Hazardous Waste Management
Eco Safetech Hazardous waste management procedure involves reducing the number of hazardous substances produced, to treat hazardous wastes to reduce their toxicity, and to apply sound engineering controls to reduce or eliminate exposures to these wastes. Hazardous wastes can take the form of solids, liquids, sludges, or contained gases, and they are generated primarily by chemical production, manufacturing, and other industrial activities. They may cause damage during inadequate storage, transportation, treatment, or disposal operations. Hazardous wastes that are disposed of causes potential hazard to human health or the environment (soil, air, and water) when it is not properly managed. They are non-biodegradable, persistent in the environment and are deleterious to human health or natural resources. he four characteristics of hazardous waste are: ignitability • corrosivity • reactivity • toxicity. The regulations explaining these characteristics and the test methods to be used in detecting their presence are found in Part 261, Subpart C.
Ignitable Wastes
A flammable solid liquid and has a flash point below 140 degrees Fahrenheit, an ignitable compressed gas and classified by the U.S. Department of Transportation as an oxidizer.
Corrosive Wastes
A waste which is aqueous (i.e., water-based) and has a pH of 2.0 or lower (i.e., a strong acid) or 12.5 or more or it can corrode steel at a rate of greater than ¼ inch per year.
Reactive Wastes
Reactive wastes include wastes that are unstable, react with water or form hazardous mixtures with water, are capable of releasing toxic gases under certain conditions.
Toxic Wastes
Toxic waste contains any of 40 hazardous constituents includes 8 metals, 6 pesticides, 2 herbicides, 10 volatile organic compounds, and 14 semi-volatile organic compounds.
F-Listed Wastes
This list of wastes includes 28 different wastes, including certain spent solvents, metal finishing wastes, dioxin-containing wastes, chemical manufacturing wastes, wood preserving wastes, petroleum manufacturing wastes, and hazardous waste landfill leachate.
K-Listed Wastes
This list of wastes includes over 100 wastes from specific industrial processes. The specific processes are in the industries of wood preserving, petroleum refining, primary and secondary metals manufacturing, and the manufacturing of industrial chemicals, inks, pigments, pesticides, explosives, and veterinary pharmaceuticals.
Disposal of Hazardous Waste
