Riceland is also a major soybean processor in the Mississippi Delta region of the United States where milling, pressing, packaging and distribution occurs. It refines soybean and other vegetable oils for food service and food manufacturing companies. Soybean meal products are sold primarily to the poultry and catfish industries. In addition, winter wheat and limited quantities of corn are handled, depending on the needs of farmer-members. Bi-products that are commercially marketed include organic gardening amenities like PBH (pasteurized rice hulls) and rice hull ash which are bio-degradable and bio-renewable soil supplement replacements for perlite and vermiculite.
