Digital compliance for hazardous waste carriers

Hazardous waste is a different job from ordinary waste — and a different paper trail. A carrier moving waste oils, solvents or asbestos isn't filling in a standard transfer note at all; they need a hazardous waste consignment note, with a consignment code, HP codes and a longer retention period. Here is what those extra duties are, and how digital software keeps them right at the roadside.

Do hazardous waste carriers use a waste transfer note or a consignment note?

The distinction matters because the two documents aren't interchangeable. If you carry hazardous waste on an ordinary transfer note, you don't have a compliant record — you're missing the consignment code, the HP codes and the register entry the law expects. Everything about the hazardous workflow — the fields, the retention, the registration tier — steps up.

Which wastes are hazardous, and what are the EWC codes?

Hazardous waste is any waste with a hazardous property. In the European Waste Catalogue (EWC), hazardous entries are marked with an asterisk — if a code ends in *, the waste is hazardous and needs a consignment note. These are the streams hazardous carriers meet most often:

Picking the wrong code — or missing the asterisk — is the classic hazardous error. It changes whether the movement needs a consignment note at all, so getting the EWC selection right is the foundation of the whole record.

What extra requirements do hazardous consignment notes have?

A consignment note is a transfer note plus several things a standard WTN never asks for. Miss any of them and the record isn't compliant:

• →Consignment note code. A unique reference identifying the single movement, linking producer, carrier and receiver to one consignment.
• →HP (hazardous property) codes. Codes from HP1 to HP15 describing the danger — flammable, corrosive, toxic, infectious — so everyone handling the waste knows what they're dealing with.
• →Asterisked EWC code. The hazardous entry from the European Waste Catalogue that classifies the waste.
• →A consignment register. You must keep a register of consignment notes — and hold it, with the notes themselves, for at least 3 years.

Are hazardous waste carriers upper-tier or lower-tier?

This is a common trap for firms that started out moving only their own or general waste under a lower-tier registration and then took on a hazardous job. The moment hazardous waste is on the vehicle, upper-tier registration applies. It's worth confirming your tier before you book the first hazardous collection.

Why is capturing a hazardous note harder on paper?

Every problem with paper transfer notes is worse for hazardous waste, because there's simply more to get right, and it's being written down in a cab or on a verge:

• →More fields. A consignment note has everything a WTN has, plus the consignment code, HP codes and register entry — more places to make a mistake.
• →The consignment code. A long unique reference that's easy to mistype or transpose by hand, and the whole movement hangs off it.
• →HP codes from memory. Nobody carries HP1–HP15 in their head; on paper people guess the hazard or leave it blank.
• →Three-year retention. A box of carbon copies has to survive a full three years and still be findable when a regulator asks.

How does digital software help hazardous carriers?

Digital software earns its place fastest exactly where the fields are hardest and the stakes are highest. Good software does the checking a paper book can't:

Validates the hazardous-specific fields

The consignment code, HP codes and asterisked EWC are captured as structured fields, not free text — so a note can't be finished with the hazard left blank or the code half-typed. The software flags what's missing before the driver leaves.

Guides HP-code and EWC selection

Predictive search across the full European Waste Catalogue flags hazardous (asterisked) entries, and HP1–HP15 are picked from a list rather than remembered. The driver selects the right hazard instead of guessing it.

Captures the consignment code at the roadside

The consignment note code is recorded on-site — offline if there's no signal — and tied to the movement, so it can't be transposed or lost between the job and the office.

Holds records for the full 3 years

Every consignment note and the consignment register are retained for the 3-year hazardous period and findable in seconds by customer, date, EWC code or vehicle — no box to dig through when a regulator asks.

Hazardous waste consignment notes and the consignment register must be kept for at least 3 years — a year longer than the 2 years required for ordinary waste transfer notes. Software should handle that retention for you.

How does ComplyWaste fit in?

ComplyWaste is our digital waste transfer note app, built around the driver on-site — and that includes the extra hazardous fields. It's offline-first, has predictive EWC search that flags hazardous codes, structured capture of the consignment code and HP codes, on-glass signatures with GPS, auto-emailed branded PDFs and a searchable archive that holds hazardous records for the full 3 years.

Every plan starts with a 14-day free trial and no card required. Pricing is published up front rather than hidden behind a demo call.
