Dairy processes consume energy in the form of steam and electricity. The latter is mainly required in process equipment use and cooling.
Energy consumption and related emissions
Large amounts of thermal energy are required in drying powder products, the heat treatment of some products, for cleaning, and in heating buildings. The boiler rooms at Valio plants are primarily maintained by subcontractors. Valio will no longer be using heavy fuel oil in heating any of its 13 production plants operating in Finland by 2017. The last boiler plants to be converted are in Oulu (to go online in 2016) and Jyväskylä (2017).
The share of renewable fuels in thermal energy production was 36% in 2015 and that of Finnish fuels 69%.
Energy production results in emissions into air. The quality and quantity of emissions depends on the fuel used in that energy production. Valio’s Lapinlahti and Seinäjoki boiler plants are included in the emissions trading system under the Kyoto Protocol.
Valio’s environmental system
Valio has held an ISO 14001 environmental certificate covering its domestic operations since the year 2000. The certificate was re-approved in 2015 to be in force until 29 September 2016.
Environmental system performance undergoes continuous evaluation via internal and external audits
Valio’s environmental goals are determined in three-year programs, and annual intermediate goals are set on the basis of the specific measures to be taken. The three-year programs provide the opportunity to create proper focal areas, and also enable measures for more controlled planning, implementation and efficiency
