- ItemSUSTAINABLE SOLID WASTE MANAGEMENT VEHICLE ROUTING PROBLEM CONSIDERING DRIVERS HEALTH STATE AND RISK OF ACCIDENTS(An-Najah National University, 2024-03-04) Snouber, AbedalazizDue to the rapid growth of urbanization, the issue of solid waste management has drawn the attention of society and all stakeholders, because of the harm that will affect citizens and the environment if waste is not managed properly. Our research aims at solving a solid waste management vehicle routing problem that integrates the three pillars of sustainability; environmental, economic, and social. More specifically, our approach intends to investigate the effect of different drivers’ health state on the different parameters in solid waste management networks, by estimating the probability of suffering from work-related injuries, using Markov’s Chain model. In addition, our approach extends the reality of the model by considering different parameters and variables that will improve its practicality, such as including different cost functions. Furthermore, to ensure sustainable business practices, our model aims at minimizing the CO2 emissions resulting from different types of waste vehicles. Also, the social factor was studied by considering drivers’ health condition, minimizing the risk of accidents facing drivers, and minimizing any deviation from balanced workload between drivers. The Non-dominated Sorting Genetic Algorithm (NSGA) was used to solve the developed model, due to its ability to tackle multi-objective vehicle routing problems in general, and Solid Waste Management Vehicle Routing Problems in particular. After solving the proposed model, results revealed the effect of driver’s health states on different cost functions, in addition to the negative impact of high travel distance and waste vehicle load on the health condition of drivers. Sensitivity analyses illustrated how different model variables and parameters interact with each other, in addition to the effect of travel distance and vehicle load on drivers’ health conditions. The execution of this model in the waste management sector yields many advantages for service providers, due to its ability to monitor the health condition of drivers at each node in the network. This results in productive healthy drivers carrying out operations, who can achieve financial success along with a healthy and safe working environment.
- ItemA FRAMEWORK STRATEGY FOR SUSTAINABILITY CONSTRUCTION WASTE MANAGEMENT: CASE OF WEST BANK, PALESTINE(An-Najah National University, 2024-04-06) Hareez, FirasThis study aims to develop a strategic framework for sustainable construction and demolition (C&D) waste management in the West Bank of Palestine. Currently, no regulatory system governs C&D waste, resulting in unsustainable practices like dumping and burning that degrade the environment and public health. Previous research provided initial estimates of waste quantities, but gaps remain regarding generation patterns, stakeholder roles, and barriers. The research uses a mixed-methods approach, including questionnaires with 100 professionals and interviews with 10 interviewees. Secondary data from literature and reports supplements the Analysis. Findings show a lack of on-site segregation and essential management, 35% of the debris was dumped and more than 5% of the debris was burned illegally. Joint Service Councils manage collection and disposal but have limited capacity and funding. Political fragmentation also complicates coordination. Significant barriers include inadequate policies, infrastructure, lack of private sector compliance, and socioeconomic pressures. Study proposes a strategic framework to address these challenges to establish a coordinated C&D waste governance system by 2027. Objectives focus on strengthening regulations, improving on-site practices, developing infrastructure networks, boosting reuse/recycling markets, and creating sustainable financing mechanisms. A phased implementation plan outlines priority actions, responsibilities, and timelines for stakeholders to transition the sector toward sustainability. The framework provides a roadmap to guide reforms and capacity building needed to manage C&D waste responsibly in the West Bank.
- ItemRISK BASED MANAGEMENT OF INDUSTRIAL WASTEWATER IN NABLUS CITY(An-Najah National University, 2024-10-13) Afaneh, AteidIndustrial wastewater is highly polluting the environment if not handled properly, also affect the wastewater infrastructure for both collection and treatment. Most of consumed water is converted to wastewater from residential, industrial, and commercial uses. Industrial wastewater is a critical concern for all industrial settings that lacks the infrastructure to handle such water. Generally, industrial wastewater in Palestine represents a major challenge to the environment and municipal infrastructure, mainly in the industrial cities like Nablus city. This thesis aims at concluding the most appropriate solutions which prevent or decrease the hazards resulted from industrial wastewater on the wastewater infrastructure and its operation. The research utilized the risk based management approach to propose proactive and reactive barriers for industrial wastewater hazards and impacts. Cost Benefit Analysis was used to estimate the costs and benefits for Nablus municipality for each identified barrier. Risk analysis was carried out to explore the hazards and impacts of industrial wastewater on the infrastructure; Wastewater Network (WWN) in Nablus and Nablus- West Wastewater Treatment Plant (NW-WWTP). Risk evaluation was used to priories the hazards through the calculated risk priority number (or degree of severity) to quantify risk. Results showed that industrial wastewater, which had risk priority number of 9 poses a significant threat to the municipal infrastructure. Infrastructure damage and operational inefficiencies were resulted. To reach this thesis's goal, estimated proposed strategies to reduce negative impacts were discussed in risk control approach. After conducting risk cost benefit analysis for Nablus municipality, it is found that awareness and WWN rehabilitation have to be excluded because their proportion Factor (d) is more than 1, but the other barriers should be executed by the municipality. Since equipment insurance barrier has the smallest d which is 0.0036, it has to be prioritized. Then, to execute the remaining barriers from smallest d in ascending order. Finally, risk based management approach and risk cost benefit analysis options are very useful tools to mitigate and adapt hazards to improve the preparedness and response for Local Governmental Units (LGUs), particularly in the field of wastewater management. The results of this thesis should guide the implementation of effective management practices that ensure environmental protection and infrastructure resilience.
