Living review framework for better policy design and management of hazardous waste in Australia

The significant increase in hazardous waste generation in Australia has led to the discussion over the incorporation of artificial intelligence into the hazardous waste management system. Recent studies explored the potential applications of artificial intelligence in various processes of managing waste. However, no study has examined the use of text mining in the hazardous waste management sector for the purpose of informing policymakers. This study developed a living review framework which applied supervised text classification and text mining techniques to extract knowledge using the domain literature data between 2022 and 2023. The framework employed statistical classification models trained using iterative training and the best model XGBoost achieved an F1 score of 0.87. Using a small set of 126 manually labelled global articles, XGBoost automatically predicted the labels of 678 Australian articles with high confidence. Then, keyword extraction and unsupervised topic modelling with Latent Dirichlet Allocation (LDA) were performed. Results indicated that there were 2 main research themes in Australian literature: (1) the key waste streams and (2) the resource recovery and recycling of waste. The implication of this framework would benefit the policymakers, researchers, and hazardous waste management organisations by serving as a real time guideline of the current key waste streams and research themes in the literature which allow robust knowledge to be applied to waste management and highlight where the gap in research remains.

Construction of a spatial–temporal metabolic path for hazardous waste management based on the fusion of reported data and web text data

This study employs mining and fusion of the waste reported data and web text data to construct a spatial–temporal metabolic path for hazardous waste management. According to the reported data, the generation and inventory of organic solvent waste account for a large proportion of hazardous waste; thus, they were selected as the representative waste in the construction of metabolic paths from the generation to the final disposal during 2016 to 2019. Web text data were obtained by a web crawler to identify where waste was produced, stored, and disposed. Based on the matching logic, the reported data and web text data were fused to realize the spatio-temporal expression for the logical metabolic path. The results showed that the generation of organic solvent waste displayed rapid growth, increasing from 17,922 to 22,005 tons between 2016 and 2019. The number of waste production enterprises also showed growth, with most of them disconnected downstream, accounting for an average of 43.84% of the total metabolic paths. The number of metabolic paths representing the complete waste disposal decreased significantly by 23.02% during this period. Most of the waste was transferred outside the Chengdu metropolitan area for final disposal, accounting for an average of 14.90% of the total waste generation. In addition, the contributions to organic solvent waste were identified; the automobile and electronic device manufacturing industries were the major sources. These results provided insight into hazardous waste management, making a call for improvement in the existing management system. • A spatial–temporally metabolic path regarding hazardous waste is constructed. • The path is constructed through the fusion and mining of waste reported data and web text data. • The managerial issues related to the existing waste management system are identified. • Policy implications for hazardous waste management system optimization are proposed.

Hazardous waste management system for Thailand’s local administrative organization via route and location selection

ABSTRACT This study proposed a decision support system (DSS) for optimizing transportation routing and disposal hub location for Thailand’s local administrative organizations’ hazardous waste management. The first step is to choose the origin and destination, as well as to collect data for each route. Each route’s decision criteria were based on traffic quality and risk measures from the perspective of users. An analytic hierarchy process (AHP) was used to compute effective weights for decision criteria. To achieve optimal routing, AHP weights were combined with a zero-one goal programming technique. The DSS operates systematically and successfully, taking into account both transportation risk and socioeconomic factors, and provides appropriate routes. Overall, this waste management system may provide useful information to decision-makers for prioritizing disposal site alternatives and implementing feasible waste management actions. The zero-one location design was then used to determine the best hub location. Based on two scenarios of six and fifteen CoG hubs, the results revealed that the best model for managing a case company’s hazardous waste was to establish 15 hubs scattered throughout the country for collecting points and then transporting them to the waste disposal plant in Phitsanulok province. Locating the hub near sink points would reduce transportation costs and backhaul issues, reducing the environmental impact of GHG emissions and increasing system efficiency. Implications: The problem of waste pollution has become increasingly serious all over the world, particularly in developing countries that face significant pollution control challenges. End-of-life wastes cause economic, health, and environmental problems if they are not properly managed. As the world’s population and living standards rise, so does the amount of waste produced. The environmental impact is significant, with massive amounts of waste generated each year with only basic or minimal treatment to mitigate its impact. As a result, there is an urgent need for a method that can precisely optimize transportation routing and disposal hub location for Thailand’s local administrative organizations’ hazardous waste management (LAOs). The proposed decision support system (DSS) may provide useful information to decision-makers in prioritizing disposal site alternatives and implementing feasible waste management actions.

