Plastic Water Bottles Production By: Arjun Vaswani To: His Supremacy, Terence Donohue, President of Mbantu Production Process Uses a lot of energy to make plastic bottles Toxic chemicals are mixed with oil and water. Often native or elderly people work for the plastic water bottle companies which displace them. Their resource has been taken. Need money They risk their lives working in Factories with toxics Toxics in - Toxics out Bisphenol A Facts on Production Production of plastics has increased over 2000% since Bakelite was first produced. The production of plastic emits substantial amounts of toxic chemicals( eg. ethylene oxide, benzene and xylenes) to air and water. Millions of dollars are spent yearly in plastics research, trying to find new plastics and to improve the existing ones. Effects of BPA on people Bisphenol A (BPA) is found in #7 PC, considered to be another dangerous plastic. Type 2 Diabetes may develop because of BPA, since it can disrupt the proper function of the pancreas and insulin production. The problem with BPA contamination from polycarbonate water containers first came to light in 1998 Manufacturers have quietly substituted other, safer plastics for their baby bottle products since the BPA leaching issue. Effects of chemicals on environment Many tend to be gases and liquid hydrocarbons, which readily vaporize and pollute the air. Many are flammable and explosive. Ex: Cancer Alley, Louisiana State of California Did you Know..as of 2003, 1 billion plastic water bottles per year entered the states landfills PET(Polycarbonate Plastic) Polycarbonate plastic bottles and containers are identified by the plastic recycling symbol #7. This is used for a wide variety of plastics and plastic mixtures Production of PET Making a kilogram of PET, which is enough for around 30 one-liter plastic bottles, takes around 3 liters of petroleum. More energy is then required to turn that PET into bottles, to filter, to ozonate or purify water. W
