What The HEC | Tips on Organic Composting in your green bin

‘Organic materials’ which in a ‘waste-related’ context is anything that was recently alive/growing, contain important nutrients. To make best use of these, we are lucky to have some of the best commercial composters operating here in SA. They shred and hot compost the materials from our green-lidded organics bins, killing nasties whilst maintaining just the right temperature and moisture for bacteria to decompose materials. Within 10-12 weeks, rich compost is screened to remove contaminants and is then ready for use by our local farmers who grow our food.

Due to the heat and efficiency of composting in our commercial systems, residents of metro Adelaide Councils should be able to put food scraps /organic materials into the green organics bin (FOGO). This includes shells, (seafood and nuts), bones, shredded paper or paper-based material, tissues/paper towels, pet waste, and certified compostable food packaging/ bags. The exception to this rule is textiles as they get caught in machinery and don’t decompose within the composting timeframe.

One of our large commercial composters, Jeffries, still receive a lot of plastic in the green bin, so have built a machine called ROSS (Recycled Organics Sorting System), to screen material after it has been mulched and composted, to remove contaminants (e.g. plastics, glass, metal). It is important for bin users to ensure only the correct items are disposed of.

Jeffries have a great infographic explaining the difference between compostable and biodegradable here. We recommend sharing this information with friends and family as it can be tricky to navigate packaging. They also have a list of what can/can’t go into the green bin (for metro Councils) here.  

There are also great educational videos for their composting process available here: compost loop & ROSS.

Composting provides a positive outcome that grows our food, whereas if these materials end up in landfill, they don’t get the appropriate air and water required to break down and therefore it creates methane, a dangerous greenhouse gas. Let’s support locals, our economy and our planet by giving FOGO a go!
