Durante a ABM Week 2026, realizada em S\u00e3o Paulo no in\u00edcio de setembro, a Samarco recebeu o Pr\u00eamio A\u00e7o Verde do Brasil, na categoria Sustentabilidade, pelo desenvolvimento do queimador Low NOx, tecnologia criada para reduzir a emiss\u00e3o de \u00f3xidos de nitrog\u00eanio (NOx) nos fornos de pelotiza\u00e7\u00e3o em Ubu (ES). A iniciativa refor\u00e7a a atua\u00e7\u00e3o da empresa em inova\u00e7\u00e3o aplicada \u00e0 melhoria cont\u00ednua do desempenho ambiental de suas opera\u00e7\u00f5es. O trabalho, apresentado em artigo t\u00e9cnico do engenheiro especialista Raphael Dias de Medeiros e equipe, foi desenvolvido em parceria com a empresa de engenharia ATS4i, com valida\u00e7\u00e3o do Instituto de Pesquisas Tecnol\u00f3gicas de S\u00e3o Paulo (IPT) nas medi\u00e7\u00f5es dos testes piloto.<\/p>\n

O NOx \u00e9 um grupo de gases formado na maioria dos processos de combust\u00e3o, industriais e veiculares. Na Samarco, essas emiss\u00f5es j\u00e1 est\u00e3o consideravelmente abaixo dos limites da legisla\u00e7\u00e3o ambiental vigente. Isso porque, para o gerente de Engenharia de Processos, Felipe Morato, a Samarco busca ir al\u00e9m das exig\u00eancias regulat\u00f3rias. \u201cEm conformidade com a legisla\u00e7\u00e3o e pautada pela melhoria cont\u00ednua de seu desempenho ambiental, a empresa contribui para a redu\u00e7\u00e3o ainda maior de suas emiss\u00f5es\u201d, afirmou.<\/p>\n

\"Equipe<\/a>
Equipe do Projeto Low NOx com um dos queimadores em Ubu – Pedro Villela (ATS4i), Leandro Serafin, Jos\u00e9 Roberto Eg\u00eddio e Jos\u00e9 Luiz Alves, todos da Samarco – Samarco Divulga\u00e7\u00e3o<\/figcaption><\/figure>\n

Desde 2022, as equipes da Samarco, com apoio da ATS4i, desenvolvem um modelo termodin\u00e2mico e simula\u00e7\u00f5es de fluidodin\u00e2mica computacional (CFD) capazes de prever a forma\u00e7\u00e3o de NOx e apoiar o redesenho dos queimadores dos fornos. Ap\u00f3s a simula\u00e7\u00e3o, um prot\u00f3tipo foi testado em escala piloto no forno n\u00ba 4, em Ubu, com envolvimento das equipes de Opera\u00e7\u00f5es, Manuten\u00e7\u00e3o, Instrumenta\u00e7\u00e3o e Automa\u00e7\u00e3o. Os resultados, validados pelo IPT por an\u00e1lise cont\u00ednua dos gases de combust\u00e3o, mostraram redu\u00e7\u00f5es de 15% a 37% na emiss\u00e3o de NOx, conforme a vaz\u00e3o de \u00e1gua utilizada, com impacto controlado no consumo de g\u00e1s natural.<\/p>\n

Comprovados os resultados, a tecnologia avan\u00e7ou para a escala industrial, e o gerente de Opera\u00e7\u00f5es, Gabriel Rossoni, assumiu como respons\u00e1vel executivo pelo projeto. Atualmente, 16 queimadores Low NOx operam na Usina 3 e outros 16 na Usina 4, com amplia\u00e7\u00e3o gradual conforme a valida\u00e7\u00e3o de novos testes. A fase atual \u00e9 conduzida pela equipe de Opera\u00e7\u00f5es, em conjunto com as \u00e1reas de Engenharia, Manuten\u00e7\u00e3o, Automa\u00e7\u00e3o e Instrumenta\u00e7\u00e3o, que tamb\u00e9m otimizou os sistemas de medi\u00e7\u00e3o utilizados no acompanhamento dos resultados.<\/p>\n

\u201cEsse trabalho mostra que o compartilhamento de informa\u00e7\u00f5es e o trabalho em equipe s\u00e3o fundamentais para atingir bons resultados. Envolvemos v\u00e1rias equipes dentro e fora da Samarco, e n\u00e3o existe solu\u00e7\u00e3o pronta: \u00e9 preciso ter v\u00e1rias pe\u00e7as para contribuir com a melhoria do meio ambiente, que \u00e9 o nosso objetivo maior\u201d, afirma Raphael Medeiros.<\/p>\n

O queimador Low NOx integra o programa de Pesquisa, Desenvolvimento e Inova\u00e7\u00e3o (PD&I) da Samarco e refor\u00e7a a estrat\u00e9gia de aliar sustentabilidade e efici\u00eancia operacional, em conson\u00e2ncia com as diretrizes ESG do setor de minera\u00e7\u00e3o.<\/p>\n
