Recycling
Recycling is the process of converting waste materials into new materials and objects. It is an alternative to “conventional” waste disposal that can save material and help lower greenhouse gas emissions. Recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing: energy usage, air pollution (from incineration), and water pollution (from landfilling).
Recycling is a key component of modern waste reduction and is the third component of the “Reduce, Reuse, and Recycle” waste hierarchy.[1][2] Thus, recycling aims at environmental sustainability by substituting raw material inputs into and redirecting waste outputs out of the economic system.[3]
There are some ISO standards related to recycling such as ISO 15270:2008 for plastics waste and ISO 14001:2015 for environmental management control of recycling practice.
Recyclable materials include many kinds of glass, paper, cardboard, metal, plastic, tires, textiles, batteries, and electronics. The composting or other reuse of biodegradable waste—such as food or garden waste—is also a form of recycling.[4] Materials to be recycled are either delivered to a household recycling center or picked up from curbside bins, then sorted, cleaned, and reprocessed into new materials destined for manufacturing new products.
In the strictest sense, recycling of a material would produce a fresh supply of the same material—for example, used office paper would be converted into new office paper or used polystyrene foam into new polystyrene. However, this is often difficult or too expensive (compared with producing the same product from raw materials or other sources), so “recycling” of many products or materials involves their reuse in producing different materials (for example, paperboard) instead. Another form of recycling is the salvage of certain materials from complex products, either due to their intrinsic value (such as lead from car batteries, or gold from printed circuit boards), or due to their hazardous nature (e.g., removal and reuse of mercury from thermometers and thermostats).
Murfreesboro
Murfreesboro is a city in and the county seat of Rutherford County, Tennessee.[7] The population was 108,755 according to the 2010 census, up from 68,816 residents certified in 2000. In 2015, census estimates showed a population of 126,118.[5]The city is the center of population of Tennessee[8] and is part of the Nashville metropolitan area, which includes thirteen counties and a population of 1,757,912 (2013). It is Tennessee’s fastest growing major city and one of the fastest growing cities in the country.[9] Murfreesboro is also home to Middle Tennessee State University, the largest undergraduate university in the state of Tennessee, with 22,729 total students as of fall 2014.[10]
In 2006, Murfreesboro was ranked by Money as the 84th best place to live in the United States, out of 745 cities with a population over 50,000.[11][12]
In 1811, the Tennessee State Legislature established a county seat for Rutherford County. The town was first named “Cannonsburgh” in honor of Newton Cannon, then Rutherford County’s member of the state legislature, but it was soon renamed “Murfreesboro” for Revolutionary War hero Colonel Hardy Murfree.[13] Author Mary Noailles Murfree was his great-granddaughter.
As Tennessee settlement expanded to the west, the location of the state capital in Knoxville became inconvenient for most newcomers. In 1818, Murfreesboro was designated as the capital of Tennessee. Eight years later, however, it was itself replaced by Nashville.[14]
