Developing a construction waste management performance calculator for highway construction.

The generation of a substantial amount of construction waste (CW) poses significant challenges to the green transition of highway construction projects. However, the construction industry lacks integration of construction waste management (CWM) practices into the construction process. This paper aims to develop a calculation for assessing the performance of CWM to monitor its effectiveness in highway construction. Initially, this study utilizes the Site waste management plan (SWMP) as a foundation and develops a Construction Waste Management Performed Assessment Method (CWMPAM). The extension of CWM is incorporated into earned value management (EVM) to manage costs, schedules, and the performance of CWM within a unified framework. The functionality and sensitivity of CWMPAM and CWM-embedded EVM are validated through pilot testing and scenario analysis. The research results are computerized into a calculator to facilitate the practical application of CWM, and its validity is tested using random cases. CWMPAM and CWM-embedded EVM prove satisfactory in assessing and monitoring the execution and performance of CWM. The developed calculator simplifies the practical application of the outcomes. Essentially, the developed calculator represents a groundbreaking integration of CWM and construction management, enabling project managers to monitor and compare the CWM performance across different segments of highway construction. Not only does this contribute to the green transformation of highway projects, it also promotes high quality and sustainable development in the construction industry.

Enhancing performance of construction waste management: Factor analysis from the building contractors’ perspectives

With the rapid growth of urbanization, construction projects have surged, increasing construction waste (CW). Effective construction waste management (CWM) is crucial to mitigate the adverse effects of CW on the environment, society, and the economy. This study aimed to identify critical attributes and factors that enhance CWM in building construction. Attributes were initially identified through a literature review and verified by 32 experts. Subsequently, a questionnaire based on the retained attributes was developed, and a survey was conducted with 304 construction professionals from the building construction sector in Cambodia and Thailand. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were sequentially conducted and further revealed five factors with a total of 27 attributes, namely Governance and policies (8 attributes), Materials and equipment (8 attributes), Requirements and specifications (4 attributes), Construction information systems (4 attributes), and Waste collection facilities (3 attributes). This study identified and confirmed the critical attributes and factors in enhancing the contractors’ CWM performance in building construction that are specifically within the 2 R strategy (reduce and reuse) that contractors can fully control on their construction sites. The findings provide empirical evidence to guide contractors in improving CWM in building construction projects. By enhancing all attributes across the five key factors, contractors can minimize CW and reduce the negative impact of construction activities on the environment and society, thereby contributing to sustainable construction practices.

The role of local institutional quality for the digital and environmental transitions in Italy

In this paper we analyze the effect of institutional quality on the so-called Twin transition at provincial level in Italy. To carry out the analysis, we use two proxies for the ecological transition, namely waste management and air pollution, and two proxies for the digital transition, namely ultra-wide band connections and provincial innovative start-ups. All the models are estimated on a panel of 103 provinces with a time dimension that varies for the different dependent variables. We employ Spatial Durbin Model estimator to take into account spatial dependence across provinces. Our findings indicate that the quality of local institutions may have an important role for the ecological transition, but not for the digital transition. Higher levels of institutional quality increase the performance in waste management and reduce the level of local air pollution. Conversely, the estimated coefficient of institutional quality is not statistically significant neither for ultra-wide band nor for innovative start-ups. Institutional quality turns to be significant but negative for the digital transition when dummy variable controlling for the presence of science-oriented university is added in the model specification. These results confirm that the green transition is largely policy-driven and the local ‘institutional environment’ is an essential ingredient for its effectiveness. The driving forces of the digital transition, instead, can be better found in socio-economic factors that depend on the ‘economic quality’ of the local system and its propensity to innovate within larger-scale innovation trajectories.

Adipura: Good Environmental Governance Perspective and Fiscal Challenges

The research emphasizes the effectiveness of Adipura as an instrument for monitoring the performance of local governments in waste management from the perspective of good environmental governance. Focus study on public participation and fiscal challenges. This is a qualitative research. The main data source from the National Waste Management Information System (NSWMIS) and in-depth interviews with central and local government, members of the Adipura Advisory Board, and the communities. Also supported by secondary data relevant to the study. The purpose of research are to determine the extent of the effectiveness of Adipura and to analysis the factors that must be improved to increase its effectiveness. The results indicate that the placement of Adipura as an instrument for monitoring the performance of regional waste management is appropriate, but still needs to be improved because the impact of Adipura has not been maximized in encouraging sustainable waste management in the region. It is necessary to recalculate the components and subcomponents of Adipura, by adding Non-Physical Components, increasing the portion of public participation and fiscal support for waste management.

