Get to know our history
Founded in 2013, ABMT started out with the intention of selling and refurbishing electrical transformers. In 2015, after winning a contract to recycle transformers in Piauí, the company expanded its operations to recover other materials that make up transformers, such as mineral oil, copper, aluminum, ferrous and non-ferrous materials.
In 2020, it began expanding its factory structure and, the following year, doubled its fleet of trucks. Also in 2021, it signed its first international contract. Finally, in 2023, it signed a contract with one of the country's largest electricity utilities.
With a team of highly qualified and experienced specialists, ABTM prides itself on offering efficient and sustainable recycling solutions for the industrial sector. With quality and safe services, we contribute to a more conscious and sustainable future!
