INTRODUCTION
The InSinkErator
®
Waste Xpress
®
is a
Foodservice kitchen waste reduction
system that utilizes a standard Foodservice
disposer in line with the Waste Xpress
dewatering system. The kitchen waste
is ground through the disposer then
transferred to the Waste Xpress where
it is compressed. After the waste is
compressed, the liquids are sent down the
drain line and the solid waste exiting the
Waste Xpress is up to 85% less in volume
(see Figure 1 for typical installation).
