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).
Waco
Waco (/ˈweɪkoʊ/ way-koh) is a city which is the county seat of McLennan County, Texas, United States.[3] It is situated along the Brazos River and I-35, halfway between Dallas and Austin. The city had a 2010 population of 124,805, making it the 22nd-most populous city in the state.[4] The US Census 2015 population estimate is 132,356.[5] The Waco Metropolitan Statistical Area consists of McLennan and Falls Counties, which had a 2010 population of 234,906.[6] Falls County was added to the Waco MSA in 2013. The US Census 2016 population estimate for the Waco MSA is 265,207.[7]
Indigenous peoples occupied areas along the river for thousands of years. In historic times, the area of present-day Waco was occupied by the Wichita Indian tribe known as the “Waco” (Spanish: Hueco or Huaco).
In 1824, Thomas M. Duke was sent to explore the area after the Waco people tried to defend themselves and their lands from settlers. His report to Stephen F. Austin, described the Waco village:
After further violence due to settler incursion, Austin halted an attempt to destroy their village in retaliation. In 1825, he made a treaty with them. The Waco were eventually pushed out of the region, settling north near present-day Fort Worth. In 1872, they were forced onto a reservation in Oklahoma with other Wichita tribes. In 1902, the Waco received allotments of land and became official US citizens. Neil McLennan settled in an area near the South Bosque River in 1838.[8] Jacob De Cordovabought McLennan’s property[9] and hired a former Texas Ranger and surveyor named George B. Erath to inspect the area.[10]In 1849, Erath designed the first block of the city. Property owners wanted to name the city Lamartine, but Erath convinced them to name the area Waco Village, after the Indians who had lived there.[11] In March 1849, Shapley Ross built the first house in Waco, a double-log cabin, on a bluff overlooking the springs. His daughter Kate was the first settler child to be born in Waco.[12]