Investigating the Operational Feasibility of Waste Management at Integrated Waste Management Sites in Balikpapan City

Referring to the Balikpapan City Medium-Term Development Plan for 2021-2026, the percentage of waste transported to the Final Waste Processing Site (FWPS) is 75.45%, which is higher than the percentage of waste management. As of now, there are 2 Integrated Waste Management Sites (IWMS) in Balikpapan, namely MRF and ITF. Based on data from 2019, waste management at MRF decreased by 51.14%. Meanwhile, ITF only utilizes 25.98% - 31.31% of total incoming waste, with the remainder being sent to Manggar FWPS. This decline in performance is also related to the deteriorating condition of approximately 62% of waste management infrastructure in Balikpapan, so evaluation of the operational aspects of waste management becomes a crucial factor in addressing this issue. In addition, the ideal condition of waste management according to standards serves as the main indicator in assessing the performance of waste management. This research aims to evaluate operational aspects of waste management at Balikpapan IWMS by applicable regulations. Analysis methods used are mass balance analysis and operational performance analysis. Research findings show that waste management at IWMS Balikpapan City can reduce the volume of waste in Balikpapan City. However, the operational performance of MRF did not meet established standards, especially in terms of waste removal and processing systems, with a score of 19. On the other hand, ITF is considered sufficient by provisions of PUPR Minister Regulation Number 03 of 2013 and Indonesian National Standard 19-2454-2002 with a score of 23.

Closed-Loop Direct Upcycling of Spent Ni-Rich Layered Cathodes into High-Voltage Cathode Materials.

Facing the resource and environmental pressures brought by the retiring wave of lithium-ion batteries (LIBs), direct recycling methods are considered to be the next generation's solution. However, the contradiction between limited battery life and the demand for rapidly iterating technology forces the direct recovery paradigm to shift toward "direct upcycling." Herein, a closed-loop direct upcycling strategy that converts waste current collector debris into dopants is proposed, and a highly inclusive eutectic molten salt system is utilized to repair structural defects in degraded polycrystalline LiNi0.83Co0.12Mn0.05O2 cathodes while achieving single-crystallization transformation and introducing Al/Cu dual-doping. Upcycled materials can effectively overcome the two key challenges at high voltages: strain accumulation and lattice oxygen evolution. It exhibits comprehensive electrochemical performance far superior to commercial materials at 4.6V, especially its fast charging capability at 15C, and an impressive 91.1% capacity retention after 200 cycles in a 1.2Ah pouch cell. Importantly, this approach demonstrates broad applicability to various spent layered cathodes, particularly showcasing its value in the recycling of mixed spent cathodes. This work effectively bridges the gap between waste management and material performance enhancement, offering a sustainable path for the recycling of spent LIBs and the production of next-generation high-voltage cathodes.

A Bi-objective location-routing model for the healthcare waste management in the era of logistics 4.0 under uncertainty

The purpose of this study is to apply Industry 4.0-based technologies to improve the management of infectious healthcare waste considering location-routing problem and population risk under uncertainty. To achieve this, a decision support system is developed and implemented utilizing a bi-objective mixed-integer linear programming (MILP) model. The bi-objective MILP model improves the performance of the healthcare waste management by applying Industry 4.0 technologies, including electric autonomous vehicles, information sharing system, internet of things (IoT), Global Navigation Satellite System (GNSS), and RFID-tagged waste bags. We develop a multi-objective solution approach by integrating the lexicographic and TH methods. The validity of the model has been established through its implementation in seven hospitals in the city of Karaj, Iran. The results denoted significant improvements in waste collection efficiency, route optimization, and the reduction of contamination risks.

Evaluasi Pengelolaan Sampah Menggunakan Climate Resilient and Inclusive Cities (CRIC) Waste Assessment Tool Kota Palembang

Waste is a problem that cannot be ignored because it is always generated in all aspects of life. The Climate Resilient and Inclusive Cities CRIC Waste Assessment Tool helps in analyzing the current situation in the city and provides important and practical recommendations from both technical aspects, governance, and social issues. The research aims to evaluate urban waste management using the Climate Resilient and Inclusive Cities (CRIC) Waste Assessment Tool based on management technology in Palembang City. A quantitative strategy was used in this research, along with a descriptive and verification research method. Secondary data is taken from the national waste management information system and other literature to fill in the CRIC Waste Assessment Tool application. Data analysis using CRIC Tool covers waste management, governance, economy and knowledge of citizens, GHG emissions. The results of measuring waste management performance with CRIC show that waste management in the city is still low, most of the waste is disposed of uncontrollably, resulting in SLCPs. Waste banks and TPS3R are still lacking. Achievement of waste management to reduce greenhouse gas emissions has only reached 50% of the recommended target. Proper waste handling is still lacking, such as reduced dumping, open burning, and better composting practices. This will support modifications in waste handling from the community, which can support waste management technology development.

