Abstract: A recycling support system for a production facility performing a plurality of types of recycling processing using marine plants includes a measurement unit configured to measure an amount of remaining energy used to operate the production facility, and a control unit configured to control a proportion of each of the plurality of types of recycling processing carried out in the production facility according to the amount of remaining energy used to operate the production facility measured by the measurement unit.

Abstract: A feed pushing apparatus 1 includes a traveling body 11 which travels along a feeding path 5, a feed pushing blade 15 which is mounted to a frame 13 of the traveling body 11 and is capable of rising from the feeding path 5, and a first hydraulic cylinder 17 which is mounted to the frame of the traveling body 11, and reciprocally drives the feed pushing blade 15 between a stall 3 side and a side opposite from the stall, with movement of the traveling body 11. By reciprocating the feed blade by the first hydraulic cylinder 17, the feed positioned away from the stall can be pushed back to the stall side.
