Brazil's Minas Gerais launches gas‑based fleet decarbonisation and agro‑waste biometane projects

A coalition of Minas Gerais companies, including Grupo SADA, Cemig Energia Livre, Logás and Gasmig, has begun converting part of the heavy‑truck fleet to natural‑gas‑powered vehicles. The programme incorporates 21 compressed natural gas (CNG) trucks supplied by Grupo SADA and a dedicated gas‑pipeline refuelling network built by Logás, with renewable electricity from Cemig. The initiative, part of Grupo SADA’s Heavy‑Fleet Decarbonisation Programme started in 2024, is designed to cut emissions from road transport, which accounts for about 25 % of Brazil’s transport‑sector CO₂ output. The refuelling station earned a Sustainable CNG Station seal, and the pipeline eliminates the need for tanker‑truck fuel transport, further reducing the carbon footprint.

Meanwhile, Gasmig has opened the country’s largest public bid for biomethane, seeking contracts to purchase up to 250,000 m³ per day of renewable gas produced from agro‑industrial waste in the Triângulo Mineiro region. The project will turn residues from pig farms, dairies, sugar‑cane mills and other agro‑industrial activities into biomethane that can power industry, heavy‑vehicle fleets and household distribution networks. The plan foresees about R$1 billion in investment and roughly 400 km of pipeline, targeting supply for nearly one million people. The effort aligns with Brazil’s Fuel of the Future law, which mandates a gradual rise in biomethane’s share of the gas market to 10 % by 2034. Gasmig’s director Rodrigo Pazzini noted that the infrastructure will later be ready to expand the use of biomethane.
