c) environmentally controlling the transport chamber such that each pellet remains substantially solid during transport.
21 . The method of claim 20 , wherein a plurality of vents are defined in the transport chamber, and wherein environmentally controlling the transport chamber comprises drawing ambient air into the transport chamber through the plurality of vents.
22 . The method of claim 21 , wherein the vehicle comprises a train and wherein the transport chamber comprises a rail car.
23 . The method of claim 21 , wherein the vehicle comprises a truck.
24 . The method of claim 21 , wherein at least some vents in the plurality of vents including a screen configured to concurrently permit airflow into the transport chamber and block egress of pellets in the plurality of pellets from the transport chamber.
25 . The method of claim 20 , wherein each pellet of the plurality of pellets is further configured with an internal web structure disposed in the non-volatile bituminous materials.
26 . The method of claim 25 , wherein the internal web structure comprises a polymer.
27 . The method of claim 26 , wherein the internal web structure comprises a plurality of buoyant features, the plurality of buoyant features comprising pockets of gas formed within the polymer of the internal web structure.
28 . The method of claim 20 , wherein each pellet of the plurality of pellets comprises a coating covering the non-planar surfaces.
29 . The method of claim 28 , wherein the coating is a non-stick coating.
30 . The method of claim 20 , wherein one or more passive environmental control systems are defined in the transport chamber.
31 . The method of claim 20 , wherein environmentally controlling the transport chamber comprises controlling a temperature of the transport chamber.
32 . A method of moving bituminous material from a first location to a second location comprising:
a) providing a transport chamber comprising an environmental control system;
b) collecting a plurality of pellets in the transport chamber at the first location, wherein each pellet in the plurality of pellets comprises non-volatile bituminous material formed into an irregularly shaped solid defined by a plurality of non-planar faces configured to reduce surface contact with adjacent pellets to mitigate against caking of the plurality of pellets in the transport chamber;
c) transporting the transport chamber and the plurality of pellets collected therein to the second location with a vehicle; and
d) with the environmental control system, environmentally controlling the transport chamber during transport such that each pellet in the plurality of pellets remains substantially solid.
33 . The method of claim 32 , wherein each pellet of the plurality of pellets is further configured with an internal web structure disposed in the non-volatile bituminous materials.
34 . The method of claim 33 , wherein the internal web structure comprises a polymer.
35 . The method of claim 34 , wherein the internal web structure comprises a plurality of buoyant features, the plurality of buoyant features comprising pockets of gas formed within the polymer of the internal web structure.
36 . The method of claim 32 , wherein the environmental control system includes a sensing system for detecting an occurrence of softening of pellets in the plurality of pellets.
37 . The method of claim 32 , wherein the environmental control system includes a temperature sensing system for obtaining temperature measurements inside the transport chamber, the temperature sensing system including one or more temperature probes.
38 . The method of claim 37 , wherein the environmental control system includes an alarm, said environmental control system being configured to trigger said alarm in response to the temperature measurements inside the transport chamber exceeding a temperature threshold.
39 . The method of claim 32 , wherein the environmental control system includes a cooling device and wherein environmentally controlling the transport chamber comprises using the cooling device to lower a temperature inside the transport chamber.
40 . The method of claim 39 , wherein the cooling device is an active cooling device with a refrigeration cycle.
41 . The method of claim 39 , wherein:
a) the vehicle comprises at least one of truck and a train and the transport chamber comprises a rail car,
b) the cooling device includes a plurality of vents formed in the transport chamber, and
e) environmentally controlling the transport chamber comprises drawing air into the transport chamber through the plurality of vents.
42 . The method of claim 32 , wherein each pellet of the plurality of pellets comprises a coating covering a surface of each pellet, said coating being a non-stick coating.
43 . The method of claim 32 , wherein a protective liner covers an inside surface of the transport chamber to protect inside walls of the transport chamber from direct contact with the plurality of pellets.
