Why does waste glass use in road constructions? Nowadays, all the products we use, whether they are metal, solid, plastic, wood, and glass, will eventually turn into trash that must be disposed (Khalil Nabil Dalloul, 2013). As a nation, USA produce largest waste than other country around the word with 2.04 kg (4.6 pounds) of waste per person every day (https://en.wikipedia.org/wiki/Waste_in_the_United_States).
Also, increasing energy cost and environmental concerns encourages the improvement of utilizing pollution-free, recyclable engineering materials that expend less energy to make (Chui-Te Chiu, Tseng-Hsing Hsu, Wan-Fa Yang, 2007).
The smart method to manage these wastes is to recycle and reuse them as raw materials or modifiers. This

The disposal of waste glass is not a simple matter because it isn’t burned and decomposed material. Waste glass utilizes in pavements as an alternative to the gravel in the pavements so as to guarantee the sustainable management of the waste glass (Khalil Nabil Dalloul, 2013).
Saving energy, promoting future development, and decreasing environmental waste when Glass recycling in pavements construction. Glass is a transparent material that is brittle, rigid and simple to pulverize to frame agreeable particles for applications of roads construction (Wu, S. et al.,

et al., 2003). The big amounts of waste like tires, concrete, glass, slag, steel, plastics etc.) collecting in landfills and stockpiles around the world which are causing disposal problems to financially and environmentally expensive. One answer for a part of the waste transfer issue is to reuse and utilize these materials in the development of interstates (Arnold G. et al., 2008).
Waste glass increases during late decades because of a perpetually growing utilization of glass products. There are two kinds of waste glasses found two kinds; colorless glass and color glass. Most colorless glasses recycle successfully. But most quantitative of color glasses throws into landfill areas. Today landfill areas decrease and it became more complicated. Also, glass is not biodegradable that does not create green natural. So depend on these points, recycling of waste glass took more concern late decades (Seung-Bum Park, Bong-Chun Lee, 2003).
Glass is a transparent material framed by fusion a mixed materials like, soda, silica and other components at high temperature took after by cooling without crystallization. We can get particles same natural sand and aggregates when waste glass crushes (Gautam, S, Srivastava V & Agarwal V.,
To understand the state of glass we must first have an understanding of the different states of matter. All matter is composed into states, and may move through these four existing states. The solid state is where the atoms of a substance are closely pact together with the only movement being the vibration of the atoms. The liquid state is where atoms are placed together in no order with a definite volume, but may move past each other giving it no definite shape. According to Science Magazine’s article in 1926 , glass exhibits traits from both of these states. It is similar to a liquid in that its atoms are randomly arranged, yet it has the fixed rigid bonding of a solid as well as the same high heat capacity(Science). This article in Science Magazine is a bit dated though and science changes drastically through years, especial...
With the disposal of solid waste from process, manufacturing and its waste pose considerable challenges for many organizations. Since, landfilling has become limited, and with the cost of waste disposal continuing to rise, they needed alternative measures.
In conclusion to this investigation one thing is clear and that is that recycling reeks benefits to the environment, Recycling material when compared to making material from raw material is a more efficient energy saving and more environmentally friendly way to reuse material that is usually consider as trash such as empty glass, and plastic bottles, or old newspapers. Recycling helps reduce the possible carbon emissions greatly and does reduce the human carbon footprint. But Recycling doesn’t resolve the pollution that is around the world today. Leading to new questions, questions like what about the landfills are they sustainable, and if so for how long. How long until the air becomes unbreathable? How long until Earth becomes its own furnace?
Consequently, new techniques to deal with garbage have been attempted.. Recycling is but one example of a solution. Through recycling, old products like aluminum cans and glass bottles would be made into new products. While recycling has enjoyed success in the United States, many question its efficiency. Other suggestions range from shipping garbage to other areas to incineration. All these proposals to the garbage problem go under such scrutiny and examination in an effort to achieve some perfect solution to the disposal problem.
In smaller towns trucks having 5–9 ton capacity are used without adequate cover system. Stationary compactors, mobile compactors/closed tempos, and tarpaulin- covered vehicles are used in the transportation of MSW and about 65, 15, and 20% of waste is transported through these compacters, respectively. The maintenance of vehicles used in for transportation of waste is usually done in workshop run by ULBs but most of these workshops can do minor repairs only. No wonder, in the event of breakdown of these vehicles, the overall collection, transportation, and disposal efficiency reduces drastically. Only few transfer stations can be found in some metropolitan e.g. Mumbai (Joseph,
For next year, 2015, the company is trying to assure that 100 percent of its glasses are recyclables because in 2009 they did not succeed (n.d., 2010).
A. Recycling is the recovery of useful materials such as paper, glass, plastic and metals from the municipal solid waste stream to use to make new products, reducing the amount of virgin raw materials needed. (http://www.epa.gov/waste/nonhaz/municipal - I plan to cite on PP)
Minimise waste generation, enhance recovery and recycling of material and develop eco-friendly waste disposal practices.
When addressing this issue, it is necessary to discuss the cost of curbside recycling, which outweighs any economic gains. Second, it must be made known that the recycling process wastes more natural sources than it saves. For these three reasons --economic, environmental, and experiential—curbside recycling should ...
Do you hate seeing litter on the streets, or seeing and smelling heaps of garbage sitting, and rotting away? Humans recycling more will help to reduce this. We throw many things that can be recycled. Recycling glass, plastics, paper, and metals will reduce solid waste dumped into the ecosystem daily. “96 percent of U.S. plastic, and 50 percent of its paper, goes into landfills. Mexico, not exactly a bastion of environmental awareness, recycles more glass than the U.S.” (Alice Horrigan 1). That’s 96 percent of the millions of tons of plastic, which will outlive most of us in a landfill that we could recycle and keep it out of our landfill. Paper is made from trees, if we recycle it, we can decrease our rate of ugly deforestation and the destruction of animal habitats. When paper gets to the landfill, it is guaranteed to get wet. The wetness and decomposition of paper atracts mold spores, which produce an odor and are potentially bad for your health. Also k...

