In this feature authors discuss recent research findings that are of interest to readers of Beleid en Maatschappij.

Every year, an average Dutch household produces 1165 kilogram of waste. For high-quality recycling of this waste, we need to separate the waste properly, as placing something in the wrong container may jeopardize the whole recycling process. Municipalities are keen to increase the amount of waste that …

The viability of novel network-level circular business models (CBMs) is debated heavily. Many companies are hesitant to implement CBMs in their daily practice, because of the various roles, stakes and opinions and the resulting uncertainties. Testing novel CBMs prior to implementation is needed. Some …

This is a serious game called Re-Organise. It is a cooperative board game about creating closed loops in the circular economy. The game represents an agro-industrial park in which different types of companies aim to use each other's waste streams as a material and/or energy resource. To do so, the players …

Om gemeenten en gemeentelijke diensten te ondersteunen bij het verbeteren van de bronscheiding door bewoners is de Hogeschool van Amsterdam (HvA) maart 2021 een onderzoek gestart, genaamd BASSTA. In dit rapport worden de resultaten van de analysefase beschreven, waarin middels doe-boeken bij 55 bewoners …

This paper evaluates a design procedure which is able to scale one-dimensional quadratic-residue diffusers, with integrated Helmholtz resonators. These acoustic structures can be tuned to room modes while fitting within a specified volume. An algorithmic solver is used to control geometric parameters …

Industrial Symbiosis Networks (ISNs) consist of firms that exchange residual materials and energy locally, in order to gain economic, environmental and/or social advantages. In practice, ISNs regularly fail when partners leave and the recovery of residual streams ends. Regarding the current societal …

The purpose of the model is to explore the influence of the design of circular business models (CBMs) on CBM viability. The model represents an Industrial Symbiosis Network (ISN) in which a processor uses the organic waste from suppliers to produce biogas and nutrient rich digestate for local reuse. …

Samenvatting Klimaatverandering is een belangrijk topic, waar veel overheden en bedrijven actief mee bezig zijn. Nederland streeft ernaar om in 2050 een volledig circulaire economie te hebben en 95% minder CO2 uit te stoten ten opzichte van 1990. Rijkswaterstaat wil hierin vooruitlopen en al in 2030 …
