Waste Bank Innovation Management Using Digital Innovation System Management in Cicadas Village, Gunung Putri District, Bogor Regency

Urbanization has led to a concomitant rise in population, giving rise to various socioeconomic and environmental issues. Consequently, trash problems frequently arise in numerous developing nations like Indonesia. Several cities in Indonesia continue to grapple with their deteriorating garbage issues due to heightened output. Therefore, to establish an optimal waste management framework in a given area, developing a comprehensive plan or strategy that becomes the standard for waste management practices is imperative. Waste professionals deem Indoneeds to be more accurate, reliable, and unreliable in terms of amount and composition. These findings have significance for the appropriate planning and decision-making processes in dealing with waste problems at the national, provincial, and city/regency levels. The waste issue in Bogor Regency has once again garnered attention following the inability to transfer 2,400 tons of waste. The escalating nature of this scenario is becoming more worrisome due to the projected rise in trash generation by 2023. This study aims to assess and appraise the operations of a waste bank by implementing novel advancements at the Green Cikeas waste bank, which serves as a trailblazing waste bank in Cigales Village. Efficient administration of digital innovation systems can enhance waste management activities, thereby contributing to community satisfaction. This innovation has the potential to become a standard for digitalization since it introduces a digital innovation system management idea that can be used in any location and significantly enhance job efficiency. One of the primary objectives of managing digital innovation systems is to attain efficiency and optimization in various areas, such as the management procedures of the bank. This study also considers other viewpoints, encompassing management, human resources, economics, social, and environmental dimensions.

How Indonesia’s Cities Are Grappling with Plastic Waste: An Integrated Approach towards Sustainable Plastic Waste Management

In Indonesia, plastic constitutes the second largest component of municipal solid waste; however, 58% remains uncollected. Most plastic recycling depends on informal sectors, accounting for only 10% of the total, leaving the remainder to potentially harm the environment. This paper analyzes how cities in Indonesia have tackled their plastic waste problems from the perspective of the integrated sustainable waste management framework. This study focuses on plastic waste management (PWM) in three cities: Bandung, Yogyakarta, and Magelang. Data were collected from 41 semi-structured interviews, a plastic waste composition data analysis, and site visits. The research outcomes include a comprehensive analysis of stakeholder roles, plastic waste flow, plastic waste composition data, and various challenges in PWM. This study identifies three main stakeholders in collecting plastic wastes: the Department of Environment as the main local government body, community-based waste banks, and private waste management companies. Most recyclable plastic waste is recovered through waste banks and private collection services. In 2022, the predominant types of plastic waste in Bandung, Yogyakarta, and Magelang City were soft plastics, thick plastics, and hard plastics, respectively. The challenges for the PWM stem from various aspects in political, legal, and institutional; environmental; financial and technical; and socio-cultural spheres. Positive trends towards an integrated system are observed, although full integration has not yet been achieved. The research recommends a multi-stakeholder cooperative approach involving municipal authorities, waste banks, and private collectors, responsive to local conditions and emphasizing sustainability aspects throughout waste management stages for a sustainable resource recycling in developing countries.

Decentralized Composting Analysis Model—The Qualitative Analysis Path

The organic fraction of municipal solid waste (OFMSW) is a significant environmental threat, and an economic and social challenge to manage. As such, the efficient treatment of OFMSW is a significant key factor in achieving sustainable waste management. Decentralized composting (DC) offers a new framework of waste management. The DC analysis model (DCAM) proposed in our previous study provides a powerful tool for decision makers, based on the quantification of the DC project characteristics. In this paper, we focus on qualitative analysis as a complementary tool to support decision making in cases where the quantitative analysis is equivocal. The qualitative analysis identifies the main players in the field, the critical stakeholders, and the potential conflicts between them. It also reveals the root problems and the core competencies for the project’s implementation. The DCAM qualitative analysis in the Shefa-Amr case study indicates that unresolved root problems, such as “lack of national regulation”, “clear ownership of the project”, and “lack of ongoing budget” can result in an unsustainable composting system. Countering that, “commitment of the municipality” together with “economic viability” and securing “suitable areas for placing composters” are among the most important core competencies for the effective implementation of DC projects.

Construction Waste Management from Environmental Law Perspective in Indonesia

Several prior studies have linked the relationship between construction activities and environmental degradation. This research focuses on one of the major issues confronting the Indonesian construction industry, namely construction waste management. In practice, construction waste cannot be avoided and thus must be managed properly. Using a descriptive normative legal study approach and a case approach, this research seeks to investigate the practices and conditions of construction waste management as well as the regulatory legal framework related to construction waste management in Indonesia. This study found that the practice of implementing construction waste management varies greatly depending on the understanding and skills of construction business actors, especially contractors and subcontractors. In addition, normative studies show that there is no regulation that specifically regulates the management of construction waste in Indonesia. Therefore, this research contributes by: (1) encouraging the government to make policies that specifically regulate construction waste management, (2) encouraging periodic monitoring and supervision efforts on the implementation of construction waste management, and (3) encouraging the active participation of the community to participate in supervising the execution of construction projects, especially regarding the management of construction waste. Therefore, this study emphasizes the importance of a legal framework for construction waste management in order to realize sustainable construction.

A systems-focused assessment of policies for circular economy in construction demolition waste management in the Aysén region of Chile

This study pairs a recently developed regulatory framework for Chile with a regional case study in Aysén to highlight systems-level pinch points and synergies for the future application of a circular economy framework for construction demolition waste (CE-CDW) management. A qualitative coding process called purposive text analysis was used to extract, aggregate, and structurally analyze causal connections between factors impacting CE-CDW derived from 15 semi-structured interviews with relevant stakeholders in Aysén. Findings highlight recommendations for future CE-CDW policy and practice centering on well-structured and enforceable laws and regulations that can undergird effective stakeholder collaboration, market competitiveness, and infrastructure development.

Selection of municipal solid waste disposal technology using the Analytic Hierarchy Process and Genetic Algorithm for Gulf Cooperation Council Countries

Municipal Solid Waste (MSW) management represents a significant challenge in rapidly urbanizing regions, notably within the Gulf Cooperation Council (GCC) countries. This study focuses on Kuwait, exemplifying the GCC context, to identify the most suitable MSW disposal methods. We integrate the Analytic Hierarchy Process (AHP) with Genetic Algorithms (GA) for a comprehensive evaluation and optimization of disposal options, considering 13 criteria across economic, environmental, technical, and safety dimensions. Five disposal methods (landfilling, controlled dumpsites, composting, incineration, and refuse-derived fuel [RDF] combustion) are analyzed for their fit to Kuwait's unique environmental and socio-economic conditions. The AHP analysis highlights the paramount importance of "Health & Safety of Employees" (19.8%), "Water Pollution" (16.2%), and "Air Pollution Control" (15.4%) as criteria, underscoring a regional prioritization of health and environmental considerations over cost. Composting and RDF combustion emerge as the preferred disposal methods, with AHP-derived priority percentages of 22.7% and 22.3%, respectively. GA optimization further validates these methods as optimally aligned with the regional waste management framework. Conclusively, composting and RDF combustion are identified as the most feasible MSW disposal options for Kuwait, with potential applicability across the GCC, contingent on alignment with local economic and environmental policies. This research provides a critical foundation for policymakers and stakeholders in crafting sustainable, region-specific waste management strategies.

The Management of Food Waste Recycling for a Sustainable Future: A Case Study on South Korea

South Korea has made remarkable progress in food waste recycling through efficient policies. Around 30% of total waste is food waste, with over 90% of it effectively separated and collected. Challenges remain in optimizing biogas production and utilizing food waste for animal feed. The Volume-Based Waste Fee system, initiated in 1995, reduced waste and promoted recycling. In 2005, the ban on direct food waste landfilling further encouraged separation and proper disposal. The Master Plan for Reducing Food Wastes, launched in 2010, led to the nationwide implementation of the Weight-Based Food Waste Fee (WBFWF) system in 2013. Drawing inspiration from Japan’s policies and strengthening them with the WBFWF system, South Korea has evolved its food waste management. It also adapted European policies to enhance its regulations. This review provides a valuable waste management framework for countries seeking to improve their recycling and resource utilization initiatives.

Balancing people, planet, and profit in urban food waste management

Food waste is a complex problem and critical challenge for the sustainable development of circular economies, with interconnected social, environmental, and economic impacts. Supporting the identification of strategies that best minimise these impacts on people, planet and profit, this paper explores the dynamic impacts of food waste management options on the triple bottom lines of sustainable development in urban circular economies. We present a system dynamics model of the urban agri-food supply chain. This model simulates the fluxes of food and food waste throughout the supply chain, as well as their impacts on economy (i.e., costs and benefits for each sector and the broader economy), society (i.e., food insecurity) and environment (i.e., water, energy, and carbon footprints). Using Bristol city in the United Kingdom as a case-study, we evaluate the impacts of seven food waste management options (i.e., reduction, redistribution, animal feed, anaerobic digestion, composting, incineration, and landfilling). The results show that food waste reduction in consumer sectors (i.e., households and hospitality and food services) and redistribution in supply sectors (i.e., primary production and manufacture) offer the greatest benefits for the environment, society, and economy. For the retail sector, both reduction and redistribution options are highly favourable. Although these options can potentially have some adverse economic effects on the supply side due to a reduction in demand, their considerably high benefits make them high-reward, low-risk options. We thus conclude that food waste reduction and redistribution are the only options with a clear triple-win for people, planet and profit. This paper makes a significant contribution by introducing a robust quantitative model and a novel triple bottom line framework for sustainable food waste management in urban circular economies.

Is sustainability a ‘lesson plan’ for preservice teachers? Extent of environmental awareness in the framework of waste management among preservice teachers

Teachers and the would-be teachers are the facilitators of learning who are the first to implant to us knowledge as we aim to instill sustainable development in every facet of our daily operations. Moreover, to realize sustainable development, this research focuses on the extent of environmental awareness in the framework of waste management among preservice teachers in the College of Teacher Education. This study employed a descriptive-quantitative research design with a 30-item survey questionnaire consisting of five different categories to measure the level of awareness of the preservice teacher. It was administered to a total of 250 third year and fourth-year preservice teachers upon which 213 (85.2%) responded. The findings of this study revealed the multifaceted spectrum of attitudes of the preservice teachers that span from pessimism to optimism in relation to waste management practices and environmental concerns. The results suggest that stakeholders consider a diverse range of perspectives when formulating strategies to promote sustainable waste management practices and cultivate environmental awareness.

Comparative life cycle assessment of a novel sustainable road pavement system adopting recycled plastic from PET bottles and carbonated aggregate

Road surfacing is crucial in improving community accessibility and mobility. Adopting sustainable measures is extremely important to prevent the significantly high environmental burdens associated with road pavement systems production. This study presents a comparative life cycle assessment of traditional pavement systems and their sustainable alternatives made and tested at the London South Bank University laboratories. The low-impact pavement mixes proposed herein provide a novel, innovative method for producing sustainable road systems. Unlike traditional approaches, these asphalt mixes utilise materials derived from recycled polyethylene terephthalate (plastics) and carbonated aggregates and are produced at temperatures significantly lower (warm mix).The Simapro software (Consultants, 2023) [1] was used to model the analysed asphalt mixes, and all life cycle inputs and outputs were characterised during the life cycle impact assessment phase into potential impacts using the IMPACT World + Midpoint method. Additionally, an uncertainty analysis employing Monte Carlo simulation was conducted to validate the life cycle assessment findings, reinforcing the robustness and credibility of this study's results. Notably, the assessment shows substantial reductions in the environmental impact of road pavement mixes adopting recycled plastic and carbonated aggregates, with various outcomes. Compared to traditional mixes, Climate Change emissions are reduced by approximately 40 %–60 %, Marine Eutrophication exhibits reductions of up to 30 %, and Freshwater Eutrophication decreases by up to 20 %. These findings suggest that integrating this sustainable road pavement approach can significantly reduce the environmental burdens of asphalt production and give asphalt a pivotal role in tackling waste reduction, carbon sequestration, and achieving Net Zero. Also, the proposed system can positively contribute to the current United Kingdom's (UK) circular policy model by reconsidering current waste management frameworks and integrating more efficient settings.

Developing an Effcient Framework and Mathematical Modelling for Municipal Solid Waste Management in India

An increase in municipal waste has become one of the biggest problems today. Managing waste is a big challenge for every country. Municipal waste management includes transportation and recycling of waste, which needs huge funds. Moreover, significant carbon emissions occur while transporting garbage from one site to another. Thus, this study focuses on reducing the cost due to municipal solid waste (MSW) transportation. The research aims to develop a mathematical model of the supply chain of MSW management. The process of segregation and recycling is also considered in this study. We consider six Indian states and identify the dumping location of the garbage. The study proposes an efficient framework for selecting the segregation hub location and location of MSW treatment plants. The outcomes would be beneficial to achieve an efficient waste management strategy with reduced cost. The numerical simulation results of the model provides the minimum transportation cost as Rs. 4.92 × 106 according to the locations selected for the study. The final strategic decisions is feasible under the constraint sets considered in the model.

