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

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.

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

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.

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 :

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]
