Research by UNSW academics shows that special treatment of liquid resin used in 3D printing can cause the material to mend itself if it becomes damaged.
Ten years of citizen science data has informed a UNSW study which found plastic dominates the rubbish found on Australian beaches.
UNSW Sydney researchers have successfully merged 3D/4D printing with a chemical process to produce “living” resin, which has huge potential for fields as diverse as recycling and biomedicine.
Single-use plastic bags will soon be gone from major supermarkets and many other shops too. Campaigns to reduce plastic even more should focus on positive advice, rather than shaming shoppers.
The real and direct impact of ocean-going plastic is not where it ends up, but the route it takes from our beaches to the great ocean garbage patches, writes Erik Van Sebille.
The giant garbage patches in our oceans will continue to grow for hundreds of years even if no more is added - and our garbage has made its way into every ocean in the world, according to startling new research.
Commercial production of the world's first "green" steel is underway at the Sydney furnaces of Onesteel, following a global licensing agreement between the Australian steelmaker and UNSW.
