Construction activity in Europe has increased substantially in the past decade. Likewise, there has also been a commensurate rise in the generation of construction and demolition waste (C&DW). This, together with the fact that in many European countries the rate of recycling and reuse of C&DW is still quite low has engendered a serious environmental problem and a motivation to develop strategie...

It has recently been estimated that 72 million tonnes of Construction and Demolition (C&D) waste arose in 1999 in England and Wales accounting for approximately 20% of total waste arisings. Of this 35% is estimated to be recycled. Improving the efficiency of the construction and demolition industry is a key objective for the UK Government, with the publication of a strategy for more sustainable...

The construction industry faces many problems and challenges especially with the construction of housing which are due to the high level of non-value-adding activities (waste) that reduce the overall construction performance and productivity. In recent years, there have been investigations and research on improving the performance of construction. Lean construction is widely known as an effecti...

Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...

The construction industry is one of the biggest and most active sectors of the European Union (EU), consuming more raw materials and energy than any other economic activity. Furthermore, construction waste is the commonest waste produced in the EU. Current EU legislation sets out to implement construction and demolition waste (CDW) prevention and recycling measures. However it lacks tools to ac...
