Provided is a scaling and monitoring system for remotely weighing, monitoring, and measuring volumes of rubber buffings (also referred to in text as “shavings” or “dust”) produced by commercial tire retreading plants and other materials. The method utilizes a custom scale system installed underneath a shipping container or a semi van trailer, container, or other collection and storage unit or area. The custom scale system feeds weight data to a PLC and VPN/gateway-based control panel which processes and relays information to the Internet, thus allowing all accessible and recorded data to be remotely collected and viewed for the purpose of optimizing rubber dust collection and processing and minimizing overhead costs associated with such processes.
