Tsubame BHB Co., Ltd (Tsubame BHB) has signed a letter of intent (LOI) with ATVOS AGROINDUSTRIAL PARTICIPAÇÕES S.A (Atvos) regarding a green aqueous ammonia factory in Mineiros, Brazil, where Atvos's morro vermelho unit (UMV) is located, responsible for ethanol production.
The new plant will have an installed capacity of 20 000 t of the product. It will be used to replace fossil-based fertilizers applied to agricultural areas at both the UMV and the alto taquari unit (UAT), located in Mato Grosso, Brazil. With this solution, Atvos estimates it will avoid the emission of approximately 11 000 tpy of CO2, significantly reducing its carbon footprint.
The execution of this LOI was witnessed by Japanese Prime Minister Shigeru Ishiba and President Luiz Inácio Lula da Silva of Brazil, at the Japan-Brazil Economic Forum held in Tokyo, Japan, on 26 March 2025. On 28 March 2025, Caio Dafico, Investment and Business Development Vice President at Atvos, visited Tsubame BHB for a tour of the pilot plant, and to conduct discussions on future directions for the project.
Tsubame BHB will further accelerate its efforts to secure this first order for an overseas unit, and to rapidly promote overseas deployment.
Atvos CEO, Bruno Serapião, said:, “Atvos seeks to contribute to the decarbonisation of the globe's leading economies while also reducing the carbon footprint of its own operations. Thus, the partnership with Tsubame to produce green ammonia represents a significant step toward achieving this goal, as it will enable us to reduce the use of fossil-based nitrogen fertilizers and further strengthen our commitment to fostering the social and economic development of the countryside cities through job and income generation.”
Tsubame BHB CEO, Koji Nakamura, added: “Brazil has potential to become a major producer of green hydrogen, by leveraging its abundant renewable energy resources, and it is also a major agricultural nation that consumes nitrogen-based fertilizers in high volumes. As such, I believe that it is one of the countries that can manufacture green ammonia as a fertilizer at the small distributed ammonia synthesis plants offered by Tsubame BHB. I hope that through this collaboration, we can contribute to the decarbonisation of agriculture in Brazil.”
