Kellogg - Case study: Cutting CO2 emissions
By the end of 2008, Kellogg's was tracking at about 25% less energy used per tonne of food produced against
the
1990 baseline.
In the last three years, Kellogg's UK cereal operations have
reduced their energy production by 3.7% per tonne of food and this has led to
an
emissions reduction of 4% per tonne over the three years.
Much of the progress can be put down to good
housekeeping. For instance, the company is replacing the
30,000 lights used in its Manchester site with tubes that
are up to 60% more efficient and it has installed 86 new
meters to accurately monitor its use of electricity, gas and
steam and thus identify inefficiencies.
However, the biggest single factor in Kellogg's ability to
reduce energy usage and emissions was the installation of
a Combined Heat and Power plant in 2007.
This provides the Manchester site with 80% of its steam
and 40% of its electricity requirements. This CHP plant
has reduced the amount of energy the company needs to
take from the national grid, and has meant a reduction in
indirect emissions, energy and costs.
In its Wrexham site, Kellogg's has taken the same
approach – focusing on measuring and managing – and
has developed an on-line energy monitoring tool to help in
that task. It is also steadily replacing older equipment with
more efficient models.
