The circular economy plays an important role in the preparation and recycling of polymers. Research groups in different fields, such as materials science, pharmaceutical and engineering, have focused on building sustainable polymers to minimize the release of toxic products. Recent studies focused on the circular economy have suggested developing new polymeric materials based on renewable and sustainable sources, such as using biomass waste to obtain raw materials to prepare new functional bio-additives. This review presents some of the main characteristics of common polymer additives, such as antioxidants, antistatic agents and plasticizers, and recent research in developing bio-alternatives. Examples of these alternatives include the use of polysaccharides from agro-industrial waste streams that can be used as antioxidants, and chitosan which can be used as an antistatic agent.

Rapid advancement of flexible electronics has generated a demand for sustainable materials. Cellulose, a renewable biopolymer, exhibits exceptional mechanical strength, customizable properties, biodegradability, and biocompatibility. These attributes are largely due to its hierarchical nanostructures and modifiable surface chemistry.

The accumulation of nitrate (NO) from agricultural runoff poses a growing threat to ecosystems and public health. Converting nitrate into ammonia (NH) through the electrochemical nitrate reduction reaction (NORR) offers a promising strategy to mitigate environmental contamination while creating a sustainable circular route to fertilizer production. However, achieving high NH production and energy efficiency remains challenging.

To contribute to the circular and sustainable economy framework, waste tire rubber reclamation by extracting carbon black through pyrolysis and heat treatment and then ingeniously designing it as an electromagnetic wave absorbing (EWA) material is proposed herein. The results showed that the pyrolysis-recycled carbon black (RCB) was heterogeneous with multiple interfaces, making it suitable for EWA application. The RCB was processed at 500 °C-1000 °C to study the changes in the composite and microstructure as well as the EWA properties.

Shifting towards a circular economy in the built environment is considered an important step toward fostering environmentally sustainable and socially resilient cities. Housing cooperatives, established to provide affordable and democratically governed housing, may offer structural advantages for embedding circularity - but their role in circular transitions remains underexplored. This study investigates how cooperative governance may influence the implementation of circular strategies, including circular design, product-service systems, and shared resource models, across different housing types.

Vegetable side streams are resulting non-edible by-products from vegetable processing. These side streams are a rich source of bioactive compounds and macromolecules. Despite their potential for high-value applications, these materials are frequently used in low-value applications or discarded, contributing to resource depletion and environmental concerns.
