What is waste management?
Waste management includes all activities and actions required to manage waste from its source to its final disposal. It encompasses the collection, transport, treatment, and disposal of waste. Municipal solid waste is commonly known as everyday garbage and trash produced by households, commercial, and institutional entities.#N#MSW generation in the U.S.#N#The United States accounts for roughly four percent of the global population, but it is responsible for 12 percent of global municipal solid waste generation. In 2018, the total generation of MSW in the U.S. reached a high of 292 million tons, which equated to 4.9 pounds of MSW per capita per day. Increased population and urbanization - in addition to a rising throw-away culture influenced by consumerism - has seen U.S. waste generation increase dramatically over the years, growing by 40 percent since 1990. Paper and paperboard products represent the largest share of all waste materials that enter the U.S. MSW stream, and has done for many decades. This is followed by food waste, which has been increasing more and more in recent years. It is estimated that the average U.S. household produces 19.36 metric tons of food waste per year, which is one of the highest amounts worldwide.#N#MSW disposal methods#N#With such vast quantities of waste generated each year, proper waste disposal is needed to keep environments clean and protect our health. There are a number of waste disposal methods available in the U.S, including landfilling, incineration, and recycling. Recycling in the U.S. has increased considerably since it first began in the 1960, and as of 2018 accounted for approximately 24 percent of MSW disposals. Despite the increased use of recycling to deal with waste, landfilling is still the main treatment method in the country, and accounts for 50 percent of disposals. Of the 146 million tons of landfilled MSW in 2018, a quarter was food waste. There are currently more than 1,200 MSW landfill sites in the U.S. 26 percent of managed landfill volume in the U.S. is managed by Waste Management Inc – the largest U.S. waste management company.#N#This text provides general information.

Why is proper waste disposal important?
With such vast quantities of waste generated each year, proper waste disposal is needed to keep environments clean and protect our health. There are a number of waste disposal methods available in the U.S, including landfilling, incineration, and recycling.
How much MSW is generated in the US?
In 2018, the total generation of MSW in the U.S. reached a high of 292 million tons, which equated to 4.9 pounds of MSW per capita per day.
Why is municipal solid waste management important?
Municipal solid waste management is an important environmental concern around the word. Solid wastes are constantly produced in mega-cities, small towns and large villages, and if residues do not receive the right management, they can cause several affections on the environment and human health. These affections include greenhouse gases emissions, soil contamination, bad odours, underwater contamination, and spread of diseases, among others. Commonly, the treatment of MSW is not carried out because this requires a substantial proportion of government budget without any economic remuneration. Due to most of the projects for MSWM depend on the stakeholders interested in founding the project, and all stakeholders are interested in satisfying their expectation, it is needed to propose an optimization approach for the MSWM that takes into account the multistakeholders involved. Furthermore, as the production and the composition of the municipal solid waste (MSW) depend on many factors including the population growth, consumption patterns, season and climatic conditions, the uncertainties associated to the MSWM must be considered. In this way, several contributions have been published, Habibi et al. (2017) developed a multi-objective optimization model for the supply chain of MSW in Tehran, Entezaminia et al. (2016) presented a model for the production planning in a green supply chain considering the traditional production system with recycling hubs. Other publications have focused on predicting the generation of the MSW through linear and nonlinear models, considering certain variables that affect the amount of MSW generation ( Sun and Chungpaibulpatana, 2017 ), or analysing the economic viability of a power generation project from MSW ( Pin et al., 2017 ). The dependence on time in the supply chain of MSW is an important issue, which has been recently considered ( Santibanez-Aguilar et al., 2017; Nguyen-Tron et al., 2017; Zhang and Huang, 2013; Dai et al., 2012 ). To determine the incentives for the government and recycling industries to invest in the MSWM, Zheng et al. (2014) analysed the application of the landfill gas-fired and MSW incineration to produce power, and presented a series of preferential policies and regulations to encourage the expansion of MSW to energy. Wang et al. (2018) introduced a multi-attribute decision analysis method for prioritizing the MSW treatment alternatives based on the interval-valued fuzzy set theory. Nevertheless, none of the papers mentioned above has taken into account the uncertainty in the availability of the MSW, the demand of the products obtained from them, or the multistakeholders involved at three different level of financial risk (optimistic, mean and pessimistic). Therefore, this paper proposes a model formulation to provide to the involved stakeholders a tool for decision making from a wider perspective.
What is municipal solid waste?
Municipal solid wastes (MSW), defined as trash, are highly nonhomogeneous mixture of residential, commercial, and industrial sectors. Typical residential and commercial MSW include clothing, disposable tableware, yard trimmings, cans, office disposable tables, paper, and boxes, whereas institutional and industrial MSW contain restaurant trash, paper, classroom wastes, wood pallets, plastics, corrugated box, and office papers. Although the composition of MSW could be highly variable, it is generally accepted that organic materials are the largest component of MSW. In the United States, the sum of the major organic components such as paper, yard trimming, food waste, rubber, wood, and plastics was over 83% in 2013, which was the largest component of MSW as shown in Table 8.3. In addition, MSW consist of some metals, and oftentimes, they need to be recovered prior to pyrolysis or subjecting to other conversion processes.
What is MSW in biogas?
However, a major challenge for biogas production from MSW is unawareness among people about the segregation of the organic and inorganic fractions of MSW. Second, composition variation is also an important factor that affects biogas production. This compositional variation may be attributed to seasons, changing lifestyles, and eating habits [19] ( Fig. 7.2 ).
What is MSW in the US?
MSW is commonly known as trash or garbage. In 2010, 250 million tons of MSW were generated in the United States. 5 MSW includes organic wastes such as paper, cardboard, food, yard trimmings, and plastics, and inorganic wastes such as metal and glass.
