A recycling ship configured to sail to an offshore site for recycling a composite material rich structure at the site. The composite material rich structure can include a wind turbine blade, a boat or a ship comprising fiber reinforced composite material. The recycling ship comprises a first processing unit having a cutter configured to receive the composite material rich structure and to section it into composite parts, and a second processing unit having a crusher and/or grinder configured to reduce the size of the composite parts into composite material granulates.

A food waste disposer includes: a housing; a grinding case positioned inside the housing and configured to be separable from inside of the housing to outside of the housing and treat food waste; a rotating grinder configured to treat the food waste by rotating inside the grinding case and rotatably coupled with respect to a bottom surface of the grinding case; a grinder rotating shaft inserted in the rotating grinder and configured to rotate together with the rotating grinder; and a driver positioned below the grinding case and configured to provide rotation power of the rotating grinder, wherein the driver includes: a driving motor configured to generate power; a shaft driving gear configured to rotate by receiving power of the driving motor; and a connecting shaft configured to be rotatable within a range of a first angle with respect to the shaft driving gear, wherein one end of the connecting shaft is inserted in the grinder rotating shaft and another end of the connecting shaft is inserted in the shaft driving gear to transfer power from the shaft driving gear to the grinder rotating shaft.

Baffles for food waste disposers, systems employing such baffles, and methods of assembling, manufacturing, fabricating, or operating such baffles or baffle systems are disclosed herein. In one example embodiment, a baffle for implementation in connection with a food waste disposer includes a rim portion, a plurality of flaps, and a plurality of living hinges, wherein the rim portion, living hinges, and flaps constitute a single integrally-formed structure. The respective living hinges permit the respective flaps to be rotatable about respective axes that respectively are substantially tangent to respective locations along or proximate to the rim portion, so that the respective flaps can be rotated to respective closed positions. Either the living hinges or at least one additional component tend to cause the respective flaps to remain at the respective closed positions or to return to the respective closed positions when not at the respective closed positions.

A food waste disposer includes a housing, a grinding case inside the housing to dispose of food waste, a valve assembly mounted to a lower portion of the grinding case, and a driving device arranged on one side of the valve assembly to operate the valve assembly. The grinding case includes a discharge hole formed on a bottom surface. The valve assembly includes a valve member configured to open or close the discharge hole. The driving device includes: a driving motor to generate power; a power transmission member connected to the driving motor and configured to be moved in a first direction and a second direction opposite to the first direction; a holding member that rotates based on the movement of the power transmission member and connects to the valve member to guide an open or closed state of the valve member; and a sensor in contact with the power transmission member.

A food waste disposer includes: a housing; a grinding case positioned inside the housing, configured to grind food waste, and separable from the housing, wherein a discharge hole is formed in a bottom of the grinding case; a valve assembly coupled to the grinding case below the discharge hole and configured to open or close the discharge hole, the valve assembly protruding below the grinding case; a storage case positioned below the grinding case and configured to store the grinded food waste from the grinding case; a transfer tube positioned between the valve assembly and the storage case and configured to transfer the grinded food waste from the grinding case to the storage case; and a connector coupled to the transfer tube, wherein a shape of the connector is deformable upon the valve assembly resting on the connector.

The present invention relates to a glass panel recycling mechanism, which includes a material inlet provided on one side of a working space of a base for preset waste materials to enter, a transfer unit provided on the base to transport the preset waste materials by driving a plurality of transfer wheel sets through a driving device, a processing unit installed on the base below the transfer unit, a power unit for driving multiple crushing wheel cutter sets to press and break the glass panels on the surfaces of the preset waste materials, a collection device installed at the bottom of the base below the processing unit for collecting the waste of the preset waste materials to sent the waste to the outside by a conveyor belt so that the glass panels on the surfaces of the preset waste materials can be processed.
