»4 important drivers for industrial water efficiency

From ReThink Water White Paper:

“Water is essential to our product. Without water, no beer. We are constantly looking for ways to reduce our water consumption and to ensure a sustainable use of water wherever we operate” ESKILD ANDERSEN Group Environmental Manager CARLSBERG

=> Business Continuity !!!

»Water Scarcity & Corporate Risk

»Environmental Protection & Regulation –

Water consumption decrease motivated by water prices

and regulation on wastewater discharge !?

sector

• Water risks and connected opportunities are drivers for industrial water efficiency !

• Promising technologies, solutions and competences are in place for industrial water efficiency !

• Do we see enough innovation and start-ups on industrial water technology ?

• What is the right balance between regulation (water use and wastewater discharge) and the need for industries to be able to compete in the global business environment ?

• There might be a need for simplifying /clarifying rules on: When is treated processwater fit for reuse ?
