Abstract: A resource recovery system for recovering articles to be recycled as a resource includes a plurality of resource recovery apparatuses that recovers the discarded articles by a person discarding waste and a server apparatus that manages the plurality of resource recovery apparatuses. The server apparatus generates suggestion information including information indicating a suggestion for a location of a target resource recovery apparatus, based on a utilization result and a location of each of the plurality of resource recovery apparatuses. The target resource recovery apparatus is the resource recovery apparatus to be newly placed and/or the resource recovery apparatus that has been located and of which location is to be changed.

Abstract: A resource collection apparatus is an apparatus for collecting waste reusable as a resource. The resource collection apparatus includes an opening associated with a predetermined sorting type, an opening/closing unit configured to open and close the opening, a first detector configured to perform an operation to detect a target waste belonging to a user, and a controller configured to specify a sorting type into which the target waste is to be sorted, by using a result of the detection by the first detector. The controller switches the opening/closing unit from a closed state to an open state when the specified sorting type matches the sorting type associated with the opening.

Abstract: A resource recovery system is a system for recovering articles which can be recycled as resources. The resource recovery system includes a resource recovery apparatus that recovers the article discarded by a consumer, and a server apparatus that communicates with the resource recovery apparatus. The resource recovery apparatus transmits, to the server apparatus, a first message including an article identifier for identifying the recovered article. The server apparatus associates, based on the first message received from the resource recovery apparatus, a discarding time when the article is discarded with a provision time when the article is provided to the consumer.

Abstract: A fuel cell device according to the present invention includes a controller. The controller is configured to allow a fuel gas supply device and an oxygen-containing gas supply device to supply the fuel gas and the oxygen-containing gas supplied to fuel cells (19) in a supply amount less than a supply amount to be set in accordance with a decreased power as required by the external load as well as to cause an igniter to start operation if the power required by the external load decreases and flameout of the combustion in a combustor (45) is recognized.
