Sustainability :Sustainability Humanity has the ability to make development sustainable - to ensure that it meets the needs of the present without compromising the ability of future generations to meet their own needs.
World Commission on Environment and Development, 1987
World Summit onSustainable Development :World Summit onSustainable Development Earth Summit 2002: Aug. 26 – Sept. 6, 2002
191 countries represented
Developed plan to alleviate poverty and conserve natural resources
World Summit on Sustainable Development - Water :World Summit on Sustainable Development - Water Aim is to halve the number of people in the world without clean water and basic sanitation by 2015 (1.1 billion people)
World Summit on Sustainable Development – Renewable Energy :World Summit on Sustainable Development – Renewable Energy Sets goal of “substantially increasing” global share of renewable energy sources
Unfortunately, no targets or timetables set
Worldwide Commercial Energy Consumption :Worldwide Commercial Energy Consumption World Resources Institute, 1992
World Summit on Sustainable Development – Global Warming :World Summit on Sustainable Development – Global Warming Kyoto Protocol on climate change is assured of entry into force with its ratification by Canada, Russia and China, but the U.S. still refuses to sign

Slide 13:“We have learned the inherent limitations of treating and
burning wastes. A problem solved in one part of the
environment may become a new problem in another part.
We must curtail pollution closer to its origin so that it is
not transferred from place to place.” William Reilly
former U.S. EPA Administrator
1990
Zero Pollution is a Goal, But Usually Never Totally Achievable :Zero Pollution is a Goal, But Usually Never Totally Achievable
What is Pollution Prevention? :What is Pollution Prevention? Reducing or eliminating toxic materials
replacing a material in the production line
reformulating the product
installing new or modifying existing process equipment
Closed loop (on-site) recycling
Should involve a holistic approach
Slide 16:A waste is a resource out of place.
P2 Hierarchy :P2 Hierarchy
Process Development And Design :Process Development And Design Refinement of a process concept from early conceptual stages through preliminary engineering
Waste generation can often be minimized through proper design and operation of the process system
Typical Environmental Design Constraints and Objectives :Typical Environmental Design Constraints and Objectives
LCA :LCA Life-cycle analysis (LCA) is a sophisticated way of examining the total environmental impact of a product through every step of its life -- from obtaining raw materials all the way through making it in a factory, selling it in a store, using it in the home, and disposing of it.
What is LCA? :What is LCA? Life Cycle Assessment (LCA) is a technique for assessing the potential environmental aspects associated with a product (or service), by:
compiling an inventory of relevant inputs and outputs,
evaluating the potential environmental impacts associated with those inputs and outputs,
interpreting the results of the inventory and impact phases in relation to the objectives of the study.
Product Life Cycle :Product Life Cycle
LCA and the Regulatory Process :LCA and the Regulatory Process LCA is voluntary in the U.S. At present
its use is limited, but expanding
LCA is mandatory in some European countries
used as the basis of packaging recovery and recycling targets
Benefits Of LCA :Benefits Of LCA companies can claim one product is better than another on the basis of LCA
LCA inventory process helps to narrow in on the area where the biggest reductions in environmental emissions can be made
can be used to reduce production costs

Basis of Pollution Prevention Planning :Basis of Pollution Prevention Planning requires a detailed understanding of how a company does business and how it makes its products
the plan should provide a mechanism for comprehensive and continuous review of company’s activities as they pertain to environmental issues
Major Elements of aPollution Prevention Plan :Major Elements of aPollution Prevention Plan building support for the plan throughout the company
organizing the program
setting goals and objectives
performing a preliminary assessment of P2 opportunities
identifying potential problems and solutions
Environmental Management Systems :Environmental Management Systems P2 planning procedures are now unified into a comprehensive system for managing environmental impacts by industry
ISO 14000 standards establish benchmarks for environmental management performance, and describe the measures that must be taken by industry to conform to these standards
ISO 14000 EMS Model Principles :ISO 14000 EMS Model Principles ISO 14000:
Commitment and Environmental Policy
Environmental Management Plan
Implementation
Measurement and Evaluation
Continual Review and Improvement
Green Design :Green Design term coined by Office of Technology Assessment
signifies a design process in which environmental attributes of a product are treated as design opportunities, rather than design constraints
incorporates environmental objectives with minimum loss to product, useful life or functionality
Dual Goals of Green Design :Dual Goals of Green Design
Old Design Philosophy :Old Design Philosophy “The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.”
Design for Environment (DfE) :Design for Environment (DfE) A practice by which environment considerations are integrated into product and process engineering design procedures
(Allenby, 1991)
Product Design :Product Design
Green Chemistry :Green Chemistry synthesis, processing and use of chemicals that reduces risks to human health and the environment
synthetic chemistry designed to use and generate fewer hazardous substances
aims at reducing the use of endangered resources by switching to more plentiful or renewable resources
Design for Disassembly :Design for Disassembly Facilitates the separation of components and materials from used products to encourage recycling and reuse.
Uses a cyclical approach to production as opposed to the current linear system.
Addresses the end disposal of a product as an opportunity to reuse materials.
Hierarchy of Recycling Options :Hierarchy of Recycling Options
Ways to Minimize Packaging :Ways to Minimize Packaging Reduce packaging
eliminate packaging by distributing the products unpackaged
use reusable packaging
modify product so it requires less packaging
reduce amount of packaging used
Material substitution
used recycled and recyclable materials
use degradable materials

Sustainable Development :Sustainable Development Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs
Conclusion :Conclusion “If we fail to convert our self-destructing economy into one that is environmentally sustainable, future generations will be overwhelmed by environmental degradation and social disintegration. Simple stated, if our generation does not turn things around, our children may not have the option of doing so.” L.R. Brown, 1993
Slide 42:“It took Britain half the resources of the planet
to achieve its prosperity; how many planets
will a country like India require....?” Mahatma Gandhi
[when asked if, after independence, India would attain British standards of living]
