Analysis of the environmental impacts of waterproofing versus conventional vegetable tanning process - A life cycle analysis study

Waterproofed vegetable leather is desired for its 'greenness' in front of chromium-tanned waterproofed leather. However, conferring waterproofing capabilities to vegetable tanned leather maintaining light color and a soft touch is a fact of great concern for leather goods producers. Sustai...
