LONDON: Ford has come up with a literal way to put old cash to good use. The automaker has explored a suitably convenient way to use old bills, shredded and decommissioned to a list of recyclable materials that will be used for cushions, insulation and other such components. Today, a whopping 10,000 pounds of paper money is shredded on a daily basis. Using this, including soybeans, denim and plastic bottles, Ford has come up with a great initiative to have its carbon footprint go a shade lighter. Also, Ford has cut its petroleum use by about five million pounds a year, using soy-based material for foam.
