The generation of energy based on fossil fuels has caused severe damage to the environment. The use of pig manure to generate renewable energy and revert contamination problems is a viable alternative for the Chiapas pig farms to be more competitive and to obtain better profits. A total of 39 technified pig farms distributed in 14 municipalities in the state of Chiapas were identified and the potential for biogas, electric energy and carbon dioxide equivalent (CO2e) reduction was estimated. In addition, a financial evaluation was made for biodigestor-motogenerador system for the most suitable sizes for Chiapas that are 500 and 1000 pigs. The 39 farms have a potential of 5,381,925 m3 biogas per year, a reduction of 29,167 t CO2e and a potential of 7,593 MW of electrical energy. For farm size of 500 pigs, a Net Present Value (NPV) of $ 5,994, Internal Rate of Return (IRR) of 13.5% and Benefit Cost Ratio (B/C) of 1.7 was obtained; while for the size of 1000 pigs a NPV of $ 206,217, IRR of 17.4% and B/C of 1.9 was obtained.
