Giving coffee waste a greener future

Collaborating to divert 50kg of coffee waste from landfill each week
September 28, 2020

We have teamed up with our neighbours, Red Square Café and Westland Nurseries, in a bid to tackle the effects of coffee waste in landfill.

According to a study by Planet Ark, Australians consume around 6 billion cups of coffee each year with 93 per cent of waste from coffee grounds ending up in landfill.

Every day we are collecting the spent coffee grounds from Red Square Café and taking them to Westland Nurseries where it is incorporated into a compostable product over a period of six to eight weeks. We then bring it back to Hobart Airport to be used on our gardens and landscaping projects.

When added to landfill, coffee grounds produce methane which has a warming potential far greater than carbon dioxide.

By working with our neighbours, we not only have the opportunity to reduce the volume of harmful gasses produced, we are also able to give the coffee grounds a second life.

Circular economies aim to move away from the make, use, dispose model in favour of reusing or recycling a product to extract the maximum value.

This is the first of what we hope will be a number of circular economy projects at Hobart Airport.

While it is an experiment to begin with, we are hoping this inspires others to move away from the linear waste model and look at ways in which they too can embed circular economy principles in their operations.

The project is an extension of Hobart Airport’s Waste Strategy which has seen purpose-built bins that segregate landfill, recycling and compostable waste introduced throughout the terminal, resulting in a 30% reduction in waste to landfill in the first year alone.

Camera traps are also used to monitor the movements and better understand the behaviour of animals in the airport environment.  

Since the installation of camera traps in early 2016, images collected have shown that many threatened species use the environment around and within the airport boundary including the Tasmanian Devil, the Spotted quoll and the Tasmanian bettong.

We recognise our role in protecting the biodiversity of the airport and Tasmania more broadly and are confident this technology will assist us in doing so.

Initial testing of virtual fencing devices in Tasmania has seen a 50 per cent reduction in road kill deaths over a three-year period and has been instrumental in protecting the remaining Tasmanian Devil population.

The virtual fencing will be monitored by Hobart Airport’s environment team to capture and report data on the rates of roadkill deaths in the area and better understand the behaviour of the animals that call the airport home.
