Subpod – A Subsurface Composting System Grows Vegetables from an Organic Waste!

The decomposition of organics in landfills produces methane gas, a greenhouse gas 24 times more damaging than carbon dioxide and according to the EPA, is 70 times more effective at trapping radiant heat than carbon dioxide. As a result, landfills have become the third largest source of human-caused greenhouse gases in the US. 

If we talk about across the globe, the health of our soil is degrading at an alarming rate, with an estimated half of the world’s topsoil lost in the last 150 years. Every year humans produce over two billion tonnes of rubbish and over 46% of this is organic waste that ends up in the landfill. 

In contrast, composting this material creates a valuable soil enhancer that replenishes depleted soils, protects against erosion, can replace synthetic fertilizers and helps retain water. Composting our organics protects air, water, and soil quality.

Composting with worms (vermicomposting) is an aerobic process, meaning the compost is exposed to air as it breaks down, avoiding climate unfriendly methane gas.

Now, there is a new way of composting at your backyard or gardens called ‘Subpod’, invented and founded by an Australian-born ecological artist and designer Andrew Hayim De Vries. His vision is to see every home, school, business or organization composting effectively across the globe.

He is a true nature caring person, has also founded the Compost Central, the first interactive compost education facility in Byron Bay along with lectured globally on the art of composting.

Along with Andrew, Saadi Allan – the Operations Director of Subpod, helps in building the organization by spreading the awareness about the composting. He is Head of Marketing with BeeInventive, the company that launched the Northern Rivers beehive invention that took the world by storm on crowdfunding platform Indigogo.

A patent-pending Subpod is a low maintenance (can be maintained by anyone in less than 10 minutes per week), efficient, and modular sub-surface composting system that harvesting the power of worms and microbes to build soil health and dispose of organic kitchen waste.


You can compost many organics things such as food scraps, including citrus, onions, fish, and even meat on the bone (in small quantities, after 4 months of use); paper and cardboard items; lawn and garden clippings; and a whole lot more. 

Subpod will allow you to compost any organic matter which would usually be discarded in a green bin, including lawn and garden waste, paper, and even natural fibers such as cotton clothing. 

How does Subpod work?

According to the creator of Subpod, you just need to follow some simple step – Install, Fill, Feed & Mix, and Spread!

Install this device into the soil of your veggie garden, with the top vents above ground and use the raised portion of the Subpod top as a seat. Fill the Subpod with healthy worms and castings, starter materials and food scraps, and leaving worms for 6 days to settle in.

Now, feed the device twice a week with food scraps and carbon matter (i.e. leaves, shredded newspaper, dry mulch) and mix the contents with the aerator tool. After a wait of 10 days of processing, it’s time take out some of the rich compost soil and spread it across your surrounding gardens.

The series of holes in the walls beneath the soil allow worms and microbes to move freely to and from the system and the surrounding garden bed, excreting rich nutrients which greatly boost the health and fertility of the soil.

The design of the Subpod creates a very moist, nutrient-rich 'feeding house' environment for worms and microbes, in which they eat and excrete. This process naturally keeps the compost inside from drying out, and also begins leaching moisture and nutrient outwards into the surrounding garden bed (as they move through the soil) - which boosts the fertility of your soil at the same time.

It is installed directly into the soil for high-volume processing of organic waste. Each module can process the organic waste from up to 12 people annually. Multi-module installations allow for high-volume on-site processing of organic waste without the on-going energy expenditure.


Separating organic waste becomes simple; smells, insects, and rodents are also eliminated. The device naturally regulates temperature and humidity. There are no moving parts and it does not consume electricity. 

The design of the Subpod allows worms and microbes to move freely between the module and the surrounding garden bed, aerating the soil and spreading rich nutrients as they move throughout. In little time, the soil is reconditioned and your plants benefit from richer soil 24 hours a day.

Subpod is designed to be embedded below ground, ideally in a raised vegetable garden to allow easy access for maintenance and harvesting of compost. Due to its position at your vegetables, you can compost and grow in the same place.

Some of the Subpod pilot projects have been successfully implemented at Talalla Retreat, Sri Lanka, and Santos Organics – Byron Bay, Australia. 

According to Josh, Cafe Manager at Santos Organics, they could able to produce over 100 liters of food waste every week!
