Sustainable enterprise

Is an important subject for Kornelis, but what do we mean by this? With all business decisions we are aiming at:

• Pursuing a higher operating efficiency
• Using opportunities for a better environment
• More well-being of employees and society

Kornelis is dedicated to this way of sustainability. We have developed a clear internal policy to ensure a positive contribution to sustainability. We constantly strive for the best way of producing to minimize the influence on the environment. We also offer our employees a pleasant and safe working environment.

Smart design

Our designs are based on minimal use of resources and maximum functionality. The design takes into account the minimization of production steps and we aim to use mono materials to enlarge the recyclability and reduce the waste. With the selection of raw materials the standards of the EC in the field of food safety are applied.
• E -cap; weight reduction of 30% at constant functionality. Where the production cycle and energy consumption is drastically reduced
• 2K (2 components) Syrup cap; this cap is produced within one production step in a mould where previously two moulds and an assembly step were required additionally
• offering mono materials with reference to
recyclability. Supply of PP cap in combination with PP liner

Work Environment

We offer our employees a safe, pleasant and inspiring working environment. In the open and social culture there are a lot of possibilities for personal development. Several departments use trainees who are guided properly and can take a look into the process from development to production of closures. We also give an important contribution to various community projects. In all departments a representation of our emergency response team is present.

Energy Efficient

The future of driving is electric motoring. Kornelis has already stepped in and has purchased some electric cars. Charging poles have been placed which not only can be used by us, but also by our ' green ' visitors.
In our entire property we use green energy and the default lighting is replaced with LED lighting.

Also, when buying new machines we closely look at energy consumption. The machine park has recently expanded with 3 electric machines that are much more energy-efficient than the existing machines. The cooling system we work with in the injection moulding process is a chemical-free system of which the environmental impact is minimal. Furthermore, the oil cooling system is a closed system.


We support various cultural and sporting activities within our region. In addition to the main sponsorship of ‘Kopje Cultuur ', the annual event of Steenwijk and surroundings we sponsor local events as ' Sail Giethoorn', ‘Skeelerklim’(inline skating) and ‘Het Wielerspektakel’ (cycling event). We select events that are accessible to all residents and in that way we want to indicate that we are part of the society and mean something to the population. We also support charities.


ISO Standards

We find product and food safety very important. For over 75 years our products have been produced in an environment that meets high production and quality standards. We are not only FSSC22000 certified, we also take part in the ISO26000 project.
