    Treatment of Solid and Liquid Tannery By-Products

  • Original language description

    The tanning industry processes raw hides and converts them into leather. The solid tanned by-products contain chromium and by-product liquors contain residual chromium. Recycling of solid by-products (chrome-tanned leather shavings) was realized throughenzymatic hydrolysis which is an economically and ecologically acceptable process. Water soluble hydrolysate is thus produced, usable as fertilizer components, coating material, as an additive into adhesives mixtures, corrosion inhibitor etc. Recycling of liquid by-products (spent tanning liquors) utilizes solid residue, produced through enzymatic hydrolysis of chrome-tanned leather shavings, to reduce chromium content in liquor. The principle of dechromation consists in sorption of chrome from spent liquor to chrome sludge and is characterized by very high efficiency, simplicity and low investment requirements.

    Zpracování kapalných a tuhých koželužských vedlejších produktů

  • Czech description

    V koželužském procesu se produkuje značné množství kapalných a tuhých odpadů, které zatěžují životní prostředí. Tuhé vedlejší produkty obsahují chróm a kapalné produkty zbytky chrómu. Recyklace pevných vedlejších produktů (postružiny) byla provedena enzymovou hydrolysou, která je ekonomicky a ekologicky akceptovatelný proces. Recyklace kapalných vedlejších produktů (odpadní břečky) spočívala ve využití tuhého zbytku po enzymové hydrolyse postružin k sorbování zbytkového chrómu.