What is OFMSW in agriculture?
OFMSW is a mixture of food waste, paper and cardboard, yard trimmings, and other organic wastes main ly generated from residential, commercial, and institutional facilities. While it is one of the most commonly used feedstocks in solid-state AD, OFMSW is traditionally landfilled, with a small portion incinerated.
Does waste affect ground water?
If the waste has some biodegradable material, it must be proven through both laboratory studies on fresh waste and field studies (in old dumps) that the leachate from such waste will not impact the ground water in all the phase s of the landfill and has not impacted the ground water or the subsoil so far in old dumps.
What is waste minimization?
Waste minimization, the term employed in the RCRA statute, is defined to include both source reduction and certain types of environmentally sound recycling. EPA's highest priority is to achieve reductions through source reduction. However, if this is not achievable, then environmentally sound recycling is also an Agency priority.
How does combustion of municipal solid waste work?
Confined and controlled burning, known as combustion, can not only decrease the volume of solid waste destined for landfills, but can also recover energy from the waste burning process. This generates a renewable energy source and reduces carbon emissions by offsetting the need for energy from fossil sources and reduces methane generation from landfills.
Why is MSW combustion important?
Generally speaking, regions of the world where populations are dense and land is limited (e. g. many European countries, Japan), have greater adoption of combustion with energy recovery due to space constraints.
How does MSW work?
At an MSW combustion facility, MSW is unloaded from collection trucks and placed in a trash storage bunker . An overhead crane sorts the waste and then lifts it into a combustion chamber to be burned. The heat released from burning converts water to steam, which is then sent to a turbine generator to produce electricity.
When did MSW combust?
Combustion of MSW grew in the 1980s. By the early 1990s, the United States combusted more than 15 percent of all MSW. The majority of non-hazardous waste incinerators were recovering energy by this time and had installed pollution control equipment.
What is a reject derived fuel system?
Refuse derived fuel systems use mechanical methods to shred incoming MSW, separate out non-combustible materials , and produce a combustible mixture that is suitable as a fuel in a dedicated furnace or as a supplemental fuel in a conventional boiler system.
Can syngas be used to produce electricity?
The syngas can then be burned to produce electricity or further processed to produce vehicle fuel. As part of EPA’s effort to promote flexible, innovative ways to convert waste to energy, EPA finalized an exclusion to RCRA’s regulation for oil-bearing hazardous waste generated at a petroleum refinery in January 2008.
What is treated waste?
Treatment waste consists of sludge, byproducts, coproducts, or metal scraps resulting from a facility or plant. Sludge is any solid, semisolid, or liquid waste generated from a municipal, commercial, or industrial wastewater treatment plant, water supply treatment plant, or air pollution control facility exclusive of the treated effluent from a wastewater treatment plant. This includes electric arc furnace dust and baghouse dusts. A byproduct is a material that is not a primary product which is not solely or separately produced in a production process whereas coproducts are intentionally produced. Byproducts need further processing to be useful whereas coproducts are highly processed and can be sold as a commodity without further processing. Examples of byproducts include slag, fly ash, heavy ends, distillation column bottoms, etc. and coproducts include metals such as lead produced during the copper refining process. Scrap metal wastes include sheet metal, wire, metal tanks and containers, scrap automobiles, and machine shop turnings that are generally nonhazardous in nature.
Which federal agency handles medical waste?
Other federal agencies have issued safety regulations governing the handling of medical waste, including the Centers for Disease Control and Prevention, Occupational Safety and Health Administration, and the Food and Drug Administration.
What is solid waste policy?
Solid waste policy in the United States is aimed at developing and implementing proper mechanisms to effectively manage solid waste. For solid waste policy to be effective, inputs should come from stakeholders, including citizens, businesses, community based-organizations, non governmental organizations, government agencies, universities, and other research organizations. These inputs form the basis of policy frameworks that influence solid waste management decisions. In the United States, the Environmental Protection Agency (EPA) regulates household, industrial, manufacturing, and commercial solid and hazardous wastes under the 1976 Resource Conservation and Recovery Act (RCRA). Effective solid waste management is a cooperative effort involving federal, state, regional, and local entities. Thus, the RCRA's Solid Waste program section D encourages the environmental departments of each state to develop comprehensive plans to manage nonhazardous industrial and municipal solid waste.
What is hazardous waste?
The EPA, which regulates hazardous waste under Subtitle C of the Resource Conservation and Recovery Act (RCRA), considers a waste hazardous waste if it is dangerous or potentially harmful to human health or the environment. Hazardous waste can be liquids, solids, gases, or sludges and can be discarded household, industrial, or commercial products such as oil, paints, certain electronics waste, cleaning fluids or pesticides, or the by-products of manufacturing processes.
What is agricultural waste?
Agricultural wastes include primary crop residues that remain in fields after harvest and secondary processing residues generated from the harvested portions of crops during food, feed, and fiber production. This is generated during the production and distribution through decomposition of food, vegetables, or meat, removal of non-usable parts, removal of substandard products, and spoiling due to substandard packaging. Thus agricultural waste is generated at all stages of food system including farming, storage, processing, and wholesaling. The food scraps generated by retailers and consumers are not included in this category as these scraps enter the waste stream as municipal solid waste. Animal wastes are wastes generated from farms and feedlots, also known as Animal Feeding Operations (AFOs) or Concentrated Animal Feeding Operations (CAFOs), consisting of leftover feeds, manure and urine, wastewater, dead animals, and production operation wastes. They produce large amounts of waste in small areas. For example, EPA reports that a single dairy cow produces approximately 120 pounds of wet manure per day equaling to that of 20-40 people. The main problems of animal waste mismanagement are environmental, especially water pollution.
