- Kerbside collection
Kerbside collection (UK) or curbside recycling (elsewhere) is a service provided to households, typically in urban and suburban areas, of removing household waste. It is usually accomplished by personnel using purpose built vehicles to pick up household waste in containers acceptable to or prescribed by the municipality.
Prior to the twentieth century the amount of waste generated by a household was relatively small. Household wastes were often simply thrown out the window, buried in the garden or deposited in outhouses (see more at
urban archaeology). When human concentrations became more dense, waste collectors, called nightmen or gong farmers were hired to collect the night soil, performing their duties only at night (hence the name). Meanwhile, as cities developed, disposing of refuse became a problem. In 1830’s Manhattan, for example, thousands of hogs were permitted to roam the streets and eat garbage. A small industry developed as “swill children” collected kitchen refuse to sell for pig feed, and the rag and bone mantraded goods for bones (used for glue) and rags (essential for paper prior to the invention of wood pulping). [Susan Strasser, "Waste and Want: A Social History of Trash", 1999, New York: Metropolitan Books]
As sanitation engineering came to be practiced beginning in the mid-nineteenth century and human waste was conveyed from the home in pipes, the gong farmer was replaced by the trash collector as there remained growing amounts of household refuse, including coal ash which was a primary form of home heating in the nineteenth century.
By the early part of the twentieth century economies prospered and manufacturers began to introduce package goods. As refuse began to clog city streets, municipalities began to pass anti-dumping ordinances and introduce kerbside collection. Residents used a variety of refuse containers to facilitate kerbside collection but the main type was the metal garbage can. It was not until the late 1960’s that the green
bin bagwas introduced by Glad. Later, as waste managementpractices were introduced with the aim of reducing landfillimpacts, a range of container types came to be introduced to facilitate the proper diversion of the waste stream. Such containers include blue boxes, green bins, and Wheelie bins or MGBs. Over time, waste collection vehicles gradually increased in size from the hand pushed English dust cart, a name by which these vehicles are still referred, to large compactor trucks.
Waste management and resource recovery
Kerbside collection is today often referred to as a strategy of local authorities to collect recyclable items from the consumer. Kerbside collection is considered a low risk strategy to reduce waste volumes and increase recycling rates. Materials are typically collected in large bins, colored bags, or small open plastic tubs, specifically designated for content.

Kerbside collection of recyclable resources is aimed to recover purer waste streams with higher market value than by other collection methods. If the household incorrectly separates the recyclable elements they load may have to be put to
landfillif it is deemed to be contaminated.
Kerbside collection and household recycling schemes are also being used as tools by local authorities to increase the public's awareness of their waste production.
Kerbside collection is commonly considered to be completely environmentally friendly. This may not necessarily be the case as it leads to an increased number of waste collection vehicles on the road, contributing to global warming through exhaust emissions. fact|date=March 2008
New and emerging waste treatment technologies such as
mechanical biological treatmentmay offer an alternative to kerbside collection through automated separation of waste in recycling factories.fact|date=March 2008

Canadauses " green bins" for kerbside recycling
By 1996 the
New Zealandcities of Auckland, Waitakere, North Shore and Lower Hutt had kerbside recycling bins available. In New Plymouth, Wanganui and Upper Hutt recyclable material was collected if placed in suitable bags. [cite web

Kerbside collection of organic waste is carried out by the Mackenzie District Council [http://www.mfe.govt.nz/publications/waste/kerbside-collection-may05/html/page7.html Options for Kerbside Collection of Household Organic Wastes - Appendix 1: Kerbside Kitchen Waste Collections in New Zealand [Ministry for the Environment ] ] and the Timaru District Council. Other councils are carrying out trials.
United Kingdom, the "Household Waste Recycling Act" (2003) will require local authorities to provide every household with a separate collection of at least two types of recyclable materials by 2010. [http://www.foe.co.uk/campaigns/waste/news/recycling_bill_success.html, Friends of the Earth.]
