Waste, parings and scraps (WPS) in shoemaking industry are difficult to deal with by traditional approaches, which will pollute the environment and results in waste of resources if not handled properly. In this paper, WPS, after modification, is used as reinforcing material in gypsum block, in which livestock-waste based retarder is used to control setting time. The result showed that the proper mass ratio of hemi-hydrate gypsum to WPS is 95:5. The optimal dosage of retarder is 0.23% (on the basis of total solid). The addition of modified WPS remarkably improved the characteristics of anti-cracking, water absorption, dry shrinkage and thermal conductivity of the gypsum block, with little decrease in mechanical strength values.
