Sorting Plastic Bottles for Recycling

Using OWL Ontologies for Selective Waste Sorting and Recycling

We are seeing the emergence of the Internet of Things, where digitally enabled objects can interact in smart environments. RFID can play an important role in linking common objects to the digital world. In this paper, we focus on efficient processing of collective waste items. These are considered to be smart by tagging them with RFID which bears the description of its properties. We have demon...

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...

Sorting by Length-Weighted Reversals: Dealing with Signs and Circularity

We consider the problem of sorting linear and circular permutations and 0/1 sequences by reversals in a length-sensitive cost model. We extend the results on sorting by length-weighted reversals in two directions: we consider the signed case for linear sequences and also the signed and unsigned cases for circular sequences. We give lower and upper bounds as well as guaranteed approximation rati...

Sorting of plastic waste for effective recycling

Separation of plastic from various types of waste streams represents one of major problematic process in energy recovery through different thermochemical processes. The sorting of plastics is a very essential step in different waste management technique. Manual sorting is suitable when plastic component are present in large amount but it is a labor intensive process. In automated sorting techni...
