Characteristics and management of municipal solid waste in Uyo, Akwa Ibom state, Nigeria

Increased urbanization and population lead to increased consumption of manufactured goods. This ultimately results in increased production of waste. Identifying its composition is crucial for planning an effective solid waste management strategy. This study assesses the characteristics and composition of the waste generated within the Uyo Capital City Development Area of Akwa Ibom State, Nigeria. This is to aid in developing a scientifically supported waste management pilot system for the state. Direct waste sorting and characterization were conducted on the municipal solid waste arriving at the landfill during the study period. Over 50% of the generated wastes are recyclables and composed of plastics, metals, and paper, while the fraction of organic waste is over 30%. Similarly, the waste generation per capita is 1.34 kg/person/day, while the generation forecast over the next ten years is estimated to increase by approximately 40%. Furthermore, over 9,000 surveys were completed by residents to establish a problem statement about the existing waste collection and disposal system, and possible solutions. Importantly, a majority of survey respondents were willing to source-separate their wastes and supported paying a fee for adequate waste collection. This strongly indicates that an integrated waste management system could be established to generate value from the collected waste. Supplementary revenue can be generated through composting, recycling, and land reclamation.

Evaluating Drivers and Barriers of Integrated Waste Management System Implementation in Indonesian Construction Industry: A DEMATEL-Based Analytical Network Process

The growth of construction industries in Indonesia creates an increasing level of generated construction waste. The limited implementation of ISO 14001 in the Indonesian construction industry might indicate the limited implementation of waste management based on sustainability principles. Therefore, this study aims to explore the drivers and barriers to implementing integrated waste management in construction industries. The Content Validity Index (CVI) and Modified Kappa methods were utilized to validate the indicators from the literature review. A total of 18 driver factors and 21 barrier factors in six dimensions were assessed by seven experts. This study then employs the decision-making evaluation and laboratory-based analytical network process (DEMATEL-based ANP) to find the weight and relation between each indicator and dimension. The results show that environmental awareness is the most important factor that drives construction industries to implement waste management in their company. In contrast, a lack of education about waste management is the most significant factor that inhibits construction industries from implementing sound waste management systems.

Sustainable urban development: Evaluating the potential of mineral-based construction and demolition waste recycling in emerging economies

Widespread illegal disposal of surging construction and demolition waste (CDW) is a prominent threat to recycling, leading to resource wastage and environmental issues. The lack of data is a major barrier to designing an effective waste management system in emerging economies. Employing a mixed-method approach, a cross-sectional case study was conducted on an Indian city to assess the existing system and investigate the root causes of low recycling rates and limited demand for recycled materials. The study finds that (a) illegal disposal is prevalent due to the "end-of-pipe" approach of the waste management system, (b) policy enforcement on waste generators is weak, (c) low-rise residential buildings are the major contributor of waste, (d) low demand for recycled material is due to lack of awareness, marketing, incentives, and high costs, (e) transportation costs are 50 % higher than the recycled material cost, and (f) lack of segregation leading to the production of low-value materials. All these factors make recycling unattractive and the circular economy (CE) unfeasible. Stakeholder awareness, a centralized trading platform, and integrated waste management systems are essential to promote recycling and advance SDGs 9, 11, and 12, focusing on industry, sustainable cities, and responsible consumption and production.

A Framework to Assess Advanced Reactor Spent Fuel Management Facility Deployment

Advanced nuclear reactors offer various operational advantages over existing light water reactors but could produce types of spent nuclear fuel (SNF) with a wide variety of forms and characteristics depending on how many different concepts are deployed. Each advanced reactor SNF type potentially poses unique management challenges. New planning efforts will be necessary to anticipate how the management requirements of advanced reactor SNF will affect the deployment of an integrated waste management system. This paper applies a framework of high-level facility deployment milestones to a generic SNF management system, reviewing them together with the advanced reactor SNF characteristics and management requirements. This allows for the investigation of factors that influence facility and system deployment, and ultimately, the identification of challenges facing the deployment of different kinds of SNF management facilities. The back end of the once-through fuel cycle is examined for four advanced reactor system technology types: sodium-cooled fast reactors, high-temperature gas-cooled reactors, liquid-fuel molten salt reactors, and lead-cooled fast reactors. It is observed that milestones earlier in the facility deployment process (e.g., siting and facility design) are more impacted by the uniqueness of advanced reactor SNF characteristics than others (e.g., construction and testing). Ultimately, none of the differences are seen as fundamentally disqualifying in a technical sense; however, they should be considered early, potentially as part of reactor design, to avoid issues in the future.

