POLYMERS 1. Polyethenics ( Vinyl Resins) They are obtained by the polymerization of monomers containing the ethylenic bond (-C=C-) I. Polyethylene ( PE ) Polyethylene is one of the simplest and most inexpensive polymers. It is a waxy, chemical inert plastic. It a thermoplastic formed by the addition polymerization of ethylene. There are two types of polyethylene  Low Density polyethylene (LDPE) By using free radical indicator, LDPE is obtained  High Density polyethylene (HDPE) Using ionic…

Microplastic pollution in the Great Lakes is a fairly new environmental issue, but it is growing rapidly and requires our attention in order to minimize and ultimately stop it. Microplastics are plastic particles in smaller size scales, usually particles less than 5 millimeters in diameter (Eerkes-Medrano et al. 2015). Recent research has documented microplastics in ocean habitats worldwide and specifically in the Laurentian Great Lakes and studies have found that microplastics interact with…

If you are someone who likes to build things yourself, then you may already be familiar with the woods that are available to you. Ideally, for your next project you will have a good idea of what type of wood you want to use, but if you don't, you'll have to figure this out.

All around school there were candy wrappers, biscuitville bags, plastic water bottles and other various items that never seemed to make their way into the trash cans.
