Question

Recycling Your textbook discusses plastic polymers and how to recycle them. What are the pros and cons of recycling? Do you recycle? Does your neighborhood recycle? While there are many types of recycling: glass, aluminum, electronics, etc., I want you to post of plastic recycling. How do the physical properties of alkenes and alkynes change when a polymer is made, or then recycled? To earn all of your points for this post, you must answer the questions above.

Answer 1

Dear student, I actually do not know at what standard do you study. But I am trying to answer your question in a generalized manner. Yes we all trying to recycle plastic, because it Is very much necessary for our environment. But we should more aware about plastic replacing. Plastics are non-biodegradable. Every year, millions of plastics got dumped in our oceans, which is hampering our sea-plants and animals and this also cause if global warming. Plastic recycling is more tough that metal recycling because of their low density. Process of plastic recycling pyrolysis - here the plastics are exposed to thermal decomposition to produce oil is petroleum products, pyrolysis oil, hydrocarbons and carbon black. In pyrolysis larger molecules are thermally cracked at a temperature of \r\n 400 degree c in absence of oxygen. By pyrolysis, renewable energy source is being utilized to produce fuel, and land and ocean pollution gets reduced. Heat compression it is another process where plastics are first collected, cleaned in all forms
