Klabin made significant progress in its renewable energy matrix indicator. There was a reduction in the consumption of non-renewable fuels such as fuel oil in the pulp and paper units and natural gas in recycling operations.
One of the highlights is the Ortigueira Unit, which operated the biomass gasification plant, generating fuel for supplying one of the lime kilns and contributing to the reduction in fuel oil consumption at the unit. The result was significant growth in the Company's renewable energy matrix, reaching over 92% of the total.
Klabin remains committed, investing in research, development, and innovation to replace non-renewable fuels. In addition to the progress already achieved, it highlights the conduct of three industrial-scale tests for using bio-oil in the lime kilns at the Monte Alegre Unit, replacing 100% fuel oil.

In 2023, 100% of all electricity consumed at the units located in Brazil came from renewable sources, and this was certified by purchasing IRECs and self-declarations. As a result, if this indicator result repeats in the next year, the target will no longer be considered a general goal but will be internalized as a standard process.

In 2023, for the Pulp business, the PUMA unit operated with the biomass gasification plant as fuel for one of its lime kilns, contributing to the reduction of fuel oil consumption at the unit. For the recycled business, there was a significant reduction in Natural Gas consumption due to changes in the strategic planning of the company's Recycled business.

Risks and opportunities associated with the use of biomass as an energy source
The biomass used at Klabin to generate energy comes from forestry waste, which reduces the risk of shortages. Planning takes into account: (i) demand and supply; and (ii) price volatility, to control and mitigate possible risks of shortages. Another point to consider is investment in technologies such as the biomass gasification process, which came into operation in 2022 to optimize resources.
The document Guidelines for Climate Change Management – Adaptation and Mitigation brings together the Company's guidelines for environmental and climate change management and the promotion and encouragement of energy efficiency. At the Ortigueira Unit, the Internal Energy Conservation Committee (CICE) is made up of employees and is responsible for looking for opportunities to reduce the consumption of energy, steam, and compressed air, as well as eliminating waste.
Klabin is engaged in energy production and a progressive increase in the renewable energy matrix, produced from biomass and black liquor. 68% of the total electricity consumed comes from self-generated thermal and hydraulic sources, while the rest is purchased from the system, with 100% coming from renewable sources.
Energy efficiency is one of the focuses of Klabin's environmental management, which is continuously concerned with optimizing energy consumption at industrial plants.
The energy generated by Klabin is predominantly from renewable sources, accounting for 92.6% of the total. In 2023, the Ortigueira Unit sold 491,747.60 MWh to the National Electric System, representing 14% of the total electricity produced by Klabin.
Management system
Since 2022, the Energy Committee has been part of Klabin's management system. The committee, consisting of a multidisciplinary team, aims to strategically develop innovative actions and map opportunities for the evolution of the topic and, consequently, of the Company's results and indicators.
The Ortigueira Unit is ISO 50001:2018 certified for its Energy Management System and maintains an internal and external audit routine. In addition to the public goals of the 2030 Agenda, energy generation targets are also taken into account, as one of the criteria for the employee profit-sharing program at the unit.
In 2020, the Tall Oil* plant of the Ortigueira Unit came online, increasing the share of renewable fuels in the energy matrix. In 2021, Puma II began operating, with the biomass gasification plant starting up in March 2022.
In 2023, Klabin achieved 92.6% of its energy matrix from renewable sources. The start-up of biomass gasification at the Ortigueira Unit in 2022 and the increase in bio-oil consumption at the Correia Pinto Unit contributed to replace fuel oil consumption, increasing the share of renewable fuels.
The other industrial units follow the control and monitoring of the energy indicator in accordance to ISO 14001 certification.
*Tall oil is a byproduct of pulp production, obtained from the separation of tall oil soap from burned black liquor to generate steam and electricity.
