An impoundment closure system that employs a low permeability membrane on top of a waste materials with ponded water on top of the low permeability membrane.

Systems and methods are disclosed for landfill systems, comprising waste, a geosynthetic product, and a layer of foam glass aggregates interposed between the waste and the geosynthetic product.

A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for a job site. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for a job site.

A sediment capping system is adapted to create, and distribute, a homogenized mixture of capping material. Where distributing the capping material, the system is configured to militate against the capping material forming clumps of a size and weight that would disturb the sediment on a bottom of a body of water. This in turn militates against the sediment being disturbed, and a disturbing of pollutants and toxins into the water surrounding the sediment. The sediment capping system militates against the clumping of capping material through a vibrating spreader and baffle system, producing a sediment cap with a more consistent depth that will minimally disturb the sediment on the floor of the body of water where the sediment cap is being deposited.

An articulating mattress of blocks interconnected with tensiles seated therein, said blocks having opposing longitudinal and transverse sides and a top surface each of a smooth surface by contact with a mold surface during casting and a bottom surface having a rough surface by screeding the flowable casting material from an open side of a mold formwork. The mattress inverted with a rolling apparatus for installation with the rough surface in frictional contact on a ground surface for erosion control, said mattress rolling apparatus having base, front wheels, and steerable rear wheels, with a rolling mechanism for rolling the articulating mattress. An apparatus and a method of casting an articulable mattress with a rough bottom surface for erosion control are disclosed.

The invention disclosed herein includes apparatus and a method for enhancing the evaporation rate of leachate from leachate evaporator ponds. The HIAP apparatus and method promotes enhances evaporation by providing heat from high powered industrial heat lamps that direct heated air and heat energy across the air/leachate liquid interface of the evaporator pond surface to increase the evaporation rate of leachate from the evaporator pond.

A method for converting municipal solid waste to a stable solid fill-material (backfill) in the form of a multiplicity of compacted pieces, the method including mechanically reducing solid-waste piece size to form a solid-waste stream, heating the solid-waste stream and thereby killing bacteria in such stream, adding an antimicrobial agent to the solid-waste stream, and pelletizing the solid-waste stream.

An ecological reconstructed sponge structure of a strip mine dump includes a three-layered sponge ecological structure arranged on a groundmass layer of the dump. From bottom to top, the three-layer sponge ecological structure comprises a water-resisting layer, a water-containing layer and a topsoil ecological layer. A thickness of the water-resisting layer is 100˜200 cm, a permeability coefficient of the water-resisting layer is 0.35˜0.7 m/d, and a degree of compaction is 1200˜1400 KPa. A thickness of the water-containing layer is 150˜250 cm, a permeability coefficient of the water-containing layer is 10˜20 m/d, and a degree of compaction is 800˜900 KPa. A thickness of the topsoil ecological layer is 40˜60 cm. Soil layer thicknesses and water content may be monitored through a ground penetrating radar.

A pit cover for selectively covering a pit opening which provides access to an animal waste collection area. One or more of the edges may include a flange which a user may grip when lifting or moving the pit cover. The top side includes a plurality of raised ridges extending generally across its surface. The ridges help provide traction for a user walking on the pit cover. The longitudinal axis of one or more of the ridges may be set at an angle relative to the longitudinal axis of the front edge of the pit cover to allow water and other moisture to drain off of the top side. The pit cover may be made from any suitable material, including fiberglass. In embodiments where the pit cover is made from fiberglass, the ridges are part of the fiberglass mold which helps add strength by corrugation.
