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.

62.00% 96.60% 99.91% 99.88% 100%


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 guidelines for environmental and climate change management and the promotion and encouragement of energy efficiency at the company. At the Ortigueira Unit, the Internal Energy Conservation Committee (CICE) is made up of employees and is responsible for seeking opportunities to reduce the consumption of energy, steam, and compressed air, as well as eliminating waste.  

Since 2022, the Energy Committee has been part of Klabin's management system. The body, made up 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. 

Audits to identify opportunities to improve energy efficiency 


Currently, 100% of Klabin's units receive audits on the Environmental Management System, including energy consumption and identifying opportunities for improvement. Of particular note are 78% of the operations which are ISO 14001 certified and the Ortigueira Unit which has ISO 50001:2018 certification for its energy management system, maintaining internal and external audit routines. 

Measures adopted to optimize energy use  


Energy efficiency is one of the focuses of Klabin's environmental management, which is continually concerned with optimizing energy consumption at industrial plants. 

  In 2020, the Ortigueira Unit's Tall Oil* plant went into operation, 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. 

  By 2023, Klabin will have achieved 92.6% of its energy matrix coming 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 have contributed to replacing fuel oil consumption, increasing the share of renewable fuels. 

The other industrial units control and monitor the energy indicator by ISO 14001 certification.  

*Tall oil is a by-product of pulp production, obtained by separating tall oil soap from the black liquor burned to generate steam and electricity.  

Expanding the use of renewable and clean energy 


Klabin is committed to energy production and to progressively increasing 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.   

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 electricity system, 14% of the total electricity produced by Klabin.  

Investments in innovation, research, and development  


In line with investments in research and development for energy efficiency, in 2023 three industrial-scale tests were carried out to use bio-oil in the lime kilns at the Monte Alegre Unit, replacing 100% of the fuel oil. 

Employee awareness measures 


Klabin's units continuously participate in the Superar Program, which adopts a management methodology based on the TPM (Total Productive Management) model. Among the aspects dealt with in the program are energy and water consumption and waste generation and disposal. According to the profile of each unit, awareness-raising/training actions are carried out to make progress on the opportunities for improvement identified (focus on operational efficiency). 

Targets associated with energy use 


Klabin has two targets associated with energy use, which can be found in the 2030 Goals Chapter.
