Recycling water & waste water 64% of total water demand reused

Water consumption reduced by almost half

EVVA headquarters is located in a water protection area, which is why sustainable use of this resource is important to us. EVVA does not recirculate water, but consumes it itself. We need water for production processes that have not yet been converted to Clean Production, i.e. currently for 30% of production facilities, as well as for electroplating and for personal hygiene. EVVA aims to continuously reduce water consumption at its headquarters in order to conserve this resource to the greatest possible extent. In 2010, EVVA still consumed 7,153 m³ of water, in 2019 only 4,031 m³. In 2020, consumption fell further to 3,709 m³ (2,351 m³ for electroplating, 1,358 m³ for body care and other). So within 10 years a reduction by almost half.

Lower fresh water consumption

Reasons for water savings:

  • Photo of a vacuum evaporator

    EVVA is increasingly using Clean Production machines that do not require water 

  • more effective production and water treatment processes in electroplating (for the surface treatment of our products)
     
  • A vacuum evaporator that treats 100% of the waste water from electroplating and returns it to the production cycle. This means that only the waste water used for personal hygiene (washbasins, showers, toilets) flows into the public sewer system, but not the waste water from electroplating – this is completely recycled via the vacuum evaporator!
     
  • 2020 but also because of the lower production output due to the pandemic restrictions

Altogether 64% of the total water demand (i.e. all waste water from electroplating) is recycled at the headquarters!

Our targets

Fulfilment date: 2023

How: We want to further reduce water consumption at the headquarters, through further process improvements in electroplating and by installing new valves in shower/washing facilities to regulate the water supply in a more resource-efficient way.

Positive effects: These measures are intended to reduce water demand from 4,031 m³ per year (as of 2019) to a maximum of 3,500 m³ per year from 2023. In addition to the environmental benefit, this would also be a saving of €4 per m³.
