Most impressive is the range of Advantages that bio-gas plants provide beyond just the primary benefit of gas are following:

  1.   Excrement from animals and humans is turned from waste to benefit.
  2. The waste collected from one cow or buffalo provides enough gas for regular cooking needs.
  3.   Families with more animals and a larger plant could also use gas for electricity generation.
  4. The gas is a renewable, clean-burning source of fuel.
  5. Gas replaces wood or charcoal for cooking, eliminating the need to cut firewood and greatly reducing deforestation.
  6.   Families in unforested areas no longer have to pay for firewood or charcoal, saving them money.
  7. The post-digestion slurry is (nearly) free of pathogens and creates excellent natural fertilizer and mulch for crops, eliminating the need for families to buy chemical fertilizers, saving them money and retaining more nutrients in the land.
  8. Using gas instead of wood or charcoal eliminates respiratory health issues caused by inhaling smoke from open fires in kitchens and open spaces which affects women especially (who do most of the cooking)
  9. Toilets (or pit latrines) are needed to collect human waste, leading many families to have toilets for the first time. This is important for proper sanitation, which allows many families and children to avoid disease
  10.  Gas provides fuel for boiling water, sterilizing it and saving families and children from waterborne diseases (many people already know to boil water, but where fuel is scarce or expensive, free gas may lead to families feeling freer to boil water more consistently)
  11. If used for lighting, families can avoid using kerosene and its dangers–smoke inhalation and risk of fires and burns.

Biogas Plant Construction for Electricity Generation by PDBP

Biogas Plant Construction for Electricity Generation by PDBP

Pakistan Domestic biogas program (PDBP) announce that PDBP has started construction of 50 & 100 cubic meter biogas plants. These plants will have the capacity to run 5 to 10 kilowatt generators. These biogas plants are being installed for R&D to evolve future strategies.

Make your own Methane Biodigester

Make your own Methane Biodigester  

 Material Required:

1.       40, 50 gallon Plastic drum
2.       Plastic tube
3.       Shutoff valves
4.       Sealer
5.       4” dia PVC Pipe
 you will need one forty and one fifty gallon drum
a tightly seal able fifty gallon container plastic tubing shutoff valves and sealer 4 or 5 inch diameter PVC  pipe

Watch Video





 




Assembling of biodigester


Cut 2 holes into the seal-able drums lid one is the size of the PVC pipe and one the size of the plastic tubing place them at opposite ends of the lid cut out the bottom of the PVC pipe so the only have two remains


like this

Sealed the container and place the PVC pipe into at hole. This’ll be where you insert  the digester feed stock.
 Remove anything around rim of small fifty-gallon drum
This tank holds the gas
Capturing it between its roof in water
Cut two holes into the bottom of the forty gallon drums same as rubber tube
One whole will connect the seals great container
cut the tubing into 2 section 1 will connect the sealed container with the other drum.
And the 1 will let gas out.
Insert the shorter piece of tube in to the upside-down drum
3:59
Any other section of the other bottom so that goes down the full length of the drum
The other end of this tube connect to the sealed container
Attach the valve to gas release hose so the gas will escape. Then seal all connection
Each tube or pipe needs to be air tight.
Wait for these connections to dry. Fill the unused fifty-gallon drum water about two-thirds
Place the gas container upside down into the water and now digester has complete
Feedstock goes into the white pipe which produces methane gas (biogas) trapped in blue container
