1 Solid & Hazardous Wastes

2 Sustainable Resource Use?
Overarching principles of a low-throughput economy and society? Please describe three:

3 Industrial Ecology Principles on “cleaner production”
“Waste” redefined “Waste unplugged” “Waste plugged back in”

4 Material Flow Economies
Contrasted with Service Flow Economies

5 Cradle ? Cradle to Grave: Cradle to Cradle

6

7 Solid Waste Sources 1. Mining 2. Ag. 3. Manufacturing
4. MSW & Sewage Sludge/Biosolids

8 The fate of “Trash” (U.S.)
About half of it  Landfilled (perhaps with a small but growing portion of that going to landfillharmonic applications and the like) ~ 30% is recycled ~16% is incinerated

9 Fundamental Features of a

10 Sanitary Landfills Site Considerations: -Describe four-

11 Landfill Site Selection
Location ? Please elaborate, - perhaps stating the obvious Water table: what this refers to and why it might be of interest here Often related to WT  Precipitation  Leachate formation and MOVEMENT  (Leaking Liners …?)  Groundwater Contamination ??

12 … The Daily Cover …

13 Just Add Water ….. Why?

14 What’s Up with the Bird?

15

16 Waste = Food ? For many Feathered Friends …

17

18 Puente Hills Landfill

19 Primary & Secondary Recycling
Primary: Closed Loop Secondary: Open Loop

20 Pre- vs. Post- Consumer Waste: ? Why does it matter ?

21 Potential Obstacles to Recycling
Describe twelve: (Three would be fine here)

22 Market-price for Recycled Materials
NIMBY mind-set Costs to Operate: Facilities, vehicles/transportation networks, fuel/energy to convert, Scale ? others ………..

23 Materials Recovery Facilities
Advantages & Potential Disadvantages

24 Waste-to-Energy Plants: PROs / CONs

25 “Hazardous” legally defined:
carcinogenic, mutagenic, teratogenic, easily flammable, explosive, volatile, corrosive

26 Managing Hazardous Wastes
Describe three accepted methods:

27 Surface Impoundments: “Pool”
Deep Well Injection: “TerraSyringe” Above Ground , or In-ground storage repositories: “Vault”

28 Remediation Bioremediation: Phytoremediation:

29 Bioremediation Bacterium Deinococcus radiodurans:
genetically engineered to absorb Toluene and elemental Mercury Fungi (Mycoremediation): Oyster Fungi absorbs PAHs (polycyclic aromatic hydrocarbons), such as benzo alpha pyrene (the “first carcinogen”, chimney sweeps carcinoma, 1700s)

30 Phytoremediation Phytostabilization: Phytodegradation: Phytoextraction:

31 Potential Haz. Mat(s). Examples
Please be familiar with a brief description & major source of each: Pb, Dioxins, Chlorine, Methane, PCBs, MTBE, Leachate, Plastics (incl. nurdles), Hydrogen Sulfide, DDT, …

32 Brownfields: Please share a brief description and one example

33 Law & Order Prominent legislation: -RCRA: provisons C-2-G -CERCLA:
Superfund

34 RCRA stands for:

35

36

37 Superfund: CERCLA highlight please note the “d” in Superfund
Abandoned, hazardous waste sites To be based on a Polluter-Pays Principle, … but,

38 Superfund Sites are much higher risk and much more extensively impacted sites than Brownfields

39 Pay-As-You-Throw: Potential Challenges ?

40 Majora Carter: Environmental & Social Justice Leader
South Bronx vs. Manhattan: where are the historically polluting Industries?

41 Lois Gibbs and Love Canal

42 Van Jones: The Green Collar Economy
Jobs, Justice, Policy, Environmental Integrity, sustainability

43 Anne Anderson & Woburn, MA.
The story, the book, the movie,

44 HAAs Hormonally Active Agents: cause developmental / reproductive abnormalities Ex: Atrazine, PCBs, Phthalates, Bisphenol A(BPA), DDT

45 Brief Summary of Ch. 15 Toxicology Concepts
1. LD 50 2. Chronic & Acute 3. Teratogens 4. Variables influencing Substance Impact(s) 5. Ecological Gradient 6. Case Studies

46 UGA w/ the PPTing For Now
