    tons entered the ocean. Effects on people, environment, animals, where does it go? There are 7 types of plastic according to Mercola; “Plastic #1: Polyethylene Terephthalate (PET) is things like water bottles and condiment containers, this plastic is listed as safe but can leach chemicals during production. Plastic #2: High-Density Polyethylene (HDPE) is used for milk, juice, and shampoo bottles, these are considered as a low level of toxicity. Plastic #3: Polyvinyl Chloride (PVC) these plastics

    call home but by using my idea of using/melting plastic (high-density polyethylene) and comparing it to standard building materials that make houses , it will enable hundreds of thousands of people to have a place that they call home and it will create jobs as well. Investigative question: How does a high density polyethylene brick differ from a clay bricks in different tests for construction? Hypothesis: The high density polyethylene brick is more resistant to the construction tests than a

  • Polyethylene: Manufacturing Cycle and Environmental Impact Essay

    891 Words  | 4 Pages

    Manufacturing Cycle and Environmental Impact The most common form of polyethylene is petroleum based or olefins based; as before mentioned polyethylene compounds have a wide commercial applicability and are made from non-renewable resources (Harding, Dennis, von Blottnitz, Harrison, & S.T.L., 2007). Its manufacturing processes are regarded as energy intensive and release significant amount of CO2 and heat into the atmosphere (Broderick, 2008). Next a little more detailed description of polyethylene’s

According to Shifrin (2005):” Water-borne contagious disease still caused devastating epidemics in the early 1900s, compounded by growing, congested populations. Air pollution also grew to a high priority by midcentury because its impact was so observable and immediate.” (p. 676). Generally, these diseases were spread through poor sanitary practices as well as the overwhelming volume of pollution that was generated by so many indivduals with

    Assignment 3 Q1: how does the industry work? Polyethylene is a petrochemical product that has been widely used in the plastic manufacturing, such as packaging, trash bins, and food containers. It is produced mainly from the polymerization process of ethylene, which is an ingredient derived from cracking crude oil and natural gas. There are three types of polyethylene: low-density polyethylene (LDPE); high density polyethylene (HDPE); and low linear density polyethylene (LLDPE), and each of them has distinctive

    investigation was to formulate nitrile butadiene rubber (NBR)/high density polyethylene blends (HDPE) blends using industrial waste (MW) and compatibilized by Chloroprene rubber (CR). Results indicated that the minimum and maximum torque increased with increasing HDPE amount in the blends, whereas scorch, and cure time showed the decreasing trend. Increment in HDPE increased the tensile strength, modulus, tear strength, hardness and crosslink density. % tensile strain, % compression set and abrasion loss

    cells as High density lipoprotein (HDL) and low density lipoprotein (LDL) LDL is known as the BAD cholesterol (10). When the level of LDL becomes more than the level of cholesterol needed within the tissue it starts to disperse the extra cholesterol into the arteries. HDL is known as the GOOD cholesterol. Instead of HDL depositing cholesterol into the arteries like LDL does when there is an excess amount within the tissue, HDL actually carries it to the liver. The liver then eliminates it. High levels
