Prototype of Photobioreactor (BioR)

Methanogenic bacteria lives inside an Anaerobic Digester (AnDi) and digests organic waste that is introduced into it. As the bacteria digests waste they release a mix of biogas that contains methane, carbon dioxide, and hydrogen sulfide. This biogas is combustable and can be used as a source of energy, but we want to 'sweeten' the gas and increase it's quality for domestic and commercial use. AnDi is connected to Photobioreactors so this 'sour' biogas can be 'sweetened'.

 
 
 
 
 

This is a prototype of our photobioreactor (BioR) that contains our mix of photosynthetic cyanobacteria (algae). When unfiltered biogas is introduced to BioR the algae are able to 'sweeten' the gas by sequestering carbon dioxide, releasing oxygen, metabolizing hydrogen sulfide and increasing methane content. 

We plan on compressing the methane that comes out of the bags so that it can be stored and used on-site.

HOW IT WORKS

HOW IT WORKS

STEP 1: WASTE HANDLING

AnDi

Anaerobic Digestion is the break down of organic matter through the use of microbial communitites. These ubiquitous microbes also live in the digestive tracts of humans and animals. This process breaks down carbon-rich organic materials into biogas. Waste heat from building exhaust combined with heat harvested from solar heat exchangers is exchanged to keep microbes happy and healthy. 

FOOD WASTE

Food Waste from kitchens, resteraunts and super markets is rich organic matter with a huge potential to be converted into energy with utility.

BIOGAS

Biogas is methane, an extremely efficient fuel source which has a much lower carbon dioxide emission rate compared to other typical fossil fuels. Anaerobic digesters create methane as well as CO2 and trace amounts of undesirable hydrogen sulfide which can be filtered biologically.


STEP 2: PURIFICATION

BIOREACTOR

Algae are microscopic prokaryotes that use sunlight, H20, C02 and nutrients to produce oxygen while also breaking down hydrogen sulfide and other compounds into environmental friendly end products. Biogas is filtered through algae photo-bioreactors to filter out the impurities from the biogas leaving a purer consumer friendly grade of natural gas.

EFFLUENT

Effluent is a residual liquid from the anaerobic digestion process. Once all the organic matter is digested, effluent can be used as a rich fertilizer ideal for the backyard, farms and greenhouses.

SLUDGE

Treated Sludge comprises the solid “undigestable” fraction of waste, usually only 20-35% of the total volume of the original waste feedstock remains as sludge. Once removed from the anaerobic digester this treated sludge can be easily composted (as most of the compost work has already been accelerated by anaerobic bacteria). Treated sludge can either be used as compost in gardens or simply flushed into existing sewers.


STEP 3: STORAGE AND USE

BIOGAS

After biological filtration by photosynthetic algae, can be compressed and stored for future or immediate use. It can be connected to indoor and outdoor stoves, furnaces for thermal conditioning of buildings and used in natural gas generators and engines.


  1. The process starts within the anaerobic digester, where a special mix of methanogenic bacteria breaks down organic waste. This digestion process is continually releasing methane, carbon dioxide, and hydrogen sulphide as unfiltered biogas.

  2. A byproduct of anaerobic digestion is a rich organic fertilizer that can be used on-site

  3. The unfiltered biogas mix from anaerobic digestion is pumped through photobioreactors full of algae that use photosynthesis to metabolize hydrogen sulphide and sequester carbon dioxide while simultaneously releasing oxygen.

  4. We are left with pure methane (natural gas) that is compressed and stored for future use.
