Containers for material recycling should be set up on-site and clearly labeled. It is important that construction personnel be trained in the material sorting policy, and bins should be monitored periodically to prevent waste mixing as a result of separation mistakes or non-construction personnel using the bins.
Among existing studies on CDW recycling, significant efforts have been made to investigate economic benefits of recycling plant, for example, examining the economic feasibility of CDW recycling ...
The few construction and demolition waste (CDW) recycling plants that there are in Portugal separate the materials and then crush and sieve them prior to final delivery.
1. Introduction. Construction waste is an issue that has attracted increasing worldwide attention recently. With the rapid development of socioeconomic and urbanization in China,
In 2013, there was a total of 23 640 construction works, which is a 12.45% decrease compared to 2012. This corresponds to 16 364 new construction (13.77% decrease), 6 …
Today, recycling of construction and demolition waste (C&DW) by plants is a reasonable alternative to the existing unsustainable disposal methods such as landfilling and fly tipping.
Current state, comprehensive analysis and proposals on the practice of construction and demolition waste reuse and recycling in Portugal March 2022 Journal of Civil Engineering and Management …
Economic viability analysis of a construction and demolition waste recycling plant in Portugal – part II: economic sensitivity analysis ... (Vadde et al., 2007) and CDW recycling operations (Bohne et al., 2008). Although special purpose methods have been developed to perform sensitivity analysis from a general …
Millions of tonnes of glass wastes are produced worldwide, but only marginal is fed back into recycling with majority ending at stockpiles. Though glass wastes are used in the construction industry since decades, there still exists need to recycle this valuable waste product which otherwise could result environmental concerns from excessive …
In Portugal's largest city, Lisbon, the collection of this waste is still not widespread, neither among residents nor among businesses, restaurants and cafes. The goal of launching bio-waste collection and recycling throughout the country is, alas, not realized by the stated date of January 1, 2024.
Although recycling and re-use are good alternatives to waste disposal, in Europe and the USA, for example, only 30% of the total CDW volume is consigned to recycling [13].This rate is even lower in some countries, such as China (5%) [7] and Portugal (9%) [14].In Brazil, a survey carried out in 2011 showed that CDW recycling …
