With So Much Water on Earth, Why Are
We So Thirsty?
Some Critical Issues
Growing competition for
water resources
Water-energy nexus
Value from first generation
water efficiency efforts
largely captured
Outdated policy frameworks
Aging or missing
infrastructure
Tomorrows Needs Will Be Even Greater
By 2030*, we will need:
30% more water
40% more energy
50% more food

Description
Dow Terneuzen reuses
municipal household
wastewater twice in its
manufacturing process
Sustainability Profile
Dow accepts 10,000 m of water every
24 hours and purifies more than 70
percent of it to generate steam for its
manufacturing plants
Reduced energy use equivalent to
lowering CO2 emissions by 5,000 tons per
year
Process reduces the energy use for water
purification by 65 percent
