1. ENVIRONMENTAL ENGINEERING APPLICATIONS: Solid & Hazardous Wastes

2. Topics covered: Solid waste - amounts generated, disposal options, status of recycling; Hazardous wastes types of wastes environmental media treatment options site remediation - Gierke Pollution prevention - Crittenden

3. Waste generation: U.S. 4.3 lb per person per day municipal plus 6 lb/person-day industrial = 1.9 ton/person-year 664 million tons/year = 0.12 mi 3 = 21,560 blocks the size of CSE Bldg = 0.05 mm/yr across U.S. or 3.8 mm/generation Why is this a problem? Space (tipping fees in U.S.: $20-$200/ton Loss of resources Groundwater contamination

7. MTU WASTE COMPOSITION

9. Environmental Engineers’ Role: Minimize personal waste; Reduce, Reuse, Recycle; Pollution Prevention - prevent refuse generation; Design recycling systems; Design waste-to-energy systems; Design, manage landfills, municipal disposal systems;

10. http://www.epa.gov/tri/ http://www.scorecard.org/ Toxic and hazardous substances What are they? ~650 individual chemicals and classes of chemicals Radionuclides, persistent organic pollutants, endocrine disruptors, biocides, metals, acids,... Where are they? In all environmental media (air, soil, surface & ground water) Where can you locate information on these substances? EPA’s Toxic Release Inventory -

11. Where do they come from?

12. Where are they discharged?

13. Are they near me?

14. What do environmental engineers do about toxic & hazardous substances? 1. Design methods for clean-up and remediation; John Gierke - Air sparging for treatment of contaminated groundwater; Alex Mayer - Modeling of pump-and-treat remediation of contaminated groundwater; John Crittenden, Dave Hand - design of photocatalysts to destroy groundwater contaminants;

17. What do environmental engineers do about toxic & hazardous substances? 2. Study their fate and effects in the environment; Judith Perlinger - study rates of natural attenuation of toxic compounds in groundwater; Jim Mihelcic - study rates of biological transformation (breakdown) of toxic contaminants;
