To optimize energy intensity in industrial, commercial, logistics and administrative operations, by promoting a culture of efficient use of this resource and migration to cleaner sources of energy.
|Reduce energy intensity in operations.||
A cumulative reduction of 17.7% was obtained in total energy consumption for the period 2010–2015. G4-EN6
Energy consumption per ton produced increased 0,6%over 2014, due to the low availability of natural gas supply for the industrial sector in Colombia, which led the Organization towards the use of fuels such as diesel, crude oil and coal.
|Reduce the electric energy in operations.||
Electricity consumption (kWh/t.p.) decreased 1.7% over 2014. The cumulative reduction since 2010was 9.3% for the plants in Colombia. G4-EN6
|Reduce the thermal energy of non–renewable sources in operations.||
The indicator of thermal energy consumption from non–renewable sources (fossil fuels) (kWh/t.p.) increased 1.8%% over 2014 in the plants in Colombia.
For the period 2010–2015, the reduction in the thermal energy indicator was 21.3%.
|Increase the use of renewable sources of energy.||
Energy generation from the use of biomass represents 13.6% of the total energy basket for operations in Colombia and 45.2% for operations in Chile.
Three pilot projects for auto–generation with solar plants in the Coffee and Chocolate Business plants in Colombia and in ice cream points of sale in Costa Rica were begun.
Grupo Nutresa may be exposed to financial and reputational risks arising from the variability of world prices for fossil fuels, the possible conditions of temporary or permanent shortages of some of them, climatic events that temporarily put the safety of hydroelectric energy supply at risk and the growing trend and interest of different audiences for the use of cleaner energy and renewable energy.
Aware of these challenges, the Organization focuses on searching for greater energy efficiency in its direct and indirect operations, using cleaner fuels, energy sources with less environmental impact and incorporating new technologies to reduce Greenhouse Gas (GHG) emissions.
The response to energy challenges is supported by establishing challenging goals for 2020, such as reducing energy consumption per ton produced by 25% and having 100% of the energy supply from energy classified as cleaner.
The Grupo Nutresa businesses have established plans to reduce energy consumption in their processes through technological transformation projects, equipment upgrades, and energy audits that reduce dependence on thermal energy from non–renewable sources (natural gas and other fossil fuels), and increase the participation of alternative energies (biomass, thermal solar energy and solar photovoltaic energy) to eventually reduce GHG emissions by 2020.
Similarly, we will continue to promote the implementation of the principles of energy efficiency in logistics processes, the incorporation of low–energy consumption technologies in new distribution centers, the exploration of transportation projects through a fleet of more efficient vehicles and/or vehicles fed with cleaner energies, driver training and promoting different alternatives of sustainable mobility among employees.
A success story to highlight is the reduction in baking times of the Panettones in the Chocolates Peru factory, from 75 to 60 minutes, thanks to adjustments in regulating and monitoring oven temperature, ensuring that the characteristics of the project are not altered by the impact of changes. Making the comparison between the 2014 and 2015 season, the same production of panettone was achieved, but the operation was reduced in eight days, equivalent to a saving of 7,664 m3 of natural gas.
Other success stories was the installation of high–efficiency engines in the Coffee plant in Santa Marta enabled savings of 336,504 kWh in electricity, which represents 17.4% of total consumption in the plant in a year.
Also noteworthy is the independent cooling systems for cold rooms in the Ice Cream Business plant in Bogotá, which works with the evaporation temperature required in the rooms, separating the temperatures required in the production process and those to store the product, thus achieving efficient energy use. This project generated savings of COP 120 million a year and reduced the energy intensity by 17 kWh per ton produced.
In Grupo Nutresa, energy use is considered an important variable in the competitiveness of the businesses and is critical to the environmental impact of operations. Therefore, it focuses on optimizing energy consumption and shifting to renewable sources.
In 2015, a complete internal energy–efficiency diagnosis was carried out in the production plants in Colombia. Each business identified those projects that contribute to productivity, reduce consumption of fossil fuels and contribute significantly to achieving the objectives proposed for 2020. A work plan was established to implement the projects that have the best reduced cost per kWh and the contribution to the fulfillment of the goal. For the 2016 investment plan, 16 projects were prioritized, focused on improving energy efficiency in all the businesses.
In international operations, the lifting of key environmental indicators and establishing plans to save and efficiently use energy began. Data from the Ice Cream Business operations in Costa Rica and Dominican Republic, Alimentos Cárnicos in Panama, the Biscuit plants in Costa Rica and the United States, the Chocolate plants in Costa Rica, Mexico and Peru, and the Tresmontes Lucchetti plants in Chile are reported.
During 2015, weather conditions in Colombia due to the El Niño Southern Oscillation (ENSO phenomenon) affected the supply of natural gas in some production plants and it was necessary to use other fuels (LPG, crude oil, diesel, coal) to ensure the continuity of the businesses.
For this reason, energy intensity (from non–renewable thermal and electric sources) per ton produced in Colombia presented an increase of 0.61% over 2015, although a cumulative reduction of 17,7% is maintained for the period 2010–2015 in relation to the goal of a 25% reduction by 2020.
This situation caused a 1.81% increase in the consumption indicator of thermal energy from non–renewable sources (fossil fuels) compared to 2014, causing fuels – such as diesel, crude oil and coal – to present an increase of 127.3% over the year before.
The indicator of energy consumption (kWh/t.p.) had a 1.7% reduction over 2014; for the period 2010–2015, the cumulative reduction was 9.3%, thanks to the implementation of technological conversion projects developed in all the businesses and supported in the rationalization of consumption.
The plants continue to implement best operational practices and projects to improve energy efficiency, such as programming production processes (coordination between the Service and Production Areas), the installation of variable frequency drives in pumping and ventilation systems, the implementation of control devices in lighting, more efficient lighting systems with the combination of LED technology, inductive lighting, translucent tiles and intelligent control.
Electric energy from the Colombian national grid increased by 1,450 MWh, which means an increase of 0.9% over the 2014 net consumption.
As for thermal energy from non–renewable sources, Grupo Nutresa advanced in conversion processes and technological upgradings, process standardization, burner calibration and fuel switching, which together constitute a set of best practices adopted and shared by all the plants. This reduced the thermal energy consumption indicator (kWh/t.p.) by 21.3% for the 2010–2015 period.
Thermal energy from non–renewable sources increased by 14,000 MWh, which means a 4.6% increase over the net 2014 consumption.
Grupo Nutresa has an energy basket in which the use of cleaner fuels – such as electricity and natural gas – is dominant. The intensive use of biomass in the Coffee and Tresmontes Lucchetti businesses is maintained and pilot projects have been developed to use thermal solar and photovoltaic energy, in the search for cleaner alternatives to replace sources with greater environmental impact.
In industrial facilities in Colombia, 97.9% of the energy consumed comes from cleaner sources, such as natural gas, biomass, solar energy and electricity. The use of biomass represents 18.3% of the energy of the Group in Mexico, Costa Rica, Colombia, Peru and Chile.
Despite efforts to use new energy sources, the weather situation affected the availability of cleaner fuels in some areas of Colombia; to offset cuts in the supply of natural gas, fuels such as LPG, crude oil, diesel and coal increased from 0.9% to 2.1% in the energy basket.
In the search for alternative energy sources, the Chocolates plant in Costa Rica will install a biomass boiler.
