An article in Sustainable Life Media (Oct 8, 2011) describes efforts at Frito Lay’s plant to reduce its energy and water impact. 67 % of the energy used comes from renewable sources – solar power. 75 % of the water used is recycled, Greenhouse gas emissions decreased 50 % and 80 % of natural gas usage is expected to be decreased through use of wood and agricultural waste as a source. Finally less than 1 % of the waste is expected to go to the landfill.  Should efforts to move to zero impact facilities be justified based on costs or based on regulatory compliance or PR benefit ? Do you expect proactive companies to benefit more than companies that wait until regulations demand such efforts ? WOuld you expect product designs to change to enable zero emission manufacturing ?
