The environmental impact related to the use and production phases of the ICs could be potentially very strong due to the high technological level of the process, the amount of energy and the special materials used for their realization. The aim of this study is to evaluate the environmental impact of an IC during its production and use phases basing on the life cycle assessment (LCA) methodology. In fact the LCA is a useful tool to quantify the environmental impact. An EPROM IC has been chosen as a representative device for its technological complexity and its large diffusion in the market. Front-end and back-end technological steps have been analyzed in detail. The energy and the fixed consumables (gases, chemicals, ...,) used in the fab have been related to the number of masks. The number of the masking steps is an indicator of process complexity, The data inventory has been obtained from detailed technological analysis, from information obtained directly from material suppliers and from the commercial database. The IC process makes large use of de-ionized water (DI). The reclaim of DI water and other materials is important in order to reduce the total environmental impact. The total inventory for a single EPROM chip has been obtained. The same approach can be extended to other types of ICs.","PeriodicalId":448468,"journal":{"name":"Proceedings of the 2001 IEEE International Symposium on Electronics and the Environment. 2001 IEEE ISEE (Cat.

Remanufacturing, or recycling at a part level, involves the production-batch disassembly, restoration to like-new condition and reassembly of used products. Remanufacturing offers significant environmental benefits by retaining the energy, as well as material, embodied in the product during original manufacture, while diverting solid waste from landfills. Since the essential goal of remanufacture is to reuse parts, parts that are not reused enter the waste streams of remanufacturers and represent the ultimate obstacles to remanufacture. Study of these waste streams reveals insights about difficulties in remanufacture and how to avoid these difficulties through product design. Traditionally, remanufacturing has centered on products such as automotive parts and electrical motors, However, the growth in electronic and electrical product sectors has triggered a corresponding growth in the remanufacturing in these sectors. To support design for remanufacture in these sectors, waste streams of remanufacturers of different electronic products, namely laser-printer toner cartridges and telephones, were studied and quantified. This paper presents the results of these waste-stream analyses, including the identification of discard reasons, associated root causes for these discard reasons, and consequently, product design and other characteristics that are problematic for remanufacturing.","PeriodicalId":448468,"journal":{"name":"Proceedings of the 2001 IEEE International Symposium on Electronics and the Environment. 2001 IEEE ISEE (Cat.

The high purity requirements of input materials coupled with the extreme cleanliness of the processing environment provide a great challenge in managing the potential environmental impacts of this industry. High energy and water consumption and the throughput of hazardous auxiliaries give rise to additional environmental concerns. This paper presents a methodology for a life cycle inventory analysis (LCI) employed for a Motorola wafer fab. The LCI focuses on the generation of a complete data set of mass and energy flows for a wafer fab and the identification of environmentally significant aspects in wafer processing. Process modules within the infrastructure and the fab processes are identified as environmentally significant according to the consumption of energy, raw water, chemicals, gases and the origin of waste, wastewater, and emissions. The use of infrastructure facilities by fab processes is taken into account. The practical methodology worked out by Fraunhofer IZM and Motorola is a guideline to combine ecological and economical aspects and can be applied to realize environmental improvements within a company. The LCI data set is a basis for an impact assessment to gain LCA data for one of the most important processes in semiconductor fabrication. Corresponding methodologies for impact assessments are discussed.","PeriodicalId":448468,"journal":{"name":"Proceedings of the 2001 IEEE International Symposium on Electronics and the Environment. 2001 IEEE ISEE (Cat.

The removal of other plastics is essential if the properties are to approach those of virgin resin. Purification of plastic resins is achieved by exploiting differences in material properties of the different plastic types. Differences in density and surface properties have been shown to allow for the separation of a number of plastic materials. In many cases, streams of recycled plastic are composed of flakes of a wide variety of colors. The flakes can also range from clear to opaque. Separation of plastics into groups of similar colors can greatly increase their value because they can be colored to meet reasonable specifications much more easily. Sometimes, the different colors might correspond to different types of plastics, so their separation is desirable. For these reasons, the sorting of plastics based on color may prove to be a valuable separation technique for recycled plastic flakes. In this study undertaken jointly by the American Plastics Council and MBA Polymers, color sorting was applied to the separation of white, gray and black plastics from end-of-life electronic equipment. The composition dependence of sorting was investigated experimentally and compared with a theoretical model. Results indicate that increased levels of impurities decrease the throughput rate and result in increased impurity levels in both product and reject streams. The removal of black from a mixture of black and gray flakes was also demonstrated as a way to control product color.","PeriodicalId":448468,"journal":{"name":"Proceedings of the 2001 IEEE International Symposium on Electronics and the Environment. 2001 IEEE ISEE (Cat.
