Use Of Waste Plastic On Flexible Pavements Essay

Overall, recycling plastic benefits the environment, the economy and the future of America. Although there are flaws to recycling plastic such as the sorting step overlooking additives and the washing step leaving some impurities, technological advances and more labor will be needed to fix those drawbacks in order to conserve the environment. Therefore, the U. S government should mandate recycling so that the recycling rate increase. Through this action, America will gain the benefits of recycling plastic. In addition, Americans should recycle specific types of plastic such as PET and HDPE as those two are the most commonly accepted by recycling programs. This will be strenuous upon Americans because they will have to do more work however,

Plastics are, by definition, “a class of material that has one or more polymers as its primary ingredient, that is shaped by flow when it is processed (usually using heat), and that is solid in its final form.” They’re usually composed of a combination of polymers, plasticizers, and one or more additives, according to GreenPlastics.com. By changing ingredients or quantities of each s[1]

The Cape Cod area typically enjoys moderate weather in every season. Summers are seldom as hot as they are in many locations that are not far away. In fact, if the temperature reaches the upper 90s, it is quite likely to set a new record for the highest temperature ever measured in the area. Unfortunately, however, the balmy temperatures can lull pet owners into a false sense of security when it comes to walking their dogs on asphalt pavement.

The recycled pavement has been designed for a traffic loading of 35 million standard axles (msa), which exceeds what was previously seen as a limit for this recycling technique (30 msa). However, due to the development of recycling technology and the reducing

People would say that plastic in landfills would just stay there and if we keep on using plastic the waste problem would just worsen. I think that the problem here is why do people put plastics in landfills mixed with biodegradable materials. There are ways to properly recycle plastic. This comes to my third argument for why plastic beats paper. It is better because we could change its physical shape to things we really need. Richard Stein, from the University of Massachusetts, stated that plastics could be melted and formed into different structures such as propellers for wind turbines, food containers and many more [3]. Imagine being able to reuse plastic as long as the quality of it can still be recyclable, but if it isn’t anymore, Richard Stein also suggested that plastic could be converted to energy by burning it since it is made of petroleum [3].

For experiment one you will be testing road surface, and seeing if it will affect the speed of the hot wheel car. Before you begin your experiment, you will need to set up your tracks. Tape the two yellow tracks together,line them up and tape the front and back. Then take the top of the track and tape it to the left side of the desk in the back of the room, be sure to tape it 72 cm high. Once you tape the top, tape the bottom of the track 97 cm away from the base of the desk. Step four is to get 40 cm of the material you are testing, the floor, sandpaper, and wax paper. Use a stopwatch to conduct three trials for each surface material, from the top of the track to the end of the surface material. Finally, record the results in a data table

First, concrete durable. Concrete is something that will outlive other products up to three times over (“What Makes…”). In addition to durability, concrete is efficient. Concrete can be made with byproducts from power plants, and other aspects of manufacturing. Concrete is primarily made up limestone, the most abundant material on Earth. Above all of this concrete can be recycled. Concrete can be crushed and recycled into another structure or product, reducing the need to mine the limestone for production. Concrete also allows water to pass through which reduces the chance of flash flooding, erosion, and water table depletion as compared to other materials. This is a major check in the sustainability of concrete; the conservation of soil, landscape and ecosystems. Concrete is a very green option when it comes to building

Plastic roads would be a practically maintenance free product. It can withstand temperatures up to 212° Fahrenheit (100° Celsius) and as low as -40° Fahrenheit (-40° Celsius). Plastic is known to take long lengths of time to decompose. Depending on the type of plastic it could take anywhere from 10, to 100 years for even a miniscule amount of plastic to decompose. Not only does this make maintenance less frequent, but it also could increase the average lifespan of roads up to 3 times.

