Abstract: An apparatus includes solar panels. The apparatus includes a battery system. The top surface of the battery system attaches to a bottom surface of the solar panels, and a bottom surface of the battery system has blocks that fit through apertures within the grooves of a dumpster lid. The apparatus includes a sensor system. The sensor system is attached to a bottom surface of the battery system, and a top surface of the sensor system has a corrugated design that fits into the bottom surface of the battery system. The apparatus includes a microprocessor. The microprocessor sends electronic information to a computing device. The electronic information includes one or more electronic images, and distance information between a top surface of garbage within a dumpster and a bottom surface of the sensor system.

Abstract: An apparatus, comprising a camera, a motion sensor, a receiving section, gas tanks, a screen, and a computing device. The computing device is configured to control the camera to take electronic images, determine a type of food placed in a particular container, determine an amount of gas and a type of gas to fill the particular container, generate an electronic message to request placement of the particular container onto the receiving section, and inject gas into the particular container when the particular container is placed onto the receiving section. The injected gas is used to preserve food inside the container.
