Development of Chemical Recycling Process for Post- Consumer PET Bottles by Methanolysis in Supercritical Methanol

Post-consumer PET (polyethylene terephthalate) bottles have been recycled into fiber and sheet products ever since the Containers and Packing Recycling Law came into effect in 1997. There has been a growing need, however, for a chemical recycling process. In this process, post-consumer PET bottles are recycled into monomers that can be used as feed stocks for the recycled production of PET bott...

chemical recycling of polycarbonate waste using conventional heating and microwave assisted method

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...

Ocular injuries caused by metal caps of carbonated mineral water bottles.

BACKGROUND Bottles containing carbonated drinks are potentially hazardous to the eye. In this study, we aimed to document the clinical characteristics and visual outcomes in a series of patients with ocular injury from flying metal caps of carbonated mineral water bottles. METHODS Retrospective review of ocular injuries due to metal caps of carbonated mineral water bottles. RESULTS Sixteen ...

Migration of formaldehyde and acetaldehyde into mineral water in polyethylene terephthalate (PET) bottles.

The levels of formaldehyde (FA) and acetaldehyde (AA) in polyethylene terephthalate (PET) bottles and in commercial mineral water are reported. All the water samples bottled in Japan contained detectable levels of FA (10.1-27.9 microg l(-1)) and AA (44.3-107.8 microg l(-1)). Of 11 European bottled water samples, eight did not contain either FA or AA, while the remaining three had detectable lev...
