The ESR was highly concentrated with electrical and electronic plastics. Three test conditions were investigated: 1) base case without additional electrical and electronic shredder residue; 2) addition of 11 weight percent ESR containing E&E plastics; 3) addition of 26 weight percent ESR with E&E plastics. The fact that some electrical and electronic equipment is already in the mixed MSW feed to many waste-to-energy plants made the testing important for the MHKW operator as well as for the local regulatory authorities (EPA). The tests investigated the effect of ESR on plant operations, air emissions (acids, organics, and metals), and ash characteristics, and on the destruction efficiencies for several chlorinated and brominated substances present in the ESR. The large scale test used 103 tons of ESR derived from 650 tons of a typical mix of information technology equipment, consumer electronics, small household appliances, and other products. The ESR was supplied by Electrocycling in Germany. The tests were successfully completed from an operational standpoint without long time delays and did not show any mechanical blockage during the test in spite of the high heating value, 23 GJ/t, of the ESR. The grate was operated at close to 90 percent throughput","PeriodicalId":141255,"journal":{"name":"Proceedings of the 2006 IEEE International Symposium on Electronics and the Environment, 2006.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126637724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The choice of injection molding machine type (hydraulic, hybrid or all-electric) has a substantial impact on the specific energy consumption (SEC). The SEC values for hydraulic, hybrid and all-electric machines analyzed are 19.0, 13.2 and 12.6 MJ/kg respectively (including auxiliaries, compounding and the inefficiency of the electric grid). For hydraulic and hybrid machines SEC seems to exhibit a decreasing behavior with increasing throughput. This derives from spreading fixed energy costs over more kilograms of polymer as throughput increases. For all-electric machines SEC is constant with throughput. When the polymer production stage is included in the analysis, the energy consumption values increase up to 100 MJ/kg. The overall injection molding energy consumption in the U.S. in a yearly basis amounts to 2.06 times 108 GJ. This value is of similar magnitude to the overall U.S. energy consumption for sand casting, and to the entire electricity production of some developed countries","PeriodicalId":141255,"journal":{"name":"Proceedings of the 2006 IEEE International Symposium on Electronics and the Environment, 2006.","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126671124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regulations, such as the European WEEE directive, and emissions trading are ways in which governments have changed the market paradigm, rewarding lower polluting manufacturers. With complex issues at stake within a production system, it becomes more difficult to measure the trade-offs between environmental benefit and economics. A modern approach in production theory of business and management economics enables this complex calculation by valuing everything in the system. This approach proposes that objects (e.g. materials) are defined as good, bad, or neutral. In transformation processes in production or recycling systems this makes it possible to distinguish stringently between the economic revenue of a process and the economic and ecological expenditures for it. Materials and energy classified as good are considered as an expense if they are used by the system and a product or revenue, if they are created by the system. This approach can be transferred to entire systems of processes in order to determine the system revenue and the system expenditure. The process can be more easily understood using material flow networks or graphs. In complex material flow systems, it becomes possible to calculate not only the costs, but also the direct and indirect environmental impacts of an individual process or system revenue (for example a product or the elimination of waste) consistently. The approach permits a stringent analysis as well as different analysis perspectives of a material and energy flow system. It is particularly suitable for closed-loop economic systems in which material backflows occur. This paper outlines how this approach can be employed in the field of e-waste management","PeriodicalId":141255,"journal":{"name":"Proceedings of the 2006 IEEE International Symposium on Electronics and the Environment, 2006.","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133225195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the United States and other areas of the world, much of this equipment is disposed in landfills. Research conducted at the University of Florida has been used by the United States environmental protection agency (EPA) and individual states as justification for rule- or policy-making for CRT management and recently work sponsored by the EPA was published that described the hazardous waste characteristics for other electronic devices. In both of these cases, devices that contained lead were often found to be toxicity characteristic hazardous wastes (unless otherwise exempted). But additional work found that the content of the device (e.g., amount of plastic vs steel) played a large role in whether lead leached at sufficient concentrations to be hazardous. States are considering the appropriate regulatory and policy initiatives that must be undertaken to address electronic equipment. Many electronic devices are exempt from regulation as a hazardous waste, as they are generated as a result of household activities. Local and state governments are thus faced with the need to determine whether additional measures should be implemented to collect and recycle these devices. Such programs demand funding which may be in short supply in communities wrestling with funding other recycling programs. Many communities find themselves having to answer is \"what is the true risk posed by the disposal of discarded electronic devices in landfills?\" A summary of the results of the prior research and new research from the simulated landfill experiments is presented. This information provides possible implications for state or regulatory rule making and information that will give electronic equipment manufacturers a better understanding of how to assess potential impacts of new products on the disposal system","PeriodicalId":141255,"journal":{"name":"Proceedings of the 2006 IEEE International Symposium on Electronics and the Environment, 2006.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131294570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Legal basis of differences in transposition is the article 175 of the Treaty, and its \"minimum requirement principle\". In several cases there are also varying influences of stakeholders involved in the transposition process or lack of overview of the practical consequences of such actions. The implementation process is currently leading to great differences amongst producers, governments, retailers, recyclers, compliances schemes and other involved. Beside the impact on producer's compliance cost, differences are also leading to more or less effectiveness in performances of national systems. One of the most important aspects here is the involvement of retailers in separate collection, by means of compensation of the collection and storage costs. It is observed as a key factor in those systems, running since years (Switzerland, Sweden and Norway have high collection amounts and an extended responsibility for retail 'all for all') or just set up (Ireland). Countries with a 1:1 mechanism for retail have moderate collection amounts and basically all other countries have none or lower collection performances maybe due to the fact that the retail sector is not willing to become active as collection points","PeriodicalId":141255,"journal":{"name":"Proceedings of the 2006 IEEE International Symposium on Electronics and the Environment, 2006.","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125522389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
