A landfill site, also known as a tip, dump, rubbish dump, garbage dump, trash 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.
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.'
Environmental Protection Department (EPD) is a department of Hong Kong Government concerning the issues of environmental protection in Hong Kong.The EPD is responsible for developing policies covering environmental protection, nature conservation; enforcing environmental legislation; monitoring environmental quality; providing collection, transfer, treatment and disposal facilities for many types of waste; advising on the environmental implications of town planning and new policies; handling pollution complaints and incidents; and raising awareness and support in the community for environmental initiatives.

Landfills are the primary method of waste disposal in many parts of the world, including United States and Canada. Bioreactor landfills are expected to reduce the amount of and costs associated with management of leachate, to increase the rate of production of methane for commercial purposes and reduce the amount of land required for land-fills. Bioreactor landfills are monitored and manipulate oxygen and moisture levels to increase the rate of decomposition by microbial activity.
Landfill mining and reclamation (LFMR) is a process which excavates and processes solid wastes which have previously been landfilled. The process aims to reduce the amount of landfill mass encapsulated within the closed landfill and/or temporarily remove hazardous material to allow protective measures to be taken before the landfill mass is replaced. In the process, mining recovers valuable recyclable materials, a combustible fraction, soil, and landfill space. The aeration of the landfill soil is a secondary benefit with regard to the landfill's future use. The combustible fraction is useful for power generation. The overall appearance of the landfill mining procedure is a sequence of processing machines laid out in a functional conveyor system. The operating principle is to excavate, sieve and sort the landfill material.
Construction waste or debris is any kind of debris from the construction process. Different government agencies have clear definitions. For example, the United States Environmental Protection Agency EPA defines construction and demolition materials as “debris generated during the construction, renovation and demolition of buildings, roads, and bridges.” Additionally, the EPA has categorized Construction and Demolition (C&D) waste into three categories: non-dangerous, hazardous, and semi-hazardous.

Sai Tso Wan Recreation Ground is a multi-purpose playground in Sai Tso Wan, Kwun Tong District, in eastern Kowloon, Hong Kong. It is the first permanent recreational facility built on a landfill in the city.
Air pollution in Hong Kong is considered a serious problem. In 2004, visibility was less than eight kilometers for 30 per cent of the year. Cases of asthma and bronchial infections have soared due to reduced air quality. However, in recent years, the hours of reduced visibility in Hong Kong have decreased by significant amounts compared to the previous ten years.
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.
Landfill gas utilization is a process of gathering, processing, and treating the methane or another gas emitted from decomposing garbage to produce electricity, heat, fuels, and various chemical compounds. After fossil fuel and agriculture, landfill gas is the third largest human generated source of methane. Compared to CO2, methane is 25 times more potent as a greenhouse gas. It is important not only to control its emission but, where conditions allow, use it to generate energy, thus offsetting the contribution of two major sources of greenhouse gases towards climate change. The number of landfill gas projects, which convert the gas into power, went from 399 in 2005 to 519 in 2009 in the United States, according to the US Environmental Protection Agency. These projects are popular because they control energy costs and reduce greenhouse gas emissions. These projects collect the methane gas and treat it, so it can be used for electricity or upgraded to pipeline-grade gas. These projects power homes, buildings, and vehicles.
Source-separated organics (SSO) is the system by which waste generators segregate compostable materials from other waste streams at the source for separate collection.

He has contributed to the promotion and research of the standards and guidelines for sustainable built environment applicable to the high-density urban environment of Hong Kong.
Atlantic County Utilities Authority (ACUA) is a public agency in Atlantic County, New Jersey, that is responsible for enhancing quality of life through the protection of waters and lands from pollution by providing responsible waste management services.
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.
In Hong Kong, domestic waste has always been the largest portion of municipal solid waste. In 2014, domestic waste constitutes 65% of municipal solid waste, and 43% of total solid waste at landfills. Hong Kong has the highest daily domestic waste generation rates per capita compared to other metropolitans in Asia: Metro Tokyo creates 0.77 kg per day per capita, Seoul generates 0.95 kg, Taipei City produces 1.00 kg and Hong Kong tops the rank by 1.36 kg.
The Hong Kong plastic shopping bag environmental levy scheme is an environmental levy scheme designed to reduce the manufacture and distribution of plastic shopping bags (PSBs) in Hong Kong. PSBs are made of materials that are not easily degradable. The extensive disposal of PSBs is putting stringent pressure on the very limited landfill capacity, thereby causing severe waste problems in Hong Kong.
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.
Environment and Ecology Bureau is one of the fifteen policy bureaux of the Government of Hong Kong. The agency was established on 1 July 2022. The current Secretary for Environment and Ecology is Tse Chin-wan.
