Question 1

Is WTN App an official DEFRA product?

Accepted Answer

No. DEFRA is building the backend API for digital waste tracking. They expect private companies to build the tools that carriers actually use. That's us. We sync directly with DEFRA's system.

Question 2

What is an EWC code?

Accepted Answer

EWC stands for European Waste Catalogue (also called List of Waste or LoW codes). Every type of waste has a 6-digit code — like 17 09 04 for mixed construction and demolition waste. You need the right code on every waste transfer note.

Question 3

Does it work without internet?

Accepted Answer

Yes. The app works fully offline. Notes are saved on your phone and sync to DEFRA automatically when you're back in signal. Built for skips on rural sites with no reception.

Question 4

When does the DEFRA mandate start?

Accepted Answer

Waste receiving sites must use digital waste tracking from October 2026. Carriers follow from October 2027. But if you're transferring to a site that's already digital, you'll need to be ready by October 2026.

Question 5

Can I use this for hazardous waste?

Accepted Answer

Yes. WTN App includes all hazardous EWC codes and flags them clearly. Hazardous waste has additional consignment note requirements which we handle automatically.

Question 6

How long do I need to keep waste transfer notes?

Accepted Answer

By law, waste transfer notes must be kept for a minimum of 2 years (3 years for hazardous waste consignment notes). WTN App stores everything digitally so you never lose a note.
