Abstract
A synthetic cover for waste piles may be formed from a mixture of liquid, binder, and fibers. These constituents may be mixed and applied to cover a waste pile. The cover will harden to minimize odor and affinity to birds, flies and other insects. The liquid may include water; the binder may include cement kiln dust with or without bentonite, or portland cement with flyash or stone dust. The fibers may comprise shredded paper or wood.
