Frequently Asked Questions

What happens to ground coffee in landfill?

Organic waste is the single most harmful waste stream to end in landfill - it does not just end back up in the soil like many people believe. Landfills are a big hole in the ground covered in layers of plastic to catch all toxic liquids produced by the waste. Organic waste needs oxygen to decompose naturally and since the organic waste has no access to oxygen, it creates greenhouse gases. In normal compost piles you turn the pile adding oxygen thereby avoiding the production of greenhouse gases. Other waste streams like plastics and metal just stay in landfill forever.


What is ground coffee good for?

Spent ground coffee is a fine-grained organic matter which is rich in a range of important nutrients. These nutrients including nitrogen, potassium, iron, calcium, and zinc are particularly beneficial for the fertility of soils. Therefore, the use of this resource in gardening can have beneficial effects for soil health and plant growth. The texture of ground coffee can also act to store soil water and reduce temperature variation around plant roots. Furthermore, ground coffee is slightly acidic with a pH of around 6.2 which sits in the ideal range for most plants.


What uses do ground coffee have in my garden?

Ground coffee has three main uses in your garden - composting, soil amendment, and worm farming. Within your compost pile, ground coffee will provide additional organic matter to be decomposed and converted into a nutrient-rich fertiliser to improve plant growth. Ground coffee added directly to your soil will act as a mulch to control soil temperature and moisture content, and also control weeds, pests, and improve plant growth in some species. In worm farming, ground coffee provides organic matter for worms to decompose which results in the creation of ‘worm castings’, one of the richest natural fertilizers available.


Can I put ground coffee straight onto my garden?

Sprinkling ground coffee on top of the soil is a great way to add a little boost of nutrients while also helping to deter slugs. However, we don’t recommend that you completely saturate the soil with ground coffee as too much will create a barrier from letting water pass through.

How does it work if I want to receive ground coffee?

Helping us divert ground coffee out of landfill is an admirable task and is amazing for our planet. The Reground service works so that you can receive a full van load of coffee all free of charge or collect smaller amount at our site in Alphington. For deliveries - we deliver straight to your door. We will arrange a time for drop off, preferably you are there to help our driver unload and clean our bins - but that is it. Easy and simple.

I run a cafe - how can I start diverting my coffee?

You’ve started considering your waste as a resource, great - you are already halfway to having implemented a sustainable waste practice. Get in touch with us - we need to see your space before getting you on, so a real life catch up is needed.


Will I save money?

You shouldn’t do anything for money, it’s not happiness - but yes, most likely. Sustainability is about being resourceful and innovating on processes, and we help all our cafes to maintain or to reduce prices. No guarantees though.


How much harm am I actually doing by throwing my ground coffee in the general waste bin?

Organic waste is the single most harmful waste stream to end in landfill - and it’s unnecessary as it’s a beautiful resource in our gardens. If you go through 20kgs of beans each week you produce 40kgs of used ground coffee weekly. That’s a total of 2 tonnes of ground coffee you send into landfill each year, emitting nearly 4 tonnes of greenhouse gases into our atmosphere. That is the equivalent to nearly 58,000 lattes!


Is Reground just a ‘waste removal service’?

No, Reground is much more than that. We call ourselves a waste education service. Our partner cafes are all helping us make Australia greener and we use their support to educate individuals in our community and the government on what direction we want our future to have. We collaborate with many like-minded cafes to support this agenda and everyone plays a great role in facilitating change. Also - your coffee ends back in the community making us a social enterprise.


What does the service cost?

Reground is a subscription service based on volume, get in touch to see where you fit in.


I only run a small operation, can I still be a part of Reground?

Yes, no amount of coffee should end in landfill.


I work for an office - could we join?

Absolutely - we have offices participating already and we are happy to help your office go green, too!