Integrated MSW management system in the Russian Federation: problems of interpretation and formation

The object of the study is the formation of an integrated MSW management system within the framework of the national project "Ecology" and the federal project "Integrated Solid Municipal Waste management System". The subject of the study is organizational, methodological, legal, financial, economic, industrial and technological problems that make it difficult at the federal and regional levels to achieve the annual and final planned indicators of these projects in 2024. The purpose of the work is a general description of the integrated MSW management system being created, as well as to identify the main problems of its formation in the new financial and economic environment reality. The author considers the planned target indicators of the federal project and their correlation with the indicators achieved in 2019-2022. Special attention is paid to the three-fold decrease in the initial planned indicator for recycling, which occurred due to insufficient development of the MSW recycling infrastructure, and the threat of non-fulfillment of the utilization indicator in 2024, which persists even after that. The methodological basis of research is an integrated approach that allowed the use of methods of systematic, comparative, factorial and economic-statistical analysis, content analysis, and also synthesis. The scientific novelty of the work lies in the disclosure of an integrated system as a set of methods for handling MSW, located among themselves in a certain hierarchy of applications, the last of which is waste disposal, and the smaller its scale and the damage caused to the environment, the greater the level of consistency the system demonstrates. Neutralization and energy utilization do not fully solve the problem, since they leave a lot of harmful combustion products. Recycling is much more environmentally friendly, the degree of development of which should be considered as the second important criterion for the development of an integrated waste management system. The reduction by the curators of the MSW management reform of the initially stated recycling targets for 2024 by three times is actually an official recognition of the global underdevelopment of the domestic recycling and processing industry and the lack of real state participation in its formation and development.

On the issue of building an integrated waste management system: World practice and its application in the Russian Federation

The problem of municipal solid waste (MSW) in the world is increasing every year. According to the World Bank, more than 2 billion tons of municipal solid waste (MSW) are produced annually in the world. The paper shows that problem of waste management is growing all over the world. And if the developed countries have the opportunity to build an effective circulation system, then the developing countries, which are the majority, still solve this problem through open landfills and burial. It shows that only the presence of a balanced comprehensive program of the MSW management system will allow solving the problem of accelerated creation and effective functioning of the modern waste management industry.

Tools for the Involvement of Construction and Demolition Waste in the Repeated Production Cycle

Purpose. This paper aims to analyze and classify construction and demolition waste. It is necessary that this classification not only reflects statistical data on waste generation, but also serves as an information basis for the integrated waste management system (IWMS). The main task of this system is to maximize the involvement of waste in economic recycling and to objectively reflect the technological capabilities of its processing. This is extremely important in the context of the implementation of European waste management principles and the implementation of the National Waste Management Strategy in Ukraine until 2030. Methodology. The article considers the problems of construction waste management within the framework of the National Waste Management Strategy in Ukraine until 2030, which provides for the implementation of measures and principles of waste management, including construction waste. The author analyzes the management problems in the field of construction and demolition waste, which substantiates the need to classify construction waste with the simultaneous harmonization of processing methods and technologies. Construction activities are inextricably linked to the management of various types of resources, among which secondary materials play a key role in the implementation of construction processes. The ability to effectively manage the flows of these secondary resources is critical to ensuring the sustainability and efficiency of construction production. In this context, the study of the importance of managing the flows of secondary resources becomes an integral part of strategies for optimizing construction processes. Findings. Construction waste from the demolition of buildings and structures is unique due to its size and the need to prepare it for primary crushing. This is especially true in the context of implementing the concept of renovation of the outdated housing stock. Various static and dynamic methods of destruction of building materials, in particular, impact and vibration, have been investigated, with dynamic methods being characterized by lower energy consumption. Originality. The work reflects the formation of theoretical and methodological directions based on the use of recycled materials in construction, as well as a comparative characterization of various methods of destruction of building materials. Practical value. The possibilities of recycling construction waste, in particular, their maximum involvement in recycling, which meets the goals of the Strategy of Ukraine, provides 50% of waste recycling.