Locating a disinfection facility for hazardous healthcare waste in the COVID-19 era: a novel approach based on Fermatean fuzzy ITARA-MARCOS and random forest recursive feature elimination algorithm.

Hazardous healthcare waste (HCW) management system is one of the most critical urban systems affected by the COVID-19 pandemic due to the increase in waste generation rate in hospitals and medical centers dealing with infected patients as well as the degree of hazardousness of generated waste due to exposure to the virus. In this regard, waste network flow would face severe problems without taking care of hazardous waste through disinfection facilities. For this purpose, this study aims to develop an advanced decision support system based on a multi-stage model that was combined with the random forest recursive feature elimination (RF-RFE) algorithm, the indifference threshold-based attribute ratio analysis (ITARA), and measurement of alternatives and ranking according to compromise solution (MARCOS) methods into a unique framework under the Fermatean fuzzy environment. In the first stage, the innovative Fermatean fuzzy RF-RFE algorithm extracts core criteria from a finite set of initial criteria. In the second stage, the novel Fermatean fuzzy ITARA determines the semi-objective importance of the core criteria. In the third stage, the new Fermatean fuzzy MARCOS method ranks alternatives. A real-life case study in Istanbul, Turkey, illustrates the applicability of the introduced methodology. Our empirical findings indicate that “Pendik” is the best among five candidate locations for sitting a new disinfection facility for hazardous HCW in Istanbul. The sensitivity and comparative analyses confirmed that our approach is highly robust and reliable. This approach could be used to tackle other critical multi-dimensional problems related to COVID-19 and support sustainability and circular economy.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10479-022-04822-0.

Hazardous Solid Waste Management in Universitas Diponegoro: Planning Towards Environmental Sustainability

Universitas Diponegoro has a role in contributing to considerable numbers of hazardous solid waste from academic activities as it is the largest university in Central Java Province, Indonesia. Therefore, improper hazardous solid waste will cause potential disease for humans and pollute the environment. For this reason, proper hazardous solid waste management is urgently needed. This research aims to design hazardous solid waste management for Universitas Diponegoro as a pilot testing study. The research used questionnaires, surveys, in-depth interviews, and observations to construct an appropriate hazardous waste management system.

A WASTE MANAGEMENT IN THE SERVICE COMPANY FOR HAZARDOUS WASTE TREATMENT IN BALIKPAPAN

Because of the potential threats to the environment, hazardous waste management is critical. The design of a hazardous waste management system in Indonesia involves several regulations, including Government Regulation of the Republic of Indonesia or PP No. 22/2021 and the decree of The Head of Indonesian Environmental Impact Control Agency or BAPEDAL No. 01/1995. This study aims to assess the practice of these regulations by the service company for the hazardous waste treatment. The method is conducted with a descriptive idea and content analysis technique using a qualitative case study research approach to collect in-depth knowledge regarding waste management system. In this regard, the selected service company for hazardous waste treatment in Balikpapan could proof only six of the ten criteria of Indonesian legal standard examined so this study proposed a performance evaluation centered on hazardous waste management as sufficient for the implementation of hazardous waste management. To improve the waste management assessment, a series of alternatives based on the waste management hierarchy is suggested for further studies such as including reduction, storage, usage, processing, stockpiling, and dumping factors on their research.

An integrated model for management of hazardous waste in a smart city with a sustainable approach

Management of hazardous waste deals with the cost-effective, efficient, social, and environmental concern, and the concept of sustainability includes all of these issues. In this regard, new approaches are emerging to handle waste management according to the concept of smart city. In the current study, a mathematical model is developed for the hazardous waste location-routing problems to determine the best decisions in a hazardous waste Management (HWM) system. The proposed model aims to maximize the total profit of the HWM system and reduce the destructive effects of hazardous waste from the perspective of environmental and social impacts. In order to advance the efficiency and practicality of the proposed model, a solution method based on the non-dominated sorting genetic algorithm III, a recently presented metaheuristic procedure, is applied to efficiency solve the problem. The current study takes into account the concept of Information and Communications Technology ICT and Internet of Things technology in hazardous waste location-routing modeling. In addition, some sensitivity analyses are implemented to assess the behavior of the model and extract managerial insights.

