Wilson, Stanford (author), Rem, Nils (author), Schielen, R.M.J. (author), Snoek, Yvo (author)River managers today are faced with the challenge of adapting to climate change while also having to sustainably secure all important functions in a healthy river system for society. Nature-based Solutions (NbS) have proven themselves effective across a multitude of contexts; providing integrative approaches for river restoration, conservation...abstract 2024

Vahidi, A. (author), Gebremariam, A.T. (author), Di Maio, F. (author), Meister, K.R. (author), Koulaeian, T. (author), Rem, P.C. (author)The construction industry urgently requires a resilient information system for effective coordination of data transmission among various stakeholders, including both the public and private sectors. Such an advanced digital solution would not only enhance transparency along the value chain but also improve both the quality of and confidence in...journal article 2024

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

Chang, C. (author), Di Maio, F. (author), Rem, P.C. (author), Gebremariam, A.T. (author), Mehari, Fanuel (author), Xia, Han (author)To upcycle End-of-Life (EoL) concrete from demolished buildings, it is essential to efficiently identify the different materials that may contaminate it. The precise identification and classification of materials and contaminants are vital processes for in-line quality inspection of recycled concrete aggregates transported on a conveyor belt....journal article 2022

Kosse, J.J. (author), Dhallé, M. (author), Rem, P.C. (author), ter Brake, H.J.M. (author), ten Kate, H.H.J. (author)In this article, electromagnet layouts are presented, which generate a magnetic field with a magnitude gradient that does not vary significantly in a horizontal plane but decreases monotonically with the vertical height above the magnet. Such a one-direction magnetic field gradient is a specific requirement for magnetic density separation ...journal article 2021

Kosse, J.J. (author), Dhallé, M. (author), Tomás, G. (author), Rem, P.C. (author), ter Brake, H.J.M. (author), ten Kate, H.H.J. (author)This article discusses the optimum layout of coils of a superconducting magnet system for magnetic density separation (MDS). MDS is a novel separation technology that combines a vertical magnetic field gradient with a ferrofluid to separate mixtures of non-magnetic particles based on their mass density. The MDS process can separate more than...journal article 2021

Wen, P. (author), Lohlefink, C.G.K. (author), Rem, P.C. (author)Can random deposition create dense non-overlapping material feeding? The question is very fundamental for the research of particle packing, while the answer is of great importance for any industrial process that applies single object operation. To gain an insight into this issue, we studied the overlap problems of convex particles in the...journal article 2021

Gebremariam, A.T. (author), Di Maio, F. (author), Vahidi, A. (author), Rem, P.C. (author)Currently, natural resources are consumed at an alarming rate than their production (United Nations Environment Programme, 2014). This imposes unprecedented pressure on the environment. The problem seems to get worse with the present increase in population and demand for infrastructures. To alleviate these and other related problems, a circular...journal article 2020

van Engelshoven, Y.D. (author), Wen, P. (author), Bakker, M.C.M. (author), Balkenende, R. (author), Rem, P.C. (author)An innovative route for plastics recycling is proposed, based on a combination of a logarithmic sorting process and colour plus high-resolution near-infrared (NIR) sensors. Although counterintuitive, it is shown that such a technology could sort clean flakes from rigid packaging waste into a very large number of different plastic grades with...journal article 2019

(author), Witkamp, G.J. (author), van Loosdrecht, Mark C.M. (author)To prevent eutrophication of surface water, phosphate needs to be removed from sewage. Iron (Fe) dosing is commonly used to achieve this goal either as the main strategy or in support of biological removal. Vivianite (Fe(II) <sub>3</sub> (PO <sub>4</sub> ) <sub>2</sub> * 8H <sub>2</sub> O) plays a crucial role in capturing the phosphate, and...journal article 2019

Lotfi, Somayeh (author), Rem, P.C. (author)One of the massive by-products of concrete to concrete recycling is the crushed concrete fines, that is often 0 - 4mm. Although the construction sector is to some extent familiar with the utilization of the recycled coarse fraction (>4 mm), at present there is no high-quality application for fines due to its moisturized and contaminated...journal article 2016
