One of the most urgent environmental problems today is the pollution of the environment by emissions of harmful substances and industrial waste. The negative impact on the environment and people is becoming more widespread, and its disposal methods inhibit the development of the economic system. In a market economy, entrepreneurs are not interested in increasing environmental costs, which naturally lead to higher production costs and reduce profits. The impact on the environment is becoming more widespread every year and has led to an ecological crisis in some parts of the world. Waste recycling has been constantly discussed since a person “produces” more than 250 kg of household waste per year. At the enterprise, these figures reach 10 000 kg. In recent years, Ukraine has imported about 30-50 thousand tons of PET granulate, which is gradually accumulating in landfills in the form of packaging, bottles, films. Such hazardous pollutants affect the environment through soil and water. In contrast, Ukraine does not yet have successful experience in waste management. In our opinion, such behavior is the ignorance of the population about waste disposal and replacement of a particular product with a more environmentally friendly one. The functioning of enterprises and farms does not always have the equipment to dispose of waste, and there is no room for the disposal of unnecessary products and raw materials. However, the problem of lack of innovative equipment arises due to a lack of adequate funding. Therefore, the lack of possibilities for a comprehensive solution to the situation creates a barrier, which does not allow to take proper measures to eliminate and reduce the amount of garbage. Despite many regulations and legal frameworks for regulating waste management, there is no cost-effective policy, and there is no regional waste management program and plan for their proper disposal. It can be concluded that the recycling and disposal of waste will reduce the need for waste incineration, create conditions for improving the economic component of the region and the country as a whole with an account of environmental quality standards. The paper pays attention to the essence of waste disposal; identified ways to recycle garbage.

From a circular economy perspective, the recovery and reuse of waste plays a fundamental role. Foundries purchase hundreds of millions of siliceous sands every year to create molds and cores that give shape to the casting. These sands, after several uses, become waste that must be properly recovered or disposed of; they are called waste foundry sands (WFS). The reuse of WFS leads to a reduction in: (i) the consumption of raw materials; (ii) the emissions into the atmosphere; and (iii) the amount of waste sent to landfill—on the other hand, the impact that their use generates on the environment and human health must be carefully assessed. Leaching tests are a fundamental tool for establishing the hazardousness of a waste and its release of contaminants into the environment. This paper presents an analysis of the scientific literature regarding the chemical characteristics of WFS and their release following leaching tests carried out in the laboratory; the environmental standards adopted by the countries that have issued guidelines regarding the reuse of WFS will also be presented.

Studies on comparison of principal factors between CAER (China Actual Environmental Risk) and CZER (China Zero Environmental Risk) from Behavior Angle are seldom found, so we studied the theme above in this thesis. By analysis, we have known that on one hand, there are such aspects in common as natural cause, production action, living action, production waste disposal, and living waste disposal between CAER and CZER. On the other hand, they are different in such aspects as Government surveillance only for CAER, and public management and market management only for CZER. And our related advice is as follows: first, careful protection of natural environment. Secondly strict surveillance on production of waste from such behaviors as enterprise production and human living action by market management, public management, and Government surveillance, etc.. And thirdly great encouragement to arouse interest in technological innovations friendly with the environment in waste disposal, etc..

It is, clearly, a Government responsibility to enact laws and promulgate regulations for control of industrial pollution. The main techniques for soil industrial wastes disposal, namely, landfarming and landfilling, profit from the extensive knowledge acquired, in past decades, in the field of water and air pollution control and must be analysed within a comprehensive system for hazardous waste management, with its legal and administrative aspects. This paper presents some general principles of a Hazardous Waste Management System, which are broadly applicable, regardless differences between States or Countries. Finally, it discusses the specific case of Hazardous Wastes Management in the State of Bahia, Brazil and makes some suggestions for its improvement.

