  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 mi3 = 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

  4. MTU WASTE COMPOSITION

  5. 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;

  6. 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 - http://www.epa.gov/tri/ http://www.scorecard.org/

  7. Where do they come from?

  8. Where are they discharged?

  9. Are they near me?

  10. 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;

  11. 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;

  12. Visualization with Computational Chemistry Bromoform Chloroform 1,1,1-trichlorotrifluoroethane Perchloroethene

  13. LFER for Iron Porphyrin System log(k, pred) = - 0.0777 (±0.0105) DR-X - 0.00804 (±0.00961) Go’ + 21.7 (±2.82)

  14. Where will you learn about toxic & hazardous substances at MTU? GE3850 Geohydrology CE4501 Environmental Chemistry CE4506 Applications of Environmental Regulations CE4505 Surface Water Quality Engineering CE5503 Physical-chemical Treatment Processes CE5507 Biological Remediation Processes CE5509 Environmental Organic Chemistry
