Issues with airtight containers:
- Need to remove a lot of liquid and this 'fertilizer' is not always usefull (in the winter's months).
- Boost anaerobic bacteria & fermentation, brings smells...
- Not mycelium friendly.
- Loss of space because of the volume taken by water.
- Not able to process all organic waste.
- Average look.
- Very heavy (10 -12 kg, empty), may crack
-Not well ventilated : wood and terracotta can contain liquids = low or no air flow.
-Not so compact.
- prices 200 - 320 €
Often over technical stuff :
-Motors, heaters = electric consumption, failures prone.
- Need to add micro organisms, hazardous anaerobic process.
-Drying may be useful but spending energy is not necessary...
Our proposal:
- Natural materials (zero plastic)
- Maximum air flow
- Simple design and use, compost everything.
Zero plastic first test

hemp felt
beech wood
jute fibers mat 10mm
oak 18mm
cork board 15mm

Our key arguments :
- Decentralized composting is way simpler than concentrated composting.
- When biowaste is already distributed in small amount,
it is not necessary to gather it.
- Moving biowaste mostly means displacement of water.
We propose to reduce logistics to the minimum by just letting water evaporate on the spot...
Our key arguments :
- True passive ventilation =
with oxygen intake we can compost
with mycelium + worms + bacteria.
- 1 silo, 2 methods : worm composting or standard composting:
addition of carbon (wood chips), self-sustained heating phase.
Our key arguments :
- Scalable equipment:
55 cm silo 23 liters = 1-2 person household
75 cm silo 32 liters = 1-3 person household
- Versatile collection of looks :
European regulation : end of 2023.
