Cradle to Cradle mentions a kind of Frankenstein product (as far as recycling goes) man has made: Monstrous Hybrids. These are, "mixtures of materials both technical and biological, neither of which can be salvaged after their current lives." What a disaster! Citing the common leather shoe as an example, the author goes on to reveal how the particular amalgam of material and processes, including chromium tanning and the lead and plastics in rubber soles, make it totally unsuitable for recycling. Can we not design a better way to make shoes, with eco-friendly materials and chemicals? Such is one of our many, many tasks on the way to sustainability and zero waste.
