How it works...
Pneumatic collection operates on a simple principle, enhanced by modern computer technology and processor controls.

As a sailboat is pushed by the wind, trash is pushed through stainless steel pipes to a collection area up to 1.5 kilometers away where it is collected, compacted and contained for subsequent hauling to a recycling center or landfill. 

The moving air is generated by energy efficient electric-powered ventilators which generate sufficient air speed and volume to move up to 200 metric tons of trash per day at speeds up to 30 meters per second (approximately 67 miles per hour).  Its path through the underground stainless steel pipes is controlled by computer-operated valves which direct it to its proper final destination.

As many as 600 collection boxes or intake doors can be located throughout a project in which users deposit daily, household trash. Underground, temporary storage areas can be emptied when full or at specific times of the day, removing residential and commercial trash from a very large urban or residential area.  Up to 40,000 residents or users can be served with a single system.  Within a project, hotels, restaurants, offices, convention facilities, sports arenas, outdoor areas, and residences can be served.

Compared to conventional trash collection methods, much less fuel is consumed, noise pollution is eliminated and truck traffic on neighborhood and city streets is reduced.

In hospitals and hotels, both soiled linen and trash are collected in parallel pipes, using a compact arrangement of operating equipment, minimizing the use of building space.  Laundry and trash carts do not occupy elevator space as soiled linen and trash are collected.  Cross contamination is eliminated.  Housekeeping manpower is conserved, allowing a short 4 year payback for a typical system.