Environmental health has been a very important issue to talk about internationally these days. We, human beings are leading the earth toward its edge unconsciously. We are using natural resource more than we give to the Mother Nature. Day by Day, people are aware of what damage they do the environment, but they do not care of fixing this damage. In a very simple step, the road of a better healthy environment will begin; recycling is the best idea that illustrate the previous point. To Andrew Roper, recycling is the conversion of waste products into new materials, such as waste paper that can be converts into new paper goods (n.d). There are many types of recycling, for example, there are glass, paper, metal, plastics, textiles and electronics recycling (Evans , 2011). This research will focus on recycling papers in the United Arab Emirates, the benefits or recycling and its effect on the environment, the difficulties of recycling, the process of recycling paper, and the finals products of recycling.
There are also several long term benefits of recycling. For example, “collecting and processing secondary materials, manufacturing recy...
The average resident produces seven and a half pounds of garbage every day that is buried down in landfills and litter lands, costing a great amount of money. Nowadays, people face no more critical problem than the need to save the weakening environment, mainly in urban areas, where solid wastes are uselessly dumped. It has been observed that cities have no controlled structure for garbage disposal. Each year, millions of dollars are spent picking up litter and more is thrown away in valuable materials that could be recycled. As humanity develops new technology and equipment, the level of waste increases every day.
The solid wastes are produce not only by households; it’s contributed by hospitals and corporations. Hospitals throw away bandages, use needles and latex gloves, these items hospitals throw away daily all the time because they can’t be reuse for the safety of its patients. Corporations throw away a lot of waste as well such as papers that they use whether in writing or in projects. All of these leftovers after consumptions are waste that is produced by our daily actions.
