ABSTRACT:
A method of making a biodegradable non-polluting product includes grinding an agricultural fibrous material to form a particulate material; preparing a binder by mixing formaldehyde with carboxymethyl cellulose and polyvinylalcohol; mixing the particulate material with a stearate and a sulfate to form a first mixture; adding the binder and water to the first mixture to form a second mixture; and forming the second mixture into the non-polluting product. The fibrous material may be an agricultural fibrous waste material. The products made by the method contain no toxic material.
