2. What is Hazardous Waste Ignitability Corosivity Reactivity Toxicity Ignitability Corosivity Reactivity Toxicity

3. Ignitable  Determined to be flammable under certain conditions

4. Corrosive  Corrodes metals or has a very high or low pH

5. Reactive  Readily explodes or undergoes violent reactions

6. Toxicity  Known to harmful or fatal when ingested and is known to leach into ground water

7. Examples of Hazardous Waste  Dyes, cleansers and solvents  PCBs used in insulating material, plastics, solvents, lubricants, and sealants  Toxic heavy metals--lead, mercury, cadmium, and zinc  Pesticides  Radioactive waste  Dyes, cleansers and solvents  PCBs used in insulating material, plastics, solvents, lubricants, and sealants  Toxic heavy metals--lead, mercury, cadmium, and zinc  Pesticides  Radioactive waste

8. Where do you create hazardous waste  School--laboratories, art classes  Dry cleaning--chemical process  Construction--painting & vehicle maintenance  Vehicle maintenance--rust removal, painting  Lawn maintenance--pesticides  School--laboratories, art classes  Dry cleaning--chemical process  Construction--painting & vehicle maintenance  Vehicle maintenance--rust removal, painting  Lawn maintenance--pesticides

9. Electronic Waste  Because of the large and expanding universe of electronic devices, we have discarded electronic devices, do you know where they go…

10. Electronic Waste

12. Excluded from Hazardous Waste Regulation  Domestic sewage  Some industrial waste discharge*  Radioactive waste*  Recycled used oil and filters  Some agricultural waste  Processed scrap metal *taken care of by other legislative bodies  Domestic sewage  Some industrial waste discharge*  Radioactive waste*  Recycled used oil and filters  Some agricultural waste  Processed scrap metal *taken care of by other legislative bodies

13. Hazardous waste recycling  Combustion for Energy Recovery- incinerating waste  Use Constituting Disposal-applying to land, asphalt,cement  Reclamation- return to original use after purification.  Resource conservation- ie batteries  Combustion for Energy Recovery- incinerating waste  Use Constituting Disposal-applying to land, asphalt,cement  Reclamation- return to original use after purification.  Resource conservation- ie batteries

14. How do we solve this problem  Waste minimization  substitute eco-friendly materials  Reduce amount of hazardous waste made  Waste minimization  substitute eco-friendly materials  Reduce amount of hazardous waste made

15. Where do Hazardous Wastes go  Made into cement--converting hazardous waste sludge to reduce the leach ability of contaminants.  Neutralization--adjusting the pH of some toxic materials to reduce the leaching ability of the waste  Incineration, destruction and waste-to- energy--different types of incinerators vary depending on the characteristics of the waste  Made into cement--converting hazardous waste sludge to reduce the leach ability of contaminants.  Neutralization--adjusting the pH of some toxic materials to reduce the leaching ability of the waste  Incineration, destruction and waste-to- energy--different types of incinerators vary depending on the characteristics of the waste

16. Where do Hazardous Wastes go  Hazardous waste landfill--A HW may be sequestered in a HW landfill or permanent disposal facility.

17. Pryolsis  Form of incineration  chemically decomposes organic materials by heat in the absence of oxygen  occurs under pressure and at temperatures above 430 o C (800 o F)  Form of incineration  chemically decomposes organic materials by heat in the absence of oxygen  occurs under pressure and at temperatures above 430 o C (800 o F)

18. What about Nuclear Waste  Integrated Used Fuel Management--used nuclear fuel remains stored at power plants that created it  Storage of used nuclear fuel-- the government plans to create advanced recycling technologies to reduce amounts and toxicity  Repository development--deep geologic repository in remote desert location,Yucca Mtn.  Transportation--used fuel will be sent to Yucca mountain via rail and roadways is special containers  Integrated Used Fuel Management--used nuclear fuel remains stored at power plants that created it  Storage of used nuclear fuel-- the government plans to create advanced recycling technologies to reduce amounts and toxicity  Repository development--deep geologic repository in remote desert location,Yucca Mtn.  Transportation--used fuel will be sent to Yucca mountain via rail and roadways is special containers Yucca Mountain Update and US Nuclear Storage
