they take the waste on.
The receiving site returns information about what it did with the consignment, which closes the loop. That return is what tells a producer their waste reached a lawfully permitted destination rather than simply left the site.
Requirements differ between the UK nations, including on registration and notification. An operator working across a border cannot assume one set of procedures covers both.
What goes wrong in practice
- Hazardous waste moved on an ordinary transfer note because it was not recognised as hazardous.
- Consignee returns never checked, so the chain is unverified at exactly the point that matters.
- Notes completed at the depot rather than at the point of collection, breaking the chain of custody.
- Cross-border movements handled under one nation's procedure throughout.
