Objective:

To analyze low-cost technological alternatives for the use of whey through the economic valorization of by-products, in cheese factories of Miahuatlán, Veracruz.

Methodology:

The cost-benefit analysis was carried out to evaluate three possible scenarios. The first considered the option applied in the last five years; the second scenario used the low-cost alternatives proposed; and the last one took mixed alternatives from the first and second scenarios.

Results:

The scenario with diversification of alternatives is the most efficient for the valorization of the whey, because it would generate economic benefits for the producers and would reduce the risk of contamination by whey residues.

Limitations:

To implement the proposed alternatives, producers must change their production processes, which guarantee quality serum for proper processing.

Conclusions:

The implementation of diversified technological alternatives for the use of whey in low-cost by-products is feasible for rural localities, based on the producers' local interest and knowledge.
