Frito-Lay is jumping on the green bandwagon and is planning an environmentally neutral potato chip! According to the International Herald Tribune their goal is to take the Casa Grande Plant off the power grid and run it on renewable fuels and recycled water. They plan to install high-technology filters that would recycle most of the water used to rinse the potatoes, then burn the leftover sludge to create methane gas to run the plants boiler. They will also plant 20-50 hectares of solar concentrators for solar power. This is scheduled to be completed by 2010 and will reduce electricity and water consumption by 90% and the use of natural gas by 80%, which will chop greenhouse gas emissions by 50% to 75%.
This sounds like a fantabulous idea but I hope they are thinking of using organic potatoes!
