源于制鞋工業(yè)的固體廢料處理

摘要： 鉻鞣革和涂飾革在世界范圍內(nèi)每年帶來(lái)成千上萬(wàn)噸的廢棄物.文章研究了不同成革種類(lèi)在生產(chǎn)過(guò)程中帶來(lái)的廢棄物.通過(guò)酶法水解可將固體廢棄物分解成兩類(lèi)產(chǎn)品:低相對(duì)分子質(zhì)量(約10,000 Da)的可溶性膠原;含鉻和剩余蛋白的不溶性鉻餅.利用3步酶法水解固體廢棄物,同時(shí)根據(jù)水解物中的含氮量來(lái)表征水解的效率.在理論條件下,水解的有效率可達(dá)73%.膠原水解物含鉻量相當(dāng)?shù)?不超過(guò)100 mg/kg). Abstract： Chrome-tanned and finished leather clicking waste represents several hundreds thousand tons per year annually world-wide.The paper deals with the study on processing of leather wastes arising from leather (mainly shoe,garments,upholstery) industry.Solid leather waste was treated through enzymatic hydrolysis into two products:water-soluble collagen hydrolysate of low molecular mass (approx.10,000 Da) and remained insoluble cake containing chromium and residual protein.A 3-stage enzymatic hydrolysis was applied and the efficiency of the process was monitored by the degree of leather waste hydrolysis expressed by nitrogen content in collagen hydrolysate.Under proposed optimal conditions the efficiency of hydrolysis can reach up to 73%.Collagen hydrolysate thus prepared contains,in addition,very low chromium content (not more than 100 mg/kg). 作 者： P.Mokrejs    D.Janacova    K.Kolomaznik    M.Mladek    F.Langmaier    V.Vasek   作者單位： P.Mokrejs,M.Mladek,F.Langmaier(Tomas Bata University,Faculty of Technology,Department of Protein and Leather,nam, TGM 275,762 72 Zlin,The Czech Republic)