Critical Appraisal of Institutional Solid Waste Management: Case Study of Lead City University, Ibadan, Oyo State, Nigeria

By implementing an adaptable sanitary landfill for an efficient solid waste management system any institution can reduce the risk to the environment and public health while promoting social inclusivity and urban sustainability through resource conservation and material recovery. As a result of Lead City University of Ibadan's extraordinary student growth, the university was forced to scramble to find practical solutions to its waste management problems because sustainable development and environmental sustainability are the primary goals of the Sustainable Development Goals (SDGs). The adaptive sanitary landfill was therefore designed on the basis of waste control, which was characterized by the presence of a liner and a leachate collection system to prevent groundwater contamination and a capping system to prevent air contamination. As a result, the management of solid waste beneath the university system was the focus of this experimental study.
 After the waste was sorted, quantified, and characterized, an experimental method was used to measure the four major liquefied gases (LFGs): carbon dioxide (CO2), methane (CH4), ammonia gas (NH3), hydrogen sulfide (H2S), and nitrogen gas (NH3) using a gas monitoring meter. The measurements were taken both before and after the construction of an adaptive sanitary landfill. The concentrations of liquefied gases (LFG) were measured in the morning and afternoon. Adding activated charcoal had the effect of increasing the liquefied gas production. Lastly, adding animal manures resulted in a greater liquefied gas production than when it was not added.
 In order to provide a planning mechanism for creating a cohesive, financially secure, ecologically conscious, and socially inclusive university environment through sustainable waste management, the research project aims to strengthen the basic framework for inclusive waste management through the construction of an adaptive sanitary landfill at Lead City University, Ibadan.

A decision-making framework for landfill site selection in Saudi Arabia using explainable artificial intelligence and multi-criteria analysis

The rapid urbanisation in Abha, Saudi Arabia, especially in the mountainous landscape, makes it necessary to identify the optimal locations for environmentally friendly building complexes. This study introduces a transparent decision making framework for landfill site selection that combines multi-criteria decision making, fuzzy set theory, GIS and eXplainable Artificial Intelligence (XAI). We focused on the complex interplay of geophysical, geoecological and socio-economic parameters and used fuzzy analytical hierarchy process (AHP) for parameter weighting to address the challenges of site selection in mountainous urban centre in developing country. An index map, called the Landfill Site Potential Index (LSPI), was generated, integrating all key parameters to indicate suitable zones for landfill sites. The LSPI was classified into different suitability zones, ranging from very high to very low suitability, using Self-Organising Maps (SOM) in combination with k-means clustering. The use of XAI models, in particular an optimised bagging ensemble model, provided crucial insights into the factors influencing site suitability. The LSPI with a mean value of 0.681 was categorised into five zones, ranging from very low (7.25%) to very high suitability (20.60%). Within the most suitable zone, ten sub-zones were defined for the prioritised development of landfill sites. The model showed high accuracy, with the SHAP and LIME analyses providing a deeper understanding of the global and local determinants of landfill site suitability. This study not only provides a comprehensive and transparent decision-making framework for waste management in developing countries, but also improves the understanding of the critical factors in landfill site selection.

Analysis of Government Policies in Padang City in Food Waste Management at the Household Level

The waste management issue in the city of Padang, particularly the increasing accumulation of household waste, with the predominant composition being food waste, is the primary focus of this research. The research aims to investigate the policies and strategies implemented by the Padang municipal government in managing household food waste. The research method employed is qualitative, involving data collection through interviews, observations, and direct documentation. The research results indicate that the management of household food waste is still integrated within the broader framework of urban waste management. The absence of specific governance for household food waste results in a significant increase in the amount of food waste being disposed of directly in the Final Disposal Site (TPA). The study concludes that: 1) the management of household food waste is intertwined with urban waste management; 2) Specifically, the Padang city government has not yet implemented a program for managing household food waste; 3) The absence of governance for household food waste leads to a high volume of food waste being directly disposed of in the TPA; 4) Specifically, there is currently no program related to food waste reduction.
