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...

Strategies For Aluminum Recycling: Insights From Material System Optimization

level, the primary decisions for a remelter involve composing alloy batches by carefully selecting and mixing various amounts of scrap and primary materials. Sorting provides added flexibility as well as complexity to these decisions by affording the secondary processor the opportunity to upgrade the materials which they have at hand. With sorting, the set of operational decisions include what ...

Optimization and Control of Chromium Recycling Technology

This paper describes a proposed comprehensive computer controlling and displaying system for a recycling technological process of both liquid and solid wastes from the tanning industry. The chromium tannery wastes are potential dangerous for the environment. As an experimental laboratory model were built in the Department of Automatic Control Faculty of Applied Informatics Tomas Bata University...

The Determinants of Household Recycling: A Material Specific Analysis of Unit Pricing and Recycling Program Attributes

This paper examines the impact of two popular solid waste programs on the percent recycled of several different materials found in the residential solid waste stream. We examine a unique, national, household-level data set containing information on the percent recycled of five different materials: glass bottles, plastic bottles, aluminum, newspaper, and yard waste. We find that access to curbsi...
