Map the Supply Chain Paper My significant other and I recently decided to watch a documentary that changed our outlook on an item everyone uses every day, plastics, specifically plastic bottles or bags. In the Pacific Ocean there is a place called the plastic island. This place is a generalized area near midway where the currents drag plastic bottles and other plastic items into.

Concrete + Fly ash Properties of the material Shapes Fly ash consists mainly of hollow spherical shapes which creates a ball bearing effect in the mix, improving workability without increasing water requirements. Fly ash also improves the pump-ability of concrete by making it more cohesive and less prone to segregation. The spherical shape improves the pump-ability by decreasing the friction between the concrete and the pump line. In addition, some fly ashes have been shown to significantly decrease

metal components. The mold material used to make these “molds” could be either temporary or permanent. Temporary molds are made up of refractory sands and resins. The temporary mold has to be broken to retrieve the cast. Permanent molds are made of ferrous materials and are normally employed for casting low melting point materials but this process is too costly. Because of this conundrum, most of the foundry industry has its castings produced using temporary mold materials. Compared to permanent molds

Honestly, I had thought that old electronics can be recycled properly without thinking deeply before I watched this video. When I dispose of the TV in Japan, my mother asked one of the driver of little trucks collecting large items and electronics through a neighborhood to dispose it. Sometimes, we need to pay the fee for disposing. I have no idea where it goes and how it is recycled

Recently, the amount of purchase of the bottled water is significantly increasing because of some environmental problems, such as ocean pollution, that make people to be skeptical about the sanitation of the water.

One the day we were presented with the New Destinations project, the Looney Tunes group quickly jumped the gun on the topic of promotional items. Immediately we started to brainstorm which items would be the best; we came up with carpenter pencils, tape measures, magnets, and drink cozies. Once we narrowed down our choice of promotional items, with the help of Cheri, we sided with magnets and measuring tapes. Quickly, we began to search on the Internet for websites that would give us the best deal

The ban on plastic bottles is something we should participate in because it's a major threat to the environment, they are expensive and poses the major health risk that causes defects. Banning the sales of water bottles at schools would be a great idea because they pose a major threat to the environment. Despite recycling infrastructure that exists in order to facilitate the recycling of these bottles, according to the Container Recycling Institute, 86% of plastic water bottles used in the US become
