“…This growth has contributed significantly to waste generation [3,4,5], which has become a serious problem, as it impacts the economic dynamics and has an important effect on the environment [6]. Several previous studies indicate that waste emerges during the planning, design, procurement, and construction stages [7,8,9]. Construction waste is generally classified into physical waste and nonphysical waste as shown in Figure 1 [10].…”

Construction projects in developing countries often face challenges related to inefficient practices and high levels of waste, leading to cost overruns, delays, and environmental degradation. Lean construction principles have gained attention as a systematic approach to minimize waste and improve efficiency in construction projects worldwide. However, the impact of adopting lean principles on waste reduction in developing country contexts remains a subject that requires investigation. This case study aims to examine how implementing lean construction principles can reduce waste in building projects in developing nations. The research utilizes a mixed-method approach (qualitative and quantitative). Qualitative interviews are conducted with key stakeholders, including project managers, contractors, and architects, to gather their perceptions of the most common type of waste in the construction process and how the lean principle implementation minimizes waste. Quantitative approach: a case study was conducted using a lean simulation model by ARENA software, to measure the impact of lean construction principles on the overall performance of the construction (reinforcement process). One of the key findings in the case study is that the lean model enhances the overall efficiency of processes by eliminating non-value-added activities, standardizing work procedures, and fostering continuous improvement. These practices lead to a reduction in wasted resources, such as the reinforcement process (improvement in overall cutting process by 67.1% and in bending process by 21%) and enhance work productivity by 19.6%, and thus refinement in the overall time cycle by 24.5%. In summary, by adopting lean principles, businesses can create a more sustainable and efficient future while contributing to the overall preservation of natural resources and the environment by focusing on value-added processes.

“…Therefore, it is clear that the construction industry contributes significantly to waste production. 10 To address the issue of increasing C&D waste, various challenges have arisen, including landfill space shortages and rising construction costs. This has led both government agencies and private companies to reduce waste generation.…”

This article discusses construction waste and its management in the territory of Croatia. In order to better understand the concept of waste, the first part of this paper discusses its origin, characteristics, and categorisation. In addition, it mentions special categories of waste defined within Croatian borders. All members of the European Union are encouraged to adopt a circular economy approach to manage these various types of waste. Furthermore, the article emphasises the necessity to construct legal landfills in addition to building management centres, recycling yards, and transfer stations, in order to reduce the formation of wild landfills, which result from irresponsible waste disposal. The second part of the article provides a detailed description of construction and demolition waste. In addition to the types of occurrences and the associated degree of hazard, a categorisation system is used. This system includes records and key numbers, and allows finding the appropriate species in the database with the corresponding key number. Modern technology has made it possible to recycle all types of waste, including construction waste, into secondary raw materials. Proper management is essential to achieve this goal. The first step involves prevention, diversion or conversion of waste into a resource. When these options are not possible, one of the recovery processes should be employed. Managing Construction Waste also provides a comprehensive explanation of recycling, which is given significant attention. The article concludes with an overview of the Republic of Croatia’s system for managing construction waste, which lags behind more developed countries, as well as offers examples of best practices and possible improvements.

“…Construction and demolition waste (CDW) is defined as the MSW from construction, renovation, and demolition processes [4,5]. The scale of construction and demolition (C&D) waste is quite alarming, with over 10 billion tons being generated annually worldwide [6]. It accounts for 35-40% of the total waste generated worldwide [7], and within the European Union and the United States, it accounts for 36 and 67% of the total waste generated, respectively [8].…”

In South Korea, demolition waste (DW) management has become increasingly significant owing to the rising number of old buildings. Effective DW management requires an efficient approach that accurately quantifies and predicts the generation of DW (DWG) of various types, which necessitates access to the required information or technology capable of achieving this. Hence, we developed an artificial intelligence-based model that predicts the generation of ten DW types, specifically from buildings in redevelopment areas. We used an artificial neural network algorithm with <10 neurons in the hidden layer to derive individual input variables and optimal hyperparameters for each DW type. All DWG prediction models achieved an average validation and test prediction performance (R2) of 0.970 and 0.952, respectively, with their ratios of percent deviation ≥ 2.5, verifying them as excellent models. Moreover, Shapley additive explanations analysis revealed that DWG was most impacted by the floor area for all DW types, with a positive correlation with DWG. Conversely, other factors showed either a positive or negative correlation with DWG, depending on the DW type. The study findings may assist demolition companies and local governments in making informed decisions for efficient DW management and resource allocation by accurately predicting the generation of various types of DW.
