Reviewed by Bethan DaviesResearchers have found that recycled concrete powder (RCP) can replace up to 50 % of Portland cement in 3D-printed mixes—reducing carbon emissions by over half while maintaining printability. The study evaluated two types of RCPs in cementitious pastes using rotational rheometry, isothermal calorimetry, and life cycle assessment (LCA), along with printability tests to assess extrudability and buildability.

A new study has revealed that recycled paper food packaging may leach toxic metals into food, especially under acidic conditions, posing potential health risks previously underestimated. Recycled paper and cardboard are increasingly used in food packaging as part of global sustainability efforts. However, these materials may pose hidden risks in the form of toxic metals, often introduced through inks, adhesives, or processing agents.

QUT researchers have identified a new material that could serve as a flexible semiconductor in wearable devices by using a technique that manipulates the spaces between atoms in crystals. In a study published in the journal Nature Communications, the team applied “vacancy engineering” to enhance the performance of an AgCu(Te, Se, S) semiconductor—an alloy composed of silver, copper, tellurium, selenium, and sulfur—enabling it to convert body heat into electricity more effectively.
