Melbourne researchers turning wine industry trash into treasure

Melbourne researchers are working to turn trash into treasure in the wine industry. Around 2 million tonnes of grapes are crushed each year and more than half end up as grape marc – the skins, pulp, seeds and stems remaining after the fruit has been pressed. Swinburne University professor Enzo Palombo is working to create technology that will help wineries take advantage of the chemicals found in the waste.
