Abstract: A waste monitoring system includes a portable device to monitor product wastage. The portable device includes a processor and a memory in communication with the processor. The memory stores processor-executable instructions that, when executed by the processor, cause the processor to control operation of the portable device to generate a graphical user interface (GUI) to collect quantity data relating to respective quantities of a plurality of types of wasted products, and to calculate cost data as a function of the quantity data. A display device displays the GUI. A server is in communication with the portable device and is configured to receive the quantity data and the cost data from the portable device. A computing device is in communication with server and is configured to receive the quantity data and the cost data from the server and to display at least one of the quantity data and the cost data.
