Overview of Pollution Prevention and Resource Management Specialization at Bren School

The Pollution Prevention and Resource Management (PPR) specialization at Bren School focuses on the urgent need for efficient waste management in response to rising population and development. Key topics include emerging and legacy pollutants, resource conservation, and remediation strategies. The curriculum emphasizes life cycle analysis, prevention techniques, and industry sustainability. Notably, real-world case studies—such as the 2005 Benzene spill in the Songhua River—highlight critical questions on pollution impact and management strategies. Graduates pursue careers in various environmental sectors.

  1. PPR Specialization Overview 9-27-12 Prof. Trish Holden, Bren School

  2. Why PPR ? • Pollution • Waste management: driven by population and development • Emerging pollutants in U.S. , EU, etc. • Legacy pollutants globally (Hg, DDT, etc.) • Soil (agricultural sustainability), water: scarce resources • Prevention • “Greening” of industry / products • Analysis of life cycle (raw materials to end-of-life for products) • Resource conservation • By-product recovery • Remediation • Ex- vs. in-situ • Engineered vs. monitored natural attenuation (frog: http://www.greenchemistrynetwork.org/gcp.htm)

  3. Example problem • 2005 Benzene spill in Songhua River, PRC • Songhua River: drinking water source • Harbin (9 M people) • Other PRC cities • Russia: x-border city of 0.7 M people • Benzene • toxic carcinogen • somewhat soluble in water • volatile • can biodegrade

  4. Example: questions & concerns • How hazardous is this spill for humans and biota? • How far downstream will the pollution travel? • What are the pollutant fates? • What can we do about the pollution, and when? • How can we avoid this in the future?

  9. YOUR POS • individual POS • initial meeting w/ advisor to discuss background, and goals • follow-up, as desired • suggested classes (website ; example POS) • You may be well-versed already in some... • “Combo” may make sense w/ other specialization, for you • PPR and CEM • PPR and WRM..

  10. Group Projects: past examples • Nanomaterials industry EHS + product stewardship • Evaluation of bacteriological water quality in Las Palmas Creek • Analysis of food scrap recycling to reduce solid waste • Wetlandsmitigation: Casmaliawaste site • Ecological risk of MTBE plume • Goleta Oldtownbrownfields redevelopment • Bioswale management of storm runoff • Pharmaceuticalsin surface waters • Life cycle analysis of eco-sneakers

  11. Jobs: Sectors w/ PPR Grads(see Dave or Kristen for more info)

  12. Jobs: example titles • Project Manager • Environmental Scientist • Environmental Sustainability Analyst • Staff Engineer • Environmental Compliance Specialist • Environmental Protection Specialist
