DIFFERENTIATION THROUGH
GREEN PRODUCTION
Minasligas is proud to offer the market differentiated products, both
for the quality and safety present in its processes, and for the
management and control of all environmental aspects of our
production process, which we characterize as a "green production" -
clean, safe, with little waste and low GHG emissions.

The carbon footprint of the silicon-based alloy industry is directly related to the energy sources
used in the production process. In Brazil, GHG emissions are already lower than in other
countries. And Minasligas goes even further, bringing the issue to its strategic agenda and
seeking sustainable production.
Through active management, environmental impacts are mitigated using processes, tools and
equipment that make it possible to control the main activities, making them increasingly eco-
efficient, such as:
.
Environmental Management and Risk Management System (ISO 14001);
ENVIRONMENTAL MANAGEMENT
Both the industrial plant and the reforestation farms undergo periodic and systematic assessments of
their environmental aspects and impacts, guided by specific operational procedures of our
Environmental Management.
All facilities (factory, office, farms) are in legal compliance, with up-to-date environmental licensing.
The company is fully regularized in relation to the Solid Waste Management Plan (PGRS).
WASTE MANAGEMENT
Waste classified as hazardous is packaged in accordance with the legislation and sent to a company with
an environmental license to receive and transport this type of material, which is used for energy
recovery. In 2021, all 17.52 tons of hazardous waste (Class 1) were destined for incineration with energy
recovery.
Non-hazardous waste (Class 2) totaled 59,281 thousand tons in 2021. Among these, a total of 35,731
thousand tons of so-called "coal fines" are packaged by Minasligas in accordance with legislation and
sent to a company that has an environmental license to receive and process it for energy recovery.
Other non-hazardous waste destined for co-processing totals 23,549 thousand tons.
There was no volume of mineral waste, hazardous or non-hazardous, destined for landfills.
• Dedusting system in all furnaces;
• Waste Management / Solid Waste Management Plan;
•
Preventive and predictive maintenance on equipment and monitoring of emissions from own
and third-party vehicles.
3Rs Program
Even though it already has efficient Waste Management, Minasligas launched the 3Rs Program in 2021,
which aims to reduce, reuse and recycle the waste generated. This program seeks, together with all
sectors of the company, to encourage the conscious consumption of resources, avoid waste and
optimize processes.
