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).
Huntingdon
Huntingdon is a borough in (and the county seat of) Huntingdon County, Pennsylvania, United States. It is located along the Juniata River, approximately 32 miles (51 km) east of Altoona and 98 miles (158 km) west of Harrisburg. It is the largest population center near Raystown Lake, a winding, 28 miles (45 km) long flood-control reservoir managed by the U. S. Army Corps of Engineers. The borough is located on the main line of the Norfolk Southern (formerly Pennsylvania) Railroad, in an agricultural and outdoor recreational region with extensive forests and scattered deposits of ganister rock, coal, fire clay, and limestone. Historically, the region surrounding Huntingdon was dotted with iron furnaces and forges, consuming limestone, iron ore and wood (for charcoal production) throughout the 19th century. Dairy farms dominate the local agriculture. The town is a regular stop for the Amtrak passenger service which connects Harrisburg with Pittsburgh.
Huntingdon is home to Juniata College, a private liberal arts college founded by members of the Church of the Brethren in 1876, and branch campuses of DuBois Business College and Penn Highlands Community College. In adjoining Smithfield Township (across the Juniata River) are the regional headquarters of the Pennsylvania Game Commission (Southcentral Division) and the Bureau of Forestry (Rothrock State Forest). State Game Lands 322 extends north from Huntingdon Borough in the direction of Petersburg. Public parks are the George N. Weaver Memorial Park (ball field and playground) at the end of 16th Street, Portstown Park along the Juniata River, and Blair Field bordering Standing Stone Creek. Historic Blair Park, directly across the same stream, is owned and managed by a nonprofit group; it contains a gazebo, and a level hiking and biking trail. A vintage chapel within the park is used by the congregation of Epiphany of Our Lord Orthodox Church.
