ABSTRACT:
The present invention is a system for adding colorant to pre-comminuted material. The colorant dispensing system includes a supply hopper to selectively retain and discharge dry colorant. The colorant dispensing system further includes a colorant dispensing assembly to receive dry colorant from the supply hopper and dispense dry colorant onto pre-comminuted material (M) before it is processed by a waste reducing section of a waste reducing machine. The present invention is also a method of dispensing colorant onto pre-comminuted material before processing by a waste reducing machine. The method includes the steps supplying dry colorant from a supply hopper to a colorant dispensing assembly and dispensing a controlled amount of dry colorant through the apertures onto pre-comminuted material prior processing the pre-comminuted material by a waste reducing section of a waste reducing machine into colored mulch.
