6 Environmental Engineering Education: Traditional, Students analyzed model wastes in Lab Students made a lab report Some lab projects include compost, silage and wastewater treatment Lab reports Good technicians

Students made a lab report Some lab projects include

7 Academic project: manual lab reports vs. project proposals Objective: Develop team work, analysis/synthesis and problem solving skills Strategy: Half of the student teams traditional Lab sessions Half of the student teams- working with regional wastes Planning : One year in advance: reagents, materials, lab space Analysis of results: Analysis of projects by professor Student survey

Strategy: Half of the student teams traditional Lab sessions Half of the student teams- working

11 Proposal of Education : p Regional liquid and solid waste Lab analysis Bioprocess for Bi f treatment t t t or added value Proposal of solution

12 Challenge: Solving regional problems Silage losses by molds Make compost Improve the process 10 6 Tons/year of wheat straw Pellets No till Gassification

13 Challenge: Solving regional problems Carrot and vegetable waste Minimal processed products, dried products Carotenoids, capsaicinoids Arsenic, pathogens in water Municipal treatment Household treatment

14 New paradigm: problem solving Problematic situation Solid or liquid waste proposal lab field results

15 Opportunities: A place in the University farm to make projects with agricultural wastes A place in the industrial district to add value to wastes and 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 Challenges and opportunities: Interdisciplinary work (interdepartmental work) Collaborative work with other universities
