A modular assembly for regulating moisture and temperature of content of a container, and method associated thereof. The system includes a moisture and temperature regulating device with a condenser and an evaporator separated by a heat insulation layer; a container with moist content, the container and the moisture and temperature regulating device are joinable, and moisture and temperature associated with the container are regulated by the moisture and temperature regulating device.

Freezer for biosanitary and cytotoxic waste, which comprises an inner space that houses a waste container, a front door through which the waste container in the inner space is inserted/removed, an upper door through which waste is poured into the inner container, cooling means and inner space temperature control means, wherein, the freezer further comprises an air purifier that treats an air stream coming from the inner space, when opening one of its doors, thus avoiding the emission of both chemical and biological particulate contaminants to the outside environment.

The present invention provides, among other things, a garbage, trash, and waste storage container including a heat exchanger operable to reduce the temperature of garbage, trash, and waste located in an interior of the container in order to reduce or eliminate odor causing bacteria from the garbage, trash, and waste. In some embodiments, the container includes a controller. In some such embodiments, the controller operates the heat exchanger to reduce an interior container temperature and to maintain the temperature of the interior of the container below a pre-determined temperature. In some embodiments, the garbage, trash, and waste storage device generates cold air inside of the garbage, trash, and waste storage device with at least one cooling mechanism that is powered by an electrical cord and plug that is plugged into an electrical wall socket. The garbage, trash, and waste storage device is designed to cool the garbage, trash, and waste while the garbage, trash, and waste is inside the garbage, trash, and waste storage device.

A waste compression device with a fee calculation function is provided for shaking and compressing wastes and calculating the quantity of the wastes. The waste compression device includes a casing. The casing has therein: a storage cart; a compression unit for compressing the wastes in the storage cart; a vibration unit for shaking the storage cart; a quantity sensor; a storage level sensor; an interface unit; and a control unit. The control unit controls the compression and vibration. The interface unit determines the best time to shake and compress the wastes according to the wastes level, and instructs a ticketing unit to dispense a coupon for joining a points reward scheme or receiving a cash discount or a gift according to the wastes quantity. The waste compression device calculates the quantity of the wastes, reduces the volume of the wastes, and encourages consumers to take the initiative in recycling wastes.
