Our activities have no significant potential
impact on the environment due to the waste
generated, mainly ash from coal-fired power
plants, followed by clay gravel, resulting from the
drilling of natural gas wells, but of little relevance.
Nevertheless, to comply with the National Solid
Waste Law and standardize the activities over
the entire management process, from generation
to final disposal, we adopted a corporate Waste
Management procedure starting in 2020. It aims
to ensure the correct segregation, for temporary
storage, transportation and economic and
environmentally appropriate final disposal.
In the year, due to the higher dispatching of the
mineral coal assets, we registered a 79% increase
in the ash generated by the activity, and 100%
of this waste is prepared to be sold and reused
by the cement industry, without environmental
impacts and encouraging the circular economy,
fundamental in sustainable businesses.
The initiative of reuse of ash by the cement
industry replaces the use of clinker in cement
production and since 2016 has already indirectly
contributed to a reduction of 231,000 tCO₂,
through the reuse of 256,000 tons of ash. These
quantities refer to the ash generation at Pecém
IITPP.
In 2021, we generated a total of 118,500 tons of
waste, considering waste of classes I, II and III. Of
this total, 81% represent our generated ash and
we registered 90% in our Sustainable Destination
Index (IDS). In 2021, 82,900 tons were destined
for recycling, composting and/or co-processing,
and another 9,200 tons were destined for
industrial landfills or other purposes.
The year included the introduction of the Solid
Waste Management procedure in six new
corporate and operational indicators in the
Health, Safety and Environment Management
System, which seeks to cover all the details in
the management routines, locally.
The management of the entire process is
further qualified through a waste inventory
that is prepared monthly for each unit by our
Operational Environment area, as defined by
internal procedures. In addition, each quarter this
control is presented to the Corporate Environment
area, for the consolidated analysis of the results
and treatment of eventual non-compliance issues
through preventive and corrective actions in all of
the company's operating units.
The process of segregation, classification, and
packaging is our responsibility, while the final
disposal is the responsibility of a contracted and
duly licensed company. All of these management
82.9 thousand
tons were destined for recycling
9.2 thousand
tons destined for industrial landfills or
other purposes
procedures are compiled in a Solid Waste
Generation and Disposal Inventory, per unit,
containing the mapping of the waste from the
generating process to the type of final disposal.
We also use a Waste Transport Manifest Control
(MTR) containing the classifications according
to the applicable standards and legislation, duly
registered in the Ministry of the Environment's
SINIR system.

temporarily stored in the yard for correct disposal in 2022. GRI 102-48
