#### Introduction to the Background and Importance of the Macau Landfill Anti-Seepage  
In the ever-evolving landscape of environmental management, effective quality control within landfill anti-seepage system projects is crucial for ensuring environmental protection and sustainable development. This paper provides an in-depth examination of quality management practices in such projects, shedding light on various aspects critical to success. To better facilitate the understanding of the discussed concepts, Figures 1 and 2 offer visual representations of key components in landfill anti-seepage systems. In the following sections, we will delve into a detailed analysis of these figures to elucidate their significance in the context of project quality management. Figure 1: Location of Macao. Geographical location of Macau (Figure 1): Macau is located in the southern part of China, with geographical coordinates of approximately 22.1987\({}^{\circ}\) N latitude and 113.5439\({}^{\circ}\) E longitude, situated on the western bank of the Pearl River Delta. Neighboring areas: Macau is adjacent to Zhuhai city and is connected to Guangdong Province, located in the Pearl River Delta region. Terrain features: It mainly consists of the Macau Peninsula and two smaller islands, Taipa and Coloane. Location of Macau's landfills (Figure 2):  
Location: The landfills in Macau are typically situated on the Macau Peninsula or the nearby islands of Taipa and Coloane. Geographical layout: Due to limited land resources, landfills might be placed in relatively remote or less developed areas, considering the sustainability of the environment and the community. Environmental impact: The choice of location for landfills in Macau is related to the locations' geographical characteristics and environmental science, requiring a balance between urban development needs and environmental protection. As a special administrative region, Macau's geographical limitations make its land resources particularly valuable. Against the backdrop of urban development and population growth, proper waste management has become increasingly vital. Landfills, being a primary waste disposal method, aim to bury waste materials, but they also bring forth potential issues of environmental pollution and ecological degradation. The significance of anti-seepage system projects in landfill construction has become more pronounced, as they effectively reduce the environmental risks posed by waste leakage, safeguarding soil, and groundwater quality. The anti-seepage system project in the Macau region is designed to ensure environmental safety during waste burial. However, due to variations in geography, climate, and geological conditions, the project faces unique challenges. Therefore, research into quality management for this project is particularly crucial. By delving into quality management methods for anti-seepage system projects, scientific guidance can be provided for project implementation, ensuring environmental health and sustainable development [1]. Figure 2: Location of Macao landfill. Elaborating the Role of Anti-Seepage Systems in Environmental Protection and Sustainable Development  
Anti-seepage systems play a pivotal role in the field of waste management. Firstly, these systems prevent harmful substances within waste from infiltrating the soil and groundwater, thereby averting groundwater pollution and supporting the sustainable utilization of local water resources. Secondly, by minimizing leakage, adverse impacts on the surrounding ecological environment are mitigated, contributing to ecological balance [2]. Based on data from the Macau construction waste landfill, different types of construction waste, such as inert dismantled materials, sea mud, mixed construction waste, and slag, may possess varying physical properties. Some types of waste may pose greater challenges to the landfill's anti-seepage system because they may be more prone to leakage or affect the efficiency of the anti-seepage layer.
