There is no doubt that Australians love coffee. We consume 6 billion cups each year!
The ABC's War on Waste brought the issue of disposable coffee cups to the attention of the public, but have you ever thought about the leftover coffee grounds and what happens to them?
In 2016, with the support of the City of Sydney, Planet Ark released a feasibility study into the collection and recycling of spent coffee grounds (SCG). This report showed that 93% are sent to landfill with only 7% repurposed or recycled.
Spent coffee grounds are an important resource, rich in nutrients and minerals which are currently being wasted in landfill. Many different uses for SCG are being explored around the world, from odour busting clothing to biodiesel. It's important to repurpose SCG to make use of this fantastic resource and avoid the methane produced when sent to landfill. Methane is a powerful greenhouse gas, over 20 times more potent than carbon dioxide, and is created when organic materials break down without the presence of oxygen in landfill.
Thanks to the support of our Founding Members, Allpress Espresso, Genovese, Grinders, Lavazza and TATA Global Beverages via their Map Coffee brand, Planet Ark was able to trial a coffee ground collection and repurposing trial in Sydney.
Over this trial we;
- Repurposed over 13 tonnes of spent coffee grounds. This is equivalent to repurposing the grounds from over 550,000 coffees.
- Saved over 8.5 tonnes for carbon dioxide equivalent from entering the atmosphere.
We are now working with the industry to fund research and development to find a high-value end use for coffee grounds. This development will allow us to develop a sustainable collection system with the important goal of keeping coffee grounds from landfill.
