Main article: Recycling
Recycling is a resource recovery
practice that refers to the collection and reuse of waste materials
such as empty beverage containers. The materials from which the items
are made can be reprocessed into new products. Material for recycling
may be collected separately from general waste using dedicated bins and
collection vehicles, a procedure called kerbside collection.
In some communities, the owner of the waste is required to separate the
materials into various different bins (e.g. for paper, plastics,
metals) prior to its collection. In other communities, all recyclable
materials are placed in a single bin for collection, and the sorting is
handled later at a central facility. The latter method is known as "single-stream recycling."[10][11]
The most common consumer products recycled include aluminium such as beverage cans, copper such as wire, steel from food and aerosol cans, old steel furnishings or equipment, polyethylene and PET bottles, glass bottles and jars, paperboard cartons, newspapers, magazines and light paper, and corrugated fiberboard boxes.
PVC, LDPE, PP, and PS (see resin identification code)
are also recyclable. These items are usually composed of a single type
of material, making them relatively easy to recycle into new products.
The recycling of complex products (such as computers and electronic
equipment) is more difficult, due to the additional dismantling and
separation required.
The type of material accepted for recycling varies by city and
country. Each city and country has different recycling programs in place
that can handle the various types of recyclable materials. However,
certain variation in acceptance is reflected in the resale value of the
material once it is reprocessed.
