Evaluation of the process and results

The corporate goal of zeroing disposal of industrial waste in landfills by 2030 was internalized in the planning for all units. Each of them uses performance indicators to monitor the generation and proper disposal of their waste monthly, defining actions to reduce generation or projects that seek better technologies/alternatives for the waste disposal.

In addition, Klabin’s units have a continuous improvement program and, together with the ISO 14001 certification, periodically undergo internal and external audits to assess the management system, including the management of solid waste and verification of the achievement of goals and the action plan.

All units have an inventory of solid waste, based on the characteristics of the waste, including: weight, classification according to NBR 10004, costs and revenues, and destination. Most of the waste is controlled by weight on scales in kilograms or tons.

The management of this process also relies on tools and software. Weights are recorded and consolidated on Klabin’s indicator management platform, where it is possible to perform critical analyses and identify destinations and deviations, thus allowing an adequate management of solid waste. The units report waste inventories according to the standards and legislation of environmental, state and federal agencies.

Measures taken to manage significant impacts

In In 2020, Klabin recorded a solid waste reuse rate of 98.3%, an increase of 2% compared to the 2019 index. Based on the principle of reducing the waste generation, the initiative of the Betim Unit is a good exemple. Since the installation of the new effluent treatment plant (ETE), there has been an improvement in sludge dewatering. The reduction in the generation of physical/chemical waste reached 3% in the last quarter of 2020 compared to the same period of 2019.

Actions for greater recovery of sludge from the effluent treatment plants were fundamental to achieve this result, reinforcing Klabin’s commitment and focus on reaching the goal assumed publicly in 2020, of zeroing industrial waste disposal to landfills by 2030.

Waste managed by third parties

When hiring third parties for Klabin’s waste management, the Company’s performance and legal requirements are defined. In order to verify these requirements, in addition to the routine monitoring of the waste transportation and disposal operations, the contracted third parties undergo frequent environmental audits, conducted by Company professionals, for the purpose of identifying technical qualification, improvement opportunities and adaptations to meet the requirements of Klabin and/or legal requirements.

Collection and monitoring of data, standards and tools
All units have an inventory of solid waste, based on the characteristics of the waste, including: weight, classification according to NBR 10004, costs and revenues, and destination. Most of the waste is controlled by weight on scales in kilos or tons.


The management of this process relies on tools and software. Weights are recorded and consolidated on Klabin’s indicator management platform, where it is possible to perform critical analyses and identify destinations and deviations, thus allowing an adequate management of solid waste. The units report waste inventories according to the standards and legislation of environmental, state and federal agencies.

Performance analysis
In 2020, we reused 98.3% of solid waste, an increase of 2% with respect to the 2019 index. The actions for greater recovery of sludge from the effluent treatment plants were fundamental in achieving this result and reinforce the commitment and focus on reaching the goal assumed in 2020, of zeroing industrial waste disposal to landfills by 2030.

Between 2019 and 2020, we advanced in research and development for waste disposal based on the circular economy, such as the partnership signed between the Rio Negro-PR unit and the region’s ceramic industry, which now receives the sludge from the Effluent Treatment Plant (ETP) for incorporation into bricks. This initiative is being studied for expansion to other Klabin units.

Other initiatives for waste management that deserve to be highlighted include:
– Use of dregs (one of the wastes from the chemical recovery of the process) and sand from the fluidized bed of boilers, waste from the Monte Alegre and Puma units, in the production of civil materials such as pavers, shackles, hexagonal flooring, curbs and fence posts;
– Use of waste from the chemical recovery of the process (dregs and burnt lime), sand from the fluidized bed and ashes from the biomass boilers, at the Monte Alegre and Puma units, in the production of sub-base for forest roads;
– Use of ash from the biomass boiler at Otacílio Costa as soil conditioner in forage plants in the region;
– Use of sand from the biomass boiler, sludge from the ETP, dregs and grits (chemical recovery waste) from the Correia Pinto unit and sludge from the Lages Unit’s ETP for the production of sealing blocks;
– Study for the production of bio-oil and biochar using forest waste from the Santa Catarina forestry unit.

Waste Management

Klabin’s operation, in all of its businesses, generates solid waste, whether due to human activities or remnants from production processes. Klabin strives for the most efficient production possible with the least amount of remnants and for the reuse of process byproducts. When internal recovery cannot be performed, waste is destined for recycling and external recovery, and to ensure a good recycling rate, procedures are maintained and the proper internal segregation of waste is constantly verified.

The potential significant impacts related to the waste are generated in the organization’s activities and in the value chain. The production process begins with the management of eucalyptus and pine forests, after the trees are processed in the field, they are transported to the pulp and paper production units and when they are debarked, they generate bark that, along with forest waste, is burned in the steam boiler of these units.

For conversion of the wood into pulp and paper, the main waste generated are sludge from the treatment of effluents and residues from the chemical recovery stage of the soda used to extract cellulosic fibers from the wood, most of which is recovered for agricultural use.

The pulp produced is transported directly to conversion customers and part of the paper produced is transported to Klabin’s packaging plants and the other part is sold to customers, where it is converted into packaging. At this stage of conversion, the leftover paper (refiles) is generated, which, along with the chips purchased from the market, are used for the production of recycled paper. In addition to this waste, others generated in greater quantity are the sludge from the treatment of effluents and tailings from the process to prepare the chips for production.

Items 6, 7, 10 and 12 of Klabin’s Sustainability Policy encompass, respectively: pollution prevention through the reduction of the impacts of solid waste generation; the search for the most efficient technologies and solutions; guidance on the topic in accordance with the SDGs; and compliance with legislation and standards applicable to the product, environment, health and safety. Environmental management is also based on the guidelines set forth by ISO 14001, in which the majority of our units are certified.

In addition, it is worthy to say that all units undergo an internal audit by a team from Klabin itself. Those units that are certified carry out internal audits through the management system. The units that have not yet been certified (22% of the total) also undergo internal audits regularly, conducted by Klabin’s team, which holds the ISO 14001 standard auditor certificate. Thus, these units are being prepared for the formal audit, scheduled for 2022.

In addition to internal guidelines and policies, federal (Law No. 12.305/2010 – National Policy on Solid Waste), state and municipal legislation related to solid waste are constantly monitored, accompanied by actions to demonstrate compliance with the guidelines of these standards.

Environmental indicators are a pillar considered when calculating bonuses for employees and senior management.

The topic is also included in the Klabin 2030 Agenda, a sustainability roadmap in line with the Company’s growth plan.
