More than 60 years’ experience

Tietjen are specialists in grinding

We strive to make sure our grinding solutions make optimum use of resources. This promotes optimal utilisation of waste and protects the environment. We combine well-founded knowledge with many years’ experience and faithfully implement your requirements. Our team of creative thinkers and specialists devote their lives to our individual grinding solutions – from the raw material right up to the moment we hand over the perfect facility for the production of pet food or aquafeed, or pulping of biomass. We don’t just crush what you want, how you want. We also sift, separate and mix according to our customers’ requirements. We plan and install custom grinding assemblies for you.

Research and development

The amount of plastic waste is increasing from year to year. Biodegradable packaging is therefore becoming increasingly important, and not only in the food industry. Yet there are already many sustainable packaging alternatives – such as bio-film made from macroalgae. Since this process is very time-consuming and expensive, Ludwig Schmidtchen, a doctoral student, has developed a cheaper and faster manufacturing process for this film. He received help from Tietjen.


Timber industry

The full decarbonization of our energy supply to meet the 2030 climate targets requires diversification of energy sources while maintaining or improving security of supply. Sustainable wood energy is the only renewable, on-demand, baseload partner technology of photovoltaics and wind energy at power plant scale. Wood pellet fuel is already available today, is in sufficient supply in the long term through a global market, and can thus secure our energy supply and grid stability for tomorrow.
