Use of Infrared Thermal Imaging Cameras in Recycling Centre Fire Detection

Waste recycling and sorting centre with conveyors and storage areas

Preventive monitoring of a waste sorting and recycling centre with an infrared camera end-to-end system

Almost 1 billion tonnes of waste is generated worldwide each year, which is then disposed of and recycled in many countries via a comprehensive system of waste recycling plants. Heat is often produced during the waste sorting process, culminating in hot zones, which can ultimately cause devastating fires. An early fire detection system using infrared cameras can promptly detect and remove the hazard.

Delivery vehicles transport the waste to the recycling plants and tip the material into a bunker. The bunkers have different storage capacities, for example, they could be 14,000 cubic metres holding roughly 7,000 tonnes of waste. Waste storage produces heat, often leading to the formation of hot zones.

Waste sorting plant conveyors filled with various household waste. Modern waste processing.

A gripper is used to automate the transport of the waste to the charging hopper, creating heat displacement and other physical effects, which may cause a fire in the refuse bunker. As a result, not only is the plant decommissioned for a few hours, but costly clean-up operations must be carried out as well.

Infrared cameras are able to measure temperature differences very precisely. The waste in the refuse bunker can be easily observed 24/7 by integrating the cameras and accessories. This thereby ensures a prompt response to potential hazards. When combined with other detection systems, e.g., traditional smoke detectors, a sprinkler system can be automatically deployed. The ultimate goal is to monitor the entire process using infrared cameras. The size of the bunker determines the number of cameras used.
