Abstract: A cover composition that can be applied to a bulk material pile, such as landfill refuse, to protect the pile from wind, precipitation, and access by animals and insects is provided. The cover composition is a mixture of a liquid, typically, water; bentonite clay; and synthetic fibers. The composition may be enhanced by the addition of one or more of the following additives: Portland cement, pregelatinized wheat starch, synthetic polymers, soda ash, and latex paint. Unlike prior art cover compositions, the disclosed composition adheres well to waste material, most notably plastics, whereby the composition is easy to apply and provides a substantially uniform, durable protective cover to landfill refuse piles and other bulk materials. Methods of applying the composition to bulk material piles are also disclosed.

Abstract: Systems, methods, and apparatus for servicing landfill conduits are disclosed. These systems, methods, and apparatus employ structures which facilitate access to and the servicing of buried landfill conduits, for example, one or more buried landfill laterals. In one aspect, the systems include an enclosure, at least one inlet conduit passing into the enclosure, at least one outlet conduit passing out of the enclosure, and at least one service conduit having a valve and an access port positioned between the inlet conduit and the outlet conduit. In another aspect, methods and portable apparatuses are provided for introducing high-pressure fluids or vacuum to a landfill conduit, for example, by means of the access port in the service conduit, to remove or dislodge obstructions. Conduits connected to blowers and pumps are used to introduce or withdraw fluids from the landfill conduits, for example, from predetermined locations within the landfill conduits identified by remote sensing devices.

Abstract: A synthetic cover for bulk material piles and loads in transit 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 water infiltration, wind blown dust, odor and affinity to birds, flies and other insects. The liquid may include water; the binder may include portland cement, portland cement with flyash, cement kiln dust with or without bentonite, or stone dust. The fibers may comprise shredded paper or wood or plastic fibers.

Abstract: A high efficiency waste placement and disposal method for disposing of solid waste in a landfill includes size reducing the solid waste, moisture adjusting the solid waste, placing the solid waste in a preselected geometric form thereby forming a waste pile, coating the exposed portion of the waste pile with a synthetic covering compound comprising a liquid, binder, cellulose fibers, and plastic fibers, biostabilizing the waste pile and compacting the waste pile. The waste is preferably placed in a matshaped stockpile for efficient biostabilization through sufficient aeration and moisture adjustment and compaction.
