Which Code Applies?

The European Waste Catalogue codes waste by the process it arises from, not just the material. Pick the row that matches where your septic tank sludge is generated — each code links to its full classification, valorisation routes and receiving industries.

Simulate your 20 03 04 stream

Septic Tank Sludge

With a lab analysis, the engine checks the stream against each receiving route's published limits and returns what is supported, what is refused, and why. Without one yet, we tell you which routes it can evaluate and what analysis that needs.

What do you need?

An engineer replies within 1 business day. That reply confirms what is needed to run the dossier and when it can follow. A route the engine does not cover yet is reported as not yet evaluable, with the evidence that would change that.