Intensification of dairying on irrigated pastures has led to concern over the microbial quality of shallow groundwater used for drinking purposes. The effects of intensive dairying and border-strip irrigation on the leaching of E. coli and Campylobacter to shallow groundwater were assessed over a three-year period in the Waikakahi catchment, Canterbury, New Zealand. Well selection excluded other sources of contamination so that the effect of dairying with border-strip irrigation could be assessed. Groundwater samples (135) were collected, mostly during the irrigation season, with E. coli being detected in 75% of samples. Campylobacter was identified in 16 samples (12%). A risk assessment of drinking water with these levels of Campylobacter was undertaken. A probability distribution was fitted to the observed Campylobacter data and the @RISK modeling software was used, assuming a dose response relationship for Campylobacter and consumption of 1 L/day of water. The probability of infection on any given day in the study area was estimated at 0.50% to 0.76%, giving an estimated probability of infection during the irrigation season of 60% to 75%. An epidemiological assessment of the Canterbury region comparing areas encompassing dairy within major irrigation schemes (∼55% border-strip irrigation) to two control groups was undertaken. Control group 1 (CG1) encompasses areas of dairying without major irrigation schemes, and a second larger control group (CG2) comprises the rest of the Canterbury region. Comparisons of the subject group to control groups indicated that there was a statistically significant increase in age-standardised rates of campylobacteriosis (CG1 Relative Risk (RR)=1.51 (95% CI = 1.31-1.75); CG2 RR = 1.51 (1.33–1.72)); cryptosporidiosis (CG1 RR = 2.08 (1.55–2.79); CG2 RR = 5.33 (4.12–6.90)); and salmonellosis (CG2 RR = 2.05 (1.55–2.71)).

Annually, increasing volumes of industrial and municipal waste generation and disposal, leading to increasing anthropogenic environmental and sanitary-epidemiological pressure on the environment and, as a consequence, significant environmental damage and associated economic damage to natural ecosystems, represent one of the main threats to environmental safety territories, life and health of the population. At the same time, numerous valuable components extracted from processed production and consumption wastes can be an important source of reserve for the development of industries and sectors of the economy, entrepreneurial activities in the use of secondary resources for production, services, works and energy. This factor dictates the need to search for new sound management, economic, organizational and technical approaches and solutions to lawmaking, planning and forecasting the cost-effective organization of the system of separate collection, processing, disposal, disposal of production and consumption waste, the development of an appropriate industrial, scientific and technological infrastructure, increasing the share of secondary material and energy resources extracted from waste, the development of instruments of state oh support and economic incentives for this activity.

Landfills have become the main environmentally sound form of final disposal of urban solid waste and when properly managed, do not cause harm or risks to public health. The objective of this work was to perform an analysis of the environmental quality of the Landfill in Campina Grande / PB, in order to verify if the landfill meets the technical standards and environmental requirements. In the analysis of the data collected were used, as reference, the standards NBR 8,419 (ABNT, 1992) and NBR 13,896 (ABNT, 1997). From the analyzed data, it was verified, that the landfill presents technical and operational conditions for the employees to work and an operability that makes possible the accomplishment of the activities in a satisfactory and environmentally safe way. Thus, the studied area is appropriate for the waste disposal activity according to NBR 8,419 (ABNT, 1992) and NBR 13,896 (ABNT, 1997). However, improvements are suggested for the internal access routes, since, because they are not paved, it may hinder the passage of trucks that discharge the waste on days of intense rain.

Information systems MRP, ERP or ERP II and is now the standard used in many enterprises. Many of these companies also has a statutory obligation to monitor and report information about the waste. For this purpose, they become extremely useful environmental information systems in the enterprise. These systems can lead to a measurable positive economic impact in the enterprise. In addition, legislation in Poland forced by the municipalities need to organize collection system and waste disposal. The introduction of the so-called junk reform enabled municipalities to enable the use of information systems to inform about the dates of the waste collection, including mobile technologies. The article presents the use of IT systems in managing the economy of municipal waste.

The snow and glacial ice on permanent snowfields must serve as both the water source and the receptacle for wastes for any human habitation. In addition, the snow also serves as the support media for any structural foundations and hence the thermal aspects of water supply and waste disposal can be critical. Most activity has occurred on the ice caps of Greenland and Antarctica and has ranged from small transient field parties to large permanent facilities in continuous use for over 25 years. Novel procedures to insure the reliable production of good quality water are described as well as the recommended criteria for water quantity depending on the size and duration of the activity. The various methods of wastewater disposal that have been used at temporary camps and permanent stations are described along with the results from studies that defined the fate of the wastewater following its discharge to the snow. Such definition is important to insure protection of the water supply as well as the thermal integrity of any structural foundation. Key words: water supply, water quality, sewage waste disposal, ice cap, glaciers, snowfields.

