Methodology for quantification of waste generated in Spanish railway construction works
چکیده انگلیسی

In the last years, the European Union (EU) has been focused on the reduction of construction and demolition (C&D) waste. Specifically, in 2006, Spain generated roughly 47 million tons of C&D waste, of which only 13.6% was recycled. This situation has lead to the drawing up of many regulations on C&D waste during the past years forcing EU countries to include new measures for waste prevention and recycling. Among these measures, the mandatory obligation to quantify the C&D waste expected to be originated during a construction project is mandated. However, limited data is available on civil engineering projects.Therefore, the aim of this research study is to improve C&D waste management in railway projects, by developing a model for C&D waste quantification. For this purpose, we develop two equations which estimate in advance the amount, both in weight and volume, of the C&D waste likely to be generated in railway construction projects, including the category of C&D waste generated for the entire project.


► Two equations for C&D waste estimation in railway construction works are developed.
► Mixed C&D waste is the most generated category during railway construction works.
► Tunnel construction is essential to quantify the waste generated during the works.
► There is a relationship between C&D waste generated and railway functional units.
► The methodology proposed can be used to obtain new constants for other areas.
