Hurling a successful Construction and Demolition Waste (C&DW) recycling operation around the globe is a challenge today, predominantly because secondary materials markets are yet to be integrated. Reducing, Reusing and recycling of (C&DW) have been employed over the years, and various techniques have been investigated. However, the economic and environmental viability of its application seems l...

The roles of both the data collection method (including proper classification) and the behavior of workers on the generation of demolition waste (DW) are important. By analyzing the effect of the data collection method used to estimate DW, and by investigating how workers' behavior can affect the total amount of DW generated during an actual demolition process, it was possible to identify strat...

The construction and demolition waste (CDW), which is produced by the construction process, presents 33% of the total waste stream in European Union in year 2010 (Eurostat 2010). A construction and demolition waste is generated during whole life cycle of construction design phase, realization phase, occupation phase and demolition phase. On the other hand, the sustainable design of construction...

The high contribution of CO 2 emissions associated with pavements has driven research to assess the life cycle of concrete versus asphalt structures and to develop a strategy to reduce the carbon footprint. The life cycle of pavement has been studied with respect to CO 2 emissions in the use phase of concrete as well as after the concrete is demolished. However, only a few have considered the e...

This study was set to elucidate the concatenating effects caused by the transformation of Morogoro Road to accommodate Bus Rapid Transport (BRT) system. The study was conducted from 2013 to 2014 covering demolition, excavation and construction process of the new BRT system. Both field survey and literature reviews were applied, where the real case was taken at a strip between Manzese and Magome...

Demolition of older housing for urban redevelopment purposes benefits communities by removing housing with lead paint and dust hazards and by creating spaces for lead paint-free housing and other community resources. This study was conducted to assess changes, if any, in ambient dust lead levels associated with demolition of blocks of older lead-containing row houses in Baltimore, Maryland (USA...

Whilst vehicular and industrial contributions to the airborne particulate budget are well explored, the input due to building demolition is relatively unknown. Air quality is of importance to human health, and it is well known that composition of airborne particles can have a significant influence on both chronic and acute health effects. Road dust (RD) was collected before and after the demoli...

OBJECTIVE To estimate standardised hospitalisation ratios (SHR) for chronic lower respiratory diseases among demolition and cement workers in Denmark, 1995-2009. DESIGN This is a population-based register study on data from 'the Occupational Hospitalisation Register'. SHR of chronic obstructive pulmonary disease (COPD) was calculated for both demolition and cement workers. SETTINGS Register...

BACKGROUND Building demolition can lead to emission of dust into the environment. Exposure to silica dust may be considered as an important hazard in these sites. The objectives of this research were to determine the amount of workers' exposure to crystalline silica dust and assess the relative risk of silicosis and the excess lifetime risk of mortality from lung cancer in demolition workers. ...
