A biodigester is a system where you gather manure, biosolids, food waste, other organic wastewater streams or a combination of these feedstocks occurs. Then, the wastes would start producing methane and carbon dioxide. People in Vietnam use this system to use it as natural gas.
We had to dig and create a big space to put some plastic bags that will contain animal’s manure.
It was not an easy process, but all of us worked hard and we finished it quicker then they expected!
We put two plastic bags into the one; therefore, no leaking was possible.
One of the student had to crawl through the plastic bag to even them out.
Then, we tied each end with pipes and rubber bands.
The home owner would spray water to collect pigs’ manures directly into the plastic bag. There is a hole that is connected to the bag.
This one is much bigger than the ones that we built, but this is the completed one. They would spray with black color or cover it up with black plastic bag to absorb as much heat as possible.
