The annual construction waste production is approximately 900 MT in the European Union and this accounts to 25–30% of all the wastes ... The composition of C&D waste depends on the location and type of the waste and the demolition techniques adopted to generate it. ... This investigation utilized several ratios (between 100/0 and 50/50) ...
This study conducted a review of a wide array of documents related to construction and demolition waste (CDW) management in Southeast Asia (SEA). CDW definitions, current state of CDW generation and composition, CDW flow and institutional arrangements for CDW management were assessed. CDW generation was estimated in SEA …
The bulk of the studies on landfill leachate chemical composition have been focused on conventional municipal solid waste (MSW) (Ehrig, 1983, Kjeldsen et al., 2002, Kang et al., 2002, Lü et al., 2009, Kulikowska and Klimiuk, 2008, Oman and Junestedt, 2008) and to a lesser extent construction and demolition (C&D) debris (Weber et al., 2002 ...
The treatment of construction and demolition waste can take place in mobile or stationary plants. In the simplest technological variant, as implemented in mobile crushing plants (Fig. 4.1 left), the feed material is first separated into two fractions by pre-screening. The coarse material is then fed to the crusher to reduce the particle size.
Globally, more than 2 billion tonnes of municipal solid waste (MSW) are generated each year, with that amount anticipated to reach around 3.5 billion tonnes by 2050. On a worldwide scale, food and green waste contribute the major proportion of MSW, which accounts for 44% of global waste, followed by recycling waste (38%), which includes plastic, glass, …
The framework proposed determined that an efficient construction waste management plan can be formulated by solving the issues of increasing waste, negative repercussions on ecology of planet, illegal dumping of waste, and …
