Discussion on Management Mode of Construction Waste in China

Abstract

Now in China, the management of construction waste still gets less attention than it deserves. The construction waste has caused huge consumption of limited resources and led to serious environment pollution. Consequently; it makes bad effect on China's sustainable development. Firstly, the definition of construction waste is provided in the paper. Then based on the analysis of the present management situation of construction waste, different of management modes of construction waste are evaluated, and then the mode of reducing construction waste from its source is presented, which would performs well to realize the reduction and recycling of construction waste. At the same time, this paper also puts forward the construction model of carrying out corresponding countermeasures; finally, the development trend of construction model in the future is prospected.

Research and Application of Acoustic Emission Signal Processing Technology

“…For various reasons, most of the construction waste is directly transported to the suburbs without treatment and is disposed of by open-air stacking or landfill, which seriously threatens the safety of the ecological environment. In this regard, scholars from all over the world have carried out studies on waste minimization, multiple utilization and harmlessness from the perspectives of waste management methods [11], management mode [12], optimization process [13], recycling [14], [15]. Among waste, construction waste is the most important component of construction waste, including broken concrete blocks, bricks and so on [16].…”

Repulping high wet-strength waste banknote paper by a dual-pH pretreatment process

“…It is difficult to reuse high wetstrength paper due to its poor repulpability in conventional repulping processes (e.g., in a hydropulper). Usually, a large amount of waste high wet-strength paper is either landfilled as solid waste or burned as garbage, which pollutes the environment and wastes fiber resources (Shao et al 2011). In this context, the recycling of wet-strength paper is of great significance (Espy 1992(Espy , 1997Espy and Geist 1993;Darlington and Lanier 1995;Njaa et al 1994;Staib et al 2001).…”