Since 2017, a housing renovation program has been implemented in Moscow, which is a unique program aimed at settling and demolishing shabby low-rise housing stock and new construction on the vacated territory. The renovation program raises a fundamental issue of construction waste disposal. Many current technologies of building mass demolition imply dusting of adjacent territories, have low efficiency in transporting construction waste generated in this process and lead to environmental problems resulting from its disposal, so the rational use of construction waste becomes one of the environmental protection's main points. In this research, we address the question: how the principle "Green Digital Technologies," reflected in the Moscow development concept "Smart City," which is a part of the housing renovation program in Moscow, is currently implemented. Three implementation ways of this principle have been revealed: contraction of "smart houses" under the renovation program according to smart 1.0 standard; use of BIM-technologies in the program; use of "smart demolition" technology. It is proposed to consider the process of recycling construction waste after demolishing old houses under the renovation program according to the principles of sharing and circular economy to increase the program's environmental friendliness and reduce environmental risks for the Moscow population.

Recycling building demolition waste in addition to environmental benefits is also economically interesting. In addressing the environmental issues it is recommended to give priority to recovery and rational utilization of waste with regard to their basic characteristics before disposal respectively storage. Issue of the use of recycled materials in concrete structures and their disposal in the world and in our longer pays much attention. Use and recycling of construction materials is a great asset for more prospective and progressive methods of construction waste utilizations. The program focused on waste management is therefore necessary to reconcile economic and environmental aspects in order to come to an optimal solution of the issue of waste and environmental protection.

After decades of turmoil and international sanctions much of the key civil infrastructure within Iraq has fallen into disrepair, leading to a considerable decline in the provision of basic and essential municipal services. This is particularly true of waste and resource management services that have seen years of underdevelopment and deterioration. This has resulted in a lack of provision of basic public services in the waste sector which have been replaced by a burgeoning unregulated informal market in waste collection, disposal and recycling. In response, a National Solid Waste Management Plan (NSWMP) for Iraq was developed in 2007, to plan for the strategic development of all aspects of waste management in the country over the coming 20 years. In particular, the NSWMP focuses on policy development and integrated planning regarding regulatory framework, economic aspects, institutional capacity, citizen and technical education, and technical and operational development. This paper summarizes the key objectives, challenges and subsequent recommendations contained in the NSWMP for Iraq.

To preserve the ecological balance and health of the population of the African continent, it is necessary to maintain the cleanliness of the surrounding rivers, lakes and ocean coasts. Oil production, transportation of oil and petroleum products inevitably lead to pollution of sea waters due to accidents on tankers, equipment breakdowns, and fires. Oceanic coasts are of great importance for the development of the tourism industry, which plays a significant role in the national economies of African countries. However, many coastal areas are contaminated with industrial and household waste, oil refining waste and sewage. As a result of the growth of cities, the increase in the number of urban residents and the development of industry, a huge number of substances that do not decompose naturally is discharged into water sources. Currently, domestic sewage in most coastal cities does not meet modern sanitary requirements, since the repair of old and the laying of new sewage treatment plants require large financial investments. In the interests of nature and human health, a number of international instruments has been adopted prohibiting the import of hazardous and radioactive waste, as well as the dumping or incineration of hazardous waste in the oceans and inland waters on the African continent. In some African countries, periodic clean-up activities are carried out on ocean and river coasts, but they are ad hoc and do not have a decisive impact on the state of contaminated areas. Experts of international environmental organizations have proposed a set of measures for the conservation and rational use of water resources: construction of wastewater treatment plants; mandatory environmental assessment of all major water management projects; development of measures to eliminate possible damage; control of new industrial installations and industrial waste disposal; design and operation of landfills based on reliable hydrogeological information and environmental expertise. However, these regulations are often violated, and solving the problem of coastal water pollution remains a distant prospect.

The production of municipal solid waste (MSW) represents one of the greatest challenges currently faced by waste managers all around the world. In Brazil, the situation with regard to solid waste management is still deficient in many aspects. In 2015, only 58.7% of the MSW collected in Brazilian cities received appropriate final disposal. It was only as late as 2010 that Brazil established the National Policy on Solid Waste (NPSW) based on the legislation and programmes established in the 1970s in more developed countries. However, the situation with regard to MSW management has changed little since the implementation of the NPSW. Recent data show that, in Brazil, disposal in sanitary landfills is practically the only management approach to MSW. Contrary to expectations, despite the economic recession in 2015 the total annual amount of MSW generated nationwide increased by 1.7%, while in the same period the Brazilian population grew by 0.8% and economic activity decreased by 3.8%. The article describes the panorama with regard to MSW in Brazil from generation to final disposal and discusses the issues related to the delay in implementing the NPSW. The collection of recyclable material, the recycling process, the application of reverse logistics and the determination of the gravimetric composition of MSW in Brazil are also addressed in this article. Finally, a brief comparison is made between MSW management in Brazil and in other countries, the barriers to developing effective waste disposal systems are discussed and some recommendations for future MSW management development in Brazil are given.

