“…Based on the project life cycle, starting from design, procurement, storage, and implementation are interconnected, the design factors had the greatest potential to minimize waste and had been highlighted in various empirical studies [19][20]. However, the factors directly related to construction waste contextually are only implementation factors related to design and storage factors.…”

Improper management of construction and demolition waste has massively accumulated waste and has raised concerns over its impact on the environment and natural resources. The aims of this research modeled construction waste management based on the project life cycle, starting from design, procurement, storage, and implementation. The study aims to conduct a more in-depth study related to Construction and Demolition Waste (CDW) management to find the right strategy. The research method was used by identifying variables based on the review literature and compiling questionnaires for 80 construction projects in Indonesia that were randomly selected to be modeled with Partial Least Squares (PLS) tools. Based on specific criteria, existing models and indicators were evaluated against reflective outer models in explanatory research. The final model explains that construction waste has 24 indicators, namely, four at the design stage, eight at the procurement stage, four at the storage stage, and eight at the implementation stage. Based on the initial contextual analysis, the design factors are the main factor causing the waste. However, the final model explains that the construction waste contextually only relates to the implementation stage, but the design and storage stages directly affect the implementation stage. Therefore, strategies in waste management must be carried out, starting with the right design and material storage processes that are by standards to minimize waste at the time of implementation.

“…However, the damage to the environment has been caused by air pollution, climate change, shortage of natural resources, and increasing waste generation, particularly from the construction industry. These constructions contribute ~36% of total waste globally ( 28 ). South Asian countries have a poor history of road construction, while in addition, the construction at hillsides saw rock-falling, landslides, debris flow, snow avalanches, and road closers.…”

The Belt and Road Initiative (BRI) can play a significant role in the sustainable development of South Asia if appropriately implemented. Apart from the economic, trade, and cultural benefits of this colossal infrastructure, less is known about its environmental impact on South Asia. This study looks closely at the potential impact of the BRI on the South Asian environment. This research is based on the government-issued environmental policies, peer-reviewed literature, media articles, and reports. It has been suggested that the BRI could have a negative impact on the South Asian environment, which provided if does not consider the Paris agreement with its partners in the region. The study suggests that partner countries should adopt the BRI project to the principles of environmental impact assessment.

“…Wang et al based on an empirical study, evaluated the waste generation rate of different types of waste at different construction stages by sorting and weighting the construction waste from 148 new-built residential construction sites on-site in China, and they found that the amount of inorganic nonmetallic waste with a generation rate of 16.59 kg/m 2 was the highest among the five types of wastes (i.e., inorganic nonmetallic waste, organic waste, metallic waste, composite waste, and hazardous waste), while the waste generation rate for the underground construction stage, which was 27.57 kg/m 2 , was the highest among the three stages (i.e. underground stage, superstructure stage, and finishing stage) [ 13 ]. He et al calculated the output of CDW in China from 2000 to 2016 by using CDW generation calculation method, and they proposed that China's construction waste generation will increase by 3% each year [ 14 ].…”

Railway engineering generates large amounts of construction and demolition waste (CDW). To quantify the amount of CDW generated from railway engineering projects throughout the whole life cycle, a process-based life cycle assessment model is proposed in this paper. The life-cycle CDW is divided into four parts: CDW from off-site transportation of construction materials (OSTCM), CDW from site operation wastage of construction materials (SOWCM), discard ballast from roadbeds, stationyard, bridges and tunnels (DB), and CDW from reparation and renewal of aging components (RRAC). Yun-Gui Railway is selected as a case study to validate the developed model, and an uncertainty analysis is conducted with Oracle Crystal Ball software. The results show that between 175 and 311 million tons of CDW is generated throughout the whole life cycle of Yun-Gui Railway. DB is the largest component of the life-cycle CDW from railway engineering projects. This indicates the negative environmental impacts of railway construction can be significantly mitigated by optimizing the location of ballast disposal sites and developing suitable landfill proposals. Also, the CDW generated by wastage of construction materials during off-site construction and site operation is important in waste management in railway engineering projects, in which rubble, sand, and cement have the high potential for waste reduction. Findings from this study can contribute to the knowledge body as well as the engineering practice in green railways.
