Our previous work [1] resulted in a new bottle-to-bottle process that employs dry air atmosphere under ideal mass and heat transfer conditions to remove contaminants from polymer matrix. The experimental results showed that dry air was able to increase the productivity of PET super-clean technologies, based on solid-state polymerization processes (SSP). In this work we have evaluated the difference in desorption rate of model contaminants from recycled PET in dry air and nitrogen atmosphere by thermogravimetric analysis. Furthermore, it was investigated if sample exposed to synthetic air and nitrogen atmosphere during the thermogravimetric analysis presented any difference in their thermal properties. According to the results obtained in this work, the thermogravimetric analysis was not sensitive to detect difference in the rate of contaminant desorption from PET in synthetic air and in nitrogen atmosphere and any evidence of interaction between PET matrix and exposed atmosphere has not been observed by DSC analysis.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88695432","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}

These will include issues related to diminishing supplies and increased costs of fossil fuels, the demands for a reduction in the emissions of greenhouse gases, an increasing requirement for distributed generation and its integration into the grid system; and an increased demand for “digital quality power”. Digital devices are highly sensitive to the slightest fluctuations in power supplies, and it is expected that 30% or more of the demand in 2025 will be for power capable of meeting this requirement. Nanotechnology offers possible solutions to these challenges; and some of these are discussed here. While some of these developments are evolutionary in character, based on the improvement of technologies that are currently in research and early development, the magnitude of the problems suggest a need for what have been called “disruptive technologies” and these are also discussed here.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82359791","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}
