Three recent announcements from food and beverage companies use the word regenerative—either applied to sustainable agriculture or water.

Water. We can’t live without it, and you can’t run a food or beverage plant without it. However, having it available for all earth’s inhabitants worldwide in the next 20 to 30 years will be a challenge—as already two-billion of the planet’s population live in areas where water is scarce. Unsurprisingly, the food and beverage industry is one of the largest water users, so it’s well worthwhile to minimize waste wherever possible. Water treatment companies are only too aware of the importance of conserving this precious resource, which in some areas can be more valuable than oil.

Aquacycl used bacteria to clean up a wastewater stream and generate enough electricity to run the system and produce clean water.

A Nestlé Waters bottling plant is the first food and beverage factory in the world to earn the highest certification under the rigorous Alliance for Water Stewardship Standard.

Diageo will try to make its new Bulleit whiskey distillery in Kentucky carbon neutral, electrifying the boilers with renewable power as a step toward the company’s climate change goals.
