What is Hazardous Waste????

Hazardous Waste as defined in the Rules

Any waste which by reason of any of its physical,

chemical, reactive, toxic, flammable, explosive or

corrosive characteristics causes danger or is likely to

cause danger to health or environment, whether alone

or when in contact with other wastes or substances.

Categories of Hazardous Waste

Hazardous waste determinations are based upon whether the material is a :

Characteristic Waste (Listed on the D-list or TCLP) A listed waste ( materials specifically identified on

one of the following lists: F, K, U or P lists) Universal waste (batteries; lamps; pesticides; mercury

from thermometers)

Characteristic WastesAny waste which exhibit any characterstics from the

following characterstics considered as characteristics' waste

• Ignitablity (flashpoint is less than 1400 F) includes oxidizers…

• Corrosivity (pH less than or equal to • 2 or greater than or equal to 12.5)

• Reactivity (water reactives, normally unstable materials, cyanides &

sulfides…).

Listed WastesF-listed wastes are from non-specific sourcesK-listed wastes are from specific sourcesU-listed wastes are toxic wastesP-listed wastes are acutely hazardous wastes

Examples of U & P-Listed Wastes U LISTED WASTE P LISTED WASTE

Acetaldehyde Allyl alcohol

Acetone Ammonium vanadate

Acetonitrile Arsenic acid

Aniline Arsenic trioxide

Benzene Carbon disulfide

Bromoform 2,4-Dinitrophenol

1-Butanol Fluorine

Chloroform Nitric oxide

Universal Wastes Universal wastes include the following materials that

are commonly found in the workplace Batteries Fluorescent lamps Pesticides Thermometers (containing mercury)

HAZARDOUS WASTE GENERATION

EFFECT OF H.W ON HUMAN HEALTH

Humans, plants, and animals can be exposed to hazardous substances through -

Inhalation Ingestion Dermal exposure

Useful methods of Hazardous Waste Management

Minimizing the quantity of waste

Recycling of industrial waste

Treatment of the waste

Collection, transport and disposal of waste in an

environmentally sound manner.

Waste Minimization

This proces is divided in three sub-parts that are –

Process Modification Waste Concentration Waste Segregation

Recycling Industrial Wastes

Waste Reuse Waste Recycling

Collection, Transport and Disposal of hazardous waste

Disposal of hazardous waste can be done in four ways-

Landfill disposal.CompostingDumping at sea

Advantages & Disadvantages of Landfill

Advantages Sanitary landfill No open burning, ultimate disposal Little odour Low water/groundwater pollution Can handle large amounts of wastes, less cost Filled land can be used for other purposes

Disadvantages Noise and traffic Air pollution from toxic gases and volatile organic compounds Releases greenhouse gases (methane and CO2) Can leak and cause groundwater contamination Slow decomposition of waste Encourages waste production

HAZARDOUS WASTE MANAGEMENT GUIDELINES

Guidelines for Occupier/Generator of Hazardous

Waste .

Guidelines for Transportation of Hazardous Waste .

Guidelines for Occupier/Generator of Hazardous Waste .

To keep the complete record of the types,quantities , characterstics of HW.

To transport the Hazardous waste through specified & registered transporters.

To full-fill the pre- transport requirement before transporting HW.

To dispose of HW only at notified disposal facilities.

Guidelines for Transportation of Hazardous Waste .

• To ensure that the occupier/generator transport their hazardous waste only in the specified transport vehicles.

• The transporters should be asked to train the drivers and helpers of hazardous waste transport vehicles to handle the wastes under emergency situations.
