Examples of biodegradble things are paper, cotton, human and solid waste. When disposed, biodegradable materials are broken down by microorganisms and other living things in a reasonable time period.
When composted correctly, a banana peel can decompose in two days. In inadequate environment, the biodegration of a banana can take up to three years. In an unmanaged landfill, newspapers take 25 to 40 years to decompose, office paper takes 29 to 46 years, food waste takes from five to 10 years, wood can take 58 to 99 years, and cotton can take from 29 to 46 years to decompose. Biodegration takes twice as long in a dry environment as it does in a moderately wet environment. In a bioreactor environment, or a managed landfill environment which accelerates biodegration, these time frames are cut to up to 25 percent.
Some plastics are made to biodegrade by adding cornstarch or vegetable oil to speed up the process. However, unless the plastic is disposed of in a specific environment and at an ideal humidity level, the process of biodegration may take the same amount of time to biodegrade as a nonbiodegradable piece of plastic.
Items like plastic bags, tin cans, computer hardware, synthetic material and Styrofoam are not biodegradable. Most of these products take more than 500 years to degrade, if they degrade at all.Learn More
The U.S. Energy Information Administration estimates that the natural gas reserves of the United States will last around 92 years. The estimate will hold true only if the national natural gas consumption rate stays at the 2011 levels, around 24 trillion cubic feet per year.Full Answer >

Proximate analysis reveals the quality and precise chemical composition of a coal sample. This analysis examines four factors: moisture, volatile compounds, ash content and fixed carbon. Information revealed during proximate analysis impacts coal prices and determines the most efficient use for each shipment.Full Answer >
Maize, otherwise known as corn, is important to the economy due to its wide range of uses. Maize is primarily used as feed for livestock, suggesting the dependence of the livestock industry on corn production. It is also used to create a variety of food and nonfood products, such as corn meal, sweeteners, corn oil, starch and ethanol, which is used as a cleaner-burning alternative to gasoline.Full Answer >
