Abstract Landfilling is a critical method in managing massive generated C&D waste, and the appropriate selection of C&D waste landfill sites can reduce the impacts of landfilling. This study proposes an approach combined F-AHP and GIS to select suitable C&D waste landfills. The proposed model considers multiple factors from environmental, social and economic aspects. A case study of Shenzhen, China, is undertaken to showcase the implementation of the proposed model. It is found that about 25 million m2 of land has the potential to be used for C&D waste landfills in the study case, but the actual usable land is limited as some lands are too small for a landfill site. The study contributes to the waste management discipline as it provides an improved framework for selecting a landfill site. Besides, the landfill site selection procedure and results have practical implications for urban planning. Keywords Construction and demolition waste . Landfill site selection .

Introduction With the largest and fastest urbanization process in history, the urbanisation rate in China has increased from 19.4% in 1980 to 60.6% in 2019 (NBSC 2020). The large urbanisation in combination with the promotion of urban renewal has led to Responsible Editor: Philippe Garrigues Electronic supplementary material The online version of this article (https://doi.org/10.1007/s11356-020-09951-2) contains supplementary material, which is available to authorized users. * Huanyu Wu [email protected] Zhikun Ding [email protected] Menglian Zhu [email protected] Jian Zuo [email protected] 1

large-scale activities on urban construction and renovation. As a consequence, the generation of construction and demolition (C&D) waste has increased dramatically every year (Ding et al. 2015). It is reported that China generates about three billion tons of C&D waste annually, accounting for 30% of all C&D waste in the world (Zheng et al. 2017). By comparison, the European Union generates over 800 million tons and the USA generates about 700 million tons of C&D waste per year (European Commission 2019; Jain et al. 2015). The massive generation of C&D waste has brought significant environmental issues worldwide (Udawatta et al. 2015; Tam et al. 2018; Wu et al. 2020). Regarding the compositions, C&D waste is a mixture of inert and non-inert solid waste. This type of waste mainly consists of
