Classification, Characterization & Identification of Hazardous Waste

Description of Hazardous waste and its concert identification according to EPA act/HWM Rule

1. Classification, Characterization & Identification of Hazardous Waste Presentation by Vinod Kumar Ph.D Scholar Guide: Dr. P. K. Singh Associate professor Department of Chemistry Babu Banarsi Das University, Lucknow Session 2017-18

2. Solid waste- vegetable waste, kitchen waste, household waste etc. E-waste- discarded electronic devices like computer, TV, music systems etc. Liquid waste- water used for different industries eg tanneries, distillaries , thermal power plants Plastic waste- plastic bags, bottles, buckets etc. Metal waste- unused metal sheet, metal scraps etc. Nuclear waste- unused materials from nuclear power plants Classification of Wastes

5. Waste characterization  ( waste characterization  US) is the process by which the composition of different  waste streams  is analyzed. Waste characterization plays an important part in any treatment of waste which may occur. Developers of new waste technologies must take into account what exactly waste streams consist of in order to fully treat the waste. The  biodegradable element  of the waste stream is vitally important in the use of systems such as  composting  or  anaerobic digestion . Why Need for Waste Characterization?

6. EPA Listed Hazardous Waste A specific list showing certain materials as hazardous wastes minimizes the need to test wastes as well as simplifies waste determination hazardous waste regulations apply to these lists of wastes. We will describe these wastes, classified in the F, K, P, and U industrial waste codes F - Listed :- Non specified source (Industrial process that may have generation the waste . (Ex – C 6 H 6 , C 6 H 6 OH, ). Solvent mixtures or blends, which contain greater than 10% of one or more of the solvents listed in F001, F002, F003, F004 and F005 are also considered F-listed wastes.

7. continue…. K – Listed :- Waste Generate from Specify industrial processes :- Ex. include wood preservation, pigment production, chemical production, petroleum refining, iron and steel production, explosive manufacturing and pesticide production. P - Listed :- Consist of discarded commercial chemical product off specification chemical, container residue and residue from spillage of material. U– Listed :- The U-List differ from P list by the quantity of which the chemical is regulated ; It include toxic waste such as:- a . Pesticides applicators. b . Laboratories. c. Chemical formulators

8. LISTING CRITERIA OF H/W 1. The waste typically contains harmful chemicals, and other factors indicate that it could pose a threat to human health and the environment in the absence of special regulation. Such wastes are known as toxic listed wastes. 2. The waste contains such dangerous chemicals that it could pose a threat to human health and the environment even when properly managed. Such wastes are known as acutely hazardous wastes. 3. The waste typically exhibits one of the four characteristics of hazardous waste described in the hazardous waste identification regulations (ignitability, corrosivity , reactivity, or toxicity). 4. When EPA has to cause to believe for some other reason, the waste typically fits within the statutory definition of hazardous waste developed by Congress

9. . Characteristics of Hazardous Waste Class C1: Ignitability , or something flammable Liquids with a flash point < 60⁰C i.e. alcohol, gasoline, and acetone Solids that spontaneously combust. Calorific value <2500 kcal/kg . Class C2: Corrosivity , that can rust or decompose Anything Hazardous Waste with a pH of less than or equal to 2.0 or greater than or equal to 12.5, or has the ability to corrode steel will be corrosive.

10. Class C3: Reactivity, or something explosive Unstable, and routinely experiences violent change without detonating Potential for explosive mixture or violent reaction when add water Toxic gasses are released when mixed with water Class C4: Toxicity , or something poisonous These contaminants (Heavy Metals and Pesticides )are identified solely through a test method called Toxicity Characteristic Leaching Procedure or TCLP.

11. continue…. Class C5: Substances or Wastes liable to spontaneous combustion - Substances or Wastes which are liable to spontaneous heating under normal conditions encountered in transport, or to heating up on contact with air, and being then liable to catch fire. Class C6: Substances or Wastes which, in contact with water emit flammable gases- Substances or Wastes which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities.

12. Class C7: Oxidizing- Substances or Wastes which, while in themselves not necessarily combustible , may, generally by yielding oxygen cause, or contribute to, the combustion of other materials. Class C8: Organic Peroxides - Organic substances or Wastes which contain the bivalent O−O Class C9: Poisons (acute) – Substances or Wastes liable either to cause death or serious injury Class C10: Infectious substances –Substances Wastes containing viable micro-organisms their toxins which are known or suspected to cause disease in animals or humans. Continue….

13. Class C11: Liberation of toxic gases in contact with air or water - Substances or Wastes which , by interaction with air or water, are liable to give off toxic gases in dangerous quantities. Class C12:Eco-toxic- Substances or Wastes which if released, present or may present immediate or delayed adverse impacts to the environment by means of bioaccumulation or toxic effects upon biotic systems or both. Class C13: Capable, by any means, after disposal, of yielding another material, e.g., leachate , which possesses any of the characteristics listed above . Continue….
