Coffee 4 Planet Ark
We love our coffee but we don't love the amount of greenhouse gases our beans emit when they're left to decompose in landfill.

There is no doubt that Australians love coffee. We consume 6 billion cups each year! 

But what happens to the coffee grounds left over after we’ve enjoyed our coffee hit? 

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. This report showed that 93% are sent to landfill with only 7% being repurposed or recycled.  

Coffee is an amazing resource with many different uses being explored across the world, from odour busting clothing to biodiesel. Repurposing coffee grounds is so important to not only make use of this fantastic resource but to avoid the methane produced when coffee grounds are sent to landfill. Methane is a powerful greenhouse gas, over 20 times more potent than carbon dioxide, which is created when organic materials break down without the presence of oxygen in landfill.  

We are excited to be trialing a new program at the end of 2018 - Coffee 4 Planet Ark, where we will be collecting spent coffee grounds (SCGs) from Sydney cafes, diverting them from landfill, recycling them into compost and soil fertiliser and researching other potential higher value end uses.  

This trial has been made possible thanks to the support from our foundation members Allpress Espresso, Genovese Coffee, Grinders Coffee, Lavazza and TATA Global Beverages. These companies are leading the way in innovation and responsibility of their end of life product. Thanks to their wonderful support we will be able to determine the best and most cost effective way to repurpose coffee grounds and develop a national rollout model to help keep the coffee grounds out of landfill.
