Does the Rubber Meet the Road?: Assessing the Potential of Devulcanization Technologies for the Innovation of Tire Rubber Recycling

Innovation is crucial to meet the circular economy goals for tire recycling. Devulcanization, an innovative recycling method of reprocessing tire rubber, offers a pathway towards achieving circular economy objectives. While previous research on devulcanization has primarily focused on technical aspects, this study shifts the focus towards...

Circular applications through selection strategies (CATSS): A methodology for identifying reuse applications for end-of-life wind turbine blades

Wind turbines are crucial for the energy transition, but their end-of-life treatment presents a challenge. Most wind turbine blades, made from composites, are currently sent for disposal or recycled through methods that degrade the value of the material. Structural reuse through blade segmentation was introduced as a recovery method that...

Circular Composites: Design strategies for products containing composite materials in a circular economy

In this dissertation, I investigate how to design products for a circular economy using composite materials. The circular economy is a potential solution to achieving a sustainable use of resources. Reuse of products and recycling materials lowers pressure on resource stocks, saves energy, and reduces the accumulation of waste. This requires a...

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...

Circular Design of Composite Products: A Preliminary 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. But closing the loop for these materials in a Circular Economy (CE) is challenging, especially for thermoset composites. In a CE, products should be designed for minimal impact while preserving their environmental and...

Structural reuse of high end composite products: A design case study on wind turbine blades

Composite materials, in particular fibre reinforced polymers, present a challenge when reaching their end of life. Current recycling processes are unable to capture the high-end material quality, thus challenging (re)use of composite materials in a Circular Economy. Structurally reusing segmented parts of end-of-life products as construction...

Structural reuse of wind turbine blades through segmentation

Composite materials offer many advantages during the use phase, but recovery at the end of a lifecycle remains a challenge. Structural reuse, where an end of life product is segmented into construction elements, may be a promising alternative. However, composites are often used in large, complex shaped products with optimised material...

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 chal-lenge. Homogeneous material composition and the use of thermoset matrices complicate repro-cessing, and result in low-grade recyclate. This means that closing the...

Offshore wind farm decommissioning: An orientation of possible economic activity in the south holland region and the rotterdam port area

A significant part of wind energy in the Netherlands is generated by offshore wind farms at sea. In the coming decades, the number of wind farms will be scaled up in line with current energy transition and sustainability objectives. What happens to these wind turbines when they reach the end of their operational life? What volumes of material...

Thermal simulation of a dinghy sailor

This paper describes the development of a model to simulate a dinghy sailors’ body temperature during a sailing match. This simulation has been developed as part of the master thesis by the author: “Thermal optimization of competitive sailing gear”. A literature study is done to define the human body heat balance and thermal comfort. Next a...

The history of the Dutch Coast in the last century

The aims of this paper are: 1. To publish some available coastal measurements and computations of more than local importance. 2. To investigate the influence of groynes in practice. 3. To investigate the motion of the gullies in the outer deltas. The following conclusions are drawn: 1. The gross littoral drift along the Dutch coast is of the...
