We offer you a new leather biodegradability test performed in our laboratories. On this occasion the samples are bovine crust, which have been tanned using different processes. These tests allow us to evaluate the degree of biodegradability of the leathers and thus determine which products are more sustainable for the environment.

In this second test we have analysed the following samples:

1) Crust tanned with chrome and retanned with standard market products.

 

2) Crust tanned and retanned with vegetable polymers.

 

3) Crust tanned with SERTAN AL and retanned with standard market products.

 

4) Crust tanned with SERTAN WT and retanned with standard market products

 

5) Crust tanned with SERTAN WT and retanned with vegetable polymers.

During the test we buried the skin samples in compost substrate on September 2, 2020 and unearthed them on October 5, 2020. After thirty-three days the result is surprising and unexpected for the entire Quimser technical team.

We observe that in 30-35 days the leather tanned with SERTAN WT begins to decompose. We emphasize that in EA-R-19170 (sample no. 5) the decomposition is greater, which leads us to affirm that within a year and under specific conditions of humidity and temperature, the skin will be totally decomposed.

Article EA-R-19170 (sample no. 5) has been retanned with natural polymers in order to have the minimum impact on the environment, both in terms of the resulting leather and the products used throughout the process.
