Develop products and processes as energetically efficient as possible along the whole supply chain, reducing, where opportunity arises, thedependence on fossil fuels such as oil and coal.
Our commitment is to develop products and processes along the entire supply chain that are as efficient as possible in terms of energy use, reducing, where the opportunity arises, the use of fossil fuels such as oil and coal. Numerous projects have been developed over the years with this aim in mind, in particular the Energy Saving Project, the progressive reduction of fossil fuels used in Sweden and the construction of cogeneration plants.
BARILLA ENERGY SAVING PROJECT (ESP)
This is a project developed in the Italian bakeries to improve plant management efficiency in the factories of the bakery business. The Energy Saving Project gave rise to a decrease in the consumption of electricity and thermal energy of 9% and 3% respectively over a two-year period.
The ESP project resulted in the following work:
• installation of variable speed air compressors;
• installation of high performance water type condenser refrigerator groups;
• installation of boiler and oven fumes heat recyclers;
• high performance electrical engines;
• installation of inverter pumps and ventilators;
• energy saving light bulbs fitted.
PROGRESSIVE REDUCTION OF FOSSIL FUELS IN SWEDEN
The progressive reduction in the use of fossil fuels in the Filipstad factory in Sweden has led
to a 65% fall in consumption per unit of finished product and a significantly higher fall in CO²
emissions by the factory.
COGENERATION PLANTS
The cogeneration plant for the combined production of heat and power became operative in Pedrignano (PR) at the end of 2008. The plant uses methane gas to produce heat and power that are fully reused in the production cycle. This results in a significant reduction in the emissions of CO² equivalent.Furthermore, construction of a trigeneration plant (producing power, heat and cooling) commenced at the Caserta facilities in 2008.
ENERGY CONSUMPTION TRENDS
These projects have resulted in a decrease in the energy consumption of the bakeries and
pasta factories. The graph shows the energy consumption (electrical power and natural gas) of our factories throughout the world in the three-year period 2006-2008.
Production increased by 4% while energy consumption remained constant allowing a 5% fall in energy consumption for each ton of finished product. We have achieved decoupling between the growth in volumes and energy consumption.
Lower energy consumption also contributes to decreased emissions of carbon dioxide, one of the main gases that cause the greenhouse effect.
GLOBAL WARMING POTENTIAL (GWP) OF ENERGY SUPPLY CHAIN
Global Warming Potential - GWP is the indicator used to express CO² emissions. GWP is measured by mass of CO² equivalent, converting the emissions of various gases to CO² emissions based on factors fixed by the IPCC (Intergovernmental Panel on Climate Change).
The GWP used calculates the emissions of CO² equivalent generated by the entire energy
chain, from the extraction of the fuels and their transport, through to direct use or use in
the production of electrical energy.
This indicator differs from that normally used in the Emissions Trading calculations that consider only CO² emissions and not CO² equivalent generated directly by production plants and power plants. The purpose of this indicator is to allow Barilla to make the best choices when acquiring energy from producers that employ technology with the lowest environmental impact.
CO² EMISSIONS
The graph shows carbon dioxide emissions of the Barilla factories throughout the world measured in GWP for the three-year period 2006-2008. A decoupling effect has also been achieved here between the growth in volumes and CO² equivalent emissions.Production increased by 4% while emissions increased by only 2%.
REDUCTION OF ENERGY CONSUMPTION
The aim to decrease energy consumption over the next five years will be achieved through
the following:
• development and expansion of the Energy Saving Project to all Group factories;
• full operation of cogeneration plants and installation in other factories.
As the energy mix has a significant influence on carbon dioxide emissions, in addition to the
above initiatives Barilla has decided to consider using energy that reduces the dependence on fossil fuels; in particular all electrical energy required in future for the production of Mulino Bianco products will possess special certificates (RECS) certifying that they are generated from renewable sources.
The coefficients used to determine CO² equivalent emissions associated with electrical energy consumption, were calculated using the Ecoinvent database and reports of the International Energy Agency (IEA). Ecoinvent issues emissions data for each technology used in electrical conversion for a number of countries, while the IEA provide information on the energy mix represented by an analysis of the different technologies used by country. The Ecoinvent data relate to energy production for 2004 and the IEA data to production in 2008. The conversion coefficients used for the calculation were defined by the Intergovernmental Panel on Climate Change (IPCC) in 2007 (source PAS 2050).
The RECS (Renewable Energy Certificate System) is an international instrument created
to stimulate the use of renewable energy. A certificate is issued for each MWh of electrical energy produced from renewable sources. In acquiring these certificates companies may certify that the energy used derives from renewable sources. For further details please visit:
