Conceria VICAR s.r.l. is skilled in producing hair-on leathers, particularly sheep hides, to manufacture high-quality articles for clothing, leather goods and footwear sectors. Conceria Vicar turns a meat industry by-product into a high-quality product thanks to its eco-sustainable philosophy and a modern, systemic, and cutting-edge industrial approach. The tanning process does not kill animals but recovers a waste product from the food industry, i.e., the hide that would otherwise be disposed of. According to the company, this means being highly attentive to the whole chain, starting from the origin, hence assessing the animal’s welfare through a system ascertaining breeding, transport, and slaughtering conditions. Vicar is a stunning example of a highly sustainable industry. It purifies water, treats sewage sludge, and recovers tanning by-products: a circular economy model that is pivotal and vital for our environment today. The aim is to achieve a perfect equipoise between industrial production and environmental impact that is steadily optimised and improved. The philosophy of using a “residue” is a key concept in the circular economy: designing products where what is now intended as a waste is a resource for a new production cycle.
