Investigation Part 3: Composting

The U.S. Environmental Protection Agency ranks methods of handling food waste in the diagram below:

Composting is listed as the second least preferred method of reducing the environmental impact of food waste. Nonetheless, it will be explored in this portion of the investigation.

Background Information

All organic material – such as orange and banana peels and apple cores that come from Stuart’s cafeteria – will eventually decompose, but composting is a human-monitored activity that speeds up the process of decomposition. It involves combining “green”, nitrogen-rich materials, such as fruit and vegetable scraps, with “brown”, carbon-rich materials, such as twigs and dead leaves. When combined in …show more content…

The “parts”, or inputs, required to compost are a container or designated area (to be discussed later), green material, brown material, human monitoring, and time. When these parts are combined to create an “entirety”, they relate in such a way that the system “functions” to create a soil-like substance.

Environmental Benefits

The most practical use of compost is to combine it with actual soil and use it as a plant growth medium. Composting is immersed by environmental benefits, whether the benefits are applicable during the composting process or applicable when the compost is used to support plant growth.

• While greens and browns transform into compost, microorganism break down molecules. These molecules provide food for larger organisms, such as fungi and worms. In turn, these organisms attract even larger predators, such as birds. Compost piles create a miniature ecosystem packed with thriving organisms of numerous types and sizes.

• The crumb-like structure of compost allows it to store or release air and water depending on the plant’s needs. Also, the fact that compost provides air and water through plants’ roots reduces the need for plants to obtain air and water from the atmosphere. Furthermore, compost’s ability to store over 60% of its own mass in water reduces the need for plants to be watered and improves their chances of surviving through droughts.

• Compost is an
