The waste chicken feathers were treated with the enzymes (dissociating disulfide bonds) produced by thermophilic Meiothermus ruber H328, and then the treated feathers were milled and subjected to the hot-press compression molding. It was found that the recrystallization of the feather keratin was interfered with to some extent due to the lack of S-S bonds. On the other hand, the slight reinforcement of the feather resin with the wood fibers was effective to enhance the tensile behavior and the thermal stability of the feather resin.
