“…According to Medina et al, (2014), while some studies (such as Mefteh et al, 2013;Etxeberria et al, 2007) claim that the quality of concrete reduces with increasing recycled concrete aggregate, others (Yang et al, 2011;Thomas et al 2013) argue that the quality of concrete remains unaffected as a result of recycled aggregate. Nevertheless, because construction generates a substantial proportions of landfill waste, and it is still expected to continuously increase (Knoeria et al, 2011), recycling and marketability of waste generated from construction activities is without doubt, a holistic approach to reduce the net amount of waste generated from construction activities.…”

Construction industry consumes about half of all material resources taken from nature, and generates a large portion of waste to landfill. A way of tackling negative environmental impacts impending from continuous material extraction and waste generation is the use of recycled materials for construction projects. However, the use of recycled materials is yet to become a commonplace in construction industry. This study evaluates the factors hampering the use of recycled products in UK construction industry as well as strategies that could be adopted to enhance its use in the industry. In order to identify the impediments and critical strategies, a two-fold methodical approach was used. An unstructured interview preceded a quantitative questionnaire survey which was used to elicit broader industry practitioners' opinion.The study shows that designers rarely specify recycled products. This is due to lack of adequate information about quality and market availability of the products, negative perception from clients, and unexpectedly high cost of the products, despite its perceived low quality. The study suggests that a number of strategies could be adopted to promote the use of the products. These include allocation of points to the use of recycled products in sustainable design appraisal tools, governments legislative measures, improved collaboration between designers, contractors and materials supplier, contractors involvement at earlier stage of design, improved education of the professionals about the products, and the use of tax break to influence the cost of the products. The findings of this study would therefore help policy makers, manufacturers and construction professionals to identify the factors hampering the use of recycled products for construction projects as well as the strategies that could be adopted in order to create market for the products.

“…Indeed, tools, models and techniques have been developed to handle and better manage on-site construction waste segregation (Poon et al, 2001), waste data analysis (Treloar et al, 2003), waste auditing (McGrath, 2001) and reuse (Emmanuel, 2004). At the end of the waste management (Knoeria et al, 2011;Spoerri et al, 2009) and 'hard' technologies (Osmani, 2013) have been developed as a last attempt to divert construction waste from landfill. Consequently, the literature in the field is piecemeal and by and large deals with waste that has already been produced -there is insufficient effort and no structured approach to address waste at source and specifically 'design waste'.…”

Citation: OSMANI, M., 2013 An ever-increasing amount of global research on construction waste has been conducted over the past two decades, ranging from 'soft' mapping and management, reduction tools and methodologies to 'hard' material and recycling technologies. However, the current state of research is largely dominated by endeavours to manage waste that has already been produced. Hence, there is a need for a shift from 'end-of pipe' solutions that focus on on-site waste management to a source-based approach that is aimed at 'life cycle' analysis. This research engaged a sample population from the major UK architectural and contracting firms through 24 interviews to investigate the underlying origins, causes and sources of waste across all project life cycle stages. Respondents reported that designing out waste has never been the most glamorous end of sustainable design. Moreover, the results reveal that waste generation is affected by a wide practice of not embedding waste reduction in briefing and contractual documents, no baseline setting, and lack of designers' understanding of design waste origins, causes and sources. This is hindered by limited know-how and incoherent coordination and communication between project members and impeded by time constraints and disjointed design information. Collectively, these impediments disallow the consideration, engagement and implementation of designing out waste.

“…Changing the mentality of society and engineers will allow treating the waste not only as an environmental issue, but also as an important source of industrial raw materials. Introducing the idea of the closed-loop economy that involves closing the product's life-cycle may result in a reduction in the amount of waste that needs to be deposited in landfills [4][5][6].…”

The Use of Heat-Resistant Concrete Made with Ceramic Sanitary Ware Waste for a Thermal Energy Storage

Abstract:The paper presents the results obtained in the course of a study on the concrete made of aggregate obtained from wastes of sanitary ceramics. Previous examinations proved high in strength and durability of concrete of this type, and it showed a resistance to high temperatures. The material was classified as a fireproof concrete. While searching for the optimal applications of such concrete, a series of examinations and analyses on its thermal energy storage (TES) properties were performed. This paper describes the two-stage experiment on the thermal behavior of the concrete made with sanitary ceramic wastes during cooling processes in comparison to different building materials subjected to the same thermal conditions. On the basis of the thermal, infrared analysis, and suitable calculations, the thermal power and the ability of the composite to store thermal energy was estimated. Finally, it was stated that the concrete made of sanitary ceramic waste aggregate and alumina cement can be recommended as a heat-accumulating material, and in combination with high durability can be used, e.g., for the construction of fireplace bodies.
