Graphene development company SPARC TECHNOLOGIES has demonstrated that its graphene product in solution can adsorb gold and silver from mine tailings dumps.Adsorption, not to be confused with absorption, is a process in which molecules are held loosely on the surface of an adsorbent.The company, which has licenced graphene-based technologies from the University of Adelaide, has shown its product outperformed commercially available adsorbents, opening up a large potential market treating minesite dumps.

The Uber of Waste goes National

A 2023 start-up aiming to make recycling convenient and accessible to all is about to go national. The aim is to provide people with a home pick-up option for some of the "trickier" items the normal recycling bins can't handle - including soft plastics. https://wastemanagementreview.com.au/recyclesmart-goes-national/

Magnetic Attraction: Microplastics

A Kyushu University study (2021) estimated there were 24.4 trillion pieces of microplastics in the world's upper oceans or roughly 30 billion 500-ml plastic water bottles. Microplastics are tiny, toxic and very hard to remove from the environment. But researchers in the US have discovered that some Natural Deep Eutectic Solvents (NADES) can attract and bind microplastics, making it easier to remove them from the environment. And the N in NADES is key - natural - in this instance, think extracts from plants. https://www.research.uky.edu/news/researchers-develop-eco-friendly-magnet-battle-microplastics
