This would seem to be a bit of a contradiction in terms the fact eco friendly and potato chips are actually mentioned in the same paragraph, but there is a bit of a green revolution going on not just in the world at large but also in the world of food and food production.

Some half a million potatoes are processed at the Frito Lay factory in Casa Grande, Arizona every single day, that’s a lot of oil, seasoning, packing, water and energy. Here are just a few things that the company are doing:

Installing high-tech filters to recycle most of the water used to rinse and wash potatoes, as well as the corn used to make other snacky goods

Burning the leftover sludge and harvest the resulting methane gas to run the plant’s boiler

Building at least 50 acres of solar concentrators behind the plant to generate solar power

Building a biomass generator to likely burn ag wastes for additional fuel

The factory refit will be finished around 2010 and there will be some serious eco savings, such as 90% saving on electricity and water, and gas usage will be cut by 80%, the humble potato chip is about the get a new image.
