This study investigates the process conditions required for the scalable production of NPK 5-10-30 using sewage sludge ash as a recycled phosphate source for fertilizer production. Although sewage sludge ash offers strong potential for circular phosphate recovery, its industrial implementation remains …

Minder zorgafval? Het kan! Nederlandse ziekenhuizen produceren dagelijks grote hoeveelheden afval, vooral door het gebruik van eenmalige medische producten (disposables). Ons onderzoek toont aan dat duurzamer werken mogelijk is zonder grote systeemveranderingen of extra kosten – vaak leidt het zelfs …

Nederland heeft de ambitie om in 2050 een circulaire economie te realiseren: een economie waarin alleen gebruik wordt gemaakt van hernieuwbare en gerecyclede de materialen die al in omloop zijn, in plaats van het verbruiken en deponeren van materiaal. Dit betekent dat de techniekstudent niet om circulair …

The catalytic conversion of oleic acid to aromatics (benzene, toluene, and xylenes, BTX) over a granular H-ZSM-5/Al2O3 catalyst (ϕ 1.2–1.8 mm, 10 g loading) was investigated in a continuous bench-scale fixed-bed reactor (10 g oleic acid h–1). A peak carbon yield of aromatics of 27.4% was obtained at …

This communication aims to provide a framework on how to integrate the concept of Circular Economy (CE) when addressing real-life urban challenges such as resource scarcity, greenhouse gas emissions, pollution, waste, and high consumerism (Williams, 2019), through delivery of courses to students of various …

Bulk molding compound (BMC) thermoset (bio) composites are difficult to recycle because they cannot be melted for reprocessing. However, this group of materials is often used in high-end applications where strength and lightweight materials are required, such as boat hulls, aircraft parts, car parts, …

In this chapter, the central question is which core activities you will undertake in order to achieve your goal, organizing your value proposition with success. Because you are working towards a specific goal, and with selected strategies, it is useful to state which (core) activities are necessary to …

Management of fashion (related) companies need to become convinced that circularity delivers positive financial results and incentives. This research aims to provide the first information requirement insights needed to enable the transition to a circular fashion industry. Due to easy access and abundant information …

Circularity and recycling are gaining increased attention, yet the amount of recycled plastic applied in new products remains low. To accelerate uptake by businesses, it will be useful to empirically investigate the main barriers and enablers that organisations experience when using recycled plastic …

The textile trading system is based on the ‘take-make-use-dispose’ linear economic model: as high amounts of resources are utilized at low costs, the final products become waste after being used for a only short period. This creates an unbalanced system that has to change. A circular economy model can …
