If it 'once lived' it can be recycled via the green organics bin.
Organics bins are located in staff kitchens, Hub Central, the North Terrace campus student kitchen and in the Ingkarni Wardli Atrium.
Most people tend not to think of food scraps as having an adverse impact on the environment because it is biodegradable. But unless regularly turned over, food breaks down very slowly in landfills due to a lack of oxygen. This creates methane, a greenhouse gas that is 20 times more potent than carbon dioxide. Around 90% of greenhouse gas emissions from landfills are a result of decomposing organic material which could be diverted*. Composting garden materials and food scraps diverts this organic matter from landfill and returns essential nutrients to the soil.
Along with food scraps, many other items can go in the bin, including coffee grinds, dead flowers, paper towel and tissues (which is why you often find a green bin in the bathroom) and 'bio' plates, cups and cutlery.
The Social Problem of Food Waste
Australian's waste around $10 billion worth of food annually - or 1 in 5 shopping bags of food - while thousands of people go hungry. OzHarvest is doing their best to change this. Since 2011, excess food from university eateries has been 'rescued' by OzHarvest volunteers who redistribute it to the homeless and disadvantaged members of the community.
As of March 2018, the University and National Wine Centre have donated the equivalent of 60,159 meals to OzHarvest that would otherwise have ended up in landfill. Diverting this food has helped the environment by saving 32,084 kg CO2-eq greenhouse gases and 2,867,579 litres of water.
