Eternit believes that achieving solid results depends on balancing an honest and transparent relationship with its stakeholders, caring for natural resources and adequately allocating economic resources. The Company measures its impacts in each operating segment based on the concept of externalities, encompassing positive or negative effects generated in other agents without them controlling such impacts, as shown in the following table.
All subsidiaries follow rigorous safety standards at their industrial plants and also use automatic and enclosed, high-technology equipment to perform these activities. To prevent and mitigate significant potential impacts, SAMA maintains partnerships with outsourced companies for the safety of its activities both inside and outside the plant, which eliminates any negative impacts on the community and on the industrial unit.

The Integrated System Policy (PSI) serves as the foundation of Eternit’s environmental management by combining policies, practices and procedures in social and environmental responsibility. The Group works in harmony with all of its stakeholders to raise awareness on the need to reduce the consumption of natural resources and reduce impacts on the environment.
The Environmental Management System certified at Eternit, Precon and SAMA ratifies the mitigation of significant environmental impacts on biodiversity (air emissions, wastewater and solid waste). The system establishes the guidelines for specific controls based on the standards and laws in each region. The Company did not register any incidents of violations of environmental laws and regulations in 2013.
At SAMA, the roads are constantly wetted for the traffic of machinery and trucks required for the mining activities. Mineral processing is conducted in a dry environment in which the equipment is enclosed with an efficient aspiration and air filtering system. Regular monitoring verifies the system’s efficiency. In addition, 100% of the work stations have a fiber concentrations of up to 0.1 fiber/cm3. Brazilian law establishes a limit of 2.0 fibers/cm3. In areas surroundings the operations, the concentration of chrysotile asbestos fibers is less than 0.003 fiber/cm3, with the level of quality assured by online monitoring of the air filter outlet.
In 2013, the number of samples taken increased 15.3% compared to 2012, and the result obtained in stations with a concentration of less than 0.1 fiber/cm3 improved from 93.0% to 94.7%. Environmental monitoring led to better concentration results in the year, with 100% of them under 0.002 fiber/cm3; in 2012, emissions below 0.002 fiber/cm3 amounted to 77.78%.
SAMA also monitors the vibration resulting from all blasts at the mine with three seismometers placed in pre-defined spots (in the mine, in the plant and in the city). With regard to vibration, in 2013 the number of samples increased 35.04% compared to 2012, and results improved: vibrations of less than 1 mm/s increased from 28.8% to 49.6%. With regard to noise, the number of samples taken increased by 38.8%, and the results also improved: noise levels of less than 110 dB went from 80.4% in 2012 to 85.6% in 2013.
At Tégula, the construction of storm drains and the lift-truck washing area was completed, as well as installation of the water and oil separation tank in the munck area. Measures taken to reduce impacts included replacing a diesel tractor with a gas one, renovating the cement dust removal system and adopting the concrete tile recovery through crushing. In 2014, the translucent tiles of the roofs of the plants will be replaced a measure that was initially expected for 2013.

Eternit monitors and encourages the preservation of biodiversity in environmental protection areas within or near its operating units. The total area of these protected habitats combined is equivalent to more than 4,000 football fields and harbors a wide range of species of Brazilian fauna and flora.
Because the preservation areas are isolated, the activities of the production facilities do not have a significant impact on local biodiversity. In addition, all environmental aspects and impacts are assessed based on the FMEA methodology, which ensures the mitigation of any environmental risks that could cross the border between the preservation area and operational areas. The Environmental Management System also ensures the mitigation of significant environmental impacts on biodiversity (air emissions, waste water and solid waste). In 2013, greenhouse gas (GHG) inventories were adopted as a measure to quantify the potential impacts on biodiversity. The Company’s only significant environmental impact on biodiversity is the emission of combustion gases from its lift-trucks and trucks operating inside the plant.
The activities inherent to mining operations may cause significant direct and indirect impacts on biodiversity, such as the suppression of vegetation to expand the pits, the loss and flight of fauna, as well as vibration, noise and emissions of particulate matter and gases. SAMA makes an effort to extract chrysotile mineral with the lowest possible impacts on the environment and conducts activities to recover degraded areas simultaneously to its mining operations.

Area description: SAMA’s concession area is formed by a total of 45 km2, but approximately 80% of this area is under its protection in the form of a preserved Forest Reserve and Legal Reserve that are located next to the remaining 20% of area, which is used for open-pit mining activities, such as mineral extraction, processing and overburden and waste disposal piles. The Forest Reserve is located in the Serra da Cana Brava mountain range, which features the typical cerrado biome and is part of the Alto Tocantins River Basin. A tropical wet climate predominates with two distinct seasons: a rainy summer season followed by a very dry winter.
In 2002, an environmental zoning project and a management plan began to be formulated with the goal of preserving the local fauna and flora. The many types of vegetation present in the Forest Reserve include: cerrado brush land, typical savanna, large savannas, seasonal forest, rupestrian fields and gallery forests. SAMA: Legal Reserve, 25 km2 of active reserve and 9.9 km² of legal reserve. The local biodiversity is protected by a native vegetation corridor that allows wildlife to move about without coming into contact with employees. The natural corridor bypasses the pits where mining activities are conducted with the constant traffic of trucks and auxiliary machinery.
The Chelonian Conservation Vivarium became the Scientific Wildlife Vivarium for conservation purposes, which is a protected habitat with total area of 29 km² located near SAMA’s Forest Reserve and Residential Village. The animals living in the area are classified based on IUCM 2003 criteria and the Endangered Species List of the Chico Mendes Institute (ICMBio):
1. Birds: macaws and parrots – not threatened; rheas – regionally threatened
2. Primates: capuchin monkey – critically endangered; marmosets – not threatened

Area description: the Tégula Atibaia Plant has built area of 15,074.87 m² on a property with total area of 112,738.24 m2. The total area includes the Environmental Protection Area (APP) measuring 4,881.05 m2. Approximately 20% of the APP harbors native vegetation species (goiabeira, jerivá, assa-peixe, fumo-bravo, tapiá, aroeira, pimenteira, sibipiruna, leiteiro, capororoca and ipê-amarelo) and is classified as Atlantic Forest, with fragments of broad-leaf forests and cerrado brush land. The APP is located at the coordinates GEO LATI 745035 and GEO LONG 328084 and is part of the Piracicaba, Capivari and Jundiaí River Basin, which is a name given under the definition established by Law 7,663/91, the State Water Resource Policy and the Integrated Water Resource Management System of the State of São Paulo, which is where the aforementioned rivers feed into the basin. The climate is temperate/dry with an average annual temperature of 19ºC and relative humidity of 80%. The APA, with a total of 4,881.05 m2, is located on the banks of Ribeirão Ponte Alta on the border between the companies Fundição Cruz Aço and Tégula. The area is formed by approximately 20% native vegetation and 80% low vegetation and grasslands.
In mining activities, the recovery of areas impacted by extraction is guaranteed by the Degraded Area Recovery Plan (PRAD). The purpose is to establish a mechanism for using the soil of degraded areas after the project is concluded to ensure the best possible condition for the environment and for integration with the local community.
In the case of the Cana Brava mine, SAMA’s Recovery Plan encompasses the entire area altered and those that could potentially suffer impacts from the activity. In its chrysotile asbestos mining activities, SAMA only removes soil from areas that already have already been authorized in advance by the environmental protection agency. The soil is used to cover the disposal piles in the final stage and part is reserved for future use. The blanketing of disposal piles with the soil and subsequent replanting of the vegetation aims to minimize the visual impact and protect them from the actions of water and wind.
The revegetation of areas adjacent to the mine has been carried out since 1986, and by 2013 nearly 15.28 hectares of degraded areas had been replanted. Some of the native species that have already adapted well to these areas are: Angico, Aroeira, Embaúba, Angico do Cerrado, Ipê and Periquiteira.
To improve the results and ensure the success of the revegetation process, the species planted are native to the region, such as Brachiaria humidicula, Brachiaria decumbens, Stylosantes guyanensis and Crotalarias pectabilis, among others. The recovered areas are systematically assessed based on their performance in vegetation protection and water conditions. If any evidence of erosion emerges, SAMA makes corrections. Over the last 3 years, 31.8 hectares of area were recovered, which included overburden, waste and soil piles. Every year, not only are the areas recovered in the previous year inspected, but all the recovered areas are monitored to ensure that actions are taken in the event of instability or erosion. SAMA’s Scientific Wildlife Vivarium has a total area of 29 km2 and is home to macaws, parrots, rheas, various monkey and turtle species as well as
other wildlife.
Two of SAMA’s actions focus on preserving and conserving the natural environment. The Water Conservation Environmental Awareness Project raises awareness among the community on the importance of using water resources wisely. The actions, which also mobilize employees and local schools, are intensified during the dry season to prevent waste. The company also works to preventing wildfires in the Forest Reserve by supporting its Fire Brigade through the Program to Combat Burning Practices.
Reduce, Reuse and Recycle: the 3Rs principles resonate in every activity performed by the Group supported by its zero waste policy. Materials that are broken or fail to comply with standards are crushed and reused to make fiber-cement, which also includes pulp originating from paper used in the administrative areas and in the chrysotile packaging, which is 100% reused.
At Tégula, the plant in Içara (Santa Catarina state) controls the recovery of the wood slats used in the loading process: in 2013, 3,050 slats were recovered, which is equivalent to R$518.50. In Atibaia, the wood slats were removed from the pallets used for roofing tiles, with the wood frames used only for tiles in the ivory and prime lines. The concept is currently being implemented at the other units. At Tégula Plant in São José do Rio Preto, 1,445 wood frames were recovered, which generated savings of approximately R$2,500.00.
SAMA does not use recycled materials in its production process, but the pallets are renovated, while cast pallets undergo reverse logistics, with both reused, which reduces costs. In 2013, this measure represented 0.35%; the reduction target for cast pallets in 2014 is 1%. The mining company also uses the remaining parts of production lots that did not complete a pallet to form new batches, with a total of 1,258 metric tons of mineral reused, which represents savings of 25,160 raffia sacks, or 0.43% of the total product sold.
The reuse of pallets and the use of recycled pulp guarantee that 0.15% of inputs in the production process come from recycled materials. Since 2006, other recyclable materials have been collected under the Reciclanit Program and sent to recycling cooperatives and companies.
Proper destination of solid The wood chocks from the packaging of all finished products shipped from the plants of Eternit and Precon can be recovered. Some of the wood chocks and slats are reused in the packaging for stocking and selling bathroom chinaware, polyethylene water tanks and covers as well as other products.
The small amount of waste that remains includes oil sludge, felts, hoses, tires and scrap metal, which are properly disposed of by specialized companies. At SAMA, the overburden is deposited on banks for subsequent recovery and replanting of the vegetation. Only a small fraction of the material is used by the Sambaíba Project to produce handicrafts.
In 2013, SAMA recorded 2 oil spills in an estimated aggregate amount of 290 liters. The incidents occurred within the mine area near the primary breaker. The oil that spilled into the soil was covered with sawdust, collected, stored in drums and sent for co-processing. The site is not located close to bodies of water and there was no percolation due to the immediate measures taken.

The measures adopted by Eternit in 2013 to reduce energy consumption include using LED light bulbs, adapting its electrical installations and installing translucent roofing tiles. At its plants, the replacement of old, oversized engines with more efficient ones also led to the more efficient use of natural resources. The Company did not register any reduction in its energy consumption in 2013 due to the growth in its production, which resulted in a 10% increase in its raw material use compared to 2012, and consequently increased its consumption by approximately 16%.
SAMA started implementingThe Eternit Colombo plant has a firewood boiler to generate energy for the production process. Most of the fuel used comes from wood packaging waste and from the wall cladding panel production process.
In 2013, SAMA started implementing the Energy Management System ISO 50001 to support the more efficient use of its main energy matrixes (electricity, diesel and LPG). It also continued to carry out automation projects on the lighting of its conveyor belts with the expectation of reducing its power consumption at these sites by 90%, and completed installing the new capacitor bank to increase the power factor and reduce losses. The mining unit is analyzing the use of LED lighting and the installation of small solar power plants to supply electricity to specific areas of the company. Energy consumption increased between October and November due to the higher volume of water pumped from the pits in the mining area.

The Company monitors greenhouse gas (GHG) emissions at its units and in the mining operation using processes aligned with the Environmental Management System, which facilitates data integration and enables comparisons with data from previous years.
At SAMA, since October 2010, the fuel used in the 5 mineral drying furnaces is liquefied petroleum gas (LPG), with average monthly consumption of 304,493 kg. In addition to its market advantages, such as easy handling, transportation and storage, fast combustion and high caloric value, LPG also offers environmental benefits, since it does not produce toxic waste and generates low emissions of carbon monoxide, nitrogen oxides and particulate matter. The monitoring of the furnace stack outlets indicates emissions below the limits established by law.
At SAMA, black smoke emissions are measured based on the colorimetric scale (Ringelmann Method). In 2013, 1,464 measurements were carried out, of which 1,294 met standard 1 and 170 met standard 2 on the scale (maximum is standard 2). With regard to environmental noise, 306 measurements were conducted at 17 spots in surrounding areas and all of the results indicated values that meet the legal standard.
At Eternit and Precon, the videoconference system was adopted to reduce the need to travel.
Another initiative adopted in the year was the monitoring of GHG emissions from the diesel vehicles in our fleet operating in the Tégula Atibaia Plant. The plant also has solar energy panels to reduce the burning of fuel for the water heaters used in the curing chambers of the Atibaia 2 Plant. At Tégula Içara Plant in Santa Catarina, wind-powered exhaust fans provide employees with greater thermal comfort and improve the work environment.

With the acquisition of new equipment, interventions in the air-conditioning system decreased, since this gas is only used when the internal part of the system is cleaned due to contamination or replacement of components.
The Eternit, Precon Goiás and Tégula units do not use any ozone-depleting substances or substances covered by Attachments A, B, C and E of the Montreal Protocol.
The Eternit, Precon and SAMA units also monitor and control suspended fibers.
| Eternit and Precon | |
|---|---|
| Controls | Bagfilter – all stacks and exhaust fans have a bagfilter system to filter any potential particulate matter (only emissions from dust removal systems). Classification of particulates: NOx and SOx – Periodic monitoring of emissions through a report issued by an outsourced company. |
| Suspended fibers | On a weekly basis, measurements are conducted at various points of the plants to measure the number of fibers/cm³ of air. In accordance with regulations, the Company undertakes to maintain a maximum concentration of 0.10 fiber/cm³ of chrysotile mineral in all workplaces. The outsourced report was issued by Projecontrol. |
| Results | In 2013, 100% of the work stations (150 measurement points) had results of less than 0.10 fiber/cm³. |
| SAMA | |
| Controls | Bagfilter – all stacks, vacuum cleaners and sweeping machines have bagfilter and cartridge filter systems to filter total particulates. In addition to the monitoring, there is one employee per shift responsible for the daily inspection of bagfilter and filters. |
| Suspended fibers | On a monthly, quarterly or semiannual basis, various points of the company and surrounding areas are monitored to measure the number of fibers/cm³ of air. For inorganic fibers (occupational sampling), the limit established by the National Agreement for the Safe Use of Chrysotile is 0.10 fiber/cm³. |
| Results | In the year, 100% of the work posts (90 measurement points) had average results below the limit, which is 2.0 fibers/cm³ according to NR-15, Attachment 12. |
| Notes | LPG gas is currently used in the mineral drying furnaces, since it is a clean source of energy. NOx, SOx, MP and CO measurements are conducted and the results are satisfactory in comparison with various legislations, since there are no specific parameters for LPG. |
Water consumption in the Eternit Group’s operations does not significantly affect local ecosystems. There is no disposal of water originating from production at the Eternit and Precon plants: the water resulting from the production process is stored in decantation tanks and later used in a closed recycling circuit. As a result, water loss occurs only through evaporation. The water used in administrative buildings goes through the Wastewater Treatment Station (ETE) and is reused to irrigate green areas. A few units have also implemented rainwater harvesting initiatives. All Tégula plants reused the water that was used to wash the varnish machine in 2013.
After biological treatment, SAMA’s wastewater is routed to the stabilization pond before being disposed of in the Amianto Stream, which is subject to periodical chemical analyses. Water from the pits, which must be emptied for the exploration process to continue, is sent to Lagoa das Tartarugas and Lagoa do Jacaré (both decantation ponds) and then to water bodies (Lagoa do Caju Pond and Amianto Stream) or used to wet roads, industrial waste and fronts to be disassembled to avoid the release of dust.
In 2013, SAMA reused 14,356.40 m3 of water, nearly 2% more than the 14,086 m3 reused in 2012. This water is pumped from the decantation tank located behind the maintenance workshop and the stabilization pond of the wastewater treatment station during the industrial waste wetting process. The volume represents nearly 1.13% of the total water used by the company.
