Corporate competitiveness traditionally has been achieved through new product development, quality performance, and cost control. Competitiveness in the twenty-first century will require extending these traditional elements to include the life-cycle environmental impacts of materials and final products. Three forces are driving this evolution. The forces driving life-cycle accountability are... [Pg.97]

The ability to obtain the materials of interest for the maintenance and extension of human society is perhaps one of the most important unsolved problems of the twenty-first century. As one looks around, it is obvious that very few chemicals used routinely in commercial operations are currently available from renewable sources. Occasionally we may find an example of a material that is from renewable sources, but these are usually accompanied by considerable life cycle environmental impacts. Or, we find that there are undesirable trade-offs between environmental impacts, such as a reduction in global warming potential, which at the same time significantly increases the eutrophication potentials associated with the material. A very relevant example of this sort of trade-off is seen in the production of bioethanol or biodiesel, where considerable controversy surrounds the sustainability of both of these fuels. [Pg.54]

If the total energy and emissions of a battery during its entire lifetime production, use, maintenance and disposal are established, then divided by the total lifetime energy of the battery, the total emissions per kilowatt-hour of energy may be derived. These are separated into specific materials, usually elements, compounds or groups of compounds, for which specific environmental and/or human health impact assessment values are available. Utilizing these values, the overall relative life cycle environmental impact of a particular battery system may be established and compared to other battery systems. As previously discussed, these analyses involve many assumptions and... [Pg.26]

In summary, the LCA studies show that, assuming current technological and energy use practices, PLA exhibits comparable nonrenewable energy use and greenhouse gas emissions to PE and PET [27, 38]. The life cycle environmental impacts of petro-polymers are often taken from the European Association of Plastics Manufacturers (APME). The APME has an extensive database of LCl data for numerous polymers, including PE, PET, PP, and PS. [Pg.434]

This paper presents an approach for identifying improved business and environmental performance of a process design. The design task is formulated as a multi-objective optimisation problem where consideration is given to not only the traditional economic criteria, but also to the multiple environmental concerns. Finally, using plant-wide substitution of alternative materials as an example, it is shown how potential step-change improvements in both life cycle environmental impact and process economics can be achieved. [Pg.683]

As biopolymers capture a larger market share, the measurement of their life cycle environmental impacts will be important to enable consumers and producers to identify more sustainable methods of use, production and disposal for such products. Life cycle assessment (LCA) is a tool that quantifies the environmental sustainability of biobased polymers from cradle to grave. ... [Pg.542]

A decision matrix was used to create two single value metrics for each polymer, one evaluating each polymer for life cycle environmental impacts and the other evaluating each polymer for adherence to green design principles. Results from both assessments were normalized to the average across aU polymers, shown in Eq. (15.3), where N- is the normalized value for polymer i in metric/impactj, V- is the... [Pg.545]

Figure 1S.4 Polymer assessments displayed in two dimensions, with adherence to green design principles on the x-axis and life cycle environmental impacts in the y-axis. In this system, greater values are more preferable, meaning greater adherence to principles, or normalized environmental impacts.
