TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The method further comprises providing a lining for the at least one concavity, and providing pumps, drains, drain matrices, sumps, leachate collection systems, valves, valve for directing or controlling the flow of fluids or leachate from the waste, and device for monitoring the content, conditions, or changes with respect to the waste contained in the facility; providing for device for controlling the conditions, content, and changes of the waste contained in the facility. During the applying of slurry to surface of the site, the drainage is positioned within the slurry, where the drainage can be pumps, pipes, drains, drain matrices, sumps, leachate collection systems, valves, valve for directing or controlling the flow of fluids or leachate from the waste, membranes, geomembranes, geosynthetic clay liners, felt, glass fibers, fiberglass, filtration fabrics, geonets, geotextiles, geogrids, geopipes, or geocomposites. The slurry is aqueous and is conveyed to the site by pipes or conveyors. The slurry comprises binders or cementitious additives such as Portland cement.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Components: The concavity has sheet like elements such as membranes, geomembranes, geosynthetic clay liners, felt, glass fibers, fiberglass, filtration fabrics, geonets, geotextiles, geogrids, geopipes, and geocomposites. The sheetlike elements functions as an impermeable liner for the concavity or as a permeable liner for the concavity. It may function as liners, filters, leachate collectors, sumps, permeable covers, impermeable covers, removable covers, permanent covers, microbial reservoirs, drains, drain matrices, partitions or subcontainers. The containment facility further comprises a cover system that is at least partially removable. The containment facility further comprises leachate sumps and leachate removal and processing systems. It further comprises drain(s), valves for directing or controlling the flow of fluids or leachate from the waste, and device for monitoring the content, conditions, or changes with respect to the waste contained in the facility. The device for monitoring includes data collection device, data forwarding device, data analysis device, gas detectors, gas identification sensors, chemical sensors, pressure sensors, temperature sensors, fluid flow sensors, pH sensors, gas sampling device, gas recovery device, microbial sensors and microbial condition sensors. The containment facility further comprises an element for controlling the conditions, content, and changes of waste contained in the facility. The concavity is formed completely from a gypsum stack.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The sheetlike elements comprise high-density polyethylene, ZFPE, TVC, and fPTR.
