Poly(ethylene terephthalate) Outdated: Is the World Ready for a New Plastic? Abstract: This paper explains the structure of polymer poly(ethylene terephthalate) also known as PET. It states the properties of the plastic as well recycling methods. My goal was to find out what makes PET the number one plastic, both in consumption as well as the most recycled. I also searched for new polymers that are being created by scientists and compare them to PET to see if there was a plastic out there
their resin code, which is a small triangle with a number in it, that can be found at the bottom of a plastic container (CalRecycle 1). In the article “Learning About the Types of Plastic Wastes: Effectiveness of Inquiry Learning Strategies”, the author, Wing-Mui Winnie So, claims that to identify a type of plastic, we should calculate the density of the unknown plastic or verify if it contains a number in the resin identification code. Each plastic has a different recyclability, but the resin code
Plastics play a big role in our lives. The use of plastic has grown exponentially over the past decade. A few reasons why the demand for plastic is so high are due to its strength, very low-density, long shelf life, fabrication abilities and low cost. Plastic are used for packaging, industrial and automotive applications, artificial implants, healthcare, water treatment, conservation of land and soil, housing , security systems, and many others (Siddique, Khatib, & IKaur, 2007). The world’s annual
