Bioreactor
The Bioreactor Nav depicts a recycled tote.


Biomass
The organic material that breaks down in a digester is called biomass. The apparatus where biomass is broken down is called a digester or bioreactor.

Aerobic -vs- Anaerobic
There are two forms of digestion: aerobic and non-aerobic (or anaerobic). What's the difference? Oxygen from the air is the difference between aerobic and anaerobic. Aerobic digesters are open to the air. Anaerobic digesters are sealed, preventing oxygen from entering.

Aerobic Digestion
We recognize the ugly odor of aerobic sewage treatment as we drive by. This is because they are open to the air.

Anaerobic Digestion
Sealed containers that digest without oxygen do not pollute the air - they are sealed! The obvious benefit is to your nose. There are some other reasons why anaerobic digesters are so cool. There are very useful byproducts at the end of the bioreaction process.

Biogas
In an anaerobic process, the gaseous vapors that bubble off are methane. We call this fuel biogas. As it pushes out of the container, it can be collected and stored for later use. Burning biogas is very useful in many applications.

Effluent
The liquid on the top is called effluent. It makes awesome fertilizer. Drain it off - to water and feed your lawn and garden.

What's Left?
The solids remaining in the bottom are basically dirt. Mixing it with composted material makes excellent soil for gardening.

Bioreactor
Developing the mini and micro Bioreactor is the scope of this R&D project. This is a very hands on - learn as you go style of project. There is much information online concerning this area of research. There are many who have gone before. Organizing the knowledge and developing the equipment & technique for successful operation is very useful for sustainable living.
