The premise

A single hidden battery can set a recycling facility ablaze. cellhound Sentry™ watches the sorting belt, and warns manual pickers of a battery’s location. 

How it works

From blind spot to caught in time

  1. 01

    Sense

    Advanced magnetic field sensors sit beneath the conveyor belt, scanning items at full speed. No line of sight required.

  2. 02

    Detect

    Machine learning models identify any metal-containing items by the perturbations they leave in the magnetic field. This includes WEEE, vapes, copper wire, and assorted aluminium and iron items.

  3. 03

    Act

    Sentry™ uses a spotlight to indicate hazard locations to manual pickers, supercharging their performance.

  4. 04

    Report

    Get real-time alerts of contamination, hazards, and blockages on a live dashboard. CellHound also reports on waste-stream composition and recovery rates, turning your line into a continuous source of material flow intelligence.

Built for your line

Designed for existing MRFs

No robotics. No rebuild. Sentry™ installs under your existing belt at the pre-sort stage, the first place a battery can be caught and pulled by hand, long before it reaches the machinery that can rupture it and start a fire.

Mechanical sort

Baler

Catch batteries in pre-sort and stop them in their tracks. Protect downstream sorting machinery and balers from fires. Safeguard bales from contamination by dangerous hazards.

The stakes

Escalating costs for the recycling industry

Hidden lithium-ion batteries are setting fires across the recycling system, and the problem is accelerating fast. These are the numbers driving the urgency.
