Plastics are manufactured in different forms such as moulding pipes, sheets and films. They are formed or expanded to produce materials of low density. Dissolved in solvents or dispersed as emulsions, they are used in paints, varnishes and adhesives. At present, plastics find use in buildings mainly in thin coverings, panels, sheets, foams, pipes etc. skilful use of plastics will expand the usefulness and life of conventional building materials and help them to function more efficiently and
I. Plastic, what have you done? First and foremost, plastics have made a great impact on our lives. Plastic was an innovative material that was invented by Leo Hendrik Baekeland in 1907, who was living in New York state. The word plastic comes from the Greek word πλαστικός (plastikos), which means "capable of being shaped or molded".
Plastic is a necessity to everyday life as we know it. Throughout a normal day, plastic is interacted with countless times in some form or another. Being such a versatile and cheap material, it is a no brainer as to why it is used so frequently in disposable forms. Ranging from bags to bottles, and from containers to cups, the uses for plastic are widespread. As valuable and important as plastics may seem, based on how often we use them, they are often not thought of as such.
The huge amounts of plastic thrown away every year are enough to circle the world four times. According to Oxford dictionary plastic is “ a synthetic material made from a wide range of organic polymers that can be formed into shape while soft, and then set into inflexible or slightly flexible form”. It was invented by John Wesley Hayatt in 1869. Today, almost 260 million tons of plastic is produced a year. Plastic does not decompose and it stays on the surface for decades, which led to environment and health problems.
1. INTRODUCTION Plastics are manmade molecule of long chain polymer. Substitution of natural material by synthetic polymers started more than half a century ago and the plastic became an indispensable part of life. (1) Stability strength and durability are the main features of plastics which impress all the mankind. With time these features are improved.
The first man-made plastic was invented in 1856 by Alexander Parkes. It is a great invention that changed the whole world and opened a new era of human’s history. ( https://en.wikipedia.org/wiki/Plastic#History ) Nowadays people cannot live without using any plastic, from the coffee cups to the keyboard that I am using to write this paper, there is no way that people can get rid of plastic. More than a half century’s usage of plastic, it has already integrated in human’s society. It is a material that is designed to be strong, cheap, durable and easy to manufacture.
Obviously the development of producing plastic went to quick and people did not think of a unified and sustainable way of how to dispose the huge amount of plastic. Unfortunately many countries decided to dispose all the garbage into the ocean but also ship accidents are a reason why so much plastic accumulated in our ocean. Every year more than eight million tons of plastic waste leak into the ocean. A big issue nowadays is that most of the plastic which is produced in one year is used to make disposable items of packaging or other short lived products that are discarded within a year (Philosophical Transactions of The Royal Society, 2009). That means that our use of plastic is not sustainable at all.
Plastic Bags: The Enemy of the Environment Plastic is a commodity that people use everyday which makes daily life easier and safer. People take pills, use cell phones, and wear bike helmets in addition to a plethora of other activities, but tend to forget that one common element in all of them is the use of plastic. One of the main sources of plastic that has been polluting the environment over the last few decades are plastic bags. Plastic bags can be found in nearly every store to hold groceries, accessories, or toys. While plastic bags may provide convenience for customers, there is an overwhelming concern about the effect of them on the health and safety of people, marine life, and the surrounding environment.
The sector accounts for 35% of plastic consumption. (Figure 1) Conclusion and Recommendation on plastic waste management Different innovations have come up to reduce the harmful effects of plastic on the environment in many countries. People use the plastic bags for just five minutes but that plastic bag takes 500 years to decompose. So, people should consider the harmful effects of plastic. These are some of the recommendations for the public: Best way is to follow the 3R’s ( Reduce, reuse and recycle) Reduce the use of plastics as far as possible, reuse the ones that are already being used and recycle the ones which are of no use for other good purposes.
