Bin for collecting biological materials including a container having a bottom floor, side walls and a lid which can be opened, and at least one opening for the passage of air. Side gratings are arranged in an interior of the vessel and at a distance from an adjacent side wall. The gratings are connected to the vessel. A bottom grating is arranged at a distance from the floor of the vessel and pivotally mounted to the side gratings to pivot inward into a space between the side gratings. Intermediate spaces are present between the side gratings and the respective adjacent side wall and connected with the air passage opening(s). An insert for converting a commercial refuse bin into a bin of this type includes two side gratings and fastening or fixing elements for mounting the side gratings fixedly to the side wall of the refuse bin.

The system of claim 1, further comprising operational control means for controlling said direction of rotation of said motor, wherein said operational control means comprises a microprocessor. 3. The system of claim 1, further comprising a first check valve and a second check valve, wherein said first check valve prevents reverse flow of said hydraulic fluid through said first suction conduit and said second check valve prevents reverse flow of hydraulic fluid through said second suction conduit. 4. The system of claim 3, further comprising pressure relief means to release hydraulic fluid into said reservoir if said system is over-pressurized. 5. The system of claim 4, wherein said pressure relief means comprises a first pressure relief valve and a second pressure relief valve, wherein said first pressure relief valve communicates with said first delivery/return conduit and said second pressure relief valve communicates with said second delivery/return conduit. 6. The system of claim 4, wherein said means to balance flow comprises a differential flow control valve. 7. The system of claim 3, wherein said means to balance flow comprises a differential flow control valve. 8. The system of claim 1, further comprising pressure relief means to release hydraulic fluid into said reservoir if said system is over-pressurized. 9. The system of claim 8, wherein said pressure relief means comprises a first pressure relief valve and a second pressure relief valve, wherein said first pressure relief valve communicates with said first delivery/return conduit and said second pressure relief valve communicates with said second delivery/return conduit. 10. The system of claim 1, wherein said means to balance flow comprises a differential flow control valve. 11. The system of claim 1, wherein said means to balance flow comprises a shuttle valve. 12. The system of claim 1, further comprising a counterbalance valve to lock said actuator mechanism. 13. An hydraulic power system for operating an actuator mechanism comprising: a reservoir retaining an hydraulic fluid; an electrically powered reversible motor having a first direction of rotation and a second direction of rotation, wherein said motor is submerged in said hydraulic fluid within said reservoir, said hydraulic fluid acting as a heat dissipater for heat created by said motor; operational control means for controlling said direction of rotation of said motor, wherein said operational control means comprises a microprocessor; a pump driven by said motor for removing said hydraulic fluid from said reservoir and delivering said hydraulic fluid to an actuator mechanism; a first suction conduit and a second suction conduit for removing said hydraulic fluid from said reservoir, wherein the direction of rotation of said motor determines whether said hydraulic fluid is drawn through said first suction conduit or said second suction conduit; a first check valve and a second check valve, wherein said first check valve prevents reverse flow of said hydraulic fluid through said first suction conduit and said second check valve prevents reverse flow of hydraulic fluid through said second suction conduit; a first deliver/return conduit and a second delivery/return conduit for delivering said hydraulic fluid from said reservoir to said actuator mechanism, wherein the direction of rotation of said motor determines whether said hydraulic fluid is delivered through said first deliver/return conduit or said second delivery/return conduit; a first pressure relief valve and a second pressure relief valve, wherein said first pressure relief valve communicates with said first delivery/return conduit and said second pressure relief valve communicates with said second delivery/return conduit; and means to balance the flow of said hydraulic fluid when said direction of rotation is changed comprising a differential flow control valve. 14. A plural number of hydraulic power systems for operating an actuator mechanism, said hydraulic power systems connected in parallel such that hydraulic fluid can be delivered to said actuator mechanism by one or more of said hydraulic power systems each of said hydraulic power systems comprising: a reservoir retaining an hydraulic fluid; an electrically powered reversible motor having a first direction of rotation and a second direction of rotation, wherein said motor is submerged in said hydraulic fluid within said reservoir, said hydraulic fluid acting as a heat dissipater for heat created by said motor; a pump driven by said motor for removing said hydraulic fluid from said reservoir and delivering said hydraulic fluid to an actuator mechanism; a first suction conduit and a second suction conduit for removing said hydraulic fluid from said reservoir, wherein the direction of rotation of said motor determines whether said hydraulic fluid is drawn through said first suction conduit or said second suction conduit; and a first deliver/return conduit and a second delivery/return conduit for delivering said hydraulic fluid from said reservoir to said actuator mechanism, wherein the direction of rotation of said motor determines whether said hydraulic fluid is delivered through said first deliver/return conduit or said second delivery/return conduit; and further wherein each of said hydraulic power systems is controlled by operational control means which determines said direction of rotation of each said motor and determines which of said hydraulic power systems deliver hydraulic fluid to said actuator mechanism, wherein said operational control means comprises a microprocessor. 15. The system of claim 14, each of said hydraulic power systems further comprising a first check valve and a second check valve, wherein said first check valve prevents reverse flow of said hydraulic fluid through said first suction conduit and said second check valve prevents reverse flow of hydraulic fluid through said second suction conduit. 16.
