Volume of waste water decreased
|Valio used 4.1 million cubic metres of surface water from the water system for process flow cooling in 2009. The company also consumed 4.9 million cubic metres of household water: 4.5 million from municipal waterworks and 0.3 million from its own supply. The consumption of reused water totalled 1.0 million cubic metres in 2009.|
The consumption of clean household water increased by 0.7% on the previous year. In 2009, Valio production plants discharged 5.0 million cubic metres of waste water, 2.4% less than in the previous year.
|Nordic Jam incorporated into the figures|
|The chemical oxygen demand (COD) describing the amount of organic substances in waste water (10,158 tonnes) was 1.5% up on the previous year.|
The increase in water consumption and the waste water load was occasioned by the merger of Nordic Jam Ltd into Valio Ltd as of the beginning of 2009.
Cooling and condensation waters were discharged directly to natural waterways. Three plants hold a permit from the water rights court to discharge waters, and one has an environmental permit that includes the option to do so. Obligatory monitoring related to the permits observed no harmful impacts from the discharges in 2009.
