MWDA was established in 1986 following the abolition of Merseyside County Council, to undertake the waste disposal for local authorities across Merseyside – Liverpool, Knowsley, Sefton, Wirral and St Helens.  MWDA takes a lead in advocating waste minimisation, recycling and the safe and effective disposal of waste for Merseyside’s residents and operates 14 Household Waste Recycling Centres.  Veolia Environmental Services is the current contractor for the Authority's major waste services contract.

Greater Manchester Waste Disposal Authority: The Greater Manchester Waste Disposal Authority (GMWDA) is England’s largest Waste Disposal Authority, responsible for the management and disposal of municipal waste from Greater Manchester.  It deals with 1.1 million tonnes of waste produced each year, from approximately 1 million households and population of over 2.27 million in the metropolitan districts of Bolton, Bury, Manchester, Oldham, Rochdale, Salford, Stockport, Tameside and Trafford — though part of Greater Manchester, the Metropolitan Borough of Wigan administers its own waste disposal operations, however they are represented on the authority for administration purposes.  The waste comes primarily from household waste collections and 20 Household Waste Recycling Centres (HWRCs) provided and serviced by the GMWDA.  It handles around 4% of the nation's municipal waste.

InSinkErator: InSinkErator is a company and brand name known for producing instant hot water dispensers and waste disposal systems, generally called garbage disposals or garbage disposers.  The company was founded in Racine, Wisconsin by John W. Hammes, who was working as an architect there.  Hammes is credited with inventing the "in-sink" food waste disposal in 1927, for his wife.  It works by grinding and shredding solid food waste.  He spent ten years improving the design and went into business selling the appliance.  His company was called the In-Sink-Erator Manufacturing Company.  The name is a play on the word "incinerator" and refers to the fact that the mouth of the disposal unit is located "in" the "sink".

Waste disposal authority: Waste disposal authorities (WDA) were established in the United Kingdom following the Environmental Protection Act 1990.

In the case of unitary authorities waste disposal authorities are the same as the waste collection authority.  WDAs are responsible for developing and implementing plans to deal with municipal waste.

Junipero Serra Landfill: The Junipero Serra Landfill was a solid waste disposal site in Colma, California, United States.  The site was closed in 1983 and ultimately developed by commercial land uses, collectively known as the Metro Center.  The original commercial use built on the closed landfill site was a Home Depot Inc.retail store and parking lot constructed over 1,348 piles, each driven approximately 160 ft deep into the landfill (Bay Area Rapid Transit District, 2006).  The site also required the engineering of a landfill gas control system, since, when organic solid waste aerobically decomposes, it produces methane gas, which is explosive and toxic in large concentrations.  SCS Engineers was presented an award by the Solid Waste Association of North America for the design of the closure methane capture system at this landfill.  (SCS Engineers, 2002).

It is located in the District of Saanich on top of a hill, between Victoria and Sidney, at the end of Hartland Avenue.  There is a public waste drop-off area, a recycling centre, a household hazardous waste collection facility and an electricity generating station that utilizes landfill gas as a fuel source.
