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).
Kansas City
Kansas City is the largest city in Missouri and the sixth largest city in the Midwest. According to the U.S. Census Bureau, the city had an estimated population of 475,378 in 2015,[6] making it the 36th largest city by population in the United States. It is the anchor city of the Kansas City metropolitan area, which straddles the Kansas–Missouri border. Kansas City was founded in the 1830s as a Missouri River port at its confluence with the Kansas River coming in from the west. On June 1, 1850 the town of Kansas was incorporated; shortly after came the establishment of the Kansas Territory. Confusion between the two ensued and the name Kansas City was assigned to distinguish them soon thereafter.
Sitting on Missouri’s western border, with Downtown near the confluence of the Kansas and Missouri rivers, the modern city encompasses some 319.03 square miles (826.3 km2), making it the 23rd largest city by total area in the United States. Most of the city lies within Jackson County, but portions spill into Clay, Cass, and Platte counties. Along with Independence, it serves as one of the two county seats for Jackson County. Major suburbs include the Missouri cities of Independence and Lee’s Summit and the Kansas cities of Overland Park, Olathe, and Kansas City.
The city is composed of several neighborhoods, including the River Market District in the north, the 18th and Vine District in the east, and the Country Club Plaza in the south. Kansas City is also known for its cuisine (including its distinctive style of barbecue), its craft breweries and its major league sports teams.
