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 …

The contemporary use of resources in the ‘take-make-waste’ economy accounts for 70% of global greenhouse gas emissions, demonstrating unsustainable patterns of consumption and production. Therefore, the status quo of business operations needs to be changed. This study aims to find out how a circular …

Positioning paper bij de inauguratie van Vincent Voet als lector Circular Plastics.

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 …

Implementing circular urban supply chains is a major economic transformation that can only work if significant coordination problems between the actors involved are solved.  This requires, on the one hand, the implementation of efficient urban collection technologies, where process industries collaborate …

This research contributes to understanding and shaping systems for OFMSW separation at urban Small and Medium Enterprises (SMEs, such as offices, shops and service providers). Separating SMEs’ organic fraction of municipal solid waste (OFMSW) is both an opportunity and a serious challenge for the transition …

Accumulation of non-degradable plastic waste in the environment might be prevented by the use of biodegradable polyhydroxyalkanoate (PHA). In this study, the thermophile Schlegelella thermodepolymerans produced up to 80 wt% PHA based on dry cell mass. The largest PHA granules were found in the cells …

This paper presents challenges in city logistics for circular supply chains of e-e-waste. Efficient e-waste management is one of the strategies to save materials, critical minerals, and precious metals. E-waste collection and recycling have gained attention recently due to lower collection and recycling …

We aim to understand how actors respond to field logic plurality and maintain legitimacy through business model innovation. Drawing on a longitudinal field study in the fashion industry, we traced how de novo and incumbent firms incorporate circular logics in business models (for sustainability) and …
