More production equals more waste, more waste creates environmental concerns of toxic threat. An economical viable solution to this problem should include utilization of waste materials for new products which in turn minimize the heavy burden on the nation’s landfills. Recycling of waste construction materials saves natural resources, saves energy, reduces solid waste, reduces air and water pol...

Environmental problems have been considered as a serious situation in Hong Kong, in which waste management is pressing harder in comparing with the practices of air, water and noise pollution. Reuse, recycling and reduce the construction materials has been encouraged for many years; however, it is still not used for many construction site activities. In motivating the construction workers to im...

it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...

During the past decades, construction and demolition (C&D) waste issues have received increasing attention from both practitioners and researchers around the world. A plethora of research relating to C&D waste management (WM) has been published in scholarly journals. However, a comprehensive understanding of the C&D WM research is somehow absent in spite of its proliferation. The aim of this pa...

The proper management of oily sludge from petroleum products storage tanks is necessary because inappropriate methods for dredging of tanks may result in high costs and increased environmental pollution. The purpose of the current study is to rank the strategies outlined by strengths, weaknesses, opportunities and threats analysis using data envelopment analysis model, which provides enriched i...

This paper presents for the first time the results of a full life cycle assessment (LCA)1 study for the three most common types of house in the UK: detached, semi-detached and terraced. All life cycle stages are considered, including house construction, use and demolition after 50 years. The results indicate that the use stage has the largest contribution to most environmental impacts. For exam...

Purpose – The purpose of this paper is to focus on optimization of recycling of concrete from lightweight aggregates containing expanded glass and hard polyurethane (PU) and on the issue of importance of environmental management in constructions, to produce the new combination using rest, construction waste of concrete from lightweight aggregates and hard PU new raw components of concrete from ...

In the waste management field and the wider environmental sciences arena, science and regulation have become increasingly uneasy bedfellows. Scientific research should create the bedrock that underpins environmental legislation, shaping its construction, interpretation and implementation. It is the currency of investment in the future of waste management. Society must be assured that scientific...
