Seems like Ford wants us to believe that they are committed to building a more environmental-friendly car by using agricultural waste. Fact is, with the substantial increase in the raw material (petroleum) for their plastics, they are just looking to save gobs of money.
They cite saving landfill space by utilizing discarded tomato skins and such. At least here in California, agricultural waste (like almond hulls and shells, tomato skins, pomace, stones from stonefruit and more) are sold as cattle feed, composted, used in biomass cogeneration plants, processed further to extract essential oils or other chemicals, and doubtless others. Nothing goes to waste in the food processing business. Heinz is interested because they can charge Ford a higher price for the tomato skins than they can charge a farmer so that he can mix them in with his cattle feed, or whatever else they were used for.
