It is seven of the clock. Do I hear a truck? I need to get the garbage outside! A weekly regimen for all but no one usually thinks about what happens to our trash. Once it is in a plastic bag most people pretend that it does not exist. They tend to believe that waste disposal is an issue for the government and private contractors. While this is true, these people have to decide how to dispose of everyone’s’ garbage. And they have to ask, what impact will this refuse have on the environment and community after it is out of sight and mind?
There are three basic ways that trash is disposed of recycling, landfills and incineration. Each with their own perks and flaws. Recycling has been and will continue to be the worldwide favorite however this method cannot process all waste. The leftover refuse winds up in landfills and incinerators. Which of these two methods of disposal is the lesser evil?
Landfills seem pretty self-explanatory, a hole full of garbage. However it goes much deeper than that, no pun intended. Current landfills do begin with a hole in ground but that hole is lined with layers of dense plastic this process makes sure that no contaminants escape into the soil. These contaminants are called leachates and are caused by water seeping through the landfill. The leachates must be removed every so often, processed and disposed of. Landfills also produce an extraordinary amount of methane. Some, not all landfills collect this methane and either burn it or process it in order to sell the methane as fuel. (Mckinney and Michael 536-37)
Contrary to popular belief, incinerators are not the pollution powerhouses previously thought. There are essentially two types of waste to energy facilities: refuse-derived fu...

...the environment incinerators perform the much-needed duty of consolidating trash. Therefore making landfills fill up much later. This is only a temporary solution eventually scientist must think of another way to dispose of, or utilize our garbage.

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?

Landfills in America have taken many square miles of what used to be fertile land, forests and communities and that trend does not seem to have an end. The waste, we as Americans, dispose of each year is in the tons and that number rises annually. One of the reasons why this occurs is actually quite simple; population. Population in modern day America has soared to well above three hundred million, in 1915 that number was hundred million. Urbanization and industry has given way to deforestation and landfill creation. The need for more landfills has caused many health concerns, issues, and problems to not only those living near and
This book vividly discusses the trash problem in Staten Island, New York. Even with a well defined garbage collection, recycling, and landfill system, the management of Staten Island does loathes scrutiny, hence the reason they ignored Royte’s calls. It also shows how most New York residents are disinterested in making work easier for the garbage collection sector, eventually having a negative effect on the environment.

Incinerators should be on the low end of possible uses of waste. The first option in what should be done about waste is reduce. If individuals keep creating more and more waste without trying to cut some out, it will be a vicious cycle that never ends. The next step in the waste hierarchy is reuse. To reuse means to use a product or material again without really changing it chemically. Some examples of items that can be reused include: plastic bags, jars, newspapers, packaging materials, and even wood. These are items that can be found around a person’s home and instead of throwing it away after the first use, it can be reused for other things or donated for someone else to use. The third step in the waste management hierarchy is recycling. Recycling is the process of collecting and reprocessing materials to make them suitable for reuse. If the first two are done correctly in the series of solid waste management, then by the time recycling comes into play the items have already been used multiple times and has already saved time and money. The fourth step in waste management should be turning waste into energy. This is when the incinerator comes into play but still is not the last step. The final step in the waste management process should be the landfill. This takes up the most space and takes a long time, if at all, for waste to
Waste incineration units produce a lot of carbon dioxide gas approximately around one third of the greenhouse gasses. It also impacts people’s health as they get exposed to the toxic emissions by breathing in the air or consuming contaminated food and water. Additionally, when the garbage gets burnt by the incinerators they end up as ashes which are then emitted from the chimneys, including the toxic materials and end up in specialist landfill sites for hazardous waste.
Our world is getting to the point to where we will be surrounded by trash. There are hazards happening because of the excess trash, which could have been recycled. Although the government is not doing their best to make these hazards stop, surprisingly it is the non-governed organizations that are trying to make the difference. Proven studies and facts have been made about these issues, so people should take this into consideration and start recycling more. Recycling is a beneficial process that is not required globally like it should be because citizens are uneducated on the process and what it can do. People who are not recycling do not know the hazards they are causing everywhere.
Policy is needed to regulate which course of action should be taken and how it should be implemented. Because of this, many plans and policies revolving around the management of solid waste have been put in place. Sometimes however, a particular policy can have its shortfalls, potentially resulting in its negative aspects outweighing the positive ones. According to the Conference Board of Canada Report, “Canadians dispose of more municipal solid waste per capita than any other country” (2013). Solid waste management in particular, involves many aspects, ranging from packaging waste, food waste, etc. (White & Franke 1999), hence, the following analysis revolves around household and commercial waste – referred to as Municipal Solid Waste (White & Franke. 1999) – in the Greater Vancouver Regional District. Municipal waste is a major health and environmental concern as it contributes to numerous problems like habitat destruction, surface groundwater pollution, and other forms of air, soil, and water contamination. Waste disposal methods like incineration create toxic substances, and landfills emit methane, which contributes to global warming. According to the Zero Waste Objective Report, “The impact of climate change and the increasing awareness of the role of “waste” and “wasting” in the production of greenhouse gas emissions is a constant environmental pressure… (2009). This leads to an increasing limitation of government to prevent and control the volume and toxicity of products in the waste stream and a growing need to shift responsibility to the product manufacturer.
Traditional methods of waste disposal have proven to be ineffective and have caused harmful effects on the environment. The most popular and inexpensive way to get rid of garbage is burial, but burying your problems does not necessarily mean getting rid of them. Landfill sites pose as severe ecological threats as these mass garbage dump yards overflow with trash and frequently contaminate our air, soil and water with hazardous wastes. About 400 million tons of hazardous wastes are generated each year1. A large-scale release of these materials can cause thousands of deaths and may poison the environment for many years. For example many industrial companies around the world cannot afford to enforce the strict pollution regulations set by many developed countries. This usually forces these types of companies to move to developing countries where pollution regulations are very lenient. These developing countries knowingly accept environmentally hazardous companies usually because they are in desperate need of employment. The harmful effects of these companies were clearly illustrated in the 1960s and 1970s when residents living near Minamata Bay, Japan, developed nervous disorders, tremors, and paralysis in a mysterious epidemic. The root was later found to be a local industry that had released mercury, a highly toxic element, into Minamata Bay. The disaster had claimed the lives of 400 people1. Since 1970 you can bet that a lot more than 400 people have died as a result of waste disposal. If the type of waste disposal were cheaper and effective we wouldn’t have to deal with waste problems, which still plague mankind today.
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, ...
