Reduction at the source for new building construction involves both design concepts and building technology/materials selection (Poon and Jaillon, 2002). Prefabrication has been identified as a solution to reduce waste arising during design and construction phases. Hong Kong is a compact city with a...
The study's lean modeling results has led to a 13% reduction in construction cycle time, a 141% improvement in process efficiency, a 268% enhancement in average productivity, and a 96% reduction in labor cost. The result has become the reference document resource for the managers and ...
In order to enforce reduction of CDW, it is necessary to reinforce the source control. For example, building design and construction stakeholders should sign an agreement to develop green construction programs in which they jointly manage the CDW. Enhanced supervision and management is in urgent ...
Composition analysis of construction & demolition waste and enhancing waste reduction and recycling in construction industry in Hong Kong In 2000, Hong Kong generated as much as 37,600 tonnes of construction waste every day. Of which, about 30,200 tonnes of C&D material was transported to the pu...
A significant development in solid-waste treatment and disposal practices was marked by the construction of the first refuse incinerator in England in 1874. By the beginning of the 20th century, 15 percent of major American cities were incinerating solid waste. Even then, however, most of the ...
Cook County,Illinois, recently brought the elimination of construction waste to a new level by creating the first demolition debris ordinance in the Midwest. This groundbreaking ordinance requires most of the debris created from demolition to be recycled and reused instead of being sent to the landfi...
The storage of resources and the reduction of waste are increasingly important things to consider in a sustainable construction sector. Minimizing waste means avoiding, eliminating or minimizing waste at the source of the cause, or using / recycling waste for useful and safe purposes [13]. Efforts...
In disposal environments, the pH will be initially determined by the groundwater chemistry but may vary with time due to the evolution of the groundwater in contact with the waste form, the engineered barrier and construction materials. Accelerated dissolution by increasing the ratio of glass ...
Meanwhile, such an idea of waste reduction is implemented in all areas of the event, including green accommodation, frugal catering, paperless events, and renewable materials, integrating the concept, behavior, and model of zero waste into the entire event from the preparation to the future use ...
Therefore, not only the export reduction scenarios, but also the recycling rate promotion scenarios improved the current situation, mainly reflected by the capability of reversing the impact of GW. The combination scenarios, as optimization, balanced the impacts of these two scenarios. “Half of ...
