Waste management in Bangladesh faces many challenges due to its large, rapidly growing population in a densely populated country.
Bangladesh is the ninth most populous and twelfth most densely populated country in the world. In particular, the projected urban population growth rate from 2010 to 2015 is 3%. [1] With this population growth, there is an increasing problem of waste management particularly in the larger cities. Currently, according to an UNFPA report, Dhaka is one of the most polluted cities in the world and one of the issues concerned is the management of municipal waste. As for solid waste like paper, carton, metal, plastics, Pet Bottles, e-waste, there was no initiatives to ensure environment friendly recycling. But from 2018 there is a local startup named BD Recycle (www.bdrecycle.com) working to digitalized and organize solid waste recycling. BD Recycle have a webapp and Android app to buy waste from corporates, households, and factories. BD Recycle collect waste, then sort waste and send to factory end recycler who ensure sustainable recycling. [2]
Current (2012) waste generation in Bangladesh is around 22.4 million tonnes per year or 150 kg/cap/year. [3] There is an increasing rate of waste generation in Bangladesh and it is projected to reach 47, 064 tonnes per day by 2025. The rate of waste generation is expected to increase to 220 kg/cap/year in 2025. A significant percentage of the population has zero access to proper waste disposal services, which will in effect lead to the problem of waste mismanagement. [4]
The total waste collection rate in major cities of Bangladesh such as Dhaka is only 37%. When waste is not properly collected, it will be illegally disposed of and this will pose serious environmental and health hazards to the Bangladeshis. [5]
One of the most adverse impacts of poor waste management, especially municipal waste, is the incidence and prevalence of diseases such as malaria and respiratory problems, as well as other illnesses through the contamination of ground water. Biomedical wastes pose great danger in Bangladesh too as a report estimated that 20% of the biomedical waste is "highly infectious" and is a hazard since it is often disposed of into the sewage system or drains. [6] Such poor sanitation has serious consequences for the health of the residents and a report suggests that "most of the child mortality could be related with this problem". [7] With regards to the living standards, solid waste leads to blockage in the drainage system which leads to flooding in the streets. Consequently, mosquitoes and bad odour are among the negative impacts resulted. [7]
Landfills in most countries including in Bangladesh contribute to methane emissions which accelerates climate change. The Matuail Sanitary Landfill releases methane emissions equivalent to 190,000 cars. [8]
There have been recent developments in Bangladesh to improve waste management, especially in urban cities. In Dhaka, Dhaka City Corporation with support from the Japan International Corporation Agency (JICA) has a master plan underway to better handle the solid waste management in Dhaka. [9] For example, Social Business Enterprise Waste Concern, has sprung up to tackle the municipal waste accumulation problem through working with the households. UNICEF has also initiated recycling programs and waste control with the city corporations and municipalities. [9] However, currently, there are still insufficient incentives to improve the standard of waste management across all relevant sectors, especially for industrial waste and medical waste.
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.
A landfill is a site for the disposal of waste materials. It is the oldest and most common form of waste disposal, although the systematic burial of waste with daily, intermediate and final covers only began in the 1940s. In the past, waste was simply left in piles or thrown into pits.
Municipal solid waste (MSW), commonly known as trash or garbage in the United States and rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog. Although the waste may originate from a number of sources that has nothing to do with a municipality, the traditional role of municipalities in collecting and managing these kinds of waste have produced the particular etymology 'municipal.'
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 progress 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 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 265.3 million tonnes of waste. 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 Bangladeshi Social Business Enterprise (S.B.E) 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.

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.
Waste management in India falls under the purview of the Union Ministry of Environment, Forest 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 acknowledgment 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 e 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.
The Sfax Waste To Methane Gas Project is a proposed plant to convert solid waste into methane gas, by the facilitation of anaerobic digestion of organic waste in a new plant in Sfax, Tunisia's second-largest city. The estimated 1,900,000 cubic meters (1.9×109 L) of methane from the future waste-to-energy plant is expected to fuel a fleet of 800 automobile taxis every year. The project is a joint venture of four Tunisian government entities; (a) the City of Sfax (COS) (b) the National Oil Distribution Company (AGIL) (c) the National Agency for Energy Management (ANME) and the Commissariat à l’énergie atomique et aux énergies alternatives (CEA-PRO).
