Our approach to sustainable development is to set out an overall framework but to give our operations the flexibility to implement programmes that best meet their local circumstances.
View the case studies below to see how we implement our 10 sustainable priorities locally.
Improving energy efficiency at Birra Peroni
Since 1999, Birra Peroni has more than halved its energy consumption and now uses 110 MJ per hectolitre of beer produced.
Much of this saving has come from capital investment such as installing a new brewhouse and pasteuriser line, improving the wastewater treatment plant and increasing the recovery of biogas.
We are now working with engineering consultants Danfoss to raise awareness and improve energy efficiency through small-scale interventions. Danfoss has audited our plants, processes and systems. Having identified further potential savings, collated baseline data and finalised the costs, we are now working to implement these improvements.
Dreher - our latest plant to use biogas
In January 2008, Dreher in Hungary became one of the growing number of breweries in the group to introduce a wastewater treatment and biogas generation plant.
Biogas is a by-product of anaerobic wastewater treatment and can be burned to produce energy.
Energy produced from burning the biogas should allow Dreher to reduce its traditional annual energy consumption and the related carbon dioxide emissions by 10%. It also leads to a reduction in the amount of organic matter released to the environment.
Alternative energy in India
Despite the growth of India’s manufacturing and services sectors, agriculture still makes up 20% of the economy and supports 75% of the population.
During the expansion of its Rochees Brewery, our Indian business took the opportunity to install its first solid fire boiler, rather than the more typical option of heavy fuel oil or methane. The aim was to reduce thermal energy demand by 42%.
It also allowed the company to move to a renewable, more environmentally friendly source of energy – rice husks. This is expected to save some 4,000 tonnes of carbon dioxide per year and also to provide local farmers with an income for their agricultural waste.
The project has been a success – the business is well on track to meeting and then beating its energy consumption target. It intends to use the same technology in a new plant in Haryana and the expansion of a brewery in Charminar.
