OSLO (Reuters) – Almost 16,000 desalination plants worldwide produce bigger-than-expected flows of highly salty waste water and toxic chemicals that are damaging the environment, a U.N.-backed study said on Monday.
Desalination plants pump out 142 million cubic meters (5 billion cubic feet) of salty brine every day, 50 percent more than previous estimates,
If you live in the developed world, safe water is usually just a faucet-turn away. And yet, global warming, drought conditions, and population growth in coming decades could change that, ushering in an era of uncertain access to water.
Now an MIT-based research team has evaluated those potential problems and, based on a case study in Australia, suggested an alternate approach to water planning. In a new paper, the researchers … [more…]
The world’s desalination plants, which use energy intensive processes to remove salt from water, produce enough toxic brine each year to cover all of Florida under a foot of water.
Factories around the world are pumping out toxic brine at a rate much higher than previously estimated and dumping it back into the ocean, according to a report published on Monday.
This super-salty brine is toxic to marine life, and … [more…]

A groundbreaking greenhouse that relies on sunlight and seawater to grow tomatoes officially opens next week, 300 kilometres north of Adelaide. The company Sundrop Farms spent several years developing the idea at a pilot plant on the outskirts of Port Augusta, before building a commercial facility that is 100 times larger.
