Description of theproblem:

After carrying out an inventory of greenhouse gases in the department, itis concluded that the greatest contribution to total local emissions corresponds to Agriculture, forestry and otherland uses. In particular, livestockre presents 67.89 % of this sector and 36.59% of total emissions.

The department of General Alvear has a population of approximately 47,502 inhabitants and the annual emissions per capita are  8.42 t CO2e.

Consideringthis, it can be observed that there is an immediate need for treatment of emissions of gases that comes from animals, accompanied by the awareness of the population and the implementation of techniques for the use of small-scaleorganicwaste.

Overall objectives:

The main objective is the reduction of emission of greenhouse gases, product of livestock.

On the other hand, awareness at local level about the emissions of these gases and the implementation of ecologically and economically viable alternatives for the area, considering that the price of a gas cylinder is around $ 300.- and that a typical family uses two of them per the price of biodigester (which has a cost of approximately $ 40,000.-) and can be amortized in approximately 5 years, beingan option for the treatment of the organic waste generated by the families and by the animals that they have.
It also seeks to disseminate environmental education by teaching about waste management, renewable energy, reduce wastes enttoburial and environmental pollution caused by organic waste.

Resolution strategy:

The biodigestion teams will be strategically located, in order to ensure that the population has access to the observation of them, also providing training about the operation and be nefits generated by the production of biogas.

The rainfed area does not have a daily waste collection service, so the urban solid waste generated by residents is usually burned or buried, which is the main problem.

Families usually have some animals, such as chickens or goats, and the system proposed to implement with this project has the ability to digest up to 6 liters of organic waste and 15 liters of animal excrement, generating 3 hours of cooking on the stove.
