The first holding tank is downstream from the ozone generator and defines a volume for liquid waste beneath a void space. The exhaust vent is downstream from the first holding tank and outside of the vehicle. A supply conduit connects the ozone generator to the void space of the first holding tank. An exhaust conduit connects the void space of the first holding tank to the exhaust vent. The ozone generator, supply conduit, void space of the first holding tank, exhaust conduit, and exhaust vent establish a thermal driving head from the ozone generator through the void space of the first holding tank to the exhaust vent. ## Claims ### Claim 1 A system for treating emissions from a vehicle, comprising: an ozone generator; a first holding tank downstream from said ozone generator wherein said first holding tank defines a volume for liquid waste beneath a void space; an exhaust vent downstream from said first holding tank and outside of the vehicle; a supply conduit that connects said ozone generator to said void space of said first holding tank; an exhaust conduit that connects said void space of said first holding tank to said exhaust vent; wherein said ozone generator, said supply conduit, said void space of said first holding tank, said exhaust conduit, and said exhaust vent establish a thermal driving head from said ozone generator through said void space of said first holding tank to said exhaust vent. ### Claim 2 (depends on 1) The system as in claim 1, wherein said ozone generator comprises an inlet, a chamber downstream from said inlet, an ultraviolet lamp inside said chamber, and an outlet downstream from said chamber connected to said supply conduit. ### Claim 3 (depends on 2) The system as in claim 2, wherein said outlet downstream from said chamber is translucent. ### Claim 4 (depends on 1) The system as in claim 1, further comprising a second holding tank downstream from said ozone generator. ### Claim 5 (depends on 1) The system as in claim 1, wherein said supply conduit has an elevation above said first holding tank. ### Claim 6 A system for treating emissions from a vehicle, comprising: a first holding tank wherein said first holding tank defines a volume for liquid waste beneath a void space; an ozone generator upstream from said first holding tank and in fluid communication with said void space of said first holding tank; an exhaust vent downstream from said first holding tank wherein said exhaust vent is in fluid communication with said void space of said first holding tank; wherein said ozone generator, said void space of said first holding tank, and said exhaust vent establish a thermal driving head from said ozone generator through said void space of said first holding tank to said exhaust vent. ### Claim 7 (depends on 6) The system as in claim 6, wherein said ozone generator comprises an inlet, a chamber downstream from said inlet, an ultraviolet lamp inside said chamber, and an outlet downstream from said chamber in fluid communication with said void space of said first holding tank. ### Claim 8 (depends on 7) The system as in claim 7, wherein said outlet downstream from said chamber is translucent. ### Claim 9 (depends on 6) The system as in claim 6, further comprising a second holding tank downstream from said ozone generator. ### Claim 10 (depends on 6) The system as in claim 6, further comprising a supply conduit that provides fluid communication between said ozone generator and said void space of said first holding tank, wherein said supply conduit has an elevation above said first holding tank. ### Claim 11 A system for treating emissions from a vehicle, comprising: a chamber; an axial flow path through said chamber; an ultraviolet lamp in said axial flow path through said chamber; a first holding tank downstream from said chamber wherein said first holding tank defines a volume for liquid waste beneath a void space; an exhaust vent downstream from said first holding tank wherein said exhaust vent is in fluid communication with said void space of said first holding tank; wherein said ultraviolet lamp, said void space of said first holding tank, and said exhaust vent establish a thermal driving head from said chamber through said void space of said first holding tank to said exhaust vent. ### Claim 12 (depends on 11) The system as in claim 11, wherein said chamber comprises a translucent outlet in fluid communication with said void space of said first holding tank. ### Claim 13 (depends on 11) The system as in claim 11, further comprising a second holding tank downstream from said chamber. ### Claim 14 (depends on 11) The system as in claim 11, further comprising a supply conduit that provides fluid communication between said chamber and said void space of said first holding tank, wherein said supply conduit has an elevation above said first holding tank.
