•Northwest of México

•Yaqui Valley-- agriculture and small industrial activity

•A lot of solid residue from pig, cow and chicken farms

•Significant amount of vegetable waste: carrot, chili, tomatoSignificant amount of vegetable waste: carrot, chili, tomato

•Most of the wastewater do not receive treatment.

Environmental Engineering Education: Environmental Engineering Education: Traditional 2002Traditional 2002--20062006Traditional, 2002Traditional, 2002--20062006

•Students analyzed model wastes in Lab•Students made a lab report•Some lab projects include compost, silage and wastewater treatment

Lab reports Good technicians


Academic project: manual lab reports vs. project proposalsAcademic project: manual lab reports vs. project proposals

Strategy:

Objective: Develop team work, analysis/synthesisand problem solving skills

Strategy:•Half of the student teams—traditional Lab sessions•Half of the student teams- working with regional wastes

Planning 2007-2008:•One year in advance: reagents, materials, lab space

Analysis of results: Analysis of results: •Analysis of projects by professor •Student survey



Survey: eight questions with a 1-5 range of values to answer

1 LABORATORY FOUNDAMENTALS1 LABORATORY FOUNDAMENTALS2 PRACTICAL LAB SKILLS3 SCIENTIFIC KNOWLEDGE4 TECHNICAL PROBLEM SOLVING4 TECHNICAL PROBLEM SOLVING5 REGIONAL PROBLEM SOLVING6 WASTE TREATMENT DESIGN7 PROFESIONAL DEVELOPMENT7 PROFESIONAL DEVELOPMENT8 ENVIRONMENTAL AREA VOCATION



Result of survey



New skills developed: team working with regional wastes,team work, analysis/synthesis and problem solving skills

Opportunities:

•A place in the University farm to make projectswith agricultural wastes

•A place in the industrial district to add value to wastespand foods

•Management of a small town wastewater treatment plant (the plant was constructed in the land of our University)

Challenges:•Change of mental paradigms of local producers•Funding•Funding

Challenges and opportunities:•Interdisciplinary work (interdepartmental work)p y ( p )•Collaborative work with other universities
