Gold Standard Local Stakeholder Consultation Report
Cleaning of the kitchen and pots used for cooking is easier as biogas is a clean burning
fuel and does not produce the levels of soot and other particulate matter that is produced
by burning fuel wood and kerosene; and
The slurry produced from the biogas units is a valuable organic fertiliser that can be
applied directly to the fields or composted with other organic material to improve crop
yields and reduce the use of chemical fertilisers.
Non Technical description of the biodigester
In each household, a family-size biodigester together with a biogas-based cooking stove unit will
be installed. The biogas units will be constructed of bricks, sand, cement, pipes, pipe fittings,
metal clips, wire and gas burners. Each bioreactor will be a mesophylic fixed dome. The capacity
of the biodigesters will be either 2m 3 or 6m 3 of biogas per day. The biogas unit size for a
particular household will be chosen based on the number and type of cattle owned by the
household and the number of people in the household. SKG Sangha will build the systems with
the help of people from the households. Cattle dung and wastewater will be fed into the
biodigester daily. Cattle dung and kitchen wastewater will be added to a mixing tank above
ground which has an inlet pipe to a digester chamber which is below ground. The dung and
wastewater slurry remains in the chamber for approximately 40 days and breaks down
anaerobically producing biogas. This biogas builds up above the slurry and remains in the
chamber until it is released through the gas outlet pipe at the top of the dome when the gas burner
in the household is turned on (the pipe at the top of the biodigester leads to the cooking stove in
the household). The biodigester also produces slurry which is pushed into the outlet tank and
displacement chamber as the biogas builds up in the digester and finally exits through the slurry
discharge hole. The technology has been tested and widely used in India.
CPA Eligibility
To include a CPA into PoA the following conditions should be fulfilled by the CPA;
1. CPA boundary should be in the PoA boundary
2. CPA should involve the installation of biodigesters at household level
3. The capacity of the biodigesters should be in the range of 2-6 cubic meters
4. Households that are using traditional cook stoves and the fire wood used should come
from a non renewable source and the animal waste management system is a partial
anaerobic fermentation
5. The Aggregated annual emission reductions of all systems included shall be less than or
equal to 60 kt CO2 equivalent and the Emissions reductions achieved through methane
avoidance are below 20 ktCO2e.
6. The CPA should not be a CDM project and not a part of another PoA
PoA activity is a Voluntary action:
There is a separate and same type of activity from the Government of India through its Ministry of
New and Renewable Energy. The outreach of the project is very limited and so far the number of
