Did you know that approximately 29% of the average Brisbane household bin is garden waste, meaning tonnes of garden waste is sent to landfill each year? You wouldn't be alone if you've assumed it's easy for organic matters to break down quickly in landfill because it's being buried back into the ground. But the truth is, it's difficult for materials, including organic matter like your garden waste, to break down in landfill. This is because waste is compacted and buried with very little oxygen, which means it breaks down slowly. This process (known as anaerobic decomposition) creates landfill gases made up of methane and carbon dioxide, which are potent greenhouse gases if they reach the atmosphere.
What does this mean for your garden waste?
Without boring you with too much more science, it means that your garden waste could be doing so much more to support a clean and green Brisbane, rather than languishing in landfill.
Top tips for good garden waste disposal
Here are the top three ways you can stop wasting your garden waste to landfill.
1. Get a green waste recycling service
Join more than 100,000 homes in Brisbane who already have a green waste recycling bin. Brisbane City Council has waived the $30 establishment fee, which makes it even more affordable. For a small quarterly fee added to your rates notice, this fortnightly collection service is probably the easiest way you can recycle your garden waste.
Tenants need to ask their property owner to approve and order the green waste recycling service for them. If you have an investment property with a yard, a green waste recycling bin can be an easy and affordable way to help tenants maintain the property.
Green waste collected by Council is transported, mulched and composted at green waste recycling facilities for beneficial reuse by suppliers. This means your green waste lives on through use in projects such as land rehabilitation projects.
2. Mulching or home composting
You can start by using your green waste on your garden beds as mulch. This is a quick and easy way to reuse your garden clippings. Mulch can help your garden retain moisture, reduce watering, and build soil structure.
Composting at home is growing in Brisbane with more and more residents starting their own composting systems. Garden waste can be used in your compost bin along with food scraps to break down into compost to help improve your soil quality.
3. Self-haul to a resource recovery centre
If you have access to a vehicle, you can take your garden waste to one of Council's four resource recovery centres.
As you enter a resource recovery centre, you will be asked what types of materials you have for recycling or disposal and the attendant will direct you to the correct area. Remember, that while fees apply to take your waste to a resource recovery centre, you can use your waste vouchers, or take advantage of free green waste recycling drop-off weekend events.
Did you know?
Council works hard to capture as much landfill gas (greenhouse gases) as possible through horizontal pipes and vertical wells. Landfill gas is monitored for quality, quantity and flow within the extraction system. Captured gas is converted to green energy and supplied back to the energy grid to power homes. Whiles this makes the best us of a bi-product of the landfill process, it is preferable to look at ways to recycle green waste to make sure the nutrients from our garden waste go on to benefit our gardens and local environment.