Current Progress on the Development of the Integrated Waste Management Consent-Based Siting Process in the United States

Consent-based siting is an approach to siting facilities that prioritizes the participation and needs of people and communities and seeks their willing and informed consent to accept a project in their community. The U.S. Department of Energy (DOE) is firmly committed to a consent-based approach to siting one or more spent nuclear fuel management facilities that enables meaningful and inclusive public participation, addresses community well-being and community needs, and centers equity and environmental justice as core values. At present, nuclear energy accounts for 19% of U.S. electricity production and half of the nation’s carbon-free energy. Nuclear energy is key to achieving the Nation’s goal of a 50% reduction in carbon emissions by the end of the decade, 100% clean electricity by 2035, and a net-zero emissions economy by 2050. Nuclear power will be key to achieving the Nation’s goals, as the United States strives to reduce carbon emissions; ensure energy independence; and maintain leadership in nuclear technology, safety, and security. However, the use of nuclear energy also requires an effective, integrated system for safely managing, storing, and permanently disposing of spent nuclear fuel. Since the 1950s, approximately 90 000 metric tons of heavy metal (MTHM) of spent nuclear fuel has been generated from commercial nuclear power generation in the United States. This inventory grows by approximately 2000 MTHM every year. This commercial spent nuclear fuel is currently safely and securely stored at over 70 sites in more than 30 states where it is enclosed in either steel-lined concrete pools of water or steel and concrete containers known as dry storage casks. The United States also has an inventory of noncommercial spent nuclear fuel and high-level radioactive waste, which makes up less than 5% of the total inventory. Management of the Nation’s spent nuclear fuel and high-level radioactive waste is the responsibility of the DOE, under the Nuclear Waste Policy Act of 1982, as amended. This responsibility includes finding sites to store and eventually dispose of this material. Per Congressional direction, DOE’s current activities are focused on establishing a federal interim storage capability for commercial spent nuclear fuel following a consent-based approach. However, a permanent disposal solution for spent nuclear fuel and high-level radioactive waste will still be needed. DOE will apply lessons learned from consent-based siting for one or more interim storage facilities to future siting efforts for other elements of an integrated nuclear waste management system. An integrated waste management system will include consolidated interim storage capacity, a permanent disposal pathway, and the transportation infrastructure needed to move spent nuclear fuel and high-level radioactive waste from nuclear power plants to storage and disposal facilities. This paper describes DOE’s current progress to identify one or more sites to develop a federal consolidated interim storage capability for commercial spent nuclear fuel using a consent-based siting process.

Comparative analysis of waste management system in Meranti Forest Natural Tourism, Balikpapan City, Indonesia

The use of the Meranti Protection Forest area which is developed into a new natural tourism will cause an increase in the number of visitors which can have a negative impact on the environment. And in developing an area into a new tourism, but not having complete infrastructure will further aggravate the condition of the tourist environment in the future. Therefore, it is very important for a new natural tourism area to plan an integrated waste management system so that waste handling in the area can be handled properly and as much as possible. This plan also reflects development towards smart and sustainable nature tourism in maintaining the environment and ecosystem around the natural tourism area. In implementing the plan, the method used is to compare data on existing conditions in the Meranti Forest Nature Tourism area in terms of technical and non-technical aspects obtained through primary surveys with standards or criteria for providing infrastructure in natural tourism areas. The results of this study will show problems from the results of data comparison, which will then be solved based on the level of Urgency, Seriousness, Growth of the problem. The results of this study will be a reference in planning the provision of an integrated waste management system that is in accordance with current and future needs in maintaining the environment in the Meranti Forest Nature Tourism area of Balikpapan City.

