Unravelling key factors controlling vivianite formation during anaerobic digestion of waste activated sludge

As a product of phosphorous recovery from anaerobic digestion (AD) of waste activated sludge (WAS), vivianite has received increasing attention. However, key factors controlling vivianite formation have not yet been fully addressed. Thus, this study was initiated to ascertain key factors controlling vivianite formation. A simulation of...

Investigating the flexural strength of recycled cast glass

Currently, tons of high quality commercial glass are down-cycled or landfilled due to contaminants that prevent close-loop recycling. Yet, this glass is potentially a valuable resource for casting robust and aesthetically unique building components. Exploring the potential of this idea, different types of non-recyclable silicate glasses are...

Bottom-up policy support: Using a construction materials model to identify and quick scan circular opportunities

Although the need for a more circular economy is supported by diverse people in both politics as well as in the scientific community, implementation of circular principles in reality is rarely occurring. This study shows how quantitative models can help to develop new policies for enhancing circularity in the construction sector. By means of a...
