In circular concrete design, beside cement replacement with more environmentally friendly cement types, there is also an urgent need for sand replacement with fine recycled concrete aggregates (fRCA). The variations in physical and chemical properties of fRCA and lack of standards for their quality evaluation are the main reasons for not yet...

This paper discusses the state-of-the-art of the fine recycled concrete aggregates (fRCA), focusing on their physical and chemical properties, engineering properties and durability of concretes with fRCA. Based on the systematic review of the published literature, it is impossible to deduce without any further research the guidelines and tools...

To ensure a circular economy for plastics, insights in the environmental impacts of recycling and optimal recycling choices for specific plastic polymers are crucial. This was obtained by determining the environmental performance of 10 selected recycling technologies with varying TRL levels, using the chemical properties of the top 25 produced...

The use of recycled polymers in 3D printing technologies has recently become a promising research topic because of the global concerns on plastic waste pollution and an increase in awareness of sustainability and circularity. In order to unlock the potentials of 3D printing beyond prototyping purposes, continuous fiber-embedded fused filament...

Stimulated by the growing demand for more sustainable polymers, explorative experiments were performed to substitute oil-based components by “green” monomers derived from bio-based compounds to decrease the carbon footprint of the production of such thermosets. The potential of itaconimides synthesised from itaconic anhydride e.g. obtained by...

Urban mining from construction and demolition waste (CDW) is highly relevant for the circular economy ambitions of the European Union (EU). Given the large volumes involved, end-of-life (EoL) concrete is identified as one of the priority streams for CDW recycling in most EU countries, but it is currently largely downcycled or even landfilled....

The ability to track & trace materials is a key feature in the entire chain, and it ensures circularity principles. Examples from plastic recycling show the enormous added value that analytical technology can have for the circular economy. During polymer production and recycling processes, pigments can be added for different purposes; e.g. as...

Polymers are one of the most versatile materials because oftheir excellent cost to performance ratio and durability. Thesereasons have driven the extensive usage of polymers in manycommon applications, and often, their lifespan exceeds theneeds of the application. This generates streams of polymerwastes which retain a substantial amount of their...

Increasing the stream of recycled plastic necessitates an approach beyond the traditional recycling via melting and re-extrusion. Various chemical recycling processes have great potential to enhance recycling rates. In this Review, a summary of the various chemical recycling routes and assessment via life-cycle analysis is complemented by an...

The increasing volume of Construction and demolition waste (CDW) associated with economic growth is posing challenges to the sustainable management of the built environment. The largest fraction of all the CDW generated in the member states of the European Union (EU) is End-of-life (EOL) concrete. The most widely applied method for EOL concrete...

PV deployment growth is an unmatched success story in the energy sector over recent years. However, European PV manufacturers are facing a decline in production due to competition from third countries. The fragmentation of the value chain is believed to be one of the major factor for this decrease in the competitiveness. SUPER PV is a...

The shredding of waste of electrical and electronic equipment (WEEE) and other products, incorporated with nanomaterials, can lead to a substantial release of nanomaterials. Considering the uncertainty, complexity, and scarcity of experimental data on release, we present the development of a Bayesian belief network (BBN) model. This baseline...

Portland cement production is an energy-intensive process responsible for a significant share of the total CO2 production. Its replacement with low carbon binders from by-products of industrial processes is a sustainable alternative for innovative construction materials. In addition, the combination of low carbon binders with recycled aggregates...

In the small scale LNG infrastructure, composite materials are scarcely employed. Potentially, cost effective solutions for LNG applications could be developed thanks to the advantages of composite materials over metals such as weight savings, design flexibility and recyclability. The research presented in this paper focuses on the mechanical...

Reclaimed asphalt (RA) that contains polymer-modified bitumen (PMB) offers a potential premium material contribution for recycling. This study investigated the influence of soft virgin bitumens on the chemical and rheological properties of three reclaimed PMBs from different "old" surface-layer asphalt mixtures in Europe. Although the PMB...