In order to justify the effectiveness of the preparation and the feasibility of using secondary wood fiber semi-finished products by a dry grinding method, the physical phenomena and regularities of the mechanism for the preparation of secondary wood fiber semi-finished products by the proposed method are determined and investigated, which characterize the technological process of preparation in air and their possible future use as semi-finished products or in the manufacture of finished products products. The process of dissolution of wood fiber waste was studied, the mechanical effect on wood fiber waste due to face-cross cutting (cutting, crushing, flattening, breaking) and aerodynamic phenomena (breaking, collision, dissolution, fibrillation), contributing to the formation of external and internal fibrillation of the secondary wood fiber, is described. increase in specific surface in the absence of high temperatures and pressure, without the addition of chemical additives, without the use of water and steam. The performed studies allow us to propose a new method and system for the preparation of wood fiber waste by dry grinding, justifying their economic and environmental feasibility.

Purpose – This paper examined the current status of municipal solid waste management across Nigeria. The core aspects covered are generation, characterization, collection, scavenging, open dumping, disposal and environmental implications of poor solid waste management. The purpose of this paper is to present a comprehensive overview of the current state of municipal solid waste management in Nigeria. Design/methodology/approach – This study was executed by a combination of an extensive literature search and field study. Solid waste generation rates for 31 Nigerian cities were obtained from literature. In addition, characteristics of municipal solid waste from 26 Nigerian cities were also obtained from literature. Other aspects such as characterization of solid waste obtained from final dumpsite and heavy metals accumulation in solid waste dumpsites were undertaken first hand. Findings – Solid waste generation rate was found to vary from 0.13 kg/capita/day in Ogbomosho to 0.71 kg/capita/day in Ado-Ekiti. Factors affecting solid waste generation rates were identified. Typically, food waste was found to constitute close to 50 percent of overall municipal solid waste in Nigerian cities. This study shows that the rate of generation of plastics, water proof materials and diapers has assumed an upward trend. Due to the dysfunctional state of many municipal waste management authorities, many cities have been overrun by open dumps. For instance, more than 50 percent of residents of Maiduguri in northern Nigeria and Ughelli in southern Nigeria dispose of their waste in open dumps. Indiscriminate disposal of waste has also resulted in the preponderance of toxic heavy metals in agricultural soils and consequent bioaccumulation in plants as well as groundwater contamination. Research limitations/implications – The main limitation of this research is municipal waste management authorities do not have relevant data. Hence, there was heavy reliance on published materials. The status of waste management in Nigeria is very deplorable and therefore poses serious threats to public and environmental health. There is urgent need for both government and individuals to adopt holistic and sustainable waste management strategies in order to safeguard public/environmental health. Practical implications – Findings from this paper can form a veritable resource for the formulation and implementation of sustainable municipal solid waste management framework and strategies in Nigeria. Originality/value – While most studies on municipal solid waste management in Nigeria are focussed on selected cities of interest, this particular study cuts across most cities of Nigeria in order to present a broader and holistic view of municipal solid waste management in Nigeria. The paper has also unraveled core municipal solid waste management challenges facing Nigerian cities.

Improper management of municipal waste has become a growing concern globally due to its impact on the environment, health, and overall living conditions of households in cities. Waste production has increased because households do not adopt waste management practices that ensure sustainability. Previous studies on household waste management often considered socio-economic aspects and overlooked the environmental and behavioral factors influencing the disposal practices and health status. This study adopted four constructs, defensive attitude, environmental knowledge, environmental quality, and waste disposal, by employing a structural equation modeling approach to explore research objectives. Data from 849 households of the Islamabad-Rawalpindi metropolitan was collected by using a multi-stage sampling technique. The structural model results showed that the two constructs, environmental knowledge and defensive behavior, positively affect household health status. The most significant health-related considerations are waste disposal and environmental quality, both of which negatively impact health status and do not support our hypothesis. The results provide valuable perspectives to enable households to engage actively in waste management activities. The findings indicate that understanding the intentions of household health status drivers can assist policymakers and agencies in promoting an efficient and successful community programmes related to sustainable solid waste management by allowing them to foster how the desired behavior can be achieved.

