Haigh products are based on the simple system of fluid borne waste being controlled and reconstituted to make it easier to dispose of or handle.
This is primarily by cutting or macerating into small particles, sometimes preceded by screening to concentrate the solids within a flow. This is either sent directly to the waste drain or further refined by dewatering, compacting and heating to reduce volume and moisture, the benefit being a reduced requirement for disposal of residual solids.

Investment in new technologies for the manufacturing process is constantly assessed and when appropriate introduced. In the last few years, computer developments, sheet metal laser
