How Decoset optimized its waste management with AI

Decoset, the waste treatment authority for the Toulouse region, engaged Akanthas to automate and improve the reliability of waste characterization.

Decoset, a waste treatment union in the Toulouse region, has asked Akanthas to automate and improve the reliability of waste characterization.

Challenge

Manual audits: costly, slow, and rarely representative

Before Akanthas, Decoset was running into structural limits in its characterization work. Audits were done manually, tying up several hours of labor for a cost that often exceeded €1,500 per characterization. This point-in-time format made it impossible to track how the waste stream was evolving — or to get a reliable view of flows over time.

These operations also exposed teams to safety risks, since workers had to handle waste directly during analyses.
On top of that, a major difficulty remained: clearly proving to downstream facilities that the flows being sent out met sorting requirements.

The stakes were therefore multiple:

  • Reduce the high cost of characterization.
  • Save time in audit execution.
  • Get a reliable view of the waste stream.
  • Limit the risks tied to manual waste handling.
  • Clearly justify downstream flow compliance.

Solutions

AI-automated characterizations

To address these operational constraints, Decoset deployed Akanthas’ Waste Quality solution within a transfer unit that handles the mixed bulky waste flows coming from all its drop-off centers. The technology fully automates the characterization of bulky waste flows, replacing manual audits with a fast, precise, and reproducible visual and algorithmic analysis.

With Akanthas, teams can analyze drop-offs without physically handling waste. Material types are identified automatically and compiled into reports that technical teams and local authorities can put straight to use.

This new approach delivers a finer view of the waste stream — making it easier to decide where to act, what to communicate, and how to raise awareness.

  • Deployment of the analysis solution for bulky waste flows.
  • Automatic identification of waste types.
  • Generation of reliable, ready-to-use reports.
  • Measurement of the recoverable share to fine-tune awareness campaigns.
“Beyond the time savings, what won us over with the Akanthas solution was the quality of the information. The data we receive on the platform is highly detailed — it goes beyond what we expected.”

Benefits

Immediate gains on cost, time, and sorting quality

From the very first uses, Decoset saw significant results — both operational and economic. Characterization, which used to take nearly four hours and tie up several staff members, is now done in a few minutes.

The total cost has been divided by five compared with a traditional manual audit.

The data generated also allows Decoset to fine-tune sorting guidelines based on local specifics and adapt awareness campaigns to the recoverable waste share observed. The organization can now also justify the compliance of flows sent downstream — reinforcing transparency across the process.

Finally, eliminating manual handling entirely reduces the risk to teams. Characterizations are now carried out safely, visually, and automatically.

“What’s great with this system is that we spread everything out on the ground (…) and we can prove to the partners we work with that sorting rules are being followed.”
