Recycling
Recycling is one of the waste treatment methods for which due to value of the material or environmental perspective, the old material (waste) changes to new and usable products. Few materials that can be recycled are: glass, paper, metal, plastic, textiles, and electronics. Few of these will be discussed since Electronic waste contains glass, metal and plastic.

Glass recycling:
The process of making new and usable products from waste glass. “Every metric ton (1,000 kg) of waste glass recycled into new items saves 315 kilograms (694 lb.) of carbon dioxide from being released into the atmosphere during the creation of new glass.(6) The recycling steps for glass are(7):
1- Collection of glass.
2- Sorting of glass: it might be needed to sort the glasses based on their color as well because the glass retains its color after recycling.
3- Processing: Producing glass cullet
4- Processing: Removing contaminants
5- Processing: Making recycled glass
6- Processing: Decolorizing and dyeing
7- Processing: Making recycled glass products

Plastic Recycling:
The term plastic recycling is the processing of waste plastic and turning waste or scrap plastic to a useable condition which can be used in the manufacturing products. Tons of plastic waste ends up in landfill when large amount of it can be recycled. There are two main plastic resins in electronics, “thermosets” which cannot be re-melted and make new product, so it gets shredded and recycled; the other plastic resin that is used in electronic equipment is “Thermoplastics”, which can be re-melted and form new products. There are five general Stages for Plastic Recycling Process (5): 1- Sorting the Plastic. 2- Washing Waste Plastic. 3- Shredding the Plastic. 4- Identify and Cl...

    Many people believe that we should not recycle anymore, but this is not the case. We, the people of the world, need to continue to recycle because we do not want our children to grow up in a world where there are no certain species of animals due to recycling failures. We also do not want our children to grow up thinking that it is okay that they throw their garbage on the ground, and not have to pick it up. We need to teach our children that they need to take care of the earth that they are living on, because they only get one. Recycling is one of the most beneficial environmental issues that we have here on this earth. Recycling saves energy, limits pollution and supports several environmental factors of the economy. “In 2003, the savings from recycling 54 billion aluminum cans exceeded the energy equivalent of 15 million barrels of crude oil- or the amount of gas the U.S. uses in one day,” according to the U.S. Environmental Protection Agency. The EPA estimates that 200 million gallons of used oil are not disposed of properly, and if we were to dispose the oil properly then we could keep the oil from polluting the ground and the fresh water source. According to E. Takatori, “… While on-going societal regulation treats material recycling as the dominant cycle, the properties of recycled plastic remain the most port

    Electronic and electrical equipment is essential part of busy world. It substitutes hard human work and makes it faster. Most of people have a computer at home or at work. In recent years changing of electronic equipment becomes faster due to obsolescence and advance (Deathe et al. 2008, 322). The problem of e-waste threatens the future environment of the modern society. E-waste or electronic waste means electrical and electronic equipment, which is not suitable for use and fills the dumps. Electronic equipment, such as mobile phones, computers, and televisions consist of hazardous materials, which pollute the environment and impact on human’s health. Obtaining of 1.6 billion pounds of lead and four times more pounds of plastic from e-waste had been foretold by the National Safety Council (Hosansky 2004, 20). There is a diversity of ways to solve this problem, but for finding the most effective solution there are some criteria such as environmental benefits, accessibility for people and feasibility. This paper using evaluation criteria will introduce and analyse remanufacturing and recycling. This essay will argue that remanufacturing is the most effective solution by evaluation of two proposed solving.

  • Persuasive Speech On Recycling Plastic

    1157 Words  | 3 Pages

    One huge aspect of recycling is that it gives the recycler the fulfillment of helping the environment. W. Kip Viscusi a professor at Vanderbilt University said, “The warm glow environmental benefit that a person receives from recycling will be greater for those who place a higher value on the environment .” Therefore, the benefit of helping our environment is the greatest benefit of all. Although it might seem as if plastic is thrown away than it can not harm the environment, however, that is incorrect. Plastic is not biodegradable, therefore, it will never be able to completely decompose into the earth. With plastic not being able to decompose it takes up a large amount of space while also being capable of traveling through the air. Sati Manrich, the author of Plastic Recycling said, “The mounting volume of plastic residues, coupled with their extremely low biodegradability, generated a serious problem regarding the amount of space they took up.” Therefore, when plastic is thrown away it will last for at least four-hundred and fifty years before degrading in the landfills; thus allowing all the plastic that was thrown away in the last four-hundred and fifty years to start a stockpile in the landfills or even travel somewhere else.(Manrich
