The how-to handbook
Just follow the steps and you will end up with a mini biodigester that can light up a flame










Step 1
Bioreactor
Mix the manure with the water in the same proportion until everything is dissolved. Grab the 20 L water bottle and pass the tube through the lid, and glue it. Now, pour the manure mixture into the bottle and glue the lid, leaving a tiny piece of tube inside the bottle. Next, secure the rest of the tube to the bottle with tape so it doesn’t move and it’s at the right height.

Step 2
Sulfuric filter
Grab the glass jar and make two holes in the lid with the size of the male-male hose pipe connector using the drill with the crown drill bit attached. Make sure the connectors fit into the holes, and glue them with the silicone gun. In the inside of the lid, attach the female-female hose pipe connectors into the male ones and glue again to ensure it is secured. On the outside part of the lid, screw the female hose connectors into the male ones.

Step 3
Safety bottle
Grab the 1.5 L water bottle and cut off the top using the box cutter. Put that aside. This bottle will serve as a safety component, because it will be filled with water and one of the ends of the tubes will be submerged there. If the gas comes out with a lot of pressure, there will be bubbles, alerting that the camera is full, so it has to be changed in order to collect more biogas.

Step 4
Assembling
Place a metal clamp on the end of the tube and insert a flow control valve. Tighten the clamp with a screw so the connector doesn’t move. Do the same on the other side with a short piece of tube. Connect the free part to the connector of the glass jar that has a piece of tube attached to it in the inside and secure it with another metal clamp.

Step 5
Ready to flame
Insert the remaining piece of tube into the safety bottle previously cut and fill it with water to the top. The mini biodigester is ready to work!
