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
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?
16
Waste = Food ? For many Feathered Friends …
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:
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
