Waste containment systems

Technology Descriptions The use of thermoplastic solidification systems in radioactive waste disposal has led to the development of waste containment systems that can be adapted to industrial waste. In processing radioactive waste with bitumen or other thermoplastic material (such as paraffin or polyethylene), the waste is dried, heated and dispersed through a heated, plastic matrix. The mixture is then cooled to solidify the mass. [Pg.182]

Final cover systems are another important component of waste containment systems used at landfills. While liner systems are installed beneath the waste, final cover (or closure) systems are installed over the completed solid waste mass. For hazardous waste landfills, 40 CFR 264 requires that the landfill be closed with a final cover system that meets certain performance criteria, most notably, that they have a permeability less than or equal to the permeability of any bottom liner system or natural subsoils present. U.S. EPA guidance documents517 recommend that final cover systems for hazardous waste landfills consist of at least the following, from top to bottom ... [Pg.1102]

Figure 1 illustrates the components of municipal solid waste (MSW) landfill waste containment systems. MSW landfills are by far the most common type of engineered waste containment system, followed (with respect to frequency of occurrence) by cover systems (caps) for uncontrolled dumps and hazardous waste sites and then by hazardous waste landfills. Caps and containment systems for hazardous waste landfills employ similar elements to MSW landfills. The performance of ancillary facilities at a waste disposal site subject to seismic loading, including leachate and gas treatment facilities, surface water control systems, access roadways, and landfill monitoring systems, is also an important consideration but will not be addressed herein. [Pg.2823]

In general, the seismic performance of waste containment systems subject to strong ground motion from earthquakes has been acceptable, i.e., has not resulted in a harmful discharge of waste or waste by-products to the environment. [Pg.2823]

Table 1 summarizes typical values of acceptable calculated seismic displacement for non-geosynthetic components of landfill containment systems from a decoupled analysis, along with the anticipated duration for the interim and final repairs of these components. For the geosynthetic elements of waste containment systems, 150 mm of calculated displacement is generally considered to be indicative of no damage, and up to 3 m of displacement may be considered acceptable for geosynthetic elements in which... [Pg.2832]

Seismic design of waste containment systems is an important consideration with respect to both maintaining the protection afforded by the containment system for human health and the environment and providing safe and secure capacity for waste disposal during earthquake response and recovery operations. Important engineering considerations with respect to the seismic design of waste containment systems include the seismic... [Pg.2834]
