“…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].…”

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.

“…The construction industry have been challenged by the unacceptable levels of waste generation over the years [1] Today, the construction industry has become increasingly aware of the importance of both economic and environmental impacts associated with waste generated during both the construction of new buildings and the demolition of old structures [2]. This is as a result of the significant amount of construction and demolition (C&D) waste generated which as huge impact in contributing to environmental damage both nationally and internationally [3,4].…”

“…Today's concept of sustainability embraces all these ideas and maybe more, as the society at large pursue integrated approaches to green initiative [10]. The idea of sustainable development seems to be the best practice solution to managing C&D waste within the construction sector in order to enhance the durability and use of recycled materials as well as eliminating the development of building waste throughout the construction life cycle [1]. The significant improvement in construction site practices worldwide have led to C&D waste reduction through the reuse/recycle operations.…”

ABSTRACT:The handling of wastes remain a perpetual problem, all construction and demolition works and activities are confronted to this issue. Many investors, clients, construction and demolition professionals consider C&D waste management one of the most essential green construction practices in support to energy efficiency. In fact, there is a growing interest in sustainable waste management as potential stakeholders are pursuing innovative and integrated waste management and environmental strategies. Sadly, most traditional approach to reducing C&D waste is considered to be unsustainable as it lacks flexibility and long-term reliability. Thus, the move to a more sustainable society requires sophisticated approach to manage C&D waste, which incorporate feedback loops and focus more on processes, embodies adaptability and diverts waste from landfill disposal. This paper review current C&D waste management practices and propose a conceptual framework for optimising C&D waste management. The study adopts a Life-cycle (LCA) model based on C&D waste sustainability measure (LCASM) to justify the need for a green approach to C&D waste management. The central focus of the LCA model is to minimise C&D waste disposal and to enhance the application of 3Rs (reduce, reuse, recycle) concept. The study sought to determine whether this sustainable approach to C&D waste management is an opportunity or a new challenge. Recommendations are provided on how to enrich C&D waste management optimisation processes.

“…For example, a selective demolition implies that waste separation is carried out, both before and during demolition, in order to prevent material mixing and contamination. However, the economic savings derived from selecting the debris during the demolition process are yet to be studied in depth [13].…”

“…From this standpoint, economic instruments for minimizing construction waste can be employed to encourage waste-prevention efforts, to discourage the least desirable disposal practices, as well as to prevent the negative consequences of environmentally unfriendly treatment and disposal practices of construction waste materials [5]. In order to both minimize the amount of C&D waste entering landfills and to reduce the construction project cost, a good waste management plan is needed in order to properly treat waste, by preventing mixtures and deterioration [6,7].…”

Eco-efficient rehabilitation of buildings and neighbourhoods should include strategies to reduce the potential environmental impact of buildings under consideration for demolishment. In this case, good construction and demolition (C&D) waste management can represent a doubly eco-efficient approach: advantage is taken of much of the building and the volume of waste is reduced during construction and demolition work.Construction and demolition waste management in emergency situations is a subject yet to be studied in the construction sector. This kind of work, although not very common, involves major building damages and the need for punctual, partial or total demolitions. The amount of C&D waste can be a major problem to deal with, and its management during the critical first phases can determinate the progress of the rehabilitation.Conditioned by a greater number of factors than normal construction works, the lack of time for the identification, quantification, and evaluation of C&D waste renders this type of extremely useful study.In this work, from the case study of the emergency repair of a residential building of 40 dwellings in Seville (Spain) seriously affected by a soil displacement, Generated C&D waste are identified and the waste reduction techniques used are shown. These techniques contributed to achieve the planned objectives and to control in advance the cost.Finally, the most important data, C&D waste quantification and the managing cost are presented in order to serve as reference for similar circumstances in the future because there areno clear references to be used.
