Abstract Construction waste typically accounts for roughly 30% of municipal solid waste and thus poses a great challenge to government authorities in almost all cities around the world, especially those in developing counties. To promote the adoption of circular economy and improve construction waste management performance in China's construction and demolition …
The construction waste originating from high-rise and infrastructure buildings may result in a considerable amount of construction materials being wasted at the construction site due to improper disposal [[40], [41], [42]]. Therefore, developing C&D waste recycling strategies to reduce the negative impacts of waste is an important way to ...
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 largest cities were still using primitive disposal ...
With the rapid advancement of urbanization, the amount of construction waste is increasing year by year, which has become an important issue in urban environmental governance and …
In this study, a dynamic material flow model of construction waste is proposed. The area estimation method is introduced to calculate the production of three kinds of construction waste.
In recent years, greenhouse gas (GHG) emissions have become an important issue for all countries, as global climate change problems have become increasingly prominent (IPCC, 2015).The wastewater treatment sector is energy-intensive, consuming large amounts of energy for electricity, chemicals, and mechanical equipment, among other factors, while the …
Treatment of Municipal Wastewater. A common form of wastewater treatment is activated sludge, an aerobic process that exposes microbes to oxygen within the treatment cascade to break down organic waste. 8 Almost 15,000 POTWs treat and discharge over 34B gal/d of wastewater into U.S. waterways. 9,10 1.3M mi of piping flow toward POTWs provide wastewater collection, …