The principles of selection and creation of rational methods of disposal and recycling of wastes are based on the fact that the problem of waste is an interconnected environmental-economic and technological problem, and the waste itself should be considered as technogenic raw materials of complex organo-mineral composition. Therefore, the main purpose of the work is to define methods for recycling waste and their environmental aspects. To achieve this goal, the methods of analysis, spectroscopy were used. It is determined that the final treatment of waste, to date, means either their disposal in a landfill or incineration, which adversely affects the environment. Methods for identifying the material of the object, as well as algorithms for the selection and recognition of objects by processing data from the computer vision system are considered. High accuracy is shown in 94.12% identification of plastic polymers.

Anthropogenic geoecology was developed at the end of the 20th century, but continues to face challenges in an integrated methodological approach to assessing the pollution of territories with long-term consequences of natural resource extraction. The consequences of extraction and primary processing of natural raw materials are the lack of effective control over the territories once the ore mining is completed. In order to develop effective methods to control the development of hazardous natural and man-made processes in the areas of inactive waste disposal facilities, it is necessary to analyze a sufficiently large set of data, including the condition of ground and surface waters, soils, flora, the efficiency of waste disposal facilities protection from direct or indirect impact on the natural environment. Research on modeling the processes of transfer and accumulation of pollutants includes a general assessment of the direction of man-made flows and selection of vegetation for phytoremediation of territories along the boundaries of the facilities as well as the direction of pollutant migration. The impact of mining facilities (dumps, tailings reservoirs) is directly correlated with the time of their existence, the toxicity and the rate of transformation of the components contained, the economic efficiency of their further utilization or conservation. Thus, the methodological approach to the rehabilitation of environmentally disadvantageous areas in places where mining and primary processing of resources is completed requires integration of several techniques and methods to assess the existing environmental situation. It also includes the speed and direction of its evolvement, and the economic assessment of damage to the natural environment. The introduction of tested recovery techniques will prevent the expansion of territories with irreversible destruction of geosystems, which led to a complete loss of productivity of the reproducing resources.

This paper firstly reviews the microbiological aspects of the accumulation of xenobiotic and non-xenobiotic substances from industrial and domestic waste water treatments, with particular reference to hydrocarbons, pesticides and inorganic plant nutrients. The paper goes on to argue that if water bodies are to be used to establish recreational fisheries as well as for water supply and effluent disposal, then the management aim may need to be one of controlled eutrophy. Ramifications of this proposal are considered. The biological aspects of the impact of other recreational and amenity uses of water bodies on water and environmental quality is briefly described. The paper concludes by discussing the training required by potential water managers.

Introduction: Waste processing in Final Disposal Sites (FDS) in Indonesia is still dominated by open dumping. This condition causes health and environmental problems and inhibits the achievement of Sustainable Development Goals (SDGs) 2030. Waste is biomass that can be converted into electrical energy through the Waste-to-Energy Plant (WtE Plant) installation. This article aimed to illustrate the potential of WtE Plant in the FDS in Indonesia in supporting the achievement of SDGs 2030. Discussion: Most waste in the FDS are dominated by organic waste with the highwater content of 60-70% but have a calorific value almost equivalent to sub-bituminous coal. Most studies show the WtE Plant uses a thermal method (incinerator) than other technologies because it has a superior value in the technical aspects (easy operation and high generated energy around 9.86%), economy aspects (medium investment value, but high profit with moderate payback period around 6.5 years) environmental aspects (reduction of waste up to 70-80% and emissions), and lower public health impacts than those produced by open dumping and coal systems. For environmentally safe optimal results, it is necessary to reduce wastewater content, increase pollution control units, and implement an integrated monitoring system. Conclusion: The implementation of WtE Plant can accelerate to achieve the SDGs 2030, especially the 7th, 8th, 12th, and 13th goals concerning clean and affordable energy, decent jobs and economic growth, responsible consumption and production, and addressing climate change, respectively.

