Introduction Plastic has become an important part of all our lives for many years, making it one of the most essential assets for humanity. We use plastic on a daily basis and it comes in many different forms. Generally we have two kinds of plastics for commercial use, there are thermoplastics which can be reheated, melted and molded into different shapes and thermosetting plastics which degrade and are converted to other elements if reheated after molding. Most plastics produced for commercial use have certain additives to them which help producers to get desired traits for the plastic, like improved strength. It is these additives that present some of the conflicts associated with plastics, together with the fact that most plastic is not
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.
To recycle plastic one must use low temperatures. Since low temperatures are used residue is still left behind. If higher temperatures were used than toxins would be released. The truth is, plastic does not go away. Due to the negative effects caused from plastic it will always play a role in our environment.
Like all plastics, bio-plastics are made from the combination of polymers. A polymer is substance that is comprised of small molecular subunits called monomers. The process of linking these monomer subunits together end to end that creates a polymer. This either involves the process of dehydration, which is the removal of water from the sugar or through polymerization to cause the molecules to link together in chains. From there on molecularly linking polymers together will make a plastic.
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 U.S. should ban plastic bags because they cause litter, they cost too much, and they can damage to marine life and livestock. To begin, one way plastic bags should be banned is because they cause too much litter. For example, the International Coastal Cleanup in California has collected 7,825,319 plastic bags during the past twenty-five years (1). This shows
Opinions on Plastic Waste Management Introduction Everything that we are using right now starting from a very small container that is used to store foods to things that we use daily like mobile phones; make up, cups are all made out of plastic and will someday become a waste. According to the article inspiration green an estimated of 500 billion to 1 trillion plastic bags are consumed worldwide and takes 500 to 1000 years to decompose. Waste according to AVMA, “waste is everything that no longer has a use or purpose and needs to be disposed” (2016). The purpose of this study is to find out what the harmful effects of plastic are and how one can minimize the use of plastics. Content Plastic wastes are one of the major pollutants and with
This is useful as they are harmless and can be used for storing food and chemicals safely. However this this property makes also makes difficult to dispose of polymers. Therefore they are every so often burned or buried in landfill sites. Landfill Waste polymers that are not needed are disposed in landfill sites. However this uses up valuable and a lot of land.
Plastic In my opinion, there is no reason to keep wasting money on plastic, that is just going to end up causing risk to all living things on this planet. Did you know that about 8.3 billion plastic particles are made each year and about 6.3 million just end up as plastic waste in landfills? But, what happens when the landfills are full? Plastic pollutes the ocean and environment in many ways. Plastic usage is an extremely poor choice for everything and it should be banned because it pollutes air quality for the planet, puts marine animals in danger, and even puts our own lives at risk!
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.
