Chain-of-Custody (Digital)
In-depth regulatory definition and operational context for Chain-of-Custody (Digital) under 2026 mandates.
Digital Chain-of-Custody is the immutable electronic audit trail of every person or business that has handled a specific load of waste. It is formed by the digital links between the producer, carrier, and receiver.
Technical Guidance & Context
Under DWT, each party must acknowledge their role in the movement. This makes it significantly harder for waste to be "lost" or diverted to illegal sites, as the digital record remains "open" until the final destination site confirms receipt.

UMR
A Unique Movement Reference (UMR) is a digital 'passport' for waste shipments in the UK. It must be generated before waste leaves a producer's site and closed by the receiver within 48 hours.
Record-Before-Move
Record-Before-Move is a core regulatory principle requiring a digital waste record to be created on the national service before waste physically leaves a site. This ensures that every shipment on the road is already accounted for in the digital system.
Waste Receiving Site (Phase 1)
Waste Receiving Sites are the first group of operators mandated to use the Digital Waste Tracking service, beginning in October 2026. This includes any facility permitted to accept, treat, or dispose of waste.
