Utilization Technology Of Collagen From Leather Waste

Relevant technical situation at home and abroad

Extract collagen as additives for feed, food and cosmetics; hydrolyze waste dandruff to produce gelatin; produce regenerated leather.

Preparation of surfactants; landfill or incineration.

Research and development contents

Using tannery waste dandruff as raw material, the adsorption and removal technology of heavy metals such as chromium and other heavy metals in tannery and other industries are developed.

Development and application of toxic inorganic anions adsorption and removal materials from leather waste dandruff

innovation point

High performance adsorbents for removing toxic heavy metals and inorganic anions from leather waste were prepared from leather waste.

The solid waste produced during leather making process is used to control the pollution of chrome produced in leather making process.

The key technology has been awarded national invention patent.
