What is solid waste and its types?
RCRA states that “solid waste” means any garbage or refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded material, resulting from industrial, commercial, mining, and agricultural operations, and from community activities..
What are the 3 categories of hazardous waste?
The EPA defines three types of hazardous waste: listed, characteristic, and mixed radiological waste. Each of these categories has subcategories that can become very precise, but the basics are as follows.
What is a hazard?
A hazard is a source or a situation with the potential for harm in terms of human injury or ill-health, damage to property, damage to the environment, or a combination of these.
What are the main sources of hazardous waste?
Some major sources are agricultural land and agroindusty, households, mines and mineral processing sites, health care facilities, commercial facilities, institutional facilities, industrial sites, solid waste disposal sites, contaminated sites and building materials.
What are the 4 types of hazardous waste?
When categorizing hazardous waste, the EPA breaks it down by four characteristics:ignitability, or something flammable.corrosivity, or something that can rust or decompose.reactivity, or something explosive.toxicity, or something poisonous.
What are the effects of solid waste?
The Effects of Solid Waste DisposalLand Use. The size of some landfills is nearly inconceivable. … Toxins. Many types of objects that are thrown away contain toxic substances that can leach into soil and water, affecting the health of plants, animals and humans. … Methane. When trash and garbage are put into an enormous pile, they begin to rot. … Smell. … Oceans.
What are the two sources of hazardous waste?
Sources of hazardous wastes include industries, petroleum refineries, transportation, coke-ovens, blast furnace sludges, scrubbing sludges and biological waste generating laboratories, thermal and nuclear power plants and nuclear reactors etc.
What are the 7 categories of hazardous waste?
They can be divided into seven groups depending on the type of manufacturing or industrial operation that creates them:Spent solvent wastes,Electroplating and other metal finishing wastes,Dioxin-bearing wastes,Chlorinated aliphatic hydrocarbons production,Wood preserving wastes,More items…•
What are the examples of hazardous waste?
Examples of household hazardous waste include:Solvent-based paints.Pesticides and other garden chemicals.Batteries (for example car, mobile phone or regular household batteries)Motor oils (for example from cars or mowers)Petrol and kerosene.Cleaning and polishing chemicals.Swimming pool or spa bath chemicals.More items…•
How is hazardous waste treated?
Treatment – Using various processes, such as incineration or oxidation, to alter the character or composition of hazardous wastes. Some treatment processes enable waste to be recovered and reused in manufacturing settings, while other treatment processes dramatically reduce the amount of hazardous waste.
What is hazardous waste classification?
Hazardous wastes are classified on the basis of their biological, chemical, and physical properties. These properties generate materials that are either toxic, reactive, ignitable, corrosive, infectious, or radioactive. Toxic wastes are poisons, even in very small or trace amounts.
What are the 4 types of waste?
Sources of waste can be broadly classified into four types: Industrial, Commercial, Domestic, and Agricultural.Industrial Waste. These are the wastes created in factories and industries. … Commercial Waste. Commercial wastes are produced in schools, colleges, shops, and offices. … Domestic Waste. … Agricultural Waste.
How do you deal with solid and hazardous waste?
Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.
What is the most hazardous waste?
The most dangerous hazardous waste is the waste created by nuclear power plants and nuclear weapons facilities. Although industry creates a large amount of hazardous waste in the United States and other industrial countries, this waste is highly regulated and controlled.
Why it is called hazardous waste?
A hazardous waste is a special type of waste because it cannot be disposed of by common means like other by-products of our everyday lives. Depending on the physical state of the waste, treatment and solidification processes might be required.
