We dispose of the waste generated in our operations responsibly and in compliance with all legal requirements. We want to be capable of offering our waste a destination that allows greater circularity, enabling it to be used in other production chains. Thus, we seek sustainable technologies and solutions applicable to industrial residues, which we used to send to our landfills and third parties to promote new uses, such as transforming them into soil acidity correctives and other agricultural inputs. Currently, our forestry operations already use this solution and we have managed to reincorporate in the process that was previously discarded. Furthermore, we use part of our waste as biomass to generate energy (energy recycling) and we have an area in our organizational structure dedicated to selling these byproducts to other industries.

Waste sent to specific landfills (kg/t), considering the total industrial waste sent (kg) per ton of saleable pulp and paper from all Suzano's industrial units. Considers all the waste sent to landfills owned by Suzano and third parties, corresponding to non-hazardous inorganic industrial waste, such as grids and lime mud, and organic waste, such as primary and biological sludge.

In 2022, we have reached 18.4 kg/t, which represents an advance of 84% about the baseline of the Commitment. The year's main highlights are the composting project consolidation at the Mucuri Unit (BA), which reduced its indicator by 21%, from 59.8 kg/t in 2021 to 47.1 kg/t in 2022. Each month, 10 thousand tons of organic waste are generated at the unit, which is no longer sent to landfills and is now composted in partnership with a specialized company, transforming the waste into fertilizer. We also had a significant improvement in the Imperatriz Unit (MA) because during rainy periods it was not possible to reuse the primary and secondary sludge as biomass, due to the high moisture content. To solve the issue, a drying oven was implemented. Besides, this material started to be burned in the boilers for energy generation during the rainy months.

The Non-Operating Items Sales area (VINO) sold 490,000 tons of waste and byproducts from pulp and paper manufacture, which were initially treated as waste, but have the potential for use as raw material for other industries. As a highlight, 125,000 tons of by-products containing fibers were reused and no longer disposed of in industrial landfills.

In recent years, we have invested BRL 72 million in the construction of waste treatment centers at the Três Lagoas (MS) units, which have been operating at full capacity since the end of 2020, and Imperatriz, which went into operation in the first quarter of 2021.

The Jacareí (SP), Limeira (SP), and Rio Verde (SP) Units stand out for remaining without sending waste to landfills. 

We will deepen the Technical and Economic Feasibility Studies for the installation of Correction Plants at the Aracruz (ES) and Mucuri (BA) Units. We will also continue to develop studies to find alternatives for the disposal of waste from Suzano's units, including the use of by-products in the manufacture of concrete, cement, and agricultural applications.
