Waste management 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, economic mechanisms.
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden.
Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas and heat. The ash is mostly formed by the inorganic constituents of the waste and may take the form of solid lumps or particulates carried by the flue gas. The flue gases must be cleaned of gaseous and particulate pollutants before they are dispersed into the atmosphere. In some cases, the heat that is generated by incineration can be used to generate electric power.
Zero waste is a set of principles focused on waste prevention that encourages the redesign of resource life cycles so that all products are reused. The goal is for no trash to be sent to landfills, incinerators or the ocean. Currently, only 9% of plastic is actually recycled. In a zero waste system, material will be reused until the optimum level of consumption. The definition adopted by the Zero Waste International Alliance (ZWIA) is:
Zero Waste: The conservation of all resources by means of responsible production, consumption, reuse and recovery of all products, packaging, and materials, without burning them, and without discharges to land, water or air that threaten the environment or human health.
Pay as you throw (PAYT) is a usage-pricing model for disposing of municipal solid waste. Users are charged a rate based on how much waste they present for collection to the municipality or local authority.
A landfill tax or levy is a form of tax that is applied in some countries to increase the cost of landfill. The tax is typically levied in units of currency per unit of weight or volume. The tax is in addition to the overall cost of landfill and forms a proportion of the gate fee.
In the densely populated Hong Kong, waste is a complex issue. The territory generates around 6.4 million tons of waste each year but is able to collect and process only a minimal portion of recyclable waste. By 2019, its existing landfills are expected to be full. The government has introduced waste management schemes and is working to educate the public on the subject. On the commercial side, producers are taking up measures to reduce waste.
Waste management in Japan today emphasizes not just the efficient and sanitary collection of waste, but also reduction in waste produced and recycling of waste when possible. This has been influenced by its history, particularly periods of significant economic expansion, as well as its geography as a mountainous country with limited space for landfills. Important forms of waste disposal include incineration, recycling and, to a smaller extent, landfills and land reclamation. Although Japan has made process since the 1990s in reducing waste produced and encouraging recycling, there is still further progress to be made in reducing reliance on incinerators and the garbage sent to landfills. Challenges also exist in the processing of electronic waste and debris left after natural disasters.
Waste are unwanted or unusable materials. Waste is any substance which is discarded after primary use, or is worthless, defective and of no use. A by-product by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.
Municipal solid waste (MSW) – more commonly known as trash or garbage – consists of everyday items people use and then throw away, such as product packaging, grass clippings, furniture, clothing, bottles, food scraps and papers. In 2018, Americans generated about 292.4 million short tons (265.3 Mt) of trash. In the United States, landfills are regulated by the Environmental Protection Agency (EPA) and the states' environmental agencies. Municipal solid waste landfills (MSWLF) are required to be designed to protect the environment from contaminants that may be present in the solid waste stream.
Waste Concern is a Bangladesh Social Business Enterprise (SBE) for waste recycling.
Waste management in Russia refers to the legislation, actions and processes pertaining to the management of the various waste types encountered throughout the Russian Federation. The basis of legal governance for waste management in Russia at the federal level is outlined through Federal Law No. 89-FZ, which defines waste as “the remains of raw materials, materials, semi-finished products, other articles or products that have been formed in the process of production or consumption as well as the goods (products) that have lost their consumer properties”.
It is estimated that 290 million tonnes of waste was produced in the United Kingdom in 2008 but volumes are declining. In 2012 municipal solid waste generation was almost 30 million tonnes, according to Waste Atlas Platform.
Statistical data shows that waste management in Winnipeg during the COVID-19 Pandemic.
Waste Atlas is an interactive waste management map that visualises global solid waste management data for comparison and benchmarking purposes.
Turkey generates 28,858,880 tons of solid municipal waste per year; the annual amount of waste generated per capita amounts to 390 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.
Waste management in India falls under the purview of the Union Ministry of Environment, Forests and Climate Change (MoEF&CC). In 2016, this ministry released the Solid Wastage Management (SWM) Rules, which replaced by the Municipal Solid Waste Rules, and 2000 of which had been in place for 16 years. This national policy plays a significant role in the acknowledgement and inclusion of the informal sector into the waste management process for the first time.
Data from the Solid Waste Management and Public Cleansing Corporation (SWCorp) collected from January to November throughout 2018 puts the national recycling rate at 0.06%, or about 1,800 tonnes of the 3 million tonnes of waste collected in the period. Majority of the waste were sent to landfills.
Waste management in South Korea involves waste generation reduction and ensuring maximum recycling of the waste. This includes the appropriate treatment, transport, and disposal of the collected waste. South Korea's Waste Management Law was established in 1986, replacing the Environmental Protection Law (1963) and the Filth and Cleaning Law (1973). This new law aimed to reduce general waste under the waste hierarchy in South Korea. This Waste Management Law imposed a volume-based waste fee system, effective for waste produced by both household and industrial activities.
In Egypt, waste and lack of proper management of it pose serious health and environmental problems for the country and its population. There has been some governmental attempts to better the system of waste management since the 1960s but those have not proven sufficient until now. In the last 10 years focus on this issue and solutions to it has increased both from the government and civil society. Some attempts at recycling are present, and growing in the country. But these are largely informal or private actors, and government initiatives are necessary to properly manage these systems and provide them with appropriate resources.
