The process of nixtamalization consists in the transformation of corn into a nutritionally richer product that can then be used to make tortillas and other corn products.

This process uses up to 6 millions of cubic meters of water per year, and the water couldn't be purified and reused.

GRUMA improved its water treatment process to be able to reuse up to 90% of the water wasted in the process, and by reusing this water they were able to make a product with improved nutrients.

This translates into 5.5 billion liters of water saved per year only by GRUMA, while also avoiding the disposal of used water in rivers that could pollute bigger masses of water.

GRUMA continues to invest to reuse up to 97% of this water in the future.

Saving Water Through Nejayote


The uncontrollable amount of water needed for the process was causing an impact in the ecosystem that was near the plants that had this nixtamalization process. They needed a more sustainable process that wouldn't destroy its surroundings.

Overall impact

The overall impact of this innovation is:

  • 5.5 billions of liters of water saved annually.
  • Corn with higher nutrients.
  • Sustainable production plants.

Business benefit

The benefits of this innovation to the business include:

  • Up to 4 million dollar savings per year in water.
  • Avoidance of environmental fines.
  • Cleaner and more sustainable process that makes them more competitive.

Social and environmental benefit

The benefits to society and the environment are:

  • Pollution reduced in the surroundings of the production plants.
  • 5.5 billion liters of water saved anually.
  • Jobs created in the new treatment process.
  • A sustainable process that could be improved even more (GRUMA is investing in this)

The process of transforming corn into tortillas uses thousands of millions of liters of water each year.

Through innovation in the treatment of water that is used in the process, they are able to reuse it and save 90% of the original consumption and obtain products with better nutrients.
