Water consumption significantly reduced since 2010

EVVA’s headquarters are located in a water conservation area, which is why it is important to us to use this resource sustainably. 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 approx. 20% of production facilities, as well as for electroplating (surface treatment of products) and personal hygiene.

EVVA has continuously reduced water consumption at the headquarters in order to conserve this resource as much as possible. In 2010, EVVA consumed a further 7,153 m³ of water. In 2023, demand fell to 4,050 m³ (measurement data for 2024 will only be available in the course of 2025). Of these, 4,044 m³ are for personal care/hygiene and only 6 m³ for electroplating. Thanks to the vacuum evaporator (see below), EVVA requires almost no water for electroplating, and consumption is minimised to 250 litres per 100-hour cycle.

EVVA has thus managed to reduce water consumption by over 40% since 2010 through wastewater recovery and optimisation measures. 1.13 litres of drinking water are saved for each EVVA locking cylinder that our retail partners and customers use - with an average new system size of 100 cylinders, this is 113 litres of drinking water.
 
Lower fresh water consumption

Reasons for water savings in recent years:

• 

  EVVA uses many clean production machines that do not require water 


• more efficient manufacturing and water treatment processes in electroplating (for the surface treatment of our products). Among other things, this was made possible by a new, modern wastewater treatment plant. Alkali (mixtures) have decreased in recent years, from 8,273 kg in 2023 to 6,968 kg in 2024
   
• New valves in the shower/washing facilities that regulate the water supply in a more resource-efficient way
   
• A vacuum evaporator treats the wastewater from the electroplating process 100% 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!
