Circular Composites

Composites are increasingly used to optimize the performance of applications as their properties can be tuned to achieve the desired functionality. The sustainability advantages during the use phase are not yet matched by lower impacts in the lifecycle of composite materials and products. In a circular economy this is problematic. This book will serve as a guide to designers who want to contribute with innovative and effective solutions. Circular recovery strategies, ranging from reuse to restructuring and recycling, are connected to the design process and concrete design approaches. By providing clear design guidelines and illustrative examples in a structured way the information is readily accessible and applicable to designers

Circular Composites by Design: Testing a Design Method in Industry

The design of composite products for a circular economy is challenging. Materials such as glass-fibre-reinforced plastics have long product lifetimes but are hard to recycle. For the effective reuse and recycling of products, parts, and materials, recovery strategies must be selected and implemented in the product design stage. This extends the scope and complexity of the design process and requires additional skills from the designers. We developed a novel circular composites design method for products containing composite materials to support designers and improve product circularity. This method, which is the first of its kind to address the circular design of composite products, helps designers explore recovery pathways and generate design solutions. In this study, we evaluated the method’s effectiveness, accessibility, and usability in design practice. We tested the method with five design case studies in the construction, furniture, and automotive industries. The method was used to generate, evaluate, communicate, and detail product designs. We found that two of the five cases used the method to develop circular product concepts. In the other three cases, recycling rather than product-level recovery strategies was the result, with a focus on improving the material formulations instead of the overall product design. Although the designers considered the method accessible and usable, its effectiveness was restricted by the existing business, logistics, reprocessing technology, and policy contexts. These factors are intertwined and partly dictate the boundary conditions of the design, which means that to successfully implement the proposed method, the transition to a circular economy requires a holistic approach to adjust the design process, organisations, and value chains

Trust as governance tool in hybrid organizations: a case study for the dance Industry in the Netherlands

The organization of Electronic Dance Music (EDM) events requires much flexibility, due to the need to be able to quickly respond to new market trends. It induces high specificity in organizing these events. Our case study for the Netherlands, which is the world’s market leader in hosting these events, shows that hybrid forms of cooperation between producers facilitate this flexibility and adaptability. From the perspective of transaction cost economics this article focuses on the role of trust as governance tool of hybrid organizations. Trust between the collaborating event agencies has a reciprocal effect on perception of risk, therefore decreasing the need for comprehensive contractual governance or hierarchical control. We show that different types of trust can be sufficient as governance mechanism. The EDM event industry is a community-like creative sector in which calculative drivers such as repeated interaction and the importance of behavioural reputation add to trustworthiness between partners. In addition, social drivers such as a shared artistic vision lead to incentives to behave according to ex ante agreements in the design and creation of new, ground-breaking music sensations. From that perspective, we identify the factors that enhance the development of trustworthiness between partners in a hybrid organization

Circular Design of Composite Products: A Framework Based on Insights from Literature and Industry

Composite materials are an attractive material choice as they enable lightweight, low-maintenance products with a long lifespan. Recycling these materials, however, remains a challenge. Homogeneous material composition and the use of thermoset matrices complicate reprocessing, and result in low-grade recyclate. This means that closing the loop for these materials in a circular economy remains challenging, especially for glass fibre-reinforced thermoset composites. For a circular economy, products need to be designed to preserve product functionality, material properties, and economic value for as long as possible. However, recovery strategies, design aspects and their interconnectedness are currently largely unexplored for products containing fibre-reinforced polymers. The aim of this study was to identify circular strategies and determine design aspects for products containing composites. To achieve this, we conducted a systematic literature review and consulted experts. The circular strategies are largely similar to generic circular economy strategies as far as product integrity is concerned. However, on a material level, we identified additional approaches, the most notable of which is structural reuse, which preserves the material quality and thereby value. The design aspects were clustered and positioned along the product design process to support implementation. Finally, the strategies and design aspects we identified were brought together in a framework to support product design and design research for products containing composite materials in the context of a circular economy
