The waste from our plates matters. In 2017, Project Drawdown ranked 100 of the most promising climate change solutions, and reducing food waste came in third place – beating both solar farms and electric cars. We can make a huge difference for the environment, just by getting creative with our waste!

The average couple tosses roughly 300kg of food waste in the bin every year. All that food has the potential to become beautiful, rich organic fertiliser – capable of helping plants grow, re-building our soils and help reversing the effects of climate change. But a lot of people have a negative view of composting. Traditional compost is known to be smelly, a bit of an eye-sore and even attract rodents to your home. On top of that, over half of the world's population lives in densely populated areas, so having a traditional compost pile in their yard just isn't an option. But what if things were different?

There is no planet-B
If our food waste was a country, it would be the third biggest producer of greenhouse gases (behind China and the US), contributing 8% of the overall emissions that are causing climate change.

But if just 1% of the people living in cities around the world started composting – it would have the same environmental impact as planting a 3.5 million acre forest! Why wait for our leaders to make the changes needed for a greener future? We can take action into our own hands by starting to compost today.

Turn your food waste into a planet-saving super solution
Compost has restorative super powers! It’s a natural fertiliser that can revive barren dirt back into fertile soil, teeming with the microorganisms and nutrients that plants need to grow. When we compost our food waste, we shrink its CO2 impact back down to the ground and put carbon back in the soil where it belongs. It’s up to us to reverse the impacts of climate change and breathe life back into the soil.

“Kiss the Ground” in your backyard
There’s never been a better time to fall in love with soil! In 2020, an epic documentary called “Kiss the Ground” shined a spotlight on the soil health crisis. Narrated by Woody Harrelson, it shows how regenerating the world’s soils could rapidly stabilise Earth’s climate, restore lost ecosystems and create abundant food supplies. It’s going to take time for us to end food waste and restore the world's soils, but our backyards, courtyards and patios are the perfect place to start.


What are the dimensions/specification and capacity of the Subpod?

SUBPOD: The external dimensions are: 29.5 in (750 mm) Length x 17.7 in (450 mm) Width x 16.9 in (430 mm) Height, including the lid. The internal dimensions are: 28 in (710 mm) Length x 16.1 in (410 mm) Width x 11.5 in (290 mm) Height below the soil level. A total internal volume of 30 gallons, (115 litres), which gives a total composting volume of 22 gallons (84 litres) due to the soil level and air flow area at the top.

SUBPOD MINI: Dimensions: 49.4cm L x 45cm W x 43cm H

What can I compost in Subpod?

You can compost a much bigger variety of materials in Subpod than in other worm farm systems! See the full list below:

1. Foodwaste -  Most food waste can be composted in Subpod without worry. Fruit and vegetable scraps, eggshells (crush them first), coffee grounds, used tea leaves, spoiled plant-based milks, grains, pastas, breads, nuts (and their shells), seeds, pits, husks and so on. Small amounts of meat, seafood, dairy foods, citrus, onion and garlic may also be added. Subpod can also process spicy herbs, peppers and oils but it’s best to introduce these slowly in small amounts at first, and only once your worms are fully established (after around three months).

2. Paper & Card - Most scrap paper and cardboard can be added to Subpod, as long as it’s not laminated or super glossy. Again, the smaller the pieces, the better. Junk mail, office paper, bills, envelopes (no plastic windows), post-it notes. Paper plates, tissues, egg cartons, paper cupcake liners, baking paper, even card and paper packaging is fine.

3. Natural Fibres - Cotton wool balls and pads, tampons, toilet paper cores and even natural latex condoms and gloves can go into Subpod. Old clothing, face washers, napkins, tablecloths and very old towels can be used as long as they are made from natural fibres like cotton, tencel, linen, hemp or wool (no polyester, nylon, acrylic or blends) – just shred them into small pieces first. Washer and dryer lint is okay too, as long as it comes only from clothing made from natural fibres.

4. Wood & Bamboo - Sawdust (no paint) is great. Toothpicks, disposable wood, bamboo and bioplastic cutlery and crockery can be composted, along with dead matches, bamboo skewers, garden prunings (cut 'em up small), and charcoal from the fireplace – as long as you wash off the ash which is too alkaline for Subpod.

5. Human and animal waste  - Human hair and nail trimmings, used facial tissue, used cotton bandages and sanitary items can all be composted in Subpod, as long as they are made from 100% natural fibres. Pet hair of all kinds is fine, along with soiled newspaper and hay cage liners and faeces from vegetarian pets and livestock (rabbits, guinea pigs, hamsters, cows and horses). Dog and cat faeces are NOT suitable for Subpod if you’re eating the plants growing around it. But fine if you want to have a separate one for this purpose.

What can’t go in the SubPod?

You cannot compost non-organics such as plastic, tin cans, cigarettes, building waste, toxic waste, glass, or any other similar materials in Subpod.

How does Subpod differ from other worm composting systems?

It allows you to compost directly in your garden allowing the worms and microbes
to distribute nutrients into the soil.

Because you’re composting in the soil, your system is insulated → which means
you can compost in a variety of climates

Subpod sits 90% below ground, which deters pests and predators

The worms are able to move freely between the Subpod module and the
surrounding garden which creates a worm friendly environment.

The Subpod has a unique modular design, which allows multiple systems to be
installed in one bed and cater to larger volumes of waste.

Does Subpod need to be underground?

Yes - 12" (30cm) underground! Being underground is what makes Subpod different from other compost systems. The soil provides insulation and a way for worms and microbes to explore your garden and feed your plants. Above ground compost systems struggle to keep worms and microbes comfortable, and even alive, in summer and winter – but underground they're safe and happy (which is the secret to good compost).

How much soil is needed to fill the Grow Garden Bed with the Subpod Mini inside?

For the Subpod Mini in a Grow Bed you need 12.8 cubic feet or 363 litres of soil. This is about 7 bags of the 2 cubic foot size bags or in metric, is 8 x 50 litre bags.

Is the Subpod made from Plastic?

It’s great to be concerned about the use of plastic, and Subpod have put a lot of energy into this. When designing the Subpod they have considered many factors, and one of the main things that are important to them is a circular life economy.

They have found that the best material they can use now to manufacture the Subpod Mini's is polypropylene which is naturally BPA free. This is one of the safest plastics available from a health perspective with no endocrine disruptor chemicals and with undetectable leaching. Because they have designed the Subpod Mini for durability and long life use, as a priority they are initially making Subpods from virgin polypropylene and will field test blends of up to 50% recycled polypropylene to verify these blends have sufficient strength and longevity to permit the use of a percentage of recycled polypropylene in Subpod manufacturing.

Polypropylene is water and food safe and has been used in the food industry for many years, able to withstand high temperatures of about 110 degrees Celsius/230 Fahrenheit. Using polypropylene, Subpod Mini's are expected to have a minimum usable lifespan of 10-15 years in the soil without any leaching or degradation which is important since the Subpod Mini will contain and be surrounded by a microbe-dense soil in a wide range of conditions, including damp and high humidity areas.

Doubling as bench seating requires that the materials chosen support body weight. Polypropylene based Subpod Mini's can bear up to 200 kilograms/440.93 pounds.

Finally, the Subpod can be recycled when it reaches the end of its life in your garden, completing its life cycle. There are exciting plastic substitutes being developed which they are looking into, but most of these are designed to be composted after use and they need the Subpod to hold up strong for many years while it is efficiently composting all of your kitchen waste ;-)

It’s number for recycling is 5.
