Abstract

The article is devoted to the analysis of the level of environmental friendliness of the chromium tanning process carried out with the use of modified montmorillonite.

Leather technology has a complex technological sequence of processes and operations for the processing biogenic material. The leather technology is based on a set of various, consistently performed processing of leather raw materials and semi-finished products. The technology uses chemical materials that are not always environmentally friendly. The principles of greening provide for complete or partial exclusion of environmentally unfriendly materials from technological processes. The eco-destructive impact on the environment of chromium tanning was established. Therefor an innovative direction of eco-friendly leather production is the partial replacement of tanning compounds of chromium with other structuring compounds that have a structuring effect.

The aim of the work was to determine the ecological efficiency of the technology of manufacturing leather obtained using modified montmorillonite. The object of research is the process of formation of leather properties in the process of tanning with the use of modified montmorillonite.

Environmental friendliness of chromium tanning technology with the use of modified montmorillonite is substantiated by: efficiency of formation of dermis structure; increasing the level of leather quality indicators; partial replacement of chromium compounds during tanning.

The technology provides: reduction of the negative impact on the environment of leather production; reducing the amount of chromium compounds in the tanning process; reduction of production costs for purification of waste liquids; increasing indicators of biological and chemical oxygen consumption; obtaining after tanning potentially biodegradable wastewater.
