Build a mini biogas digester with 20 liter water bottle as digester tank it convert animal dung, food and kitchen waste into biogas by the action of anaerobic bacteria


Welcome to Pakistan science club, I am Sana mehmood and today I will explain how to make a bio gas plant. Hassan and Habab from Pakistan science club are also with us.

The things which we need to make bio gas plant are:

20l water bottle


PVC pipes

PVC caps

Gas valve, funnel and tyre tube

First of all cut PVC pipe equal to the bottle

We mark according to the length and then we will cut it

We have cut the PVC pipe according to the bottle's size.

Now insert the pipe into the bottle

To insert we mark here so that we can cut it easily

We have to make a hole here

As you can see that we have made the hole with soldering iron to fix the pipe

The pipe goes very straight into the bottle but we have to be careful that the pipe should be two inch above from the surface.

Now we fix outer pipe in it,

It should be completely opposite

We have entered both pipes into it

The best and easiest way to make it air tight is throw some soil in it and then apply super glue on it

Inlet and outlet pipe is connected to mini biogas Plant

Now we will connect a gas pipe in it which will connect with tube after connecting with t and that is the point where all gas gets collect

The other valve of it will be connected to our burner

Now we ask them how it will work and what materials are used.

We can produce bio gas with dung and many other waste materials

Firstly we store dung and then we seal it and leave it for some days

The bacteria will produce in one or two weeks and these bacteria will produce gas

Whatever gas produce will get store in tight tube

The construction of bio gas has completed

Now we will paint it with black color

The reason behind painting it black is that as you can see that the bottle is transparent and light will penetrate easily so Algae will grow

If the Algae grow then oxygen will be produced and when oxygen produced the bacteria will respire aerobically

That’s why we will paint black color and it also maintain digester temperature -----------------

As you can see that finally our bio gas digester---- has completed

Now we will put mixture of dung and water in it

Take equal amounts of water and dung

If the dung is ten kg water should be ten liter

Our project is finally completed now we will leave it for a week and then we will check the results.

Assalam-o-Alaikum Welcome back to Pakistan science club,

Last time we put dung (Gobar) in our mini biogas digester

The time has come to test

The bio-gas is produced not

Our gas tube full with gas

Now tyre tube seems filled with biogas

Our biogas plant experiment has been successful

Now we will put different waste material to test production of biogas
