Who is Derwent Group?

Derwent Group belongs to Grupo Tejedor Lázaro, a leading Group with 65 years of experience in the field of animal nutrition, health and wellness in the pet and aquaculture sectors.

We offer a broad network of services and a Team of professionals to help you achieve your goals.

We are specialised in engineering projects for aquaculture and animal feed factories, with proven experience thanks to projects carried out for our clients in more than 20 countries all over the world.

With the latest technology and through the design and execution of turnkey projects, we accompany you from the design phase to the launch of your factory, and even, thanks to our experience, in the operation of it.

Moreover, we have great experience in raw materials for animal nutrition, which allows us to offer the best resources through our trading service. Optimal logistics and our extensive international sales network enable us to offer the highest quality animal proteins, vegetable proteins and additives. And all this with the backing of two certifications with great international prestige: IFS (International Featured Standards) and Global G.A.P.

We are also specialised in animal nutrition, and we work with Dibaq Group to manufacture food for pets and aquaculture fish and to sell these products and associated services in more than 65 countries around the world. Applying our extensive experience, we strive each day to create healthy, high-quality recipes with sustainable raw materials and the most innovative technology.

We are mindful of the fact that all of this work is made possible by the support and energy of the people who comprise our group and the rest of our major stakeholders. The people who make up Derwent Group are the cornerstone of our Company, and we appreciate the efforts of our Team, suppliers and collaborators, as well as the trust of our clients, the institutions with which we collaborate, and the social groups around us. Due to their importance to us, we work every day to ensure their well-being and happiness, having been recognised with EFR Certification as a Family-Responsible Company by Fundación Más Familia.

Our Style

Thanks to the experience, excitement and passion of our Team, we are proud to say that our brand stands for Trust, Transparency, Coherence, Honesty and Safety.

We are also pleased to be committed to our stakeholders, from our clients and suppliers to our competitors, partners and social groups with which we collaborate, who we also consider part of our family. Our relationship with them is therefore based on the 4Hs: Humanity, Humility, Honesty and Happiness.

Our Strengths

At Derwent Group, we define ourselves as a company committed to the services we provide, our team and our environment.


We are committed to innovation, technology and development, but will never forget our roots in Fuentepelayo (Segovia) and the hard work and determination of our grandparents, José Luis Tejedor and Anastasia Lázaro. Our history and respect for the family legacy are what motivate us to learn and to forge ahead, looking towards the future.


All of us who make up Derwent Group are one big family, and we work together to offer our customers the best products and services with dedication, responsibility, and respect. People are our number-one asset, and we take care to ensure their well-being by defending diversity and equality on a daily basis, encouraging a healthy work-life balance, guaranteeing the safety of our team, and fostering growth. That’s why we have been recognised with EFR Certification as a Family-Responsible Company, and the AENOR Certification of Protocols against COVID-19.

A Positive Atmosphere

Our work environments encourage a positive, supportive atmosphere. This allows us to strengthen team spirit, cohesion between people, and the ability to overcome any obstacle. That way we can offer our customers and community the very best.

Hard Work

We have deep respect for a job well done, and every project and business we collaborate with is a new source of excitement for us. That’s why we strive to be the best professionals, and we work hard to address our customers’ new needs. We want to contribute our technology and know-how to your project, offering you personalised assistance, a 360-degree service and ad-hoc products.


We believe it is possible to grow in a responsible, sustainable way, taking care of nature and our environment.
