The utilization of waste animal hair and feather has been studied to aim the zero-emission. The easy extraction system of feather was established. Feather was made damp with water to reduce the volume, and extracted in low concentration alkaline solution at high temperature. These procedures were applying as a patent PCT/JP2005/005672 'Manufacture of hydrolyzed-keratin'.It was examined to the effectiveness of hydrolyzed-keratin for the cosmetic material. The damaged hair by experiment has been repaired with hydrolyzed-keratin by electronmicroscopic analysis. Moreover, the effects of the repair and protect of leather were recognized, and those data were applied for patent '2005-282444, 'repair and protect reagents of leather'.As the decomposing methods of animal hair and feather, the screening of the microorganisms to secrete the keratinase has been made a common study with Institute of Medical Micology (Teikyo University), Animal Life Science (Tokyo Univ.of Agri.and Technol.), and Tokyo Metropolitan Leather Technology Center. In those studies, some promising microorganisms and new detection methods of microorganisms were discovered.

以零排放为目标，对废弃动物毛、羽毛的利用进行了研究。建立了羽毛的简易提取体系。将羽毛用水润湿以减少体积，并在高温下在低浓度碱溶液中提取。这些方法作为专利PCT/JP 2005/005672“水解角蛋白的制造”申请。电镜分析表明，水解角蛋白对实验损伤的头发有修复作用。此外，对皮革的修复和保护效果也得到了认可，这些数据已申请专利'2005-282444，'皮革的修复和保护试剂'。作为动物毛发和羽毛的分解方法，筛选分泌角蛋白酶的微生物已与医学微生物研究所共同研究（帝京大学），动物生命科学（东京农业技术大学），东京都皮革技术中心在这些研究中，发现了一些有前途的微生物和新的微生物检测方法。
