The efficient removal of proteoglycans, such as decorin, from the hide when processing it to leather by traditional means is generally acceptable and beneficial for leather quality, especially for softness and flexibility. A patented waterless or acetone dehydration method that can generate a product similar to leather called Dried Collagenous Biomaterial (known as BCD) was developed but has no...

leather artifacts have organic and degradable structure and some historic samples have remained from different historical periods. studies of these scarce specimens have a great importance in the conservation procedure by which the structural study of leather artifact for understanding production process and used materials can be achieved. for this purpose a historic leather bottle has been stu...

As the collagen protein market increasingly grows, it becomes a priority to explore a economic, stable, and environmentally-friendly extraction method to realize the high-value transformation of pigskin. In this paper, the structure of collagen protein is introduced first. Then five methods, which extract collagen protein from pigskin or a kind of leather industry waste-chrome shavings, are rev...

introduction Tannery waste management is a serious problem for tanning and leather industry facilities. Those branches generate large quantities of waste, consume substantial amounts of energy and in the general opinion are considered „air polluters”. The methods of tannery waste management applied thus far are insufficient, thus considerable portions of such waste are stored on landfills. The ...

A protease isolated from Pseudomonas aeruginosa PD100 could act in the presence of SDS and Tween 80. This protease could be useful for degradation of protein in the presence of solvent, dehairing of cow skin and degradation of natural proteins. The immobilized protease showed 15-20% increases in temperature stability and the entrapped enzyme retained 83% of its initial activity after six cycles...

As a global manufacturing sector, the leather industry has been critical player in international commerce market. With growing concerns about its sustainability, there tends to be an increasing number of studies academic literature as well grey (e.g. reports) focusing on supply chain management. However, is lack comprehensive review current research that illustrates relationships between sustai...
