Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.
Zero waste, or waste minimization, is a set of principles focused on waste prevention that encourages redesigning Natural resource resource life cycles so that all products are repurposed and/or reused. The goal of the movement is to avoid sending trash to landfills, incinerators, oceans, or any other part of the environment. Currently 9% of global Plastic recycling plastic is recycled. In a zero waste system, all materials are reused until the optimum level of consumption is reached.
Waste (management) hierarchy is a tool used in the evaluation of processes that protect the environment alongside resource and energy consumption from most favourable to least favourable actions. The hierarchy establishes preferred program priorities based on sustainability. To be sustainable, waste management cannot be solved only with technical end-of-pipe solutions and an integrated approach is necessary.
The Greater Manchester Waste Disposal Authority (GMWDA) was England's largest waste disposal authority, responsible for the management and disposal of municipal waste from Greater Manchester. It dealt with 1.1 million tonnes of waste produced each year, from approximately 1 million households and a 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 were represented on the authority for administration purposes. The waste came primarily from household waste collections and 20 household waste recycling centres (HWRCs) provided and serviced by the GMWDA. It handled around 4% of the nation's municipal waste.
Landfills in the United Kingdom were historically the most commonly used option for waste disposal. Up until the 1980s, policies of successive governments had endorsed the "dilute and disperse" approach. Britain has since adopted the appropriate European legislation and landfill sites are generally operated as full containment facilities. However, many dilute and disperse sites remain throughout Britain.
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes. It mainly includes kitchen waste, ash, soil, dung and other plant matter. In waste management, it also includes some inorganic materials which can be decomposed by bacteria. Such materials include gypsum and its products such as plasterboard and other simple sulfates which can be decomposed by sulfate reducing bacteria to yield hydrogen sulfide in anaerobic land-fill conditions.
This article outlines the position and trends of recycling in Canada. Since the 1980s, most mid to large municipalities in most provinces have recycling programs, relying on curbside collection with either bins, boxes, or bags. These systems are not standardized, and the specific process differs for each province. Certain provinces have container-deposit systems in place for bottles, cans, and other beverage containers.
Rates of household recycling in Ireland have increased dramatically since the late 1990s. The Irish Environmental Protection Agency (EPA) is the agency with overall responsibility for environmental protection in Ireland and monitors rates of recycling in Ireland along with other measures of environmental conditions in Ireland. The EPA, along with Repak, the principal organisation for packaging recycling in Ireland, report on recycling rates each year. In 2012 Ireland’s municipal solid waste (MSW) recycling rate was 34%, while the rate of packaging recycling reached 79%. The amount of municipal waste generated per person per year in Ireland has fallen significantly in recent years. This figure remains above the European Union annual municipal waste average of 503 kg per person, however. Each local council in Ireland has considerable control over recycling, so recycling practices vary to some extent across the country. Most waste that is not recycled is disposed of in landfill sites.
In 2015, 43.5% of the United Kingdom's municipal waste was recycled, composted or broken down by anaerobic digestion. The majority of recycling undertaken in the United Kingdom is done by statutory authorities, although commercial and industrial waste is chiefly processed by private companies. Local Authorities are responsible for the collection of municipal waste and operate contracts which are usually kerbside collection schemes. The Household Waste Recycling Act 2003 required local authorities in England to provide every household with a separate collection of at least two types of recyclable materials by 2010. Recycling policy is devolved to the administrations of Scotland, Northern Ireland and Wales who set their own targets, but all statistics are reported to Eurostat.
ARC21 is a local government body that is tasked with coordination of the waste management and recycling services in the North East of Northern Ireland.
Before disbanding in 2015, the Southern Waste Management Partnership (SWaMP) coordinated the disposal and handling of municipal waste, including recycling, in the South of Northern Ireland. The local authorities that were covered by SWaMP included:
- Armagh City and District Council
- Banbridge District Council
- Cookstown District Council
- Craigavon Borough Council
- Dungannon and South Tyrone Borough Council
- Fermanagh District Council
- Newry and Mourne District Council
The National Waste Strategy is a policy of the Parliament of the United Kingdom as well as the devolved administrations in Scotland, Wales and Northern Ireland. The development of national waste strategies is intended to foster a move to sustainability in waste management within the United Kingdom.
The management of waste in New Zealand has become more regulated to reduce associated environmental issues. According to OECD data, New Zealand is the third most wasteful country in the OECD.
Waste management in Bangladesh faces many challenges due to its large, rapidly growing population in a densely populated country.
Statistical data shows that waste management in Winnipeg during the COVID-19 Pandemic.
Turkey generates about 30 million tons of solid municipal waste per year; the annual amount of waste generated per capita amounts to about 400 kilograms. According to Waste Atlas, Turkey's waste collection coverage rate is 77%, whereas its unsound waste disposal rate is 69%. While the country has a strong legal framework in terms of laying down common provisions for waste management, the implementation process has been considered slow since the beginning of 1990s.
Food waste recycling is a process to convert food waste into useful materials and products for achieving sustainability of the environment. Food waste is defined as all parts of food, inedible and edible, created before, during, and after food processing, production, and consumption. Greenhouse gases, especially methane can be reduced by food waste recycling. Food waste recycling can also alleviate the saturation of landfill sites in Hong Kong.
Recycling in Australia is a widespread, and comprehensive part of waste management in Australia, with 60% of all waste collected being recycled. Recycling is collected from households, commercial businesses, industries and construction. Despite its prominence, household recycling makes up only a small part (13%) of Australia's total recycling. It generally occurs through kerbside recycling collections such as the commingled recycling bin and food/garden organics recycling bin, drop-off and take-back programs, and various other schemes. Collection and management of household recycling typically falls to local councils, with private contractors collecting commercial, industrial and construction recycling. In addition to local council regulations, legislation and overarching policies are implemented and managed by the state and federal governments.
Waste management in Australia started to be implemented as a modern system by the second half of the 19th century, with its progresses driven by technological and sanitary advances. It is currently regulated at both federal and state level. The Commonwealth's Department of the Environment and Energy is responsible for the national legislative framework.
