Recommended: Law of thermodynamics
The second law of thermodynamics involves the concept of entropy, an idea that explains disorder in our world. The concept of entropy associates useful matter and waste with low entropy and high entropy, respectively. In order to look at entropy, we must first define the system of interest. For the remainder of this paper, the system will be Earth. Many people believe that everything we use up can be recycled and reused if we can develop the appropriate technology. However, the Second Law makes it essentially impossible to achieve complete recycling. Work must be put in to recycle waste; such an idea seems to work against the idea of the Second Law. From an economical standpoint, I believe that it is not worth recycling wasted goods according to the ideas of the Second Law of Thermodynamics. In the following paragraphs, I will demonstrate how entropy is objective as well as explain the energy consumption of recycling.
The concept of entropy is objective. In contrast, resources, contaminants, and wasted goods are subjective. The objectiveness of entropy relies on the following question: why should humans be the criteria to determine the value of matter and whether recycling is worth it? To determine whether matter is worth recycling, we must not only look at the input energy but also the relevance to a particular society. In other words, what is considered a wasteful good not worth recycling for one society could be worth recycling for another society. Therefore, the objectiveness of entropy in terms of the value of recycling really depends on the society and whether the costs of recycling are less than the costs of making new products. Looking at our system, I believe that the energy required to recycle works against the Second Law because of the organization caused by recycling (opposing the Second Law)..
In order to recycle a used product, we must insert additional energy in the collection, transportation, and recycling of used materials. This energy consumption contributes to the overall entropy of the environment. Thus, waste can be recycled only by the expenditure of additional energy and at the expense of increasing the entropy of the system as a whole. Recycling could be worth our efforts if society would be able to coordinate the rate of production into useful, low entropy resources. According to
Dr. Mayumi, "the economic process consists of two parts: one is production/consumption in which raw materials are transformed into useful economic goods, and the other is consumption in which low entropy inputs are utilized, ultimately resulting in high entropy wastes.
Barlaz says, “Recycling still causes some emissions” (62). However recycling starts at home with the consumer. When people go out to buy groceries, clothes, food or any other things they should think about the purchases before they buy them. Consumers buy groceries but they chose to use plastic or paper bags. Instead of using those they could use reusable cloth bags. Some people would rather use the plastic or paper bags. If they do then they should recycle those bags instead of just throwing them away in the garbage and hoping they get in the recycling area. Recycling cans and glass jars saves energy needed to make new ones. People can save energy by recycling other things like paper and plastic. Humes says, “Recycling aluminum cans saves ninety-six percent of the energy needed to produce aluminum from bauxite ore” (260). Also, “recycling the glass jars and bottles saves twenty-one percent of the energy needed to make new glass” (260). So if everyone could start recycling their cans, glass, paper and plastic that would save us a lot of energy that would need to be used to make new ones. If we can start recycling at home that will make things much easier on the waste management plants and our world. If people don’t want to recycle at their homes and separate everything they can just put all their trash in the can and it will eventually be separated and recycled. As people become more educated about
Let 's take a look at the points from the article 10 ways recycling hurts the environment, by Andrew Handley. The number one point is that recycling gives false promises, but how? Andrew Handley says, “The biggest reason recycling hurts the environment doesn’t have anything to do with the technical process—it’s the mindset it gives people. Recycling’s main impact is to convince us that it’s okay to be wasteful in other areas, because we make up for it through recycling. It encourages consumption, rather than pointing out ways to reduce consumption overall.” Honestly, the biggest reason people don 't recycle is because they are plain lazy, there is no way to sugar-coat that. People don 't want to take the extra 10 seconds it would take to get another bag for the cans or bottles. They just don 't care.
Recycling is the practice of reusing old products to create knew ones in order to essentially “re use” them. In theory, this process is supposed to work perfectly, but because of other factors it doesn’t. The whole idea of recycling is supposed to lead, eventually, to a world where everything will be recycled and used over and over again; thus, no more mining, cutting down tress, and other jobs that require people to do some sort of labor in order to create a certain type of object. The process of recycling would in due time, end these types of labor. Recycling is not entirely a good thing because not everyone does, it requires unnecessary funds, and it takes away many jobs.
If everyone recycled then there would be less need for new materials to be made out of unused resources; instead they would be made with recycled materials. Recycling saves a lot of natural resources because every time you turn something into the recycling center part of that is reused on a future product. In fact I read once, that each aluminum can that is recycled, a quarter of that is used on a new can. That twenty-five percent can add up in the long run. When people don't recycle that plastic bottle, aluminum can, or glass bottle that is in their trash can it is only used once and then is sent to a landfill just to take up space.
