Residential waste volume reduction arrangements

A system for reducing the volume of waste comprising:

• a frame;
• a hingable lid attached to the frame, the lid having a latch;
• a first sensor coupled to the frame to detect if the lid is in a closed position;
• a trash volume reduction chamber connected to the frame, the trash volume reduction chamber having at least a first shaft and a second shaft, each shaft having an axis and a plurality of knives projecting radially from their axis, the knives on the first shaft and the second shaft spaced such that from the knives on the first shaft interleave with the knives of the second shaft to define passages that to allow trash particles of a predetermined size to fall out of the volume reduction chamber, the frame to hold the reduction chamber above a mobile curb-side receptacle;
• a motor coupled to the frame;
• a power transmission system to couple the motor to the first shaft and second shaft
• a controller to reverse a direction of rotation of the first shaft and second shaft;
• and
• the first shaft and second shaft disposed in the trash volume reduction chamber, the motor to rotate the first shaft in counter relationship to the second shaft where the waste is fragmented reducing a volume of the waste.
