An underground mini-compost that turns organic matter into natural fertiliser. The mini composter should be dug into the ground, making it perfect for small gardens where there is no room for a classic composter.
The Combi soil underground composter consists of three parts. First, fill the composter with soil and top it up with household waste.
Depending on the weather, bugs and microorganisms ensure the decomposition of the leftovers. This process creates optimal conditions for growth, heat is generated and the soil is loosened – a natural fertilizer is created.
Thanks to this method, we will get rid of the leftovers from the house and at the same time create our own natural compost, e.g. for flower and vegetable beds.

What is an Underground Compost Bin
Underground compost bins are designed to be partially buried in your garden soil. They are generally small to medium-sized and are particularly well adapted to composting kitchen waste.
This unique composting method differs from traditional “above ground” compost bins that just sit around on top of the soil. And by submerging the container, this system creates a more favorable composting environment than conventional bin types.
Keep in mind that because you have to dig a hole, this somewhat limits the size of these units. Burying a huge bin would be far too much work. Also, deep containers make it challenging to harvest the compost when finished.
You’re better off having more than one underground bin than one huge one.
How do in-ground compost bins work?
Unlike standard bins, these containers have holes in the bottom and sides, up to the height they will be buried. The holes allow for drainage and give free passage to worms and other beneficial insects. In addition, the surrounding earth acts as insulation, retaining the heat generated by decomposing waste. And the subterranean bin also holds moisture.
All of these factors set up a habitat where composting microbes can thrive! And decomposition is generally faster than in a traditional bin.
The in Ground compost bin
This is a classic semi-buried composter. These are intended to be stand-alone systems that you feed with all kinds of organic waste, but mostly kitchen scraps.
The maturing compost attracts earthworms from the surrounding soil, but you do not need to add extra worms.