A Circular Economy-Based Plastic Waste Management Policy in Indonesia (Compared to China and EU)

Indonesia is a significant plastic waste producer and has more responsibility. In response, the Indonesian government has released several plastic garbage-related policies. However, the policies are viewed as ineffective. Through the circular economy concept, this study examines potential waste management policies for sustainable development by examining existing policies and comparing China's and the European Union's policies. The study shows that Indonesian waste management is highly dependent on the government. The policy affecting many sectors should require synergic participation from the related stakeholders, namely employers, investors, academicians, and civil society. As learned from these two countries, they have regulations related to an integrated waste management system, so there are no overlapping regulations. Furthermore, Indonesian waste management should consider the availability of a market for environmentally friendly items

Digitalisasi Manajemen Bank Sampah Terpadu di Banjar Tegeh Sari, Kelurahan Tonja

Banjar Tegeh Sari, Tonja Village, North Denpasar District, is one of the banjars or groups of residents who have sufficient social capital in waste management. Banjar Tegeh Sari has several activity units directly and indirectly related to waste management, such as waste bank groups, empowered gardens (including bio pore and infiltration wells), and cooperatives. The main problem in waste management at Banjar Tegeh Sari is the need for digitalization and integrated management between the five waste bank groups in Banjar Tegeh Sari and the Manik Galih Cooperative. The aim of integrating and digitizing waste banks is to combine the five groups of waste banks so that recording the amount of non-organic waste becomes more valid and practical while recording the nominal amount of waste in cooperatives. The solution provided is a conceptual model for designing and digitizing waste banks in an integrated manner with cooperatives which will later be called the Tegeh Sari Integrated Waste Management System (SiMaSaDu Tegeh Sari). The target is to integrate and digitize the five waste bank groups into the waste bank management cooperative to make it more efficient and effective.

Community Empowerment Program by PT Pertamina Patra Niaga DPPU Ngurah Rai

This paper seeks to explain the community empowerment program carried out by PT Pertamina Patra Niaga DPPU Ngurah Rai as a commitment in implementing CSR. The community empowerment CSR program is called Eco-Religion Waste Management System Kedonganan Ngardi Resik. The background of the development of this program, namely: the preservation of customs and culture of the community in Kedonganan Traditional Village Bali. The community there conducts prayer activities through canang facilities made of “janur” as an expression of gratitude to Him. After the worship is over, the canang is forced to become a residue that is disposed of in the landfill because the community is not used to sorting waste from the smallest scale. This community empowerment program was developed through the Logical Framework Approach (LFA) model in responding to environmental crises carried out with the Kedonganan Traditional Village Bali community by mainstreaming religious, social, and cultural communities to create an integrated waste management system. This program has succeeded in creating a disciplined community in sorting waste from the household level and processing waste into compost and bio charcoal briquettes that are reused by the community. This program also contributes to reducing environmental impact of reducing greenhouse gas emissions.

Material flow and environmental performance of the source segregated biowaste composting system.

Life cycle assessment (LCA) is performed to investigate the environmental impacts of two alternative approaches in a biowaste management system. The system inventory is based on actual data and on-site sampling for two consecutive years at the mechanical and biological treatment (MBT) facility at the prefecture of Chania (Greece). The facility pertains as MBT for household waste and material recycling (MR) for the recyclable fractions in two different process lines. The mass balances and environmental performance are assessed from waste generation to end-use. The LCA and ReCiPe 2016 methodology estimate the endpoint environmental impacts on human health, ecosystem quality and resource scarcity. The results show that biowaste source segregation in an integrated waste management system not only significantly benefits its recoverability potential it also improves its environmental performance. Impacts on human health (HH) have reduced by 4.6 times, on freshwater ecosystem quality (EQf) by 6.3 times and resource scarcity (RS) usage by 2.5 times when biowaste is combined with compost production and use, material recovery and reprocessing for fertilizer and raw material substitution.
