“…Wang et al (2014), Yuan (2011), Ekanayake andOfori (2004) and Osmani et al (2008) state that some aspects of project design indirectly contribute to on-site waste generation. According to the results of the questionnaire (Table 10), it is common during the design phase to consider the future reuse and/or recycling of construction elements and materials (x =3.88; σ=0.97), and to introduce elements and materials from earlier buildings (x =3.70; σ=1.06).…”

“…Although awareness is ranked as one of the most significant success factors for conducting effective C&D waste management (Lu and Yuan, 2010;Osmani et al, 2008;Begum et al, 2009), a lack of training and environmental awareness was also attributed to all project stakeholders (i.e. executive managers, technicians, site managers and workers).…”

“…Most of the studies focused on describing models for the design stage to estimate the volume of C&D waste that will be generated on a site (Mañà et al, 2000;Solís-Guzman et al, 2009;Martínez et al, 2010;Llatas, 2011;Marrero et al, 2011;de Guzmán et al, 2012;Villoria et al 2012). In other initiatives, such as those led by Ortiz et al (2010) and Mercante et al (2012), the research was based on life cycle assessment. Rodríguez et al (2007) analysed how environmental management systems contribute to the generation and management of C&D waste.…”

In this paper, the implementation of effective waste management practices in construction projects and sites is analyzed, using data from a survey answered by 74 Spanish construction companies based in Catalonia. Most commonly implemented practices were found to be on-site cleanliness and order, correct storage of raw materials, and prioritization of the nearest authorized waste managers. The least widespread practices were the use of a mobile crusher on site, the creation of individualized drawings for each construction site, and the dissemination of the contents of the waste management plan to all workers, to help them to meet its requirements. Waste regulations for construction and demolition, and the corresponding construction waste management facilities, were designed before the recession in the Spanish construction sector. Current waste generation rates are still below predicted levels, and the infrastructure was designed for five times more waste generation. Even so, the percentage of reused and recycled waste currently amounts to 43%. Survey respondents highlighted various instruments and measures that would make the management of construction and demolition waste more sustainable. Most of the opportunities identified by construction firms are within the scope of government and related to a combined system of bonus and penalties and the establishment of environmental awareness and training programmes for all the stakeholders. Within the scope of authorized waste managers, firms suggested improvements such as the standardization of fees, a reduction of the time until the issue of waste management certificates, a higher number of inspections, and a change in the current model of a few large construction waste management facilities. This research is useful to better understand the current status of construction and demolition waste management in construction projects and sites. Thus, the results of this research will guide policy makers and relevant stakeholders such as contractors, clients, architects and engineers to achieve the EU target of recovering 70% of construction and demolition waste in 2020. In this sense, reliable information can help governments and professional associations to set future C&D waste management regulations, training programmes and dissemination tools, inspections, etc.Peer ReviewedPostprint (author's final draft

“…With respect to the EoL phase, in Spain most of the waste is currently disposed in landfills, thus occupying a volume which clearly exceeds the volume occupied by domestic waste [54]. However, directives and legislation to reduce and manage building and construction waste have been drawn up both at the European level and at the level of the Member States.…”

The renovation of existing buildings provides excellent opportunities for an effective reduction of energy consumption and greenhouse gas emissions but it is essential to identify the optimal strategies.

Abstract. Landfill is essential in the management of municipal solid wastes in Malaysia. The role of a landfill site has become prominent with the increasing quantity of municipal solid waste. However, the selection of a landfill site has always been one of the crucial yet complicated parts in constructing a landfill. Due to the negative impacts that caused by a landfill site, an appropriate landfill site is required in order to minimize the negative impacts to the lower. Therefore, this paper probes into the challenges in landfill site selection in Peninsular Malaysia. This research is conducted through the reviewing of past similar research and case study with eight different government departments that have play a role in evaluating the suitability of a site to be used as landfill. The results obtained show the challenges in selecting a landfill site. Through the understanding of the landfill site selection, it enables future research to improve the current landfill site selection system and ensure its sustainability.
