Water footprint of Elovena
Elovena's water footprint covers the journey of oat from the field through production to the shop warehouse. From there forward, a consumer's daily water choices essentially affect the water footprint.
Total water consumption of Elovena Oat Flakes is 101 litres per hundred grams of product. Total water consumption includes the water used by plants for growth and to manufacture the product as well as wastewater.
The water footprint of oat indicates, among other things, how much water a plant uses during the growth. Part of this water remains in the grain. Most of the water consumption is water that oat uses during the growth and gets as rainwater through the natural cycle. Oat grown in Finland is not irrigated so it does not compete with clean drinking water. All Elovena products are made of Finnish oat.
Water consumption of Elovena Oat Flakes
- Cultivation 99.3% (rain water)
- Processing 0.57%
- Packaging materials 0.16%
The production and packaging materials of oat flakes jointly account for well under one per cent of the overall water consumption. The flake production uses water in the form of steam. This is why the process produces very little wastewater.
Calculation method of a water footprint
In terms of primary production, the calculations are based on the evaporation data obtained from the Finnish Meteorological Institute's weather observation stations, the water used in oat cultivation and three-year averages for oat crops supplied by Raisio's contract farmers. Water consumption of oat flake production is known precisely. Water footprint calculation for packing materials, energy production and transports is based on the consumption of goods.
