Zhao, Lingqin (author), Zhang, Dongming (author), Hu, Yanjun (author), Guo, Qianqian (author), Jiao, Long (author), Zhou, Nan (author), Di Maio, F. (author)The bottom ash is increasingly used as a substitute aggregate material in road construction in China, and road salting is the major salt source in groundwater. Continuous rainfall releases soluble salts from the bottom ash subgrade into the surrounding soil and groundwater, resulting in potential hazards. Different methods were employed to...journal article 2023

Megevand, B.P.N. (author), Cao, Wen-Jun (author), Di Maio, F. (author), Rem, P.C. (author)This paper aims to summarize, propose, and discuss existing or emerging strategies to shift towards a circular economy of materials. To clarify the landscape of existing circular practices, a new spectrum is proposed, from product-based strategies, where entire products go through several life cycles without being reprocessed, to material-based...journal article 2022

Zhang, Chunbo (author), Hu, Mingming (author), Di Maio, F. (author), Sprecher, B. (author), Yang, Xining (author), Tukker, Arnold (author)The construction sector is the biggest driver of resource consumption and waste generation in Europe. The European Union (EU) is making efforts to move from its traditional linear resource and waste management system in the construction sector to a level of high circularity. Based on the theory of circular economy, a new paradigm called waste...review 2022

Schraven, D.F.J. (author), Bukvić, Uroš (author), Di Maio, F. (author), Hertogh, M.J.C.M. (author)Recent literature has recognized the difficulty of implementing Circular Economy (CE) in supply chains. This has not yet led to a clear understanding of the reasons. This is critical to address, because the difficulty stalls the CE transition and suspends its benefits. Therefore, this paper investigates the reasons for the difficulty of...journal article 2019