The significance of green purchase behaviour: mediating and moderating role of waste management and eco-regulation

This study examines the significance of green purchase behaviour in small and medium-sized enterprises (SMEs) and explores the mediating and moderating roles of waste management and eco-regulation in this context. The theoretical frameworks of resource-based view was utilized to conceptualize the relationships and dynamics between green purchase behaviour, waste management, eco-regulations, and sustainable performance in SMEs. Insights from these theoretical perspectives help in understanding how internal resources, capabilities, external pressures, and institutional factors interact to drive sustainability practices and business outcomes. Using a cross-sectional design, a questionnaire survey was administered to 225 SME owners. Using the Structural Equation Modelling (SEM) technique of Partial Least Squares (PLS), this study empirically analyses the relationships between green purchase behaviour, waste management practices, eco-regulations, and sustainable performance in SMEs. The results confirmed that green purchase behaviour (GPB) positively impacts waste management (WM). Furthermore, WM positively impacts financial performance (FP), social performance (SP) and environmental performance (EP). The results validate the mediating role of WM. The moderating results revealed that eco-regulation (ER) does play a moderating role in proposed relationships. As SMEs worldwide grapple with the imperative to adopt sustainable business practices, this study provides valuable insights and a roadmap for SMEs seeking to navigate the complex landscape of environmental responsibility and social accountability. The findings provide practical guidance for SMEs striving to strike a balance between economic success and environmental stewardship, fostering a holistic approach to sustainability of SMEs.

Impact of the circular economy on waste management performance: The case of the environmental goods and services sector in South Korea

In South Korea, the Framework Act on Resource Circulation (FARC) was enacted in 2016, making the circular economy (CE) related data limited. This study examines waste management performance in South Korea from the perspective of waste reduction and recycling by using environmental goods and services sector (EGSS) data as a proxy for CE data to assess how adopting EGSS data in policies affects waste management. The current study assumes that the use of EGSS data for environmental policy decisions will result in less waste and increased recycling. To test this assumption, this study conducted a descriptive analysis and segmented linear regression using municipal solid waste (MSW) and EGSS data from 1986 to 2021. The results indicated that the adoption of EGSS data only positively affected the recycled amount and recycling rate of MSW, while its effects on the amount of generated and landfilled MSW was not significant.

Economic and environmental benefit of informal waste scavenging at landfill sites: A case study at Bukit Gemuk, Tawau, Sabah, Malaysia

Recycling is an important part of the solid waste management system. However, community engagement in this activity remains relatively low. The presence of a group of individuals engaged in collecting recyclable materials at landfill sites has contributed to improving solid waste management performance. This paper aims to identify the background and activities of scavengers in collecting recyclable items at landfills, as well as the environmental impact of the scavenging activity. This study was based on questionnaires distributed to 46 scavengers in the study area. The Life Cycle Assessment (LCA) method was used to assess the environmental impact of using recyclable materials in manufacturing products. The LCA analysis could identify the contribution of recycled materials to the total savings of carbon dioxide (CO2), methane (CH4), and nitrogen dioxide (N20) by using recycled materials in the production of a new product. According to the study, the majority of those involved in the scavenging activity are immigrants from Indonesia and the Philippines. Despite safety and health concerns, their efforts to earn a living through waste scavenging are extremely valuable. Furthermore, the findings show that their contribution to the collection of recyclable materials cannot be denied. It is because the presence of this group is essential in a country where recycling awareness is low. Furthermore, the indirect contribution to the environment is important, particularly in reducing the use of natural materials in producing new materials. As a result, the government must devise a more effective strategy for recycling programs by involving all stakeholders.

