Plastics

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…

one of the reasons why it has become popular. Insulation is necessary to protect the roof from weather getting into the cracks of the wood shingles on the roof. If left alone for a long time, this can cause some damage on the roof. Installing foam plastic on these cracks will protect the roof from further effects of weather. It is in liquid form, which expands several times its initial size when sprayed on a surface. The spray foam is polyurethane foam or SPF that is used to insulate almost…

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…

filled with so much trash. Not only has the land become filled with trash, but the oceans and bodies of water around us have become more polluted with trash. What people do not understand is, it is not very hard to pick up a piece of paper, or a plastic bottle that is lying around them. Our country’s citizens have become too lazy to care about what our country looks like. These pieces of garbage are not only making our country’s environment look bad, but is putting a lot of animals, and marine…

Plastic has been becoming more and more important since 1900’s and nowadays we cannot survive without it. In general, the major features of plastic are durability, light weight and low cost but these good properties also generate great problems to our environment. Current levels of use and disposal generate several environmental problems. Around 4% of crude oil is used as raw material for plastics and 3 to 4% extra are consumed to provide energy for manufacturing process. The major usage is…

so much litter. It was so easy for us as a community to just properly dispose of our trash, but we never did. 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. In my neighborhood there were cans, cups, and plastic bags. It felt like my home and community was being consumed by trash, so I decided to do something about it. I decided to voluntarily pick up trash around my school and…

Photosynthesis Literacy Task Final Draft There are two different types of Christmas trees you can get during the holidays. There is a fake tree and a real tree. The fake tree is made up of plastic pine needles and it has a stand. The real one’s are natural and are from the wilderness. Some people would consider real trees because they are nicer, but the fake trees should be the best choice. The fake trees are cheaper than the real ones. The fake trees are also good because we need the real…

hurting or even killing animals that you adore because wastes can be dangerous to them. PETA, an American animal rights organization, wrote an article about litter. In the article it showed pictures of dead whales, and because there were so much plastics in their body they didn't make it. The…

polyurethanes were first developed by Otto Bayer and coworkers in 1937. Shortly thereafter, Schollenberger and coworkers used formula modification to prepare elastomeric polyurethane products from Bayer's products that were like nylon or other engineering plastics in physical characteristics. PUs are widely used in coatings, flexible and rigid foams, elastomers, and composites. Reasons for the use of polyurethane coatings include: high performance characteristics such as flexibility, toughness,…

Introduction A blender generally consists of a plastic or glass pitcher that locks into a large base. Some of blenders are made of stainless steel. The lid of the pitcher has a seal that prevents the food or liquid from splashing out while the blender is in motion. The motor has varying speeds that turn either two or four sharp, stainless steel blades. The blades slice, crush and blend the contents of the pitcher..Blender is a must have kitchen equipment for nearly all families today, especially…