- ItemTHE EFFECT OF GREEN SUPPLY CHAIN MANAGEMENT PRACTICES AND SUSTAINABLE PERFORMANCE ON THE CONSTRUCTION INDUSTRY IN PALESTINE: A CONCEPTUAL FRAMEWORK(An-Najah National University, 2024-11-23) Sharqawi, ShurouqGreen supply chain management (GSCM) has been a highly studied topic as it integrates the environmental aspects into traditional supply chain management concepts. As the construction industry is one of the biggest industries worldwide with tremendous and complex activities and influencing parties, greening the supply chain of this industry will enhance the sustainable performance of the companies and parties working within this industry. This study presents an overview of GSCM practices in the Palestinian construction market and explores the relationship between GSCM practices and sustainable performance (SP), considering the effect of institutional pressures as a moderator on this relationship. A conceptual framework was developed according to the findings of previous studies to identify the primary constructs and their indicators. Data were collected through a structured questionnaire and distributed to a random sample; 97 responses were gathered from different stakeholders working in the construction industry in the West Bank. Smart-PLS 4.0 software analyzed the data through partial least squares structural equation modeling (PLS-SEM). The results of this study reveal that GSCM practices, SP, and institutional pressures have high implementation levels among the targeted sample. A significant position relationship was confirmed between GSCM practices and SP. Additionally, it was found that institutional pressures have a negative significant moderating effect on the relationship between GSCM practices and SP. To the best knowledge of the researcher; this study is considered the first study connecting the GSCM practices with the SP, considering the moderating effect of institutional pressures in the construction industry. Additionally; theoretical and practical implications were also included in this study along with a managerial framework. Finally, the study limitations and future research recommendations were covered in the last section.
- ItemGREEN INTELLECTUAL CAPITAL, GREEN INNOVATION AND GREEN TRAINING FOR ENVIRONMENTAL SUSTAINABILITY– EVIDENCE FROM THE PALESTINIAN BANKING SECTOR(An-Najah National University, 2024-10-15) Barakat, AnwaarThe notable incremental demand for environmental performance in the banking sector has created a massive need to examine how green practices influence ecological performance. This study aims to investigate the impact of Green Intellectual Capital (GIC), Green Innovation (GI), and Green Training (GT) on Environmental Performance (EP) in the Palestinian banking sector, providing insights to improve sustainability practices. The sampling plan for this research included selecting 97 managers from 12 different Palestinian banks as the target population, given their direct engagement in green initiatives implementation. A quantitative research approach was used, and data was collected through structured questionnaires. The sample size was determined to ensure a representative group of employees across multiple banks, capturing diverse GIC, GI, and GT perspectives. This sample allowed for using Structural Equation Modeling (SEM) techniques to analyze the relationships between the variables. The findings confirm a strong and positive correlation between Green Intellectual Capital and EP, meaning that the more a bank adheres to environmental principles, the more likely it is to record better ecological results. Moreover, the result proves a positive relationship between GI and EP. This result highlights the importance of innovation activities in maintaining a sustainable environment. The study also stresses the significance of GT in enhancing Green Intellectual Capital and GI and in promoting the culture for ecological development. This study is helpful to policymakers and bank management in Palestine as they can apply some recommendations on sustainable practices in the banking system. The results will help to expand the knowledge of the concept of sustainability in the context of the banking field and provide further groundwork for more investigations of the establishment of sustainable practices in the financial sector.
