Define total product life cycle, and describe the many stages at which pollutants may enter the environment
What will be an ideal response?
"Our use constitutes only one step in the total product life cycle, a term that encompasses all steps, from obtaining raw materials to final disposal of the product. Implicit in our use of hair spray, for example, is that raw materials were obtained and various chemicals were produced to make both the spray and its container. Chemical wastes and by-products are inevitable in production processes. In addition, consider the risk of accidents or spills occurring in the manufacturing process and in the transportation of raw materials, the finished product, or wastes. Finally, what are the risks of breathing hair spray? What happens to the container you throw into the trash, which still holds some of the hair spray when the propellant is used up?"
