The product is an IoT platform for monitoring and managing industrial waste compactors deployed at customer locations. Each compactor has a connected hardware board that sends operational data to the cloud. The platform uses AWS services to collect and process this data, monitor device status, support operational dashboards, and trigger actions on remote devices.

The system is also used to manage and monitor things such as device connectivity, compactor activity, pickup/haul information, alerts, and automated communications.
