1. A two-stage flush system for use in connection with a vacuum toilet, wherein the vacuum toilet is configured to be plumbed in-line with a main waste line that leads to a main waste holding tank, comprising: (a) a vacuum toilet bowl,(b) a transient waste tank plumbed in-line between the vacuum toi
1. A two-stage flush system for use in connection with a vacuum toilet, wherein the vacuum toilet is configured to be plumbed in-line with a main waste line that leads to a main waste holding tank, comprising: (a) a vacuum toilet bowl,(b) a transient waste tank plumbed in-line between the vacuum toilet bowl and the main waste holding tank,(c) a first valve positioned between the vacuum toilet bowl and the transient waste tank; and(d) a second valve positioned between the transient waste tank and the main waste line, the second valve comprising (1) a valve housing enclosing a flush plate;(2) the valve housing comprising a first opening and a second smaller vent opening;(3) the flush plate comprising a first opening, a second smaller vent opening, and an axis of rotation,wherein rotation of the flush plate with respect to the axis of rotation either (i) closes the first and second openings of the housing, (ii) allows the first opening of the housing to be open by aligning the first opening of the housing with the first opening of the flush plate, or (iii) allows the second opening of the housing to be open by aligning the second smaller vent opening of the housing with the second smaller vent opening of the flush plate, such that the waste tank is exposed to vacuum through the second smaller vent opening without evacuating waste from the vacuum toilet,wherein the flush plate prevents both the first and second openings of the housing from being simultaneously open. 2. The valve of claim 1, wherein movement of the flush plate is activated by a vacuum sensor, a pressure sensor, a capacitance sensor, or a level sensor. 3. The valve of claim 1, wherein movement of the flush plate is activated by a manual activation feature. 4. The valve of claim 1, wherein the position of the first and second openings on the housing correspond in size and spacing to the first and second openings of the flush plate. 5. The valve of claim 1, wherein when the first opening of the housing is aligned with the first opening of the flush plate, the second smaller vent opening of the housing cannot be aligned with the second smaller vent opening of the flush plate. 6. The valve of claim 1, wherein the housing comprises at least one additional opening. 7. The valve of claim 1, wherein the housing comprises a metallic material. 8. The valve of claim 1, wherein the housing comprises plastic, a thermoplastic resin, a polymeric material, polyetherimide, nylon, polypropylene, acrylonitrile butadiene styrene, polyethylene, stereolithography resin, carbon composite material, carbon fibers in an epoxy matrix, polycarbonate, or any combination thereof. 9. The valve of claim 1, wherein the flush plate comprises a metallic material. 10. The valve of claim 1, wherein the flush plate comprises plastic, a thermoplastic resin, a polymeric material, polyetherimide, nylon, polypropylene, acrylonitrile butadiene styrene, polyethylene, stereolithography resin, carbon composite material, carbon fibers in an epoxy matrix, polycarbonate, or any combination thereof. 11. The valve of claim 1, wherein the flush plate is coated with a non-corrosion material, a non-stick material, or a combination thereof. 12. The valve of claim 1, wherein the flush plate comprises a half moon shape.