The research aims to determine the implementation of regional regulations regarding waste management in Bungo Regency based on Regional Regulation Number 6 of 2015 and to determine the obstacles in implementing Regional Regulation Number 6 of 2015 concerning waste management in Bungo Regency. This research uses a qualitative method where this research uses descriptive data in the form of written or spoken words from people and observable behavior.The results of the research show that the Environmental Service Strategy in Implementing Regional Regulation Number 6 of 2015 concerning Waste Management in Bungo Regency, which is described as a program for developing waste management performance as program implementers, is a program that was born to answer waste problems and optimize cleaning services and improve environmental cleanliness. and settlements to public spaces in Bungo Regency. In the explanation of the strategy of the Environmental Service in implementing the regional regulation policy, the program for developing the performance of cleanliness management for communication developed by the Environmental Service of Bungo Regency has not been implemented optimally. The obstacle in achieving the implementation of this policy is the rapid rate of population growth in Bungo Regency so that Waste production also increases. Low public awareness is one of the problems faced in implementing this strategic policy related to cleanliness management and the community's obligations towards the environment, namely the lack of public awareness in practice of always throwing rubbish not in the places provided by the Environmental Service. Furthermore, the obstacle in the Environmental Service's strategy in implementing the regional regulation is the inadequate facilities and infrastructure for cleaning management and the next obstacle is the lack of budget owned by the Bungo Regency Environmental Service so that implementing strategic policies is not yet optimal.

A review of extant literature and recent trends in residential construction waste reduction.

The residential construction sector in New Zealand and worldwide is experiencing increased criticism for generating substantial waste that poses environmental concerns. Accordingly, researchers have advocated implementing residential construction waste reduction (RCWR) strategies as a sustainable solution to managing construction waste (CW). This article aims to provide a comprehensive overview of RCWR by analysing 87 articles from the Scopus database using bibliometric and critical review methods. The co-occurrence analysis of keywords revealed five clusters, in which five main themes emerged: (i) waste generation and management performance, (ii) prefabrication and life cycle assessment concepts, (iii) design concepts, (iv) circular economy and (v) decision-making concepts. The findings suggest that sustainable practices such as designing for waste reduction, prefabrication, waste quantification, three-dimensional printing and building information modelling can effectively achieve RCWR. The study also highlights the benefits of RCWR, including reducing environmental impacts, and identifies management, economic, legislative, technology and cultural barriers that affect the implementation of RCWR strategies. These results provide valuable insights to support future policy formulation and research direction for RCWR in New Zealand.

Municipal waste management performance: a focus on Slovakia and its LAU-1 districts

In this paper, we analyse the changes made to the basic EU directive on waste and assess its impact on the waste legislation of EU members. We then examine the Slovak waste strategies/programs that have implemented the EU directive on waste, namely the Waste Prevention Program, the Waste Management Program, and the Envirostrategy 2030. Based on EU waste legislation, the Environmental Strategy 2030 sets the waste treatment aims for Slovakia until 2030. However, it is questionable whether Slovakia will achieve the set goals. Our research indicates that as of 2021, Slovakia’s rate of waste incineration with energy recovery and landfilling rate of municipal waste are below the EU average, while the recycling rate, both for materials and composting and digestion, is higher. In our quantitative analysis, we examine the progress of waste management performance in Slovakia from 2017 to 2021, focusing on the LAU-1 districts. We estimate composite efficiency indicators using the techniques of Data Envelopment Analysis and Malmquist Indices. In accordance with the hierarchy of waste treatment methods, the applied models consider desirable waste operations variables (recycling and incineration with energy recovery) and undesirable waste operation variables (landfilling). Our results reveal significant variations in efficiency across the LAU-1 districts. The average technical efficiency of the 72 districts has improved from 0.714 in 2017 to 0.852 in 2021, indicating that the performance of districts is generally improving and catching up with the best-performing districts. The total performance, as measured by the Malmquist index, has improved by 45.5 %. Districts with access to waste incineration facilities with energy recovery have exhibited higher efficiency scores, benefitting from this advantage.

Assessment of the performance of cruise ship waste management: Case study of the Rio de Janeiro port, Brazil

The significant growth of the cruise ship industry has resulted in economic benefits, but there are also waste management-related challenges. The aim of this case study was to contribute to the research of cruise ship waste management at the Port of Rio de Janeiro. A3 methodology, applied for the first time in this context, was used to create questionnaires to assess the stakeholders involved, revealing that institutional bureaucracy has a negative effect on waste management. In addition, secondary data on unloaded waste, obtained from the transport manifests, showed that 56 % contained reliable information. The main wastes were plastics (57 %), glass (17 %), metal (9 %), and others. With respect to destinations, 41 % were sent to landfills, 55 % recycled and 4 % thermally treated. Only 5 % of cruise ship moorings removed waste at the Port of Rio de Janeiro, attributed to factors such as high costs.