Some people say recycling is a waste of time. If one is a very busy person, then maybe. But taking that extra two seconds to recycle, saving energy, money, resources, and the world isn’t a bad plan either. If everyone would take the extra two seconds to recycle, the extra effort would help to make the world would be a much cleaner and more efficient place. Recycling could also help to lower taxes in the long run. Recycled materials have value, and trash costs money. A city recycling program could sell it and make money. Then, with the extra money, the city wouldn’t have to charge as much money on taxes. Now how does those two extra seconds sound now? One can better the place they live in and save some money by taking two extra seconds to recycle.
Thermodynamics is the branch of science concerned with the nature of heat and its conversion to any form of energy. In thermodynamics, both the thermodynamic system and its environment are considered. A thermodynamic system, in general, is defined by its volume, pressure, temperature, and chemical make-up. In general, the environment will contain heat sources with unlimited heat capacity allowing it to give and receive heat without changing its temperature. Whenever the conditions change, the thermodynamic system will respond by changing its state; the temperature, volume, pressure, or chemical make-up will adjust accordingly in order to reach its original state of equilibrium. There are three laws of thermodynamics in which the changing system can follow in order to return to equilibrium.
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
Recycling is one of the easiest ways to save energy for all the living things on Earth. Recycling save energy because using recyclable items that are not recycled can take a lot of energy. Recycling often saves energy because the products being recycled usually require much less processing to turn them into usable materials. Sometimes recycling can also save energy for goods which is
I. Significant amounts of waste is generated in society and that waste has a detrimental effect on society,
Recycling was first thought of in 1776 during the war of Independence from England. Americans recycled scrap metals to help fight the war. But it wasn?t until 1895 when the first residential waste program in the U.S. was invented in New York. The chemistry behind recycling is the idea that 'everything circulates'. For instance, if you saved a box of cereal and put it into your recycling bin, that box of cereal can be made into a package of papers, or a newspaper, or a tissue box, and the possibilities are endless. Common household items that are recycled are newspapers and paper towels, aluminum, plastic, glass soft drink containers, steel cans, and plastic laundry detergent bottles.
Therefore, many countries in the developed world have adopted recycling policies for disposal Of waste. The benefits of the recycling process include the following. Maintaining the cleanliness of the environment in the first place from the damage of burying and burning the waste or leaving it exposed Reduce the pollution of sea, ocean and river waters from dumping solid waste, threaten marine life, and reduce groundwater pollution from the waste of
As humanity develops new technology, the magnitude and severity of waste increases. When computers were developed, it widely was believed that the need for paper would be eliminated. On the contrary this was widely proven false and we are now utilizing more paper than ever. Canada is not an exception as the typical Canadian generates an average of three pounds of solid waste each day1. This alone shows what a careless species we have become- using and disposing materials without even considering the damage we are causing. With half a trillion tones of waste around the world, only 25% may be reused for a second or third time and less than 5% can be renewed limitlessly1. These facts are true only in developed countries. Since these traditional waste reduction methods have been proven inefficient, we must endorse new innovative technology to arrive at a solution.
The United States produces “about 8.25 billion tons of solid wastes each year” (Russell 1). People do not realize the impact they have on our planet and environment. When people throw anything in the trashcan, they are contributing to the destruction of our planet. The number landfills in the United States are decreasing, but the amount and volume of waste being thrown into the new landfills is increasing (Russell 4). Because of this escalating amount of garbage, Methane which contributes to global warming is an outcome of these landfills (Russell 7). As a result, our planet is suffering because of this epidemic. The garbage being put in the landfills could be recycled, but not enough businesses, ...
On the other hand, some people feel that recycling should not be mandatory. Some people feel as if recycling is not always cost effective. Sometimes, there may be a need for new factories to process reusable materials. This could even create more pollution because of the cleaning, storage and transportation that takes place. Also, some people feel that recycled products may not last for long. Recycled materials are not always a reliable quality. The materials are mostly made up of trashed waste, which is why the products are cheap and last for a shorter period of time. Another reason why some people think it is not necessary to recycle is because there are unsafe and unhygienic recycling sites. Places like landfills, where all sorts of waste is dumped contribute to the spread of different diseases and other dangers caused by harmful chemicals and waste. People also think that r...
This process saves energy, and conserves resources by reducing the amount of renewable resources that would normally end up in a landfill or in an incinerator. These recycling plants “increase jobs in manufacturing while simultaneously increasing the Unite State’s competitiveness in industry. ”(Recycling | Reduce, Reuse, Recycle | US EPA.) There are also several long term benefits of recycling. For example, “collecting and processing secondary materials, manufacturing recy... ...
