Committed to reducing GHG emissions, Bunge produces most of the electricity it consumes, producing bioelectricity from sugarcane bagasse burning.
With the target of reducing greenhouse gas (GHG) emissions, Bunge Brasil invests in reducing energy consumption at its manufacturing plants, as well as in adopting a renewable energy matrix. In 2015, the company's energy matrix consisted of 94% renewable fuels.
Energy consumption is directly related to climate change, to the exhaustion of natural resources (fossil fuels) and atmospheric pollution. Consequently, careful management of energy consumption is essential in our operations.
The major part of direct energy consumption occurs in the following processes:
Each plant manages its performance focused on the following targets:
In 2015, the Sugar & Bioenergy area exported 570,043 MWh to the Brazilian national grid (SIN), 8.03% more than in the previous year. This is enough energy to meet the annual power needs of approximately 300,000 households. Cane-powered bioelectricity helps reduce GHG emissions through replacing other fossil-based energy sources, as well as representing a sustainable alternative for producing the energy required in production activities in the country.
In 2014, the company assumed a commitment to reduce energy consumption per metric ton produced, in addition to its CO2 emission reduction targets. The target is a 3% reduction in energy consumption from 2013 to 2016.
Compared with 2014, there was a 4.76% reduction in the indirect energy used in production processes, from 0.063 to 0.060 GJ/t produced. This decrease was enabled by the continuous implementation of operational efficiency improvement initiatives in company units. The reduction in direct energy consumption is mainly due to improved efficiency in burning bagasse and in generating electricity in the Sugar & Bioenergy mills.
Energy self-sufficiency
Bunge produces the equivalent of 100% of the energy it consumes in its manufacturing processes. This is because the company's Sugar & Bionergy area mills are equipped to produce clean, renewable energy based on burning sugarcane bagasse. With an installed capacity of 317 MW, in 2015 the eight mills generated 985 GWh (1.8% more than in 2014), supplying 100% of the energy needs for the company's production processes during the year. Of our eight mills, six are prepared to export renewable energy to the national grid (SIN). The volume exported corresponded to the 58% of the energy Bunge produced in the year – 7.8% up on 2014. Over the last three years, the generation capacity of the Pedro Afonso and Moema mills has increased gradually.
Located in the São Paulo district of Jaguaré, this Foods & Ingredients unit completely refurbished its industrial refrigeration system used in the margarine and shortenings crystallization process and in the refrigerated warehouses.
The old system, which used twelve compressors and was 100% manual, had been in operation for more than 40 years. The technology was obsolete, and energy efficiency was low.
Implanted in 2015, the new system is fully automated and employs only four compressors. Operation is modulated, meaning the compressors supply the precise amount of energy required by the production process at any given moment. This ensures great energy efficiency, driving projected savings of more than 2,300MWh/year in energy consumption. The condensers were also upgraded, ensuring heightened efficiency in water consumption, with savings projected at over 10,000 m³/year.
Another significant gain with the new system is safety: with a 40% reduction in ammonia content and a totally automated system, the risk of leaks and exposure for employees and the surrounding community has been reduced significantly.

Emissions drop 7.87%
In 2015, Bunge Brasil's overall emissions rate dropped by 7.87% compared with 2014. This reduction was due to a decrease in the volume of sugarcane bagasse used as fuel in the company's boilers. In spite of the reduction in burning, the volume of energy generated was higher than in 2014, proof of greater efficiency in the bagasse burning process.
