As the world turns to alternative fuels and renewable energy technologies, big corporations seem to be getting greener quarter after quarter. So, it's no shock to learn that PepsiCo has been quietly working at their own green goals in part by reducing their water usage by 45% between 2000 and 2008. In fact, PepsiCo plans to take their UK chip factories completely off the water grid by harvesting water from their own potatoes.
The potatoes the company uses now are about 80% water and PepsiCo uses close to 350,000 tons of potatoes every year. In addition to harvesting the water from their potatoes, the company has been testing a new irrigation device that measures the moisture in the soil and compares that to the weather forcast to conserve water usage during growing. Finally, PepsiCo will be moving to new varieties of potatoes that require less water.
But why become water-independent? Well, according to PepsiCo, their efforts are preparatory. Anticipating water shortages and the problems that climate change could bring about, they want to be ready for it, and it looks like they'll be successful. Will we see other companies turn their focus to reducing water-dependence in the near future? You betcha.
