Removing waste from an oilfield rig

A method for storing or disposing waste from an oilfield rig, comprising:

• receiving waste from an oilfield rig into a volume of a container sized to receive and store the waste;
• operating, with a powered arm, a compression plate positioned in the volume to move from a retracted position in the volume to an extended position in the volume, the compression plate sized to extend between and orthogonal to two sides of the container and in planar parallel with a back wall of the container;
• compressing, with the compression plate, at least a portion of the waste in the volume as the compression plate moves from the retracted position into the extended position;
• and
• opening an adjustable door connected to the container opposite the back wall to swing away from the container to expose the compressed waste in the volume to an external environment through the opened door.

An oilfield rig system, comprising:

• at least one oilfield rig;
• and
• at least one waste disposal system comprising:
• a container that defines a volume sized to receive and store waste from the oilfield rig,
• a compression plate positioned in the volume, the compression plate sized to extend between and orthogonal to two sides of the container and in planar parallel with a back wall of the container,
• at least one powered arm connected to the compression plate, and
• an adjustable door connected to the container opposite the back wall;
• and
• a control system communicably coupled to the at least one powered arm and the adjustable door and configured to perform operations comprising:
• operating the at least one powered arm to adjust the compression plate between a retracted position in the volume adjacent the back wall and an extended position to compress the waste into at least one portion of compressed waste, and
• operating the adjustable door to swing away from the container to release the at least one portion of compressed waste from the volume.
