Concrete mixes can contain up to 80% sand. But engineers in Australia have found a way to substitute used coffee grounds for a significant proportion of sand requirements, delivering a concrete that is not only more sustainable, but also 30% stronger than typical concrete. https://www.rmit.edu.au/news/all-news/2023/aug/coffee-concrete
T-top bollards are lightweight, versatile, highly visible and, thanks to their t-top, quite stable in windy environments. They are used to direct road or pedestrian traffic and to mark out unsafe work areas. The OC Eco T-Top Bollard is Australian-made and made from 100% recycled material (old bollards and locally sourced waste plastics)
The release of the Oppenheimer film, the story of the director of the Manhattan Project, has prompted many people to go online and search for an explanation of the difference between fission and fusion, two fundamental scientific concepts.
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei and releases energy.
Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.See https://www.ansto.gov.au/news/fission-vs-fusion-an-explainer
