Solid waste asbestos

Asbestos is an airborne contaminant (Section 3.3.2), a hazardous solid waste (Section 3.5), and also a waterborne contaminant, regulated by many states. The health effect of asbestos in water, however, is not totally known. 

Small quantities of hazardous solid wastes (such as potassium dichromate, lead nitrate, silver nitrate, asbestos, etc.), liquid chemicals (such as chloroform, PCB, methylene chloride, etc.), petrochemicals (such as gasoline. No. 2 fuel oil, etc.), or pure metals (such as mercury, sodium, etc.), which are stored in bottles or cans, however, are not considered to be hazardous household products. Accordingly these nonhousehold hazardous solid wastes, even in small quantities, can only be properly disposed of by licenced or certified environmental professionals. 

According to the vendor, ZEROS can treat hydrocarbons and chlorinated compounds such as polychlorinated biphenyls (PCBs) and dioxins. The vendor claims that the technology can treat contaminated soils, liquid wastes in metal and plastic containers, asbestos, medical and biomedical wastes, contaminated sludges, waste fuels, fuel residues, and municipal solid waste. The technology is commercially available. 

C. Solid Waste. Regulations for the disposal of asbestos vary with locality but usually involve sealing the wastes in impermeable containers for final disposal by a licensed agent. 

List any special hazardous solid waste products, and the procedure for handling same, e.g. asbestos. 

Applicability Most hazardous waste slurried in water can be mixed directly with cement, and the suspended solids will be incorporated into the rigid matrices of the hardened concrete. This process is especially effective for waste with high levels of toxic metals since at the pH of the cement mixture, most multivalent cations are converted into insoluble hydroxides or carbonates. Metal ions also may be incorporated into the crystalline structure of the cement minerals that form. Materials in the waste (such as sulfides, asbestos, latex and solid plastic wastes) may actually increase the strength and stability of the waste concrete. It is also effective for high-volume, low-toxic, radioactive wastes. 

Handling hazardous ehemieals has beeome part of most people s everyday living. Just eonsider gasoline, and how most people fill their own tanks. In the manufaeturing arena, ehemieals are eommonplaee. On hazardous waste sites there are a variety of unknown ehemieal substanees and other hazards that may take the form of a solid, liquid, or gas. The eflfeets of exposure to toxie ehemieals may either be immediate (e.g., aeid burns) or delayed (e.g., lung damage from inhaling asbestos). There are four routes of ehemieal exposure that exist ... 

Founded as the National Asbestos Council, EIA is a resource for professionals in the management and control of health hazards to occupants of buildings, facilities, and industrial sites. It de >elops and disseminates information about asbestos, lead based paint hazards, underground storage tanks (USTs), indoor air quality, solid and hazardous waste. 

Chemically inactive These are made from a variety of materials that include wound yarn, felt, flannel, cotton waste, wood pump, mineral wool, asbestos and diatomaceous earth. The solid particles are trapped and retained within the medium. Certain types will remove water, as well as large and small particles of solids in a range down to 10 microns. Ceramics are sometimes employed for depth filtration, as also are special sintered metals. 

The Universal Demercurization Process, or UNIDEMP , is an ex situ process for removing mercury from a variety of solid and aqueous mercury waste streams such as metals, concrete, soils, asbestos, plastic, and cable as well as amalgams and mercury compounds. The process can also treat polychlorinated biphenyls (PCBs) and halogenated organics. UNIDEMP is a mobile system that volatizes and condenses mercury in a countercurrent rotating furnace at temperatures from 550 to 650°C. Celsius. 

Plasma torch—based applications for waste treatments include fly ash from incineration processes, asbestos-containing waste, sanitary waste, waste containing organo-halogenated compounds, low-level radioactive waste, and even traditional RDF. In particular, plasma applications represent a very interesting technical solution for the treatment of fly ash from MSW/RDF incineration because the solid by-product, with its extremely low tendency to leaching, can be disposed off as a... 

Miscellaneous hazardous materials in DOT/UN Class 9 are defined as a material which presents a hazard during transportation, but which does not meet the definition of any other hazard class. Other hazards might include anesthetic, noxious (harmful to health), elevated temperature, hazardous substance, hazardous waste, or marine pollutant. They may be encountered as solids of varying configurations, gases, and liquids. Examples include asbestos, dry ice, molten sulfur, and lithium batteries. These materials would be labeled and placarded with the Class 9 Miscellaneous Hazardous Materials placard, which is white with seven vertical black stripes on the top half. 

Remediation. Many companies specialize in hazardous-waste remediation by providing a variety of disposal services and equipment, not limited to catalytic oxidizers and carbon adsorption systems. Remediation includes reduction and cleanup of hazardous wastewater by using oil-water separators to separate oil and solids from wastewater effluents of petroleum-based industries. Other hazardous-vwiste remediation services include demolition and removal of hazardous materials such as asbestos, removal of leaky fuel tanks, cleanup of contaminated sods, and the construction of slurry walls to aid in the remediation of groundwater that is polluted with hazardous waste. Bioremediation is also a growing field that involves disposal of medical and laboratory wastes often by using microorganisms to break down the hazardous materials.
