Sustainability Report 2004

Sustainability objectives for 2005

Environmental aspects

Compliance with legal requirements

  • Register 40,000 hectares of existing legal reserves.
  • Replant 489 ha of Permanent Preservation Areas (APP) and Legal Reserves (RL); rehabilitate 23 ha of mining areas.
  • Invest in replacing the current system for one that uses the ecological HFC-134a coolant (Barra do Riacho Unit), in order to eliminate the CFC-11 coolant (Freon).
  • Produce and publish the GHG balance for 2005 and register the carbon sequestration project at the Chicago Carbon Exchange (CCX).

Evaluation and monitoring of environmental impacts

  • Produce a birdlife survey and an evaluation of water quality and water table levels in areas owned by the company and Forestry Partners Program participants.
  • Continue effluents monitoring at the Barra do Riacho and Guaíba Units.
  • Produce physical-chemical and biological survey of the areas affected by the Caravelas Marine Terminal, in Bahia.

Management and reduction of environmental impacts

  • Set up two experimental conservation units, one in Bahia and another in Espírito Santo, totaling approximately 1,000 hectares, to experiment conservation models.
  • Set up two experimental restoration units, both in Espírito Santo, totaling approximately 20 hectares, to experiment and develop models for the formation of biodiversity corridors.
  • Produce 768,000 native species seedlings in the Barra do Riacho Unit and 160,000 native species seedlings in the Guaíba Unit.
  • Reduce the water consumption of the Barra do Riacho Unit by 4.5% (400 m 3 /hour) and the Guaíba Unit by 13% (300 m 3 /hour).
  • Implement studies and actions designed to reduce effluents from individual sectors and improve the efficiency of the Effluent Treatment Station, reducing the formation of odor-causing gases during the biological action of the treatment.
  • Undertake the following operational improvements at the Guaíba Unit:
    • Reduce the noise levels from the industrial area, ensuring the maximum limit of 70 dB during the day and 60 dB during the night and eliminating the noise produced by falling wood while being unloaded from trucks in the factory.
    • Eliminate the loss of fibers via the sector effluent from the drying and bleaching machine, increasing the efficiency of fiber recovery from 80% to 85% and recovering 300 tons/year of fibers.
    • Modernize and upgrade the Non-Condensable Gas (GNC) System, minimizing odor emissions and ensuring the non-emission of digestor gases during shutdown situations.
    • Install the Guaíba Unit’s Ash Recovery System, ensuring the release of rainwater effluent with suspended solid values of < 45 mg/l and sedimentable solid values of < 1 ml/l.
    • Reduce the consumption of total active chlorine by 20% (6 kg/tsa) and soda by 40% (10 kg/tsa).
    • Reduce the generation of lime mud by 85% (1,000 ton/month), recycle 100% of the sludge tailings from the ETE and eucalyptus bark
    • Recover the former Morro Maximiliano solid waste class II treatment center and the solid waste class II landfill.

(*) The increase of DQO will result from an increase in production and consequently a more concentrated load at the beginning of the treatment.

In recent years Aracruz has published an extensive list of social and environmental targets. For 2005, the list has been extended to include our commitments to governance and engagement with stakeholders. In addition to expanding the scope of our targets, we have reduced the number of projects and indicators, placing a renewed emphasis on qualitative indicators. Our aim is to provide the reader with a clearer overview of our proposals and a better evaluation of the efforts and results achieved by the Company. The complete evaluation of the targets established for 2004 and those proposed for 2005 can be found on: 2004 Environmental targets.
