Compell: the sustainable leather for tanneries




100% compostable leather. An idea become reality, an innovative way towards an increasingly sustainable tanning industry. Let's talk about Compell, the new product developed by Alberto Rosi, ready to land on the leather market after a long period of research and tests that have certified its effectiveness and quality.


Alberto Rosi is a company that has distinguished itself for over forty years in the search for quality leathers and innovative processes. "Compell is a project that was born from the desire to give life to an exclusive material that meets the demands of a market increasingly oriented towards the reduced environmental impact, both of the production process and of the "end of life" of the product"-the company's owners explain. 


Compell is therefore proposed as a stabilized, highly versatile and quality semi-finished leather that allows tanneries, through the retanning process alone, to obtain a biodegradable, vegetable and metal-free finished product.





As well as considerable savings in water and energy use during the production process. 
"The very low content of bisphenol and the absence of glutaraldehyde and metals make Compell a leather whose waste is suitable for compost production," say the owners of Alberto Rosi again, "thanks to purely chemical characteristics that make it nutritious for the soil.


Compell is already a two-step certified product: analysis of the total amount of metals within the leather according to the UNI EN ISO 17072-2:2019 standard and reference to the UNI ENI ISO 20200 method, which defines the degree of disintegration of the leather under specific conditions. According to that standard, at least 90 percent of the sample subjected to the physical test must destroy within 45 days under the conditions dictated by the method. Compell has had 100% disintegration found in periods ranging from 10 to a maximum of 21 days. 

But what are the next steps for the future?
"The goal is to make Compell's life cycle totally circular, where even shaving and trimming waste can be disposed of and used as compost or for fertilizer production," the owners conclude.
