The Benefits of the Bioreactor in Landfills

In 1969 it was discovered that the site was leaching due to a lack of a bottom liner. The landfill was leaching volatile organic compounds (VOC), polychlorinated biphenyls (PCB) and explosive landfill gases (LFG).

Landfills can be used in many ways. In fact, the gases in a landfill, like methane, can be used to heat our homes, or gives us electricity, but these gases can be minor. To produce this methane gas and others, H2O and oxygen go into the dirt covered pack. Once this happens, the gases go out doing their evil mission: hurting the atmosphere. In a sanitary landfill, operators have to control the H2O and oxygen. If operators cover the pack too early, the pack will go down and pollute for a long time. Lastly, the gases produce the odor of the landfill.

Emelle, Alabama not only holds one of the biggest commercial hazardous-waste landfill in America, but African-Americans make up 90% of the population of the town. A Choctaw Native American reservation in Philadelphia, Mississippi holds a 466-acre hazardous landfill (Wright 532). These statistics have revealed the sensitive boundary between racial and social classes. Specific human factors have driven the need for change in environmental practices, such as growing human population, increased natural resource consumption, and the effluent discharges of manufacturing. This situation has resulted in a significant negative impact on world ecosystems (Dietz, Ostrom, and Stern 1907). What ties both of these critical concerns

Have you ever wondered where all the trash goes that you throw out? Most of it ends up in landfills, gets burned or ends up on the street. Landfills are the most cost-efficient ways to get rid of trash for places like the United States but at what price. When waste disintegrates in landfills and water passes through the waste, the resulting liquid is called leachate. When leachate run off encounter local rivers and lakes it can contaminate the water and destroy whole eco systems that live in these areas. Landfill gas consists of naturally occurring methane and carbon dioxide, which form inside the landfill as the waste decomposes. As the gases form, pressure builds up inside a landfill, forcing the gases to move. Some of the gases escape through

Almost every medical, dental or veterinary facility in North Texas and the rest of the United States produces some amount of hazardous waste, and proper disposal and treatment of this waste requires biomedical waste solutions Texas. Biomedical waste solutions begin with biomedical waste handling and storage. In any facility that produces this type of waste, that means having the proper equipment and training to allow every staff member to handle hazardous materials safely and to know how it must be bagged or boxed until it is picked up for professional disposal and treatment.

Historically, the state of garbage in California has not been that pleasing. Most of the landfills in the State are currently overused as some continues to get worse with time. This probably is the case because by the year 2013, only 36.6% of the entire waste products in United States were actually recycled. Moreover, according to the findings presented from CalRecycle study, the existing organic wastes constitute 32.4% of all the waste product. Sadly, these organic wastes pose a significant threat to the surrounding environment (Donovan). The common practice of burying solid wastes in a landfill is confirm dangerous to the environment because of the chemicals that later build up beneath the earth surface hence producing Leachate, a poisonous

In some parts of the world, human waste is being used as agricultural fertilizer and it is known as biosolids. We have biosolids due to the wastewater treatment process. There are many advantages and disadvantages to the use of biosolids, however, I believe the advantages outweigh the disadvantages. Biosolids create job opportunities, promote farming, is free and is a cost effective of disposal. Using biosolids can cause odours in the area and may affect health as well. Although biosolids can cause odour problems, farmers see it as a free source of fertilizer. It helps produce ample crops. Creating biosolids is a form of recycling which prevents humans from dumping it in landfills. Biosolids have been

Landfills are mostly composed of non-biodegradable waste which takes a long time to decompose. Recycling old and waste products into new products will reduce the amount of waste that enters landfills across the nation. Doing so helps in reducing water and land pollution as landfills are a major source in contributing to destruction of natural environment. Recycling programs keeps enormous amounts of waste from being deposited into landfills every year allowing for unused land to be preserved for other uses rather than another waste site. Also, if we don’t recycle, more and more garbage will enter the landfills until they are all used up. When that happens, where will the new waste be placed and would you like to have a landfill as a backyard? According to the Bear Spring Blossom (BSB), “Landfills are a ticking time bombs-producing unknown gases and chemicals” (“Recycling”). Also, it goes on to state, “Recycling helps to reduce landfill space and disposal costs” (“Recycling”). Even though reducing the size of landfills is a notable benefit, there are other things that benefit from

Landfills are getting bigger and are becoming more of a problem in the U.S because they are hazardous to our health and our environment, but there is a way to stop the villain known as a landfill.

Landfills have many drawbacks to them. Landfills are not the best way to get rid of the waste that the world puts out. Three major harms of landfills are: they can harm the environment and living organisms around that specific, landfills take up space that people could use to make businesses, homes or parks for the kids in the neighborhood, and people throw things away that can easily be recycled.

The breakdown of food waste in landfill releases nutrients, which can migrate out of landfilled waste and into the surrounding environment. Groundwater and waterways will be polluted because of too many nutrients release in landfills. When it is raining, the landfills may leak and the leaking landfills can pollute the underground water by bringing the polluted rain water into the underground.

Global warming is a problem with plenty of scientific evidence to prove the clement change. There is a concentrated amount of carbon dioxide and greenhouse gas causing to reach high temperature the earth has not experienced in 650,000 years (NASA, 2015). The Unite State should pass ever law possible to preserve the earth. Methane gas account for 10% of greenhouse emission in the US (EPA, 2015). However Landfills are the third longest producer of emissions therefor it is imperative to have laws to minimize what is dumped (EPA, 2015). For starters There shoulder a Law that bans the use of plastic bags for industry and households. Using only biodegradable would be break down landfill and would be initially be better for the overall wellbeing

Alternatives: As previously mentioned, Gupta et al. believe current methods of conducting EIAs are ineffective. Therefore, they propose an unconventional method for conducting EIAs for landfill siting: a multivariable calculation of implicated factors using a fuzzy relation, or fuzzy clustering. This involves the attribution of a weight to each qualitative factor, in order to accurately assess the environmental impacts of landfills. This method distinguishes itself from the others because it accounts for the uncertainty caused by the expert’s subjectivity, and for the lifetime of the landfill. The result of this method is a “fuzzy relation between frequency of occurrence and the impact on environment [sic] considering the adverse consequence

What action can states force upon themselves to help save the landfills from destroying the earth? Building new landfills to make additional room for “new” waste is a recipe for disaster. How so? It takes an arm and a leg to build new landfills, meaning the cost of making another one would be higher than what was expected. A founding shows how this relates to being overpriced: New York is very populated, making the state even more crowded by building landfills. Along with overflowing of the state, expenses would be too much to bear (Gelman). Is it a good idea to build these? How would taxes tie into this? Building new landfills could set the stage for an outstanding payment. What else could states do to lower the cost of items used on a daily

Landfills are made up of 6 different parts. Each of these parts are designed to address issues that may occur in a landfill. These parts include the bottom liner system, which separates trash and subsequent leachate from groundwater. The next part is the cells, which is where the trash is stored within the landfill. The storm water drainage system collects rain water that falls on the landfill. Leachate collection system is the next part which makes the landfill up. This system collects water that has percolated through the landfill itself and contains some contaminating substances. The
