In recent years, the biotechnology sector has become one of the fundamental pillars of the economy of León, with its impact accounting for a large part of the total economy of the region.

In addition, it should be noted that this biotechnology sector is the one that spends the most on R&D in the whole community, with a weight of 51.2% of the total invested in R&D, growing significantly compared to the 33.3% weight it had in 2014.

But how did it all start? The first company to set up and create this industrial base was Antibióticos de León, which is also the origin of ADL BioPharma.

Currently, the ecosystem surrounding León favours the growth of the biotechnology sector, among other factors, due to the presence of the University of León, which acts as a fundamental focus for the creation of talent, as it has several degrees related to the biotechnology industry.

Furthermore, ADL Biopharma’s facilities have the largest precision fermentation capacity in southern Europe, which together with more than 60 years of experience in different bioprocesses makes ADL, and the region, a global benchmark for the food and personal care industry.

Within these markets, we make available to our different clients all our capacity as well as all the knowledge we have accumulated over all these years.

In doing so, we continue expanding our business and helping more and more companies to produce products with high added value in an efficient and sustainable way.
