Calculations actually show an increase (generally less than 5%) in most impact categories for the Materials and End of Life stages because of extra transportation needs. However, core material separation in demolition operations and its recycling and/or reuse does bring environmental benefits.

Sep 14, 2018 Construction and demolition (CD) waste is a novel, widespread environmental stress that negatively affects environment, organisms and ecosystem. Yet effects of cumulative consequences of CD waste on the fitness and community structure of most underground insects remain unclear. With relatively sessile life underground lasting several years, cicadas can be an important aspect in forest ...

Different demolition procedures, from traditional demolition to total piece-by-piece deconstruction, will naturally lead to different energy consumption and waste generation patterns from the activities themselves, but given the relatively small impor- tance of this sub-stage in life cycle environmental impacts, the differences were ignored.

Feb 01, 2012 Mohamed Osmani, in Waste, 2011. 3 Construction Waste Composition and Quantification. It is difficult to give exact figures of construction waste produced on a typical construction site, but it is estimated that it is as much as 30% of the total weight of building materials delivered to a building site [7].In the United States, around 170 million tonnes of construction and

Apr 22, 2019 In recent decades, because of the massive destruction of old structures, a large amount of construction and demolition (CD) waste has been produced. These waste materials have the greatest volume and weight among solid waste with many environmental problems. Reusing them in concrete as substitute to virgin aggregates is considered an efficient practice unless significant mechanical

The amount of construction waste (CW) at building sites is highly variable, for instance the CW generation index ranges between 50-300 dm3 per square meters of gross floor area. Today there is still a lack of knowledge about variables (building design, construction process, construction technologies, etc.) affecting the CW generation. The objective of this paper is to analyse the influence of ...
