Corporate philosophy

Our actions and conduct are intended to preserve an intact environment and foster peaceful and prosperous cooperation of all human beings throughout the world, Europe, Germany, Lower Saxony, and in our immediate neighborhood.

Against this backdrop, we have developed a mission statement for our business conduct that is based on fairness, reliability and sustainability .

We seek to follow these three principles in our daily lives and our business transactions.

Human rights, the German constitution (or “Basic Law”), our Christian values and moral principles are the standards by which we are measured.

In this sense, we are committed to:

  • Protecting the environment and its natural resources by using renewable raw materials as feedstock, energy-saving and resource-friendly processes, and acting efficiently and effectively

  • Equal treatment of all persons and rejection of every type of discrimination

  • Fair, open, and honest dealings with employees and business partners

  • Engaging in business relationships among equals with comparable opportunities and risks

  • Maintaining long-term business relationships on the basis of honest and trusting cooperation

  • A well-trained and motivated workforce

  • A safe and congenial working environment for our employees

  • A solid and reasonable return on investment for the shareholders and financial partners

  • Free and fair competition and vigilance against all types of corruption

  • Compliance with national laws and regulations

We feel an obligation towards our environment and fellow human beings, in particular, however, towards our employees, customers, shareholders, suppliers and partners.


In 5 continuously operating distillation plants, on more than 330 days out of the year we produce highly purified neutral alcohol from grain, sugar beets and sugar cane. With a capacity of over 80,000 m³, we are among Germany’s largest producers of industrial alcohol.

We in large part developed the plants on our own and build them with competent partners from the region. This allows us to ensure that our standards for sustainable and highly-efficient production can be fulfilled. In production this means for us:

low use of energy and raw materials

practically no air emissions or pollutants

no waste disposal costs thanks to internal recycling

high degree of automation and thus low personnel costs

high safety standards and very low rates of stoppage

low fluctuations in quality thanks to IT-based product monitoring

In order to ensure and continually improve upon the high standard in production, at KWST, special emphasis is placed on initial and further training of employees. A high level of expertise is one of the critical success factors for the company.

The key production facilities are located at the Misburg site:

Rectification and dehydration

Wastewater recovery and recycling

Ethanol and molasses storage

Loading and denaturing facilities


In its long history, KWST has gained substantial experience on the topic of sustainability. Since the 19th Century, the company has been producing bioethanol with high efficiency on the basis of renewable raw materials and a highly-favorable CO2 balance. Power of innovation is one of our company’s key assets and has enabled us to continually expand ethanol production over several decades. Not least, this results in decisive advantages for our customers, which is also reflected in various certificates:

According to “DIN EN ISO 9001:2015”, we have been proving on an annual basis since 1997, that we manufacture products which in terms of product quality fulfill the statutory/regulatory requirements as well as those of our customers.

The “QS Certificate for the production of individual feed products + warehousing/handling” has certified regularly since 2009 the adherence to the standards of quality assurance for food.

The “OK Kosher” Institute has continually certified since 2010 that our products for the customers of a globalized world can be used responsibly.

In addition, we also have a certificate according to biofuels sustainability regulations (Biokraft-NachV) and based on sustainability regulation concerning biomass flows (BioSt-NachV) according to ISCC-EU, committed to reducing CO2immissions and thus protecting the climate.

Based on the requirements of the “Codex Alimentarius” and the key statutory regulations, our production continuously undergoes testing according to an HACCP study.

By involving all employees in the further development of the processes relevant to quality, we are constantly advancing our continuous improvement processes according to the theme, “achieving greater quality together”.
