Baseline Situation
|
Most of the families in rural India use firewood, dried dung cake and/or kerosene as fuel for cooking and lighting. Women and children collect wood for some hours several days a week. This practice encourages deforestation. Collecting wood and cooking with it in the traditional cook-stove take considerable time. Women, who are in charge of these chores, do not perceive any income so they depend entirely on men for their needs.
Furthermore, the smoke coming from the traditional firewood stove and kerosene burning affects their wellbeing. Indoor air pollution is a major cause of health problems in women and children.
Most of the villages are unhygienic with unmanaged solid residues: kitchen and animal wastes.
Farmers are also confronting tough circumstances. Actually, several farmers in India have committed suicide due to repeated crop failure, inability to meet the rising cost of cultivation and indebtedness.
Because of the indiscriminate use of chemical fertilizers and pesticides the expenditure on agriculture has gone up and land fertility has come down resulting in lower crop yields.
Finally, the use of kerosene, wood and chemical fertilizers contributes to the global emissions of greenhouse gases. Moreover, wastewater and unmanaged solid waste also produce greenhouse gases.
This situation calls for urgent action!

Project Description
To change this situation SKG Sangha developed a system called ‘Composite Vermicompost Bioreactor’. It mainly consists of two main parts: a family size bioreactor and a vermicompost production unit.
This project aims to diffuse about 500 composite vermicompost bioreactors. SKG Sangha will conduct capacity building activities to speed up the diffusion process. Rural people will be trained on how to construct efficient units and employment will be created.
The untreated animal excrements, kitchen waste and wastewater will be managed properly when fed into the biodigester. The so-called biogas is produced in this biodigester as a result of bacteria activity that decomposes the organic matter in an anaerobic environment. This biogas is a clean fuel used for cooking and lighting.
Time spent on cooking and wood collecting will be diminished. This ‘extra’ time will be spent on sustainable income generating activities by assisting the vermicompost production. This process converts unmanaged organic wastes into nutrient rich manure creating sanitation and valuable organic manure.
Approximately 50% of the produced vermicompost will replace chemical fertilizers and pesticides on the beneficiaries’ lands, hence increasing soil fertility and saving money on chemical fertilizers. Remaining manure will be sold in the market providing women with regular income. They will be able to meet important family needs such as infant care and respective education.

Estimation of Emission Reductions
|
|
One average Composite Vermicompost Bioreactor has the potential to reduce over 10 tons of CO2 equivalent (tCO2eq)/year.
|
Action Carbone’s VERs
|
With the purpose of remaining conservative, minimizing risks and claiming only the amount of Emission Reductions needed to finance the whole project, Action Carbone proposed to SKG Sangha the option to employ a figure of approximately 6.5 tCO2eq/year/unit.
Five or six years will be chosen as the crediting period depending on the verification costs of a third party entity.
The quantity of reductions expected from this project are in the range of 17 200 VERs.
