Sustainability Across the Curriculum Dr. Kauser Jahan, P.E. Dr. Beena Sukumaran Civil and Environmental Engineering
Introduction The USEPA has developed nine green engineering principles which engineers should follow to fully implement green engineering solutions: Engineer processes and products holistically, use systems analysis, and integrate environmental impact assessment tools. Conserve and improve natural ecosystems while protecting human health and well-being. Use life cycle thinking in all engineering activities. Ensure that all material and energy inputs and outputs are as inherently safe and benign as possible. Minimize depletion of natural resources. Strive to prevent waste. Develop and apply engineering solutions, while being cognizant of local geography, aspirations and cultures. Create engineering solutions beyond current or dominant technologies; improve, innovate and invent (technologies) to achieve sustainability. Actively engage communities and stakeholders in development of engineering solutions.
To allow the students to develop an understanding of the need to go green The website aims to show prospective and current students about the global, environmental issues that engineers encounter daily. The website will act as both a portal and as an informative webpage. Regarding the portal aspect of the website, the homepage will provide valuable links to direct students to other useful websites where they can learn and immerse themselves in the environmental aspect of engineering. The website will function as an informational website, and provide descriptions of how each class here at our CEE program at Rowan University will strive to incorporate environmental issues into the students curriculum. Objectives
Rowan University The comprehensive state university of Southern New Jersey. Located in Glassboro, NJ. Founded in 1923. University renamed in honor of Henry Rowan after $100 million gift in 1992 to create the College of Engineering. Rowan University consists of seven colleges –Business –Communication –Education –Engineering –Fine and Performing Arts –Liberal Arts and Sciences –Graduate and Continuing Education Who we are...
The Engineering Clinic Freshman Clinic I: Engineering Measurements Freshman Clinic II: Reverse Engineering Sophomore Clinic I: Alternate Fuel Sophomore Clinic II: Sustainability Junior Clinic: Multidisciplinary Design Project (semester) Senior Clinic: Multidisciplinary Design Project (year) Objectives: Design, Build and Test Hybrid Rocket Motor NASA G Boiling Expt. Aquarium Project Automated Crash Notification System C o m p le xi t y
The SanDestin Declaration of Green Engineering Principles (2003) Transforms existing practices to promote sustainability. Economically viable products, processes, and systems that – promote human welfare – while protecting human health – and elevating the protection of the biosphere New criterion for engineering solutions. What is Green Engineering?
Pollution Prevention Design for Environment Lean Manufacturing Clean Technology Ecological Engineering Molecules Industrial Parks Manufacturing plants Process units Earth Communities Industrial Ecology Sustainable Development Microscale Mesoscale Macroscale Megascale Global Green Engineering Green Chemistry
Freshman Engineering Clinic I Introduction to Engineering 2 sections taught by Civil faculty to all majors – Power/Efficiency Concepts Motor/turbine lifts weight – Alternative/Clean Energy Chemical Battery Hydro Solar Wind
Sophomore Clinic II Sustainability Greenhouse Gas Action Plan Rowan University has pledged to reduce greenhouse gas emissions to 3.5% below 1990 levels by 2011.
CAMPUS Project Goals Calculate GHG emissions for the university from 1990 to present based on electricity, natural gas, and oil consumption Perform an environmental audit of one aspect of the universitys operations Perform a life cycle inventory analysis Develop a plan for improving sustainable practices based on audit Perform an economic analysis: report costs or savings
Campus Recycling Areas of investigation: –Academic buildings –Residential buildings –Waste tonnage reports from waste handler Transportation Audit Campus Building Audit Water Use Alternative Energy Options Environmental Purchasing Green Dining (composting food waste) LEED Certified Buildings
Junior and Senior Clinics Arsenic Removal in Drinking Water BugPower: Fueling our Future with Microorganisms Metal Removal from Industrial Wastewater Developing "Green" Controlled Release Systems for Drug Delivery Use of Jute in Strengthening Asphalt Mixtures Stormwater Management in Chestnut Branch Watershed Environmentally Conscious Disassembly of End-of-Life Computers Chemical Kinetic Model Development and Flow Reactor Studies of Biodiesel Fuel Blends Long-Life Smart Structures for Laser Data Transmission Invertebrates as Bio-indicators of the Water Quality of the Maurice River Design of Detoxifying Systems for Organo-nitriles Mediated by Cyanogenic Enzymes
Energy Audits Ft.

Integration of Green Engineering in the Chemical Engineering Curriculum
Electrical and Mechanical Engineering Incorporated into Traditional Coursework: ECE: Networks Course: Efficiency of Electric Power Production and Environmental Impacts – <35% efficiency, Air pollution generated (CO 2, SO x, NO x, TSP) Electronics Course: Semester Paper Focuses on the Environmental Impacts of the Semiconductor Industry Sustainable Design elective ME: Address Design for Environment, Green materials and processes as part of Design Courses
Homepage with links to various Rowan University web pages, engineering websites, along with links to informative websites such as one to calculate your carbon footprint. A web page that displays all of the Civil Engineering core classes along with the display of the green employee and student of the month. These individuals display characteristics that aim to protect and redevelop the environment in both public and private settings. Each core class displayed has a link that shows what the classs curriculum is along with how the class is striving to bring more environmental issues into the classroom.
