For over 35 years providing innovative solutions for our partners.

For more than 35 years we have been developing solutions for biomass. We started in 1990 as a small business, but with a strong drive to reach the world with our solutions. Over time the market evolved and Dujua did too; there were many investments in infrastructure, employee training, process structuring and innovation to deliver production excellence, rely on committed professionals and establish the partnerships we have. More than partnerships, we create bonds of respect, trust and collaboration.

“Throughout its history, DUJUA has been present throughout Latin America, taking its technology and solutions to different locations”

The company is proud to have participated in major projects and to be helping to shape this market on a daily basis. With capability and hard work, the company expects to help many partners and friends along its path.
