The document describes a school project to produce biogas through anaerobic digestion of organic waste. Students designed and built a simple biodigester system using a water bath to heat the digester. They filled the digester 3/4 full with a mixture of 40% organic waste and water. Analysis of the gas produced through gas chromatography confirmed the presence of methane, indicating biogas had been successfully generated. The students were pleased with producing biogas and learning about an educational system for generating renewable energy from organic materials.

1. PRODUCTION OF BIOGAS
AT SCHOOL

2. BIOGAS PRODUCED FROM
THE ANAEROBIC
DIGESTION
(A BIOLOGICAL PROCESS THAT
DEGRADES ORGANIC MATTER)

3. FOR HEATING THE
DIGESTER, HAS
CHOSEN THE
SIMPLEST SOLUTION
THAT IS IN A WATER
BATH, WITH A
SMALLER CONTAINER
INSIDE THE LARGER
ONE, CONTAINING
HEATED WATER

4. EDUCATIONAL SYSTEM FOR
PRODUCING BIOGAS

5. THE NEXT STEP WAS THAT OF
REMEDYING THE MATERIAL. FROM
THE LABORATORIES OF TANNERY, WE
RECOVERED A STEM PVC, TO USE AS
A CONTAINER, THE WATER HEATER 10
LITERS USED FOR THE HEATING AND
THE CIRCULATION PUMP WERE
ALREADY IN THE LABORATORY,
COMPOST

6. SYSTEM DESIGN

7. SYSTEM DESIGN

8. After mounting all we had to
think of the organic material
to be placed in the
biodigester.
We used the organic material
contained in the compost and
the digester was filled to
about 3/4 of a mixture of 40%
of organic waste and water.
The choice compost seemed
interesting for the presence of
bacteria that degrade
naturally cellulose

9. OUR GARDEN FOR THE
PRODUCTION OF COMPOST
ISATISFIED
FARMERS

10. WE COULD NOTE WITH SATISFACTION THE
CONTINUING EDUCATION OF BUBBLES IN A POT
OF WATER TREATMENT, RAISING THE STORAGE
VESSEL AND FINALLY TURNING ON A SMALL
BURNER FITTED IN THE PIPE END.

11. IN THE LAB

12. THERE
WILL BE
THE
BIOGAS?
?
CHEMICAL ANALYSIS BY GAS CHROMATOGRAPHY

13. CHEMICAL ANALYSIS BY GAS
CHROMATOGRAPH COLA
TECHNICAL AREA IN THE HEAD
METHANE
THERE IS
BIOGAS

14. EVIDENCE OF THE FORMATION OF THE
FLAME

15. DESIGN TECHNOLOGY SYSTEM

16. THE END OF ACTIVITY
YES
THE BIOGAS
IS PRODUCES
I’m
HAPPY
