“…This situation ties down the landfill space, increases the number of illegal dumping and generates social opposition to the environmental degradation caused by the demolition process [3]. For this reason, in recent years, models for managing C&D waste have been developed trying to reconcile economic progress with sustainable construction and demolition projects [4][5][6][7][8][9].…”

“…Specifically, the amount of non-hazardous C&D waste accumulated from reuse, recycling and other recovery of materials should constitute at least 70% of waste production by 2020.Thus, it sets specific measures in terms of 3R regulation for achieving three main objectives: inert waste recovery, eradication of illegal landfills and promoting demand for the recycling of C&D wastes, especially of recycled aggregate. However, there are still outstanding issues of particular relevance such as the prevention of pollution caused by landfills and the creation of ‗green jobs' in this sector [8].…”

“…If all participants involved in the 3R process integrate a successful EMS in their activities, a global environmental culture in the treatment of C&D waste is achieved (Figure 1). The aim of this paper is to investigate the unexplored effects on recycled C&D waste by launching scenarios encompassing policies where dominant feedback loops of the system can be identified and the effects of recycled C&D waste can be maximized [8]. First, we advance the study of different guidelines for the adoption of an effective EMS in Spain with patterns that can be expected in other European countries, especially those with low recycling and reuse levels of C&D waste.…”

According to the recent Spanish legislation, the amount of non-hazardous construction and demolition waste (C&D waste) by weight must be reduced by at least 70% by 2020. However, the current behavior of the stakeholders involved in the waste management process make this goal difficult to achieve. In order to boost changes in their strategies, we firstly describe an Environmental Management System (EMS) based on regulation measures and economic incentives which incorporate universities as a key new actor in order to create a 3Rs model (Reduce, Reuse and Recycle) in the C&D waste management with costs savings. The target areas are focused mainly on producer responsibility, promotion of low-waste building technologies and creation of green jobs to fulfill three main objectives: valorization of inert wastes, elimination of illegal landfills and stimulation of demand for recycled C&D wastes. To achieve this latter goal, we have also designed a simulation model-using the Systems Dynamic methodology-to assess the potential impact of two policies (incentives and tax penalties) in order to evaluate how the government can influence the behavior of the firms in the recycling system of C&D waste aggregates. This paper finds a broader understanding of the socioeconomic implications of waste management over time and the positive effects of these policies in the recycled aggregates market in order to achieve the goal of 30% C&D waste aggregates in 12 years or less.

Abstract-Construction waste is generated throughout the construction process such as during site clearance, material use, material damage, material non-use, excess procurement and human error. The exact quantity and composition of construction waste generated throughout the projects are difficult to be identified as they are keep on changing due to the dynamic nature of the construction activities. Different stages of construction generates different types and composition of waste. Therefore the trend of waste generated throughout the construction stages need to be identified. This paper will critically review literature on construction waste in order to understand the nature of waste generation from construction activities. Based on the literature studied, this paper propose a method to quantify waste for conventional construction. The proposed method comprises four steps. First is identification of construction stages and expected waste generated. Second is selection of construction sites with similar characteristics for uniform investigation. Third is sorting and weighing of mixed waste collected in a dumpster. The last step is summation of the recorded quantity. It is expected that the proposed method should be practical and suits current situation of Malaysian construction projects and support the agenda of National Strategic Plan for Solid Waste Management.

The stone mining and construction sectors are crucial for Thailand's economic advancement. Yet, they face issues such as substantial stone waste accumulation, causing environmental pollution and the resource‐intensive nature of concrete production. Existing studies lack comprehensive coverage of Thailand's specific environmental challenges related to these industries and their sustainable solutions. There is also a knowledge gap concerning region‐specific influences and the relationship between stone dust and concrete sustainability within Thailand's unique geographical and socio‐economic context. Furthermore, sustainable practices in stone dust concrete within Thailand are insufficiently investigated. To bridge these gaps, this study examines the viability of the stone dust concrete business and its potential to mitigate social and environmental challenges. The research reveals alignment between the stone dust concrete business model and stakeholder needs through interviews with industry stakeholders. Subsequently, barriers like the absence of sustainable concrete standards, higher costs, and limited consumer demand for eco‐friendly products are identified.
