When Thomas Authmann talks about his work, one thing becomes clear right away: his passion lies not only in technology – but also in people.
For the past 25 years, he has been with Doppstadt, playing a key role in building up international sales. Today, he manages customers across West Africa, from Morocco to Namibia. His experience in development work, his technical expertise, and his cultural understanding make him a true bridge-builder – between manufacturer and customer, between ideas and practical applications. In this interview, he shares his beginnings, highlights special projects, and explains why listening is often more important than selling.
Mr. Authmann, what was your professional background before joining Doppstadt, and how did you end up there?
I studied agricultural engineering and then worked for two years as a design engineer at a manufacturer of handheld motorized equipment. It quickly became clear to me that design work was not my passion. Instead of doing community service, I spent four years in development aid in West Africa – working on projects such as solar dryers for food preservation and supporting local crafts. That’s also where I learned French.
Back in Germany, the job market for mechanical engineers was difficult, so I initially went into agricultural machinery trading. Through one of my customers there, I eventually came to Doppstadt. The combination of technology, direct customer contact, and international assignments immediately appealed to me.
What fascinated you most about working in sales – especially at Doppstadt?
Above all, the role as a link between manufacturer and dealer. In engineering, I had very little direct contact with customers, and I really missed that exchange. In international sales at Doppstadt, I was able to use my language skills, build close customer relationships, and apply my technical expertise to practical problem-solving.
My goal was never just to sell machines, but to find the right solution for each customer’s challenge. Entering the recycling industry was particularly exciting for me – it was a new field at the time, but one that quickly turned out to be highly diverse and full of learning opportunities.
Which markets are you currently active in, and what makes your work there unique?
Right now, I focus mainly on the African market – working with dealers in Morocco, Algeria, and Namibia. I’m currently in the process of developing business in Egypt and, with the support of the German Chamber of Commerce Abroad, I’m looking for a suitable partner in South Africa.
My time as a development worker in Mali plays a big role here: I know the countries and people, I speak the language, I have cultural understanding, and I enjoy a high level of trust on the ground. A good example is the delivery of a machine to a composting plant in Mali. Years later, it was still in perfect condition – partly because the operator had strictly followed the training I gave him at the time. That really shows how vital trust and genuine relationship-building are in international business.
How have you experienced the development of Doppstadt and its machines over the past 25 years?
When I first started at Doppstadt, it was a pioneering time. Many things were still being built up – including international sales, which I was fortunate to help shape. Back then, the first steps toward computer control were being taken. Today, digitalization is indispensable – driven both by legal requirements and modern engine technology.
Culturally, much has changed as well, since Doppstadt has grown so quickly. But what has remained is our focus on flexibility – especially when it comes to customer consulting. Looking back, I can say: the recycling industry is and will remain a sector with a bright future.
I am currently responsible for the new Core Shredder Line – an exciting challenge in my career that already shows we are successfully positioned in the market. This role also offers great opportunities for personal growth and continuous learning.
Is there one project that stands out in your memory?
Yes – the development of the combination machine DZ 750. Technically, it was very demanding because it combined two shredding systems in a single machine. The first models were delivered to Scandinavia, and I was closely involved in supporting and further developing them – working side by side with Josef Doppstadt.
For many years, this machine was a cornerstone of our portfolio and underwent a fundamental redesign in 2012/13. Projects like this show how technology, market feedback, and close collaboration within the company can successfully come together.
