he challenge of waste disposal has becoming increasingly difficult since the industrial revolution. With increasing population, urbanization, and prosperity, modern society engages in mass production and mass consumption. As a result there is considerable waste generated which has far reaching affects. Many nations are examining options to lessen the amount of waste generated, and how to manage that waste.

Per capita the world’s largest consumer, the United States produces a quarter of the world’s waste. The waste that people dispose of in their garbage is referred to as Municipal Solid Waste. This is primarily household waste that is sometimes called urban solid waste. There are other types of waste including medical, air-borne, liquid, …show more content…

It releases poisonous gases and toxins (e.g. dioxin) directly into the environment which are harmful to humans and animals.

Composting
Composting is used as a means of managing organic household waste, E.g. branches and leaves. This benefits the environment as it reduces the formation of gases in landfills and helps replenish the soil. Over the past few years, many U.S. cities like Portland, Seattle, and San Francisco have added composting to their waste management solutions, and have started offering curbside pickup. …show more content…

The remains are then buried inside the earth in landfills. Research has shown the gases produced during the process of incineration are extremely toxic and much more dangerous than the original waste material. Due to public opposition to this method of waste management, no new incinerators have been built after 1997. Pyrolysis is similar to incineration, but the solid waste is burned without oxygen.

Gasification
This technology involves using oxygen to convert waste containing carbon into gases (syngas), both combustible and non-combustible. The resulting gas is used to produce heat energy and leftover waste ends up in landfills. Landfill space is reduced and usable energy is produced from the waste. Out of 140 plants worldwide, 19 gasification plants are located in the United States.

Landfills
Landfills are areas where large amounts of waste is accumulated and eventually buried. There are even parks built on top of landfills. However, without proper management landfills can have a harmful effect on the environment. When the solid waste inside the landfill degrades, it releases gases including methane and carbon dioxide. These gases penetrate through the soil and pollute the surrounding air. Landfills that are not properly sealed and capped are also a risk. Rain water can seep into the solid waste, leading to the formation of leachate, a toxic liquid. Water contamination occurs