Financial Impact Of Medical Waste Management In Hospital "X" Surabaya

The increase in the volume of medical waste is in line with the improvement of medical waste management performance and compliance with government regulations. Hospitals have another challenge in medical waste management with higher treatment costs that have a direct impact on financial aspects. Based on these problems, this study aims to evaluate medical waste management by comparing the level of hospital compliance with regulations and technical aspects, assessing the generation of medical waste and assessing the financial aspects of recycled medical waste management. The research method is structured observation to collect information and facts in the field so that a systematic description can be accomplished. The results of this study show that X Hospital, Surabaya has complied with the laws and regulations. The results of the study of medical waste generation obtained an average generation in the inpatient room of 88.20 Kg / day and the average waste generation per inpatient patient of 1.15 Kg / day and for outpatients of 0.05 Kg / day. The composition of recycled waste is 18.94%, infectious waste is 57.50%, pharmaceutical packaging waste (Hazardouse waste) is 10.90%, cytotoxic waste is 0,06% and sharps waste is 1.25%. The financial analysis generated from recycling activities on used hazardouse waste packaging, used syringes, used infusion bottles other than blood and/or body fluid infusions, and/or used hemodialysis fluid packaging obtained a NPV value > 0 and BCR value = 1.98 > 1, so this investment is economically feasible and the investment plan is recommended to be implemented.

The Effect of an Educational Intervention Based on an Integrated Social Cognition Model on Waste Recycling at the Source Among Housewives in Lahijan City: A Quasi-Experimental Study

Background: Recycling is proposed as an economic model for saving raw material and energy costs, pollution reduction, reducing waste, resource depletion, and situation improvement in a range of environmental pollution issues. Objectives: The present study aimed to investigate the effect of educational interventions based on an integrated social cognition model (ISCM) on waste recycling at the source among housewives in Lahijan City, Iran. Methods: In this quasi-experimental study, a total of 144 women who sought health care services in Lahijan were selected using a multistage random sampling method. The participants were then evenly divided into intervention and control groups, with each group consisting of 72 women. The study was conducted between 2021 and 2022. Data collection tools included demographic information questionnaires, awareness questions, and ISCM constructs about waste recycling at the source. The total mean scores for the content validity ratio (CVR; 0.84) and content validity index (CVI; 0.83), Cronbach's alpha coefficient (0.85), and internal consistency (0.84) were measured to evaluate the validity and reliability of the questionnaire. Educational content based on ISCM constructs was prepared and carried out in the intervention group in six 60-90-minute sessions virtually via mobile phone using WhatsApp messenger over 6 consecutive weeks. The data were collected before and 1 month after the educational intervention and analyzed using descriptive statistics, Chi-square, independent t-test, paired t-test, and analysis of covariance (ANCOVA) using SPSS version 25. Results: The mean age of the participants was 38.9 ± 12.1 years. Before the study, the 2 groups had no statistically significant difference regarding all demographic variables, awareness, and ISCM constructs (P > 0.05). The 2 groups showed a statistically significant difference in the mean scores of awareness, attitude, subjective norms, perceived behavioral control, self-efficacy, behavioral intention, and action and coping planning after the intervention (P < 0.001). The mean ± SD of the behavior score increased from 17.25 ± 4.96 before the intervention to 25.78 ± 4.95 after the intervention (P < 0.001). Conclusions: The design and implementation of educational interventions based on ISCM have the potential to enhance housewives' performance in waste management and recycling while also increasing their awareness levels.

Use of Partial Least Squares Structural Equation Modeling (PLS-SEM) to Improve Plastic Waste Management

This paper aims to propose improvements to plastic waste management performance via Partial Least Squares Structural Equation Modeling (PLS-SEM) using a survey’s structured questionnaire and hypothesis testing. The methodology has been applied to the metropolis of Salvador, Brazil’s third most populated city, although it can be used for other cities worldwide. All the indicators, constructs, and hypotheses concerning collection, sorting, and recycling came from a literature review. The dependence of the performance on efficiency, effectiveness, the municipality’s socioeconomic aspects, and the municipality’s infrastructure was evaluated, and both academic and practitioner public representatives were surveyed. Since almost double the minimum number of respondents answered the questionnaire and the PLS-SEM statistics showed that the modeling presents consistency, the discussion is relevant. The final results show that the respondents rated the volume of processing to be slightly more significant than the market maturity for the effectiveness of plastic waste management, which in turn contributes to performance. Once the positive influence of the municipality’s infrastructure on performance has also been verified, the Deposit-Return Systems (DRSs) should be considered for improvement, in addition to an increase in the availability of selective collection systems, contributing to the growth of both the recycling rate and business profitability, reflections of performance.
