Forestry operations are performed Celulose Irani in western Santa Catarina and the coast of Rio Grande do Sul.


As the main management tool for planning and control, the IRANI Forestry Unit has a Geographic Information System (GIS).

The GIS allows for the manipulation of the information needed to plan, the environmental adaptation, control of payments to suppliers and subcontractors and the tracking of the raw materials from the forest to the delivery in the industry.

The unit also uses as a tool for planning and control, the Forest Inventory, which provides information on the wood inventory in the forest. This document helps in the planning of forestry production, to optimize the management of forests and with the Company´s strategic decisions.

Since 2008, all of the Company´s own forests in Santa Catarina are FSC® certified, which ensures that the handling and management complies with their requirements and internationally recognized principles. Thus, about 60 to 70% of all wood used in pulp production is certified. The remainder is considered as being derived from controlled sources and are evaluated in relation to the Wood Purchasing Policy, its origin and social and environmental requirements.

» Public Summary - Forest Management Plan SC

In the forestry areas in Rio Grande do Sul, IRANI has a georeferenced mapping system of all municipal nurseries, operated by satellite imagery and Arc View software.

This system is an important tool for the planning, management and execution of forestry operations. The mapping identifies and delimits the boundaries of the property, the areas of planted forests, demarcation of plots, roads and firebreaks, water resources, improvements, native forests and other elements considered as important for the management.

This information is also provided to guide the activities necessary for the full compliance with applicable laws and the Company's Environmental Policy.

The planted forests in Rio Grande do Sul are based on the Pinus elliottii species. Therefore, there is a system of forestry management and silvicultural practices, aimed at the production of solid wood and resin.

In the planting areas, the operation of the forest after the clearing of the original forests occurs through a management system and the natural regeneration of newly born Pinus. In exceptional cases, the Company promotes the densification of new plantings or seedlings.

These are produced incrementally to meet the commercial demands of the Company, in terms of quantity and quality.


The IRANI plantation cycle of the forests starts with the collection or the purchase of seeds from selected trees with superior genetic material, which are sent to the Company´s own forestry nursery in Vargem Bonita - SC.

The annual production capacity of the IRANI nursery in Santa Catarina is approximately six million seedlings, of these are about one million are Eucalyptus and five million of Pine.

In addition to planting the main commercial species, Pinus and Eucalyptus, Celulose Irani grows native plants seedlings such as Araucaria, Walnut and other species that are native to the region that are mainly used in the recovery of degraded areas, enrichment of forests that are in the early stages, and donations in the socio-environmental activities in which the Company participates and carries out in the surrounding communities.

The Pinus and Eucalyptus seedlings are delivered to the field after reaching the desired standard of development. The planting of Pinus is carried out throughout the year; however, Eucalyptus is planted in the months when the likelihood of frost is remote, especially from October to December.

The production stages - from soil preparation to transport of timber after being cut - are carried out by subcontractors, who use techniques and care that contribute to the reduction of generated environmental impacts.

The management cycle, from planting to the final cut, is 15 years for pine and seven years for eucalyptus. Thus, IRANI obtains in both cases, high levels of productivity, and the quality desired for the manufacture of its products.

The conservation of the forest contributes to the balance of the environment and helps in the biological control of pests and diseases.


For 21 years, Celulose Irani has carried out a program to fight the Sirex woodwasp (Sirex noctilio) by means of biological control. The Company monitors the presence of attacks and the index of parasitism, preventing possible economic damages, in addition to maintaining the health of their crops.

Besides the Sirex woodwasp, IRANI monitors in Rio Grande do Sul the appearance and the action of the leafcutter ant on newly formed forest. Combat is usually carried out 15 days before planting. The Company is registered with the Fundo Nacional de Controle à Vespa-da-Madeira (Funcema) (National Fund for Control of the Sirex woodwasp) and the Programa Nacional de Controle da Vespa-da-Madeira (PNCVM) (National Programme for Control of the Sirex woodwasp)and contributes to the maintenance of this program and meetings and technical workshops related to management of Pinus with visits to control these pests.

Preventive actions are carried out by Irani on the community areas surrounding forestry areas of Santa Catarina and Rio Grande do Sul, in order to educate people about caring for the use of fire and possible environmental and economic damage caused by fires.

The company has also cleared firebreaks in risk areas in Santa Catarina and Rio Grande do Sul. The IRANI Forestal Fire Brigade is responsible for the combat in any outbreak of fire. The team is constantly trained by the firefighters from the region and it has its own equipment, including a fire truck. In Santa Catarina, the Company has a cooperation agreement with the Volunteer Fire Department of the City of Irani - SC that provides assistance in cases of loss.

Surveillance is done by guardians who reside on farms and monitor the property, prevent predatory actions fauna and flora, and control the access of visitors. Irani has also has a partnership with the Environmental Police of Santa Catarina, with the aim of cooperation in the monitoring and environmental education to preserve, conserve and improve the environment in areas operated by the Company.

Another control and monitoring measure in these areas is the fishing procedure in reservoirs and rivers that cross the IRANI properties, in Santa Catarina. In this procedure, fishing is permitted by the application and registration of visitors. This practice, in addition to benefiting the community as a leisure option, nurtures the awareness of users about environmental issues, highlighting topics such as spawning, conservation of water resources and the environment.

With other measures of impact management, the Company seeks to be an ally of the conservation of biodiversity in regions where it operates. It also performs preventive and mitigating actions of the possible impacts resulting from their activities. 

The Forestry Unit has established partnerships with research institutions to develop joint activities in the areas of Forest Improvement, Forest Protection, Forest Management, Biodiversity Conservation, The Soil/Ground, among others areas.

IRANI carries out and supports research with the potential of generating more knowledge of the interaction between the flora and fauna and planted forests, aiming at improving the management methods and enabling the definition of environmental indicators for the management.

The following studies are either underway or have done recently:

Studies carried out in Rio Grande do Sul

Seeking to widen the knowledge about the environmental impacts of their activities and act in a broader way to minimize or eliminate these impacts, IRANI, in partnership with the Federal University of Rio Grande do Sul (UFRGS), has been carrying out since 2008 research on the effects environmental management of Pinus elliottii in Rio Grande do Sul.

In this study, the evaluation of the aspects of the management of these species as a potential for dispersal, allelopathic potential, carbon sequestration in resin forests and the study of species associated with pine forests.


Guided by self-sustaining production, the Celulose Irani SA Forestry Unit encourages reforestation to ensure the supply of wood needed for the expansion of the business, to integrate the small farmers and provide an alternative income for those who become partners in this activity. 

The Rural Partnership Program benefits the population of the West of Santa Catarina, generating jobs and contributing to growth in the region.


In the Rural Partnership Program, the producer offers IRANI areas of land for cultivation. The Company does the planting and the operation of the forest until felling. At the end of the rotation, the forest production is divided between the parties, and the percentage defined according to the distance between the IRANI property and the characteristics of each planting site.

The Forestry Unit, when the areas are chosen, takes into account the distance to the factory in Vargem Bonita - SC, the topography, the previous use of the land, the need to use heavy machinery for soil preparation, the expected forestry performance and the ease of adaptation to current environmental standards, besides the owner's willingness to accept these adjustments.

As Celulose Irani complies with the Brazilian environmental legislation and requires the same from its partners, the average use of rural properties for economic purposes is around 50%. The average area is ​​50 hectares and the company already has 3,230 hectares planted in partnership with 66 properties.

IRANI also sells wood to supply the various market segments in areas where it operates forests. In Santa Catarina, the Company sells mostly pine logs to sawmill and plywood segments. In Rio Grande do Sul it sells round posts and logs to sawmill and panel segments.

Another way to encourage reforestation in the region is through the acquisition of part of the supply of wood for the production of pulp and energy (biomass) in the regional market.

The process of buying wood in IRANI, besides normal trading procedures (price, quantity, registration, quality specifications), consists of supplier risk analysis carried out by company professionals who have been trained for this purpose.

To meet the FSC® chain of custody certification for Paper and Packaging industrial units, the origin of the wood used in the process, when not certified, should consider five basic principles - standards – of the FSC, which are translated by the Wood Purchasing Policy.

Through a questionnaire accompanied by evidence (documents, declarations of ownership, legal opinions, etc.) and visits to the area, IRANI evaluates the risk conditions and the possibility of purchase.

The Wood Purchasing Policy is an instrument that, in addition to guiding procedures, provides transparency in the decision to comply with the environmental, social and economic questions.

Celulose Irani SA acquires wood and pinus chips for the Kraft pulp and chemi-mechanical pulp processes and implements efforts to avoid buying these products from controversial sources, in accordance with the FSC®.
The Company undertakes to:

1 not acquire illegally harvested timber;

2 not to purchase wood harvested in violation of traditional and civil rights;

3 not to purchase wood from forests where high conservation values are threatened by forest management activities;

4 not to purchase wood from native forests being converted to plantations or non-forestry use;

5 not to purchase wood from forests where genetically modified trees are planted

IRANI has significant conservation areas of typical native forests and natural formations in the properties where it operates its forestry operations, ensuring the balance between production areas, consisting solely of planted forests.

The integrated production of planted pine and eucalyptus forests with native forests, through appropriate forest management processes, contribute to biodiversity conservation, generates economic development due to the high productivity of planted forests, and reduce levels of greenhouse gases in the atmosphere by sequestering carbon.

In Brazil, according to the Brazilian Association of Pulp and Paper (Bracelpa), 100% of the production of pulp and paper as its source, planted eucalyptus and pine forests. In these forests, the trees are grown in specific areas, with high quality inputs, and then they are harvested for industrial use. Then, a new forest is planted to perpetuate the planting and harvesting cycle.

The management of planted forests in IRANI occurs through successive planting cycles, as well as ensuring renewable raw material to manufacture its products, contributes to the conservation of native forests and the preservation of local biodiversity.

By having a large volume of planted forests, IRANI, through the Greenhouse Gas - GHG emissions inventory has become a Carbon Neutral Company, by removing more carbon from the atmosphere than it emits.

Considered as true carbon sinks - each hectare captures about 27 tons of carbon per year - the fast-growing planted forests play an important role in the fight against global warming.
