In this work, it is intended to address the problem of Urban Solid Waste (USW) progressive generation and the decreasing spaces availability for its deposition. Based on this situation, main objective is to analyze the technical, economic and financial viability of an USW-organic-fraction-treatment home automatic and continuous system implementation, applied in Buenos Aires City, Argentina. In terms of the selected methodology, the following technical aspects are firstly studied:

- Domiciliary system (composter) analysis in its two possibilities of final result: i) deposition through sewage net, considered forapartments, ii) compost for amendment purpose, considered forhouses.

- System implementation viability within Buenos Aires from studies and field measurements.

Based on the technical analysis, economic and financial study hasthe objective of proving the significant saving for the city government that the reduction of organic waste fraction can potentially generate. In order to obtain these results, some of the considered economic aspects are:

- Definition of the budget able to be saved.

- Costs and utility generation since the domiciliary system implementation.

- Choice of a Rate of Return to calculate the Net Present Value of the project.

Regarding the conclusions, the main one is the verification of viability of this implementation in Buenos Aires.
