Green Products Company - Pith/Chaff PC Products

PC Products are made from the Pith & Chaff portions of the corncob.

Corncob Pellets
	Corncob Pellets - The pith and chaff portions of the corncob are extremely absorbent – about 300% on a weight-to-weight basis. However, those portions are light and fluffy (about 8 lbs. / cubic foot) and that makes them extremely difficult to handle and store. Consequently, we compress those components using a pellet mill and that increases the bulk density to about 45 pounds / cubic foot. Some corncob pellets are used as a composting media for growing mushrooms. Most of our pellets are re-ground to create particles similarly sized to grit particles.

1440 PC
	Passing U.S. Standard Screen #	Retained On U.S. Standard Screen #	Particle Size Distribution			1440PC is most often used as a “carrier” for pesticide applications. It is also used as an absorbent in environmental clean-up applications where it absorbs excess liquids in sludge. That process is also often described as a de-watering application.
