I just want to say one word to you —just one word— ‘plastics.’ Advice to Dustin Hoffman’s character in The Graduate

What are plastics? Materials composed of large molecules (called polymers) which are synthetically made or modified –Most are made from oil

What are plastics used for? Work with your neighbor and try to identify as many plastic products in this room as you can in the next 60 seconds

Automobile –Weight (mileage) Aviation –767, 787 –Voyager, Space Ship One Everywhere What are plastics used for?

Range of Products (defined by government’s NAICS* codes) Plastics Bags Plastic Packaging Film and Sheet Non-packaging Film and Sheet Plastics Profile Shapes Plastics Pipe & Pipe Fittings Laminated Plate, Sheet and Shape Polystyrene Foam Products Urethane and Other Foam Products Plastic Bottles Plastic Plumbing Fixtures Resilient Floor Covering Plastics Products, Not Classified Elsewhere (Source: Probe Economics, Inc. 2004) * North American Industry Classification System

Plastics products improve our daily lives and have made vast improvements in areas such as: Medicine - helping us all live longer, healthier lives Electronics - information, communication, and entertainment Building and Construction - durability, aesthetics, and high performance Transportation - Automotive, Aerospace, and Space Exploration Personal protection - children, athletes, police, and firefighters Innovative packaging - freshness, storage stability, and protection from bacteria Recyclability and reuse (SPI* created the international recycling symbols/numbers to facilitate recycling) Plastics * Society of the Plastics Industry

They are inexpensive to produce, and easy to mold, cast, or machine Their properties can be expanded even further in composites with other materials Plastics

Benefits of Plastics Case Study: Transportation  During the oil crisis in the 70’s, automakers found that plastics made cars more energy efficient by reducing weight  Plastics began finding their way into automobile components (bumpers, fenders, doors, etc.)  Plastics were also used for their  Durability  Corrosion Resistance  Toughness  Resiliency  Lightweight

Benefits of Plastics Transportation cont…  Plastics reduced the weight of the average passenger car built in 1988 by 145 pounds  That saves millions of gallons of gas each year and will save the energy equivalent of 21 million barrels of oil over the average lifetime of those cars

Plastics is a complex industry  Processors – (four main processing methods)  Injection Molding  Extrusion  Blow Molding  Thermoforming  Equipment Suppliers  Raw Material Suppliers

Comparison with Other Industries in the United States Plastics industry is the nation’s 4 th largest manufacturing industry (shipments) : 1. Motor Vehicles and Equipment 2. Petroleum Refining 3. Electronic Components and Accessories 4. Plastics (Source: Probe Economics, Inc. 2004)

Environmental Issues

Source Reduction Replacing bulky/heavy products with properly engineered, lighter, lower volume per part products “In a comparison of the two types of grocery bags, Franklin Associates concluded that the manufacture of plastic bags produced considerably less air pollution, water borne wastes, and industrial solid-waste than the manufacture of paper. Because plastic bags are lighter, they also produce less post-consumer solid waste, taking up less space in landfills. Researchers found that plastic sacks have these advantages even when grocery store clerks pack less in each bag, thereby using 1.5 or 2 times as many plastic bags to pack the same groceries as paper.” Brower, Michael & Leon, Warren (1999) The Consumer's Guide to Effective Environmental Choices - Practical Advice from the Union of Concerned Scientists, Three Rivers Press, New York, p

Future Rational analysis of each product type and its own particular use Be open to suggestions from environmental lobbyists Put aside emotional issues in favor of reasoned positions based on scientific principles

Critical Thinking— Recognizing Fallacies A fallacy is a deceptive argument; its conclusion is not well supported by its premises.

Appeal to Popularity Ford makes the best automobile in America; after all, more people drive Fords than any other American car.

False Cause I placed the quartz crystal on my forehead, and in five minutes my headache was gone. The crystal made my headache go away.

Appeal to Emotion In a commercial for Michelin tires, a picture of a baby is shown with the words “because so much is riding on your tires.”

Environmental Project

There is a current debate regarding the use of plastic versus paper products and their effects on the environment. For this report, you will need to research the issues on both sides of this debate and prepare a written report of 5-6 pages in which you discuss the pros and cons of both paper and plastic products.
