An evaluation of the technical performance and cost effectiveness of a low temperature pyrolysis process which uses dry leather tanning wastes to provide energy and chrome tanning liquor for reuse in tanneries is presented. Presently, leather waste is disposed of in landfills, resulting not only in a considerable loss of potential energy (estimated to be 0.7 trillion Btus annually), but an even more significant loss of chromium (estimated to be 1.8 million pounds per year). The pyrolysis process is shown to be technically feasible, economically viable, and can alleviate a leather waste management problem that is becoming increasingly more difficult to handle because of more stringent environmental waste disposal requirements. Leather tanneries can save an estimated $7 to $8 million annually by employing this pyrolysis process to conserve energy and chrome in dry tanning wastes.
