EVER WONDERED WHAT
HAPPENS TO YOUR GREEN
WASTE AFTER IT’S PICKED UP?
Scroll down to go on a journey from kerbside back to earth.
THE AVERAGE HOUSEHOLD GARBAGE BIN IN VICTORIA CONTAINS AROUND 50% ORGANIC MATTER – MOSTLY FOOD AND GREEN WASTE
Gases produced in landfill from green and food waste continue to be generated for decades
IF YOU HAVE A GREEN BIN, YOU CAN RECYCLE GRASS CLIPPINGS, LEAVES, WEEDS, PRUNINGS, TWIGS AND SMALL BRANCHES. CHECK WITH YOUR COUNCIL TO SEE IF THEY ACCEPT FOOD WASTE IN YOUR GREEN BIN.
EACH YEAR AROUND 400,000 TONNES OF GREEN WASTE IS COLLECTED ACROSS VICTORIA FROM KERBSIDE GREEN WASTE BINS ALONE.
GREEN WASTE COLLECTED FROM KERBSIDES IN YOUR NEIGHBOURHOOD IS SENT TO COMPOSTING FACILITIES.
BECAUSE NOT EVERYONE RECYCLES CORRECTLY, THE MATERIAL MUST BE DECONTAMINATED ONCE IT ARRIVES AT THE PROCESSING PLANT.
This costly task involves employees manually removing the non-organic waste, things like plastic bags and packaging, plant pots, glass, bricks and building materials.
A SCREENING PROCESS SEPARATES SMALLER AND LARGER PIECES OF FOOD AND GREEN WASTE.
Smaller pieces go straight to the composting process. The large pieces are shredded to reduce their size before composting.
THE PROCESS WORKS LIKE A COMPOST BIN AT HOME WHERE MICROORGANISMS BREAK IT DOWN.
When placed in landfill, food and green waste generates greenhouse gases including methane which is 25 times more potent than carbon dioxide. Food and green waste diverted from landfill can be turned into a useful product for improving soil, growing healthy gardens, and supporting food production.
IN-VESSEL COMPOSTING TAKES PLACE OVER 10-14 DAYS.
OPEN WINDROW COMPOSTING TAKES PLACE OVER SEVERAL WEEKS.
BOTH GENERATE TEMPERATURES UP TO 60°C.
This process kills any weeds, seeds, harmful bacteria and other pathogens, to meet Australian compost standards.
THE COMPOST IS MOVED AND IS SCREENED FOR THE FINAL TIME.
TWO GRADES OF COMPOST ARE PRODUCED, ONE COARSER AND ONE FINER.
Some of the product can be stored on site for maturation.
MOST OF THE COMPOST IS DIRECTLY LOADED INTO LARGE TRUCKS AND TRANSPORTED FOR USE IN AGRICULTURE.
It enriches the soil and helps to grow healthy foods for Victoria’s community.