Review: Medical Waste Management for Covid19

Introduction: Medical waste generation during the Covid19 pandemic increased by around 30%. Sources of medical waste generation are health care activities. If medical waste is not appropriately managed, it can pollute the environment and disturb health. The purpose of the review is to identify the potential of medical waste in health-care facilities in Indonesia when the Covid19 pandemic and to review medical waste management in Indonesia. The analysis uses a systematic literature review. Discussion: The potential of medical waste during the Covid19 epidemic is infectious waste (PPE wastes), sharps waste (syringes), chemical waste (expired medicines), and pharmaceutical waste (the used alcohol bottles when rapid tests). The hazardous waste management system refers to Government Regulation No. 101 year 2014 about Management of Hazardous and Toxic Waste and and Regulation of Minister of Environment and Forestry of Republic Indonesia No. P.56/MenlhkSetjen/2015 about Procedures and Technical Requirements for Waste Management Hazardous and Toxic From the Health Service Facilities. Infectious waste, sharps waste, chemical waste, and pharmaceutical waste are destroyed with incinerators. Syringe residues were damaged with a needle shredder. Residue and incineration ashes are processed using solidification. If the heavy metal content under the quality standards, then the waste can be landfill. Conclusion: The potential of medical waste during the Covid19 pandemic is infectious waste, sharps waste, chemical waste, and pharmaceutical waste. Medical waste generated must be appropriately managed. Proper medical waste management can prevent environmental pollution and the spread of disease. One of the processing of potential medical waste is incineration. The incineration system produces residue and ash waste that must further be handled so that it does not pollute the environment and disturb health.

A stochastic network design problem for hazardous waste management

Hazardous waste management is of paramount importance due to the potential threats posed to the environment and local residents. The design of a hazardous waste management system involves several important decisions, i.e., the determination of the locations and sizes of treatment, recycling and disposal facilities, and organizing the transportation of hazardous waste among different facilities. In this paper, we proposed a novel stochastic bi-objective mixed integer linear program (MILP) to support these decisions in order to reduce the population exposure to risk while simultaneously maintaining a high cost efficiency of the transportation and treatment of hazardous waste. Moreover, considering the inherent uncertainty within the planning horizon, the cost, demand and affected population are defined as stochastic parameters. A sample average approximation based goal programming (SAA-GP) approach is used to solve the mathematical model. The proposed model and solution method are validated through numerical experiments whose results show that uncertainty may not only affect the objective value but also lead to different strategic decisions in the network design of a hazardous waste management system. In this regard, the strategic decisions obtained by the stochastic model is more robust to the change of external environment. Finally, the model is applied in a real-world case study of healthcare waste management in Wuhan, China, in order to show its applicability.

Present situation of hazardous waste generation in China and grey model prediction

According to the 2008-2017 China Environmental Statistics Yearbook data, combined with GIS heat map, the current situation and regional distribution characteristics of hazardous waste generation and disposal in China were analyzed, and the GM gray model was constructed to predict its output in the next five years. The results show that it is predicted that by the end of 2023, hazardous waste production of China will reach 157,889,300 tons. It is suggested that take the government as the guidance, the production and disposal enterprises will jointly promote the development of hazardous waste resources, improve the existing treatment methods and strengthen the hazardous waste management system, thus breaking the deadlock of geographical mismatch.

Developing a hazardous waste management system with consideration of health, safety, and environment

This paper presents a novel mathematical model for hazardous waste collection problem. The study aims to introduce a model in order to improve health, safety, environment (HSE) issues for hazardous waste collection problem in addition to considering operational cost. In addition, technologies which will be applied at each facility are investigated. To extend previous networks in this field of study, the vehicles’ depot are considered,. In order to tackle the problem, ɛ-constraint and non-dominated sorting genetic algorithm II (NSGA-II) methods are applied. According to the results, we can state that NSGA-II mean value of comparison metrics are equivalent to the results of ɛ-constraint with confidence level of 95%. Moreover, the sum of the distance's mean from the ideal point for ɛ-constraint method is 4% less than NSGA-II which can be concluded as an acceptable result for NSGA-II algorithm. All in all, The presented model can help managers and decision makers to have a more comprehensive and thorough understanding the HSE issues with respect to the operational cost in the field of waste collection network design.

