The production of biofuels from an algae bioreactor is a hot topic, if you’re interested in biofuels, alternative energy and you’re a green DIYer.
As we have already mentioned in earlier articles on the topic, government officials in the U.S. are already funding various projects to encourage scientists and companies to implement this technology.
Here we would like to show you a way to do this too using recycled water bottles to make an algae bioreactor at home. The procedure is simple and very easy to follow, so why not take up the green challenge and have your part in cutting atmospheric greenhouse gas emissions?
These are the steps you need to follow:
1. Making a carbon dioxide delivery system
This is done by connecting an eight-port sprinkler system manifold to an one inch long PVC pipe. Make sure all threads are taped well using Teflon tape before the pieces are attached to each other. Then attach the PVC pipe to one end of the T-connector and block off the other end.
2. Fit the tubing
Cut out as many pieces of flexible tubing as you have ports on your manifold. If you decide to use less ports, then make sure only they are open and close the remaining. Then connect the tubes to each port on your manifold.
3. Fit the system
Using zip tiles, place the air system onto a metal rack, and attach it to a tank of carbon dioxide.
4. Attach the water bottles
The next step is to attach the water bottles to the same metal rack using hot glue.
5. Grow the algae
At this stage, you have to create the suitable medium for growing algae. A standard one that you can use is the garden store fertilizer that contains all nutrients needed for the algae to grow.
6. Measure the amount of algae
You can collect some pond algae from the nearest swamp, or simply buy from an online vendor. The crucial part here is to measure a fixed amount of algae, which should be added to the medium.
7. Growing algae
Allow several days for the algae to bloom and become denser, then use a regular French press to extract it from the solution. The biomass of the dried algae can be used as bio-fuel
