Facts about Plastics


Plastics are everywhere. Since 1976, plastic has been the most widely used material in the United States. In 2001, the US disposed of over 25 million tons of plastic. Plastics are the fourth largest category of municipal solid waste. Some plastics are safer than others to use. Below is a list of different types of plastics, which ones to avoid, and which ones are safer to use. Also provided are suggested alternatives to common plastic products.


Types of Plastics

Plastic containers are usually numbered on the bottom, indicating the type of resin used in their
manufacture.
#1 – polyethylene terephthalate (PET or PETE)
Products: Soft drink bottles, medicine containers
#2 – high density polyethylene (HDPE)
Products: Toys; bottles for milk, water, detergent, shampoo and motor oil
#3 polyvinyl chloride (V or PVC)
Products: Pipe, meat wrap, cooking oil bottles, toys
#4 low density polyethylene (LDPE)
Products: Wrapping films, grocery bags
#5 polypropylene (PP)
Products: Syrup bottles, yogurt tubs, diapers
#6 polystyrene (PS)
Products: Coffee cups, clam-shell take-out containers
#7 other (usually polycarbonate)
Products: Medical storage containers, baby bottles, lining in food cans, some water bottles.



Plastics to Avoid



· PVC: Avoid PVC (#3). The manufacturing and incineration of PVC vinyl releases cancercausing dioxins into the environment. Dioxins are then ingested by cattle, poultry, sea
creatures, and other animals, thus entering the food chain. PVC also often contains lead and
toxic plasticizers such as phthalates that migrate into food, water, air, and our mouths (e.g.,
when infants mouth PVC toys). Furthermore, most recycling programs do not accept PVC.


· Leaching plastics: Avoid PVC (#3), polystyrene (#6), and other plastics (#7). All of these are known to leach harmful chemicals such as bisphenol A into the foods they contain. These
chemicals can disrupt proper hormone functioning, leading to a variety of reproductive and
neurological health problems.



Safer Plastics

· Choose plastics that are accepted for recycling in your area. Many people believe that the
simple presence of a code on the bottom of a container means that it is recyclable. The
numbers indicate the type of resin used, but not all types are accepted for recycling. The most
commonly recycled plastics are #1 (PETE) or #2 (HDPE).


· Choose non-PVC cling wrap such as Glad Wrap. Also, Saran Premium Wrap and Saran
Cling-Plus Wrap do not contain PVC or bisphenol A.


· Choose #1 (PETE), #2 (HDPE), #4 (LDPE) and #5 (PP) plastics—these are safer choices
since most research has not shown leaching of carcinogens or hormone-disrupting chemicals
from these. However, #4 and #5 are not as widely recyclable. Some bread and frozen-food
bags and squeezable bottles are made of #4 plastic. Some ketchup bottles and yogurt and
margarine containers are made of #5 plastic. Medela and Evenflo baby bottles are generally
made of safer plastics.


· Choose biodegradable plastics. The use of a corn-based biodegradable plastic called
polylactide (PLA) is growing. For example, Wild Oats supermarket chain replaced its bulk
food containers with PLA. Biodegradable garbage bags and disposable dinnerware are now
available for home use (see www.simplybiodegradable.com). Look for the Biodegradable
Products Institute’s “Compostable” label on certified products, which indicates that the
product rapidly breaks down and can support plant growth after decomposing. Look for
innovative companies who are using Green Chemistry in manufacturing processes.



Alternatives to Plastics

· Glass, ceramic and stoneware do not leach chemicals into foods. Glass recycling is also
more environmentally friendly than plastics recycling.


· Stainless steel containers are 100% recyclable, inexpensive, and will not react with foods
during cooking.


· Wax paper sandwich bags are an alternative to plastic sandwich bags.


· Wood cutting boards instead of plastic are preferable. Spray your cutting board with a mist of
vinegar, then a mix of hydrogen peroxide and water, then rinse, to kill bacteria.

English Edification Enrichment (12)

What is the meaning and origin of the expression "once in a blue moon"? When something happens "once in a blue moon" it happens very rarely. Here are a few examples, * My brother George lives in Russia. I see him once in a blue moon. * We have visitors once in a blue moon. * How often does Tendulkar come to office? Once in a blue moon. There are several explanations as to the origin of this expression. According to scientists, whenever a volcano erupts, the sulphur and dust particles that are thrown up into the atmosphere often cause the moon to appear blue for some time. When the volcano on Krakatoa (an island between Java and Sumatra) exploded in 1883, rocks were hurled thirty miles high into the air and dust from the volcano fell nearly three thousands miles away. After this eruption the moon looked blue for several days. Luckily for us, volcanoes don't erupt every day, so a blue moon continues to be a rare phenomenon. Another explanation offered by scholar...

"Don't count your chickens before they hatch"? English Edification Enrichment (20)

What is the meaning and origin of the idiom, "Don't count your chickens before they hatch"? Some people, as soon as they buy a lottery ticket think they are going to win. They begin to make plans as to what they are going to do with the money when they get it. When you tell such a person "not to count your chickens before they hatch" what you are doing is warning him. You are telling the individual not to celebrate prematurely; you are advising him not to count his profits before he has the money in his hand.

WHAT HAPPENS IN AN INTERVIEW?

  Y ou might generally meet two to five persons (interviewers, recruiters, or hiring managers) sometimes they begin the interview by explaining shortly what the company does and what they are looking for in the candidates relating to the advertised job. Job interviews differ from one another, but they have some common features. The kind of interview and how many levels of interview you will go through depends on the type of position you are applying for.   It is perfectly normal to be nervous which the employers understand beyond that a firm handshake, proper eye contact, and a pleasant smile would add to your advantage.   Being professional, being on time, dressing appropriately, and having required information about the company will show that you are serious about what you want.
