Commitment to Sustainability

Respect for the environment is part of the values we believe in. Therefore, we seek sustainable means for the execution of all our processes.

Certification in Renewable Energy

Based on several measures, we reduced our CO2 emissions by 105,305 tons and started using photovoltaic electricity, contributing to environmental preservation and savings.


Over the past 20 years, we have planted and ensured the conservation of more than 2910 trees at our headquarters.

Sustainable Processes

Our tempering heat treatment uses recyclable mineral oil. We monitor all collection steps to ensure proper disposal.


We separate garbage for selective collection, where more than 45 tons of paper and cardboard are recycled annually. We carry out campaigns to collect cans, with donations to APAE.
