Maqolada chorvachilik va parrandachilik chiqindilari – pat va jun tarkibidagi keratinning suvda eruvchan modifikatsiyasini olish usuli ko‘rib chiqilgan. Keratinning kimyoviy reagentlarga chidamliligi uning tuzilishidagi disulfid (sistin) bog‘lanishlari bilan bog‘liqligi ko‘rsatilgan. Patlarni xona haroratida 10% NaOH eritmasida ishlov berishda ular 24 soat ichida to‘liq erigan; natriy sulfid, natriy sulfit va vodorod peroksid ishtirokida esa 0,5% ishqor konsentratsiyasida 96 soatlik ishlov berishdan so‘ng to‘liq erish kuzatilgan. Natriy sulfid qo‘llanganda eritmadagi oqsil konsentratsiyasi patlar uchun 57 g/L gacha, jun uchun 48 soat ichida 43 g/L gacha oshgan. Taklif etilgan usul keratinning suvda eruvchan shaklini yuqori harorat va agressiv reagentlarsiz, yumshoq sharoitlarda olish imkonini beradi
