DexLeChem: Services in Chemistry for a Sustainable World

Our Green Chemistry startup DexLeChem was founded in 2013 as a spin-off of the German Cluster of Excellence UniCat "Unifying Concepts in Catalysis". We are changing the chemical-pharmaceutical industry with green high-tech services, creating a new state of the art with our innovations. Our multiple awarded company offers to develop the reduction or re-using of indispensable, expensive resources in production processes with novel, patented synthesis routes. Our cutting-edge services lead to clear cost advantages in the production (up to ~80% cost reduction in a single manufacturing step. Within a few years, we achieved to successfully enter the conservative chemical-pharmaceutical market. DexLeChem received outstanding testimonials for their work from big players such as Lonza, Boehringer Ingelheim, or DSM and has the vision to create a green chemical-pharmaceutical industry.

We are green:

We have a proven track record in the development of water-based chemical manufacturing instead of using crude oil based solvents (e.g. micellar catalysis or microemulsion). We are highly committed to the 12 principles of our Advisory Board member Prof. John Warner, the founding father of Green Chemistry and use renewable resources whenever possible. In this way we help our customers to directly address the United Nations Sustainable Development Goals (SDGs) 3, 6, 8, 9, 12, 13, 14, and 15, support the EU Green Deal agenda by contributing in finding solutions for the biggest societal (and environmental) challenges of our time. We provide you with untapped green business opportunities - use the piece in process development that makes the difference!

We are smart:

We follow a "whatever works" approach in order to develop, optimze or scale-up chemical manufacturing processes (dynamic white-box modeling, advanced data analytics & machine learning, quantum chemical simulations, force-field analyses, molecular dynamics or genetic algorithms). We create competetive advantages in the interface of chemistry, physics, mathematics and data sciences for our clients enabling them to concentrate on their core competencies - the manufacturing of chemicals and pharmaceuticals. This results in a higher reliability, robustness, reproducibility as well as product quality and compliance.

We are collaborative:

We know what we can do and where our limits are. Our broad global network in Europe, the US as well as Japan and South Korea helps us to identify the best partner for each challenge. We strongly believe that securing access to knowledge will decide about the competetiveness of companies in the future.

Innovative catalyst technologies cut costs

New routes of synthesis are increasingly important in view of scarce resources. In fact they are indispensable in order to achieve the German "Chemiewende" (transition of the chemical industry). Our experts in catalysis develop cost-efficient routes of synthesis for noble metal catalysts providing high selectivity and yields.