Optimal pricing and environmental improvement for a hazardous waste disposal supply chain with emission penalties

Hazardous waste management has become a municipal problem, associated with industrial development and changing consumption patterns. We study the hazardous waste management system as a supply chain with a disposal facility and a contractor, which serves customers with demand sensitive to price and environment impact. The government intervenes with this supply chain by imposing emission penalties that make the waste disposal facility responsible for reducing disposal process emissions. The Stackelberg game and Nash equilibrium are used to model the decision-making sequence between the disposal facility and the contractor. We specify different scenarios to model the hazardous waste management supply chain. The goal of this research is to find the optimal disposal service price and level of environmental improvement to mitigate adverse impacts and maximize profits. The applicability of dual-channel service in the hazardous waste supply chain is also investigated. Our study shows that the supply chain obtains the highest profit if both the disposal facility and the contractor operate in a centralized model. Under some scenarios, profitability improves if the disposal facility becomes active in waste collection and transportation under a dual-channel supply-chain model. Demand sensitivity to price and environmental impacts can affect the adopted level of improvement by disposal facilities.

A new multi-objective mathematical model for hazardous waste management considering social and environmental issues

Hazardous waste management incorporates collection, separation, treatment, recycling and disposal of hazardous wastes. In this paper, a new multi-objective mixed integer model is presented for hazardous waste collection problem. The model aims to minimize transportation and construction costs, and environmental and population risks in hazardous waste management systems. This model is applied in a case study of Iran in order to help decision makers to decide on the location of separation, treatment, recycle, disposal centers, and established technology in treatment center. Moreover, this paper specifies routes between different facilities in collection network. For addressing population and environmental impacts and economical costs, three objective functions including total costs, total population exposure risk, and environmental risks are considered. An augmented e-constraint method is used to generate Pareto optimal solution for these conflicting objectives. Finally, proposed model is utilized in our case study and numerical results and some managerial insights are provided.

Hazardous waste management system design under population and environmental impact considerations

This paper presents a multi objective mixed integer location/routing model that aims to minimize transportation cost and risks for large-scale hazardous waste management systems (HWMSs). Risks induced by hazardous wastes (HWs) on both public and the environment are addressed. For this purpose, a new environmental impact definition is proposed that considers the environmentally vulnerable elements including water bodies, agricultural areas, coastal regions and forestlands located within a certain bandwidth around transportation routes. The solution procedure yields to Pareto optimal curve for two conflicting objectives. The conceptual model developed prior to mathematical formulation addresses waste-to-technology compatibility and HW processing residues to assure applicability of the model to real-life HWMSs. The suggested model was used in a case study targeting HWMS in Turkey. Based on the proposed solution, it was possible to identify not only the transportation routes but also a set of information on HW handling facilities including the types, locations, capacities, and investment/operational cost. The HWMS of this study can be utilized both by public authorities and private sector investors for planning purposes.

Improved approaches to the network design problem in regional hazardous waste management systems

This paper investigates the network design problem arising from the regional hazardous waste management system. The problem is to identify the locations of various waste facilities, and determine the transportation routes of hazardous wastes and waste residues between those waste facilities. Aiming at minimizing jointly the total cost and total risk, the problem is formulated as a multi-objective mixed integer linear programming model. By exploiting the advantages of the model, three multi-objective optimization approaches are customized to find highly qualified non-dominated solutions. The effectiveness and efficiency of the approaches are examined both on a hypothetical case and a realistic case.

Use of theoretical waste inventories in planning and monitoring of hazardous waste management systems.

Hazardous waste (HW) generation information is an absolute necessity for ensuring the proper planning, implementation, and monitoring of any waste management system. Unfortunately, environmental agencies in developing countries face difficulties in gathering data directly from the creators of such wastes. It is possible, however, to construct theoretical HW inventories using the waste generation factors (WGFs). The objective of this study was to develop a complete nationwide HW inventory of Turkey that relies on nation-specific WGFs to support management activities of the Turkish Ministry of Environment and Urbanization (MoEU). Inventory studies relied on WGFs from: (a) the literature and (b) field studies and analysis of waste declarations reflecting country-specific industrial practices. Moreover, new tools were introduced to the monitoring infrastructure of MoEU to obtain a comprehensive waste generation data set. Through field studies and a consideration of country specific conditions, it was possible to more thoroughly elucidate HW generation trends in Turkey, a method that was deemed superior to other alternatives. Declaration and literature based WGFs also proved most helpful in supplementing field observations that could not always be conducted. It was determined that these theoretical inventories could become valuable assets in supporting regulating agencies in developing countries for a more thorough implementation of HW management systems.