The growing plastic problem is becoming an issue, because people introduced plastic to the environment. Plastics often coming from microfibers in clothing, nurdles from plastic snow, and other plastic products being found in the ocean, often in floating islands of plastic trash called gyres. In a study conducted by professor Kenji Miyamoto, in the article “New plastic-eating bacteria has potential to ease world’s trash glut” by Ken Mathiesen has stated that these issues need to be worked on, million of tons of suffocating debre show in our oceans every year coming in the realization of one-third of all plastics end up invading the environment. Showing these numbers show some realistic effect of how a total of rubbish ends up in our environment,

Concrete has been used to build roads in America; although this is an expensive alternative to asphalt, it holds more advantages than normal asphalt. Concrete is more durable than normal asphalt and is capable of giving drivers better gas mileage. Concrete roads have also been proven to be more skid-resistant with the addition to grooves to the concrete. It can also help drivers save more gas money since it’s been proven to be fuel efficient. With the advances of modern science, scientists and concrete manufacturers have created some ways of creating concrete in a cheaper way so it can be used more often in creating

Plastic debris and litter is a serious pollution that is currently affecting oceans, waterways and coastal lines. Plastic is a man made tangible substance made from a range of organic polymers such as polyethylene, PVC, and nylon. This material is high on demand with the human kind but takes an average of 450 years to disintegrate. This product is impacting the marine environment, wildlife, and then eventually circling back to humans. Currently, the world’s biggest plastic patch is located north in the Pacific Ocean, trapped in what’s called a gyre (known as an ocean rip). There are also another two plastic islands located in the Indian and Atlantic oceans. These three plastic patches contain a higher amount of plastic but to today's count, in total there are 5 forward. Sea Education Society scientists studied plastics in the Atlantic and calculated there are 580,000 pieces of plastic per square kilometer. Causes of plastic are endless, but trash is the main contributor. Plastic is located in almost every item around, and once it's in the trash, all the garbage gets dumped in land fills and seeps into the ground and soil affecting wildlife. Plastic is cheap and substantially available, so over production of plastic is high. The cause of plastic filling up land and oceans is a couple of reasons. People normally have a one-time use for plastic then throw it away but after that, the plastic is hard to eradicate. Burning plastic leads

For my project, I planned to refuse any plastic bags offered to me and use reusable bags instead. My goal was to use reusable bags and no plastic bags whenever I went to the grocery store or shopping. After researching the effects of plastic on the ocean, I wanted to do my part to help reduce my own plastic waste. Although I was not 100% successful in my effort to eliminate my own plastic use, I still benefitted from this project. It forced me to be much more conscientious about my own plastic use as well as the plastic usage of others.

Sustainability is of vital importance because anything we decide to do as a society will definitely have positively or negatively impact on the natural environment. When unsustainable action continues, they can harm the human existence by creating greenhouse gases that causes climate change, depleting natural resources that are needed for future energy and infrastructure, and polluting the air, soil, and water on which humans depends on for existence. We must change the way we procure materials, construct infrastructure and conduct our daily activates in other for these impacts to reduce (FHWA 2013). The benefits of sustainability in road maintenance as recognized by Kirkup and Allen (2015) are listed

We know that nowadays plastic is the one materials that widely used by human in all of the country. Most of our goods become from plastic. The bad news is, plastics wastes that come from our unusable goods end up in the oceans. There are 60% to 80% plastic wastes on the sea are coming from the land and it will cause a big problem to 267 sea species in this world (Moore, Lattin, & Zellers). That one example is more than enough to start recycling our plastic waste. We can start from reduce and reuse first. For reduce example: when we buy something, we should prepare our own bag to put the goods we buy, dispose the waste according to the bin that specially provided for plastic, use a refill bottle for our drink bottle, and prefer a paper bag than plastic bag. How about reuse plastic bag? Some of countries have creative company that selling fine art and use plastic waste as the basic materials. One of the countries that have company like that is Indonesia. Indonesia has a lot of home industry that use plastic waste as their main materials. They make new thing from plastic bottle, such as plastic flower art, windmill toys for children, table lamp, and house accessories. Some schools in Indonesia teach the students how to reuse the plastic waste and make a fine art from it. Reduce and reuse the plastic waste already counted as recycling the plastic waste. Never think

This research question aims to think deeper on the circumstances of the overuse of plastic and paper, and what could happen more to the animals/birds, our environment, and our bodies if consumers keep on using plastic and paper products. This research question should be asked to raise awareness to users and most importantly designers, so they consider using other eco friendly material in designing their products.
