Circularity and recycling are gaining increased attention, yet the amount of recycled plastic applied in new products remains low. To accelerate its uptake by businesses, it will be useful to empirically investigate the barriers, enablers, needs and, ultimately, requirements to increase uptake of recycled plastic feedstock for the production of new plastic products. During the six focus group sessions we conducted, a value chain approach was used to map the factors that actors face regarding the implementation of recycled materials. The identified factors were structured based on three levels: determining whether a certain factor acted as a barrier or enabler, identifying the steps in the value chain that the factor directly affected and the category it could be subdivided into. The results were then further processed by translating the (rather abstract) needs of businesses into (specific) requirements from industry. This study presented eight business requirements that require actions from other actors in the value chain: design for recycling, optimised waste processing, standardisation, material knowledge, showing possibilities, information and education, cooperation, and regulation and government intervention. The main scientific contributions were the value chain perspective and the applied relevance of the findings. Future studies may delve deeper into the individual factors identified.

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 feedstock for the production of new plastic products. In this research, categorisation is threefold: determining whether a certain factor acts as a barrier, enabler or both; identifying the steps in the value chain which the factor directly affects; and a categorisation in regulatory, economic, technical, systemic, organisational and cultural factors. Results from the focus group sessions show that main barriers seem to be: lack of clear policies and (stimulating) regulations, price differences between virgin and recycle materials, lower material quality and uncertainties about quality, availability and reliable stream of recyclate (from sufficient quality), lack of shortterm organisational goals, lack of knowledge, and lack of consumer demand and willingness. Comparing the results from a micro- and meso scale perspective, some factors are more important for certain steps in the value chain but may also (indirectly) influence the activities of others. Other factors affect all steps of the value chain. Moreover, the relevance of a factor may differ per actor depending on its positioning in the value chain and context, which comes along with uncertainties in industry. Further research may focus on extending literature review and address the needs of industry in order to increase uptake of recycled feedstock in new products.

Our current take-make-dispose economic model faces a vital challenge as it extracts resources from the natural environment at faster rates than that the natural environment can replenish. A circular economy where businesses lower their negative impact on the natural environment by transitioning towards recycling business models (RBMs), one of the four principles of circularity, is suggested as a promising solution. For a RBM to become viable, collaboration among several stakeholders and across several industries is required. In addition, the RBM should be scalable to make a positive impact. Hence, developing RBMs is complex as organizations need to consider multiple principles imposed by the recycling, collaborative, and scalability dimensions of these business models (BMs). In addition, these principles often remain general and not actionable to the practitioners. Therefore, in this study, we researched the practical guidelines for viable RBMs that are also collaborative and scalable. The empirical setting is the reuse of textile fibers to develop biocomposite products. We studied three cases using a research-through-design approach. We contribute to the literature on RBMs by showing the six minimum practical guidelines for recyclability, collaboration, and scalability. We draw implications for within sector collaborations and advance the thought that lease constructs challenge the scalability of RBM.

In het dagelijks leven hebben we voortdurend met verschillende plastics te maken. Overal om ons heen komen we plastics tegen. Denk bijvoorbeeld aan verpakkingsmaterialen, flessen, flacons, kratten, tapijten en plastic draagtassen. Een leven zonder kunststoffen is in onze huidige maatschappij vrijwel ondenkbaar geworden. In 2014 werd er volgens Plastics Europe [1] wereldwijd maar liefst 311.000.000 ton aan kunststoffen geproduceerd, in 1950 was dit nog slechts 1.700.000 ton. Vanaf 1950 stijgt de wereldwijde productie van kunststoffen met gemiddeld 9% per jaar. Bij de huidige productiecapaciteit komt dit volgens Plastics Europe neer op gemiddeld 40 kg/jaar per hoofd van de wereldbevolking! Naar verwachting zal het gebruik van plastics verder toenemen naar gemiddeld 87 kg/jaar per hoofd van de wereldbevolking in het jaar 2050. In Nederland ligt het verbruik momenteel op gemiddeld 126 kg per inwoner. Maar volgens prognoses van VLEEM (Very Long Term Energy Environment Model) [2] zal dit groeien naar gemiddeld 220 kg per inwoner in 2050!! De toenemende vraag naar plastics wordt mede veroorzaakt omdat plastics op zich een gemakkelijk te verwerken materiaal is. Plastics zijn relatief goedkoop, hebben een lage specifieke dichtheid (t.o.v. bijvoorbeeld metalen), en zijn snel en gemakkelijk verwerkbaar.