In activities, the community produces waste so that the production of waste is increasing over time. For this reason, it is necessary to carry out effective and efficient waste management. This study aims to determine the strategy of waste management managed by the Environmental Agency at the Galuga Landfill, Galuga Village, Cibungbulang District, Bogor Regency, in this study used descriptive research methods using a qualitative approach. The informants in this study were the Waste Management Section, the Head of the Galuga Landfill, Garbage Transport Officers, Community Leaders, and local residents. The collection of data and information is done by means of interviews, and documentation. The data analysis technique used is SWOT analysis by taking into account all internal and external aspects of the organization, namely strengths, weaknesses, opportunities, and threats. Based on the results of the SWOT calculation, the Galuga solid waste subsector is in quadrant one, namely internal and external strong, with the result that the value of the difference between strengths and weaknesses on internal factors shows a positive value and the value of the difference between opportunities and threats on external factors also shows positive, so the strategy what will be developed to overcome strategic issues that arise is an aggressive strategy in implementing landfill management, such as establishing a waste zoning pattern, improving services and efforts to reduce waste through 3R.

Hazardous Waste Management is a special course offered to students whose major is Environmental Engineering. It is offered to let students know basic knowledge and technologies of hazardous waste (HW) processing and disposal, so that they can solve problems on HW processing and disposal. With increasing development of processing and synthesis of substances, lots of hazardous waste is generated as side-products. As more importance was attached on environment, requirement on hazardous waste management is more stringent than ever before. In order to enhance the competitiveness of undergraduates in using English, it is necessary to develop this course as a bilingual course. This paper first analyzes the basic conditions of this course. Then it proposes a developing plan for the course from the following aspects: adjustment of the course, reorganization of the textbook, teaching method, teaching mode, test database and exercise database and ways to increase teaching quality of this course.

To study the environmental impact of a project of 8 inches integrated circuit chip (8IICCP), investigation and analysis on engineering features, process flow, pollution and treatment of waste water, waste gases, and waste solids were done in this paper. The results showed that it would produce industrial 4110 m3/d of wastewater in the production in which 2920 m3/d of process waste water needed to be treated. After being treated, F-, NH3-N, Phosphate, COD(Chemical Oxygen Demand), TOC(Total Organic Carbon) and SS(Suspended Solid) concentrations in effluent of industrial wastewater would be 1.85 mg/L, 1.85 mg/L, 0.32 mg/L, 119.7 mg/L, 58.7 mg/L and 34.2 mg/L respectively. It also would produce many kinds of waste gases in which 4 kinds of them needed to be treated by local scrubber systems respectively. After being treated, the emissions can satisfy the demand. All predicted results can meet the requirements of relevant state standards. Moreover discharging volume of waste liquids and solids and their treating plan had been presented. This project is feasible on aspects of water, air and waste solid environmental influence.

As the current global trend towards more stringent environmental standards, technical applicability and cost-effectiveness became key factors in the selection of adsorbents for water and wastewater treatment. Recently, various low-cost adsorbents derived from agricultural waste, industrial by-products or natural materials, have been intensively investigated. In this respect, the eggshells from egg-breaking operations constitute significant waste disposal problems for the food industry, so the development of value-added by-products from this waste is to be welcomed. The egg processing industry is very competitive, with low profit margins due to global competition and cheap imports. Additionally, the costs associated with the egg shell disposal (mainly on landfill sites) are significant, and expected to continue increasing as landfill taxes increase. The aim of the present review is to provide an overview on the development of low-cost adsorbents derived from eggshell by-products.

We are currently experiencing a critical period for the prevention and control of the COVID-19 pandemic. COVID-19 related waste is a threat to global public environmental health. Medical waste management during this pandemic is one of the major issues facing public service organizations such as municipalities, which is of great importance in terms of logistics, environment and social aspects. The discussion of logistics operations is related to the collection, transportation and disposal of waste, which imposes high expenses. Many methods have been applied to develop and improve waste management policies in the literature. Apart from these studies, very few researchers have improved vehicle operations in waste management considering environmental aspects and the possibility of outsourcing. In this paper, by examining the gaps in the field, we try to explain and formulate the sustainable medical waste management problem for pandemics. Finally, by designing several practical examples with different scales, we solve the problem using CPLEX solver, compare different conditions and discuss the practical implications using the sensitivity analysis of demand parameter.
