Mining the “Blue Economy”

Dow has a long history of appreciating the ocean as a precious resource – from the Company’s early work in extracting magnesium from seawater to desalination efforts in the 1960s. Today Dow is committed to finding science-based solutions to reduce plastic waste in oceans.

More Valuable Than Pirate Treasure


H.H. Dow had dreamed of using the ocean as a mine since 1924, but it wasn’t until January 21, 1941, that it became a reality. That was the date the first ingot of magnesium made from seawater was poured in Freeport, Texas – and the first time man had successfully mined the ocean for metal. The new plant almost immediately began making a major contribution to the Allied War Effort and the production of lightweight aircraft. Later named DOWMETAL, Dow’s magnesium became an important product for everyday uses in automobiles, tools and toys.

As one of the largest industrial energy consumers in the world, Dow has consistently been on the forefront of new energy technology improvements. Today, Dow is one of the largest industrial buyers of renewable energy, which is used to help power its manufacturing sites and reduce its carbon footprint. In Brazil, Dow is using renewable biomass and hydropower as an energy source. In Texas, Dow has entered long-term wind power purchase agreements for its operations.




On June 21, 1961, President Kennedy flipped a switch in the White House and sent an impulse to Freeport, Texas, that started a stream of fresh water spouting from the sea.

With a Push of the Button
It’s a WRAP



When Dow’s first desalination plant in Freeport, Texas, was activated in 1961, President John F. Kennedy said of the accomplishment, “This is a work which in many ways is more important than any other scientific enterprise in which this country is now engaged.” Since then, Dow has continued to produce elements that make desalination more efficient and affordable. With Dow’s technology, projects in water-scarce areas from the Middle East to California to Australia are now providing residents with affordable fresh drinking water from the sea. It’s been a tall glass to fill, but we’re doing it.


Stemming the Tide


To help stem the tide of waste than flows into the ocean, Dow has pledged $2.8 million toward collaborative efforts to reduce marine debris. The Company also became a founding member of the Trash Free Seas Alliance, a global initiative led by the Ocean Conservancy to develop land-based solutions to prevent waste from entering the ocean seas. As part of these efforts, Dow is participating in initiatives in Asia to track and stem the flow of waste. For example, Dow is working with the Indonesian government and other partners to help turn plastic waste into sustainable roads – paving the way to a more sustainable future.