Plastic is one of the biggest contributors to pollution of the planet. Due to the low recyclability of oil-based plastics, most plastic is being disposed into the environment. According to plastic oceans, 10 million tons of plastic are dumped into oceans annually. Currently, researchers are developing recycling methods for oil-based plastics and are looking for biobased alternatives. One of these alternatives are a class of polymers called polyhydroxyalkanoates (PHA’s). PHA’s differ from other biobased polymers, due to the process of fabrication. PHA’s are a natural polymer, acting as an energy and carbon storage for different strains of bacteria. Functioning as an energy storage, nature can break down PHA’s and PHA-based waste. (1) Different companies are working on PHA’s production, but a large deviations in physical properties were observed. This research aims to establish a relationship between the chemical and physical properties of the different PHA’s, using gel permeability chromatography (GPC), nuclear magnetic resonance (NMR) and gas chromatography-mass spectroscopy (GC-MS).

Wie kent ze niet: “Plastic Heroes”, de grote oranje bakken voor het inzamelen van plastic afval die langzamerhand heel Nederland veroveren. De “Plastic Heroes” campagne is één van de voorbeelden waarmee we de laatste tijd bewust worden gemaakt van het belang van een duurzame levensstijl om er daarmee voor te zorgen dat deze wereld ook voor de generaties na ons nog een goede wereld mag zijn om in te leven. Op het gebied van duurzame materialen kregen binnen het project Materialen in Ontwerp 2 biopolymeren en gerecyclede kunststoffen de aandacht. Dit boekje behandelt gerecyclede kunststoffen en is opgesteld om ontwerpers en bedrijven die zich bezig houden met productontwikkeling praktische (eerste) informatie te bieden hierover. Er wordt uitleg gegeven over de verschillende soorten recycling, voorbeelden van producten, ontwerpregels en de laatste ontwikkelingen op het gebied van 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 uncover how the intersection between issue and exchange fields creates institutional complexity and experimental spaces for business model innovation. Our findings showed a shift in the discourse on circular logic that diverted attention and resources from materials innovation (e.g., recycling) to business model innovation (e.g., circular business models). By juxtaposing institutional complexity and external pressure to maintain legitimacy, we derived four strategic business model innovation responses—preserve, detach, integrate and extend—that illuminate how actors leverage shifting logics and innovate extant business models (for sustainability). We make novel contributions to the literature on organizational fields, business models for sustainability, and business model innovation.

Veel goede bedoelingen, maar geen tempo bij de circulaire transitie. Ruimtegebrek voor grootschalige, hoogwaardige recycling en bouwhubs, en tegelijkertijd onderbenutte ruimte op bijvoorbeeld watergebonden locaties zijn de grootste bottlenecks. Cees-Jan Pen, Juriën Poulussen en Evert Jan de Kort beschrijven negen manieren om ruimte te scheppen voor de circulaire transitie.

The diverse European landscape of climate consciousness is shaped by political values, financial constraints, and country-specific point of view. The aim of the study was to unravel age-specific ecological awareness, forms of engagement, and perceptions, contributing to a nuanced understanding of climate dynamics.Selected regions: Germany (Rheinisches Revier), the Netherlands (Amsterdam Metropolitan Area), and Poland (Upper Silesia/Metropolis GZM) present different states regarding recycling/Circular Economy principles, and different environments.The research design incorporates an inductive qualitative approach to investigate environmental awareness and attitudes toward ecologically friendly behaviors. Six FGIs (Focus Group Interviews) were conducted across three European regions, involving participants from diverse age groups (20–39 years and 40–60 years) in each region.The study shows that ecological awareness varies between countries and generations, reflecting distinctive environmental strategies shaped by cultural and developmental factors. Participants in each region and age group exhibit diverse levels of engagement in sustainable activities, and highlight issues such as the need for tailored strategies, concerns related to eco-labelling, greenwashing, and inadequate waste treatment, as well as information gaps.These variations in pro-environmental attitudes and behaviors across age groups and regions underscore the need for tailored strategies and regional policies. Transparency in waste management, eco-labelling, and sustainable transportation alternatives should be prioritized. Educational initiatives addressing information gaps, especially regarding lifestyle choices, are crucial. Collaboration and interdisciplinary approaches are essential for fostering positive change and a sustainable future across the European Union. Transparent communication, regulatory measures, and accessible eco-friendly options encourage widespread adoption of pro-environmental behaviors.
