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).
Guthrie
Guthrie is a city and county seat in Logan County, Oklahoma, United States, and a part of the Oklahoma City Metroplex. The population was 10,191 at the 2010 census, a 2.7 percent increase from the 9,925 at the 2000 census.[5]
First known as a railroad station stop, after the April 1889 land run, Guthrie immediately gained 10,000 new residents who began to develop the town. It was rapidly improved and was designated as the territorial capital, and in 1907 as the first state capital of Oklahoma. In 1910 state voters chose the larger Oklahoma City as the new capital in a special election.
Guthrie is nationally significant for its collection of late 19th and early 20th century commercial architecture. The Guthrie Historic District includes more than 2,000 buildings and is designated as a National Historic Landmark. Historic tourism is important to the city, and its Victorian architecture provides a backdrop for Wild West and territorial-style entertainment, carriage tours, replica trolley cars, specialty shops, and art galleries.
