4 . A method according to claim 1 , wherein the mobile refuse vehicle further includes an inlet valve arrangement operably coupled to the refuse collector and to the inlets of the first and second storage tanks, and alternating between the first and second operation modes include adjusting the inlet valve arrangement to open one of the inlets and close the other of the inlets.
5 . The method according to claim 4 , wherein the mobile refuse vehicle further includes an outlet valve arrangement operably coupled to the outlets of the first and second storage tanks, and alternating between the first and second operation modes include adjusting the outlet valve arrangement to open one of the outlets and close the other of the outlets.
6 . The method according to claim 1 , further comprising processing the refuse removed from the first or second storage tank, wherein processing includes separate a waste material from a carrier material.
7 . The method of claim 1 , wherein removing refuse from the first and second refuse storage tanks includes applying an atmospheric pressure condition to the storage tank from which refuse is being removed.
8 . The method of claim 1 , wherein each of the first and second refuse storage tanks includes a vacuum port, and the vacuum pressure condition is applied at the vacuum port.
9 . A method of operating a mobile refuse vehicle, the mobile refuse vehicle including first and second refuse storage tanks, a refuse collector, and a vacuum pressure source operably connected to the first and second storage tanks, the first and second storage tanks each include an inlet operably connected to the refuse collector and an outlet, the method including:
(a) initiating a first operation mode, the first operation mode including:
(i) opening the outlet and closing the inlet of the second storage tank;
(ii) closing the outlet and opening the inlet of the first storage tank;
(iii) creating a vacuum pressure condition in the first storage tank with the vacuum pressure source;
(b) collecting refuse through the refuse collector into the first storage tank after initiating the first operation mode;
(c) removing refuse from the second storage tank through the outlet of the second storage tank during the step of collecting refuse into the first storage tank;
(d) initiating a second operation mode after initiating the first operation mode, the second operation mode including:
(i) closing the outlet and opening the inlet of the second storage tank;
(ii) opening the outlet and closing the inlet of the first storage tank;
(iii) creating a vacuum pressure condition in the second storage tank with the vacuum pressure source;
(e) collecting refuse through the refuse collector into the second storage tank after initiating the second operation mode; and
(f) removing refuse from the first storage tank through the outlet of the first storage tank during the step of collecting refuse into the second storage tank.
10 . A method according to claim 9 , wherein the steps of removing refuse from the second storage tank and removing refuse from the first storage tank include exposing the first and second storage tanks to atmospheric pressure.
11 . A method according to claim 9 , wherein the mobile refuse vehicle further includes an inlet valve arrangement operably coupled to the refuse collector and to the inlets of the first and second storage tanks, the step of initiating a first operation mode includes adjusting the inlet valve arrangement to close the inlet of the second storage tank and open the inlet of the first storage tank, and the step of creating a second operation mode includes adjusting the inlet valve arrangement to open the inlet of the second storage tank and close the inlet of the first storage tank.
12 . A method according to claim 9 , wherein the mobile refuse vehicle further includes an outlet valve arrangement operably coupled to the outlets of the first and second storage tanks, the step of initiating a first operation mode includes adjusting the outlet valve arrangement to close the outlet of the first storage tank and open the outlet of the second storage tank, and the step of creating a second operation mode includes adjusting the inlet valve arrangement to open the outlet of the first storage tank and close the outlet of the second storage tank.
13 . A method according to claim 9 , wherein the first and second storage tanks each include a vacuum port, and the step of initiating a first operation mode further includes opening the vacuum port of the first storage tank prior to the step of creating a vacuum pressure condition in the first storage tank with the vacuum pressure source, and the step of initiating a second operation mode further includes opening the vacuum port of the second storage tank prior to the step of creating a vacuum pressure condition in the second storage tank with the vacuum pressure source.
14 . A mobile refuse vehicle comprising:
