Conscientious use of resources

The guidelines of Odebrecht’s Sustainability Policy include the themes of rational consumption of resources and proper waste management. Each Business establishes the indicators for monitoring and specific targets for performance in keeping with the materials it uses, as shown in the following table.

ESSENTIAL RESOURCES IN THE PRODUCTION PROCESS

Resources Businesses in which use is significant Reason for significance
MATERIALS Environmental Chemicals used in the process of treating water and sewage
Braskem (petrochemicals) Derived from petroleum, the main input, naphtha, is non-renewable. Raw materials are renewable when they originate from ethanol (Green Plastic)
Construtora Norberto Odebrecht/Engineering & Construction International Large amounts of materials used, which involves mineral extraction (steel, cement) and non-renewable fuels
Agroindustrial (sugar, ethanol and biomass energy) Agricultural and industrial inputs used to mill sugarcane
 WATER Environmental Treatment and distribution of water is the company’s business
Braskem Amounts used in industrial processes
Agroindustrial Amounts used in agricultural and industrial processes
Construtora Norberto Odebrecht/Engineering & Construction International Amounts used in production processes
ENERGY Environmental Amounts consumed in water treatment and distribution and waste treatment
Braskem Amounts used in production processes
Construtora Norberto Odebrecht/Engineering & Construction International Amounts used in production processes
Agroindustrial Generates energy and is self-sufficient in this regard

Materials

The Materials aspect is more significant for the operations of Construtora Norberto Odebrecht, Braskem, Odebrecht Agroindustrial and Odebrecht Environmental due to the quantities used in their production processes. The management of the issue is decentralized, and the Holding Company is responsible for monitoring the indicators.

Odebrecht Agroindustrial’s main inputs are water, agricultural products (fertilizers, correctives, herbicides), industrial products (sulfuric acid, lime, soda), fuels and electricity. The main raw material is sugarcane. During the 2015-2016 harvest, there was an increase in the amount of materials consumed due to higher production and, consequently, the amounts of processed sugarcane. In addition, the Business introduced more stringent controls of the uses and indication of quantities used in relation to the past. Its Units have been significantly improving their production, process quality and techniques, seeking to extract the maximum from the sugarcane plantations, which is reflected in the increase in processed cane and higher production. Other materials, such as herbicides and insecticides, showed an increase in consumption, mainly explained by improvements in the cane fields and pest outbreaks, such as the spittlebug.

Within Construtora Norberto Odebrecht, the consumption and disposal of materials is managed individually at each construction site, where the most appropriate solution is utilized. One example is the use of the Bubbledeck system, a technology that reduces the volume of concrete used in structural slabs by 35% without impairing the functions and performance for which it was designed. In addition to minimizing the production of solid waste, this solution reduces the consumption of water, wood, steel and cement, also minimizing greenhouse gas emissions.

In 2015, Construtora Norberto Odebrecht used 15,182 cubic meters of recycled wood, equivalent to 12% of the total amount of that input consumed in the year. G4-EN2Click for more information on this aspect in the GRI Content Index

Pioneering use of Bubbledeck

This technology was first used in Brazil in the construction of Odebrecht’s offices in Salvador, Bahia. After that, Braskem and Bubbledeck formed a partnership that made it possible to supply plastic resins to produce plastic balls in Brazil with support for the adaptation of the technology to the Brazilian market. Construtora Norberto Odebrecht has replicated that innovation on two more projects- the Federal District Administrative Center and Antonio Carlos Jobim International Airport in Rio de Janeiro.

The Bubbledeck technology was used in slabs for the Federal District Administrative Center in Brasilia

2 - Materials renewed by ecological cycles or farming processes, such as wood, ethanol and vegetable oil

The basic inputs used by Braskem are non-renewable direct materials, such as naphtha, condensate, ethane, propane, HLR and sodium chloride. The company also uses ethane manufactured from sugarcane ethanol to produce ethylene from renewable sources, thereby reducing its demand for fossil fuels. The amounts and/or weights consumed are not disclosed because they are commercially sensitive information. In its industrial units, the company maximizes the reuse of raw materials, or internal recycling. Looking to the future, investments are being made in chemical recycling and energy recovery.

Energy G4-DMAClick for more information on this aspect in the GRI Content Index

Due to the quantities used in their operations, the Energy aspect is more significant for the petrochemicals (Braskem) and construction (Construtora Norberto Odebrecht and Odebrecht Engineering & Construction International) Businesses. It is also important in Agroindustrial, as the company is self-sufficient and generates energy for sale as part of its consolidated production model for sugar, ethanol and cogeneration of renewable electric energy from sugarcane bagasse.

During the 2015-2016 harvest, Odebrecht Agroindustrial’s surplus generation totaled 2,200 GWh, enough to supply more than 10 million people. Improvements such as greater use of steam and optimization of cooling towers have favored the energy balance of industrial units at each harvest. During that period, 99.5% of electric power consumed was supplied by energy generated from sugarcane bagasse.

At Construtora Norberto Odebrecht, priorities for optimizing the consumption of energy resources vary according to the types and phases of its projects. Each construction site is responsible for energy management, but a comparative evaluation of the results makes it possible to identify best practices for common use. The recent reduction in energy consumption reflects the smaller number of projects in 2015.

Reusing water at Unib 1, Braskem’s main industrial plant at the Camaçari Complex

Water G4-DMAClick for more information on this aspect in the GRI Content Index

Efficiency and conscientious water consumption are an integral part of the operations of all Odebrecht Businesses. However, the initiatives of Odebrecht Environmental, Odebrecht Agroindustrial and Braskem are among the highlights.

At Odebrecht Environmental’s units, attention is focused on reducing losses and internal consumption by optimizing production processes and improving the distribution network. The company is the largest private provider of water and sewage treatment in Brazil, serving approximately 17 million people in 179 municipalities. In addition, it is a pioneer in the supply of recycled water for industrial use, serving major Clients in sectors such as steel, petroleum, petrochemical and pulp & paper. As a result, it helps in the management of those companies’ environmental issues, employing sustainable methods and technologies in water and effluent treatment and reuse, and environmental monitoring. Of the total water consumed in 2015, 37.9% came from recycling and reuse. That figure includes the number of Client-Users (individuals and industries) and internal use (all water used in the processes of treatment of water, sewage, waste area and Utilities).

In the Group’s agroindustrial operations, water is an essential productive input and its consumption in sugarcane milling is monitored by an eco-indicator published weekly. Adaptations and increase of efficiency in the process in the 2015-2016 harvest reduced the total amount of the indicator of 1.13 m3 per ton of cane reached in the previous harvest by 11.5%. Reuse through the recycling of water in the industrial process corresponded to 43.9% of the total captured.

Braskem consumed 4.05m3 of water per ton produced was consumed in 2015, which was a 1.6% improvement over the stipulated target for the year (4.11m3/t). In absolute terms, Braskem consumed 66.2 million m3 of water in 2015, representing a reduction of 0.7% compared to 2014. (More information can be found in the company’s annual report, accessible at www.braskem.com.br.)
