Saving resources

We pursue the goal of constantly optimising resource consumption and making it more environmentally friendly. Early on, we focused on organic raw materials and developed an energy concept to reduce and compensate for CO2 emissions. We use FSC-certified materials for our packaging.

Organic production

We are organic pioneers: in 1991, together with Pronatec, we developed Switzerland’s first organic chocolate. Experienced employees regularly provide on-site support and training to the farmers in our cooperatives. Certification of all organic standards and transparency in the supply chain are part and parcel of our business.

Compostable foil

Biodegradable foil made from wood

Foil made from renewable raw materials has been a key topic for some time, but it is only recently that a product has become available that is not made from food, such as corn, but from FSC wood.

Certified as compostable packaging

The foil is biodegradable and certified according to both the American standard ASTM D6400 and the European standard EN13432 for compostable packaging. In addition, the foil has also been tested according to the “OK compost HOME” scheme, proving its suitability for use in a home composting system.

FSC certification

On request, we use paper and cardboard made from FSC wood for the packaging of our chocolates. We use inks that are suitable for food packaging in our printing processes.

Conserving resources

Bernrain energy concept

Heat recovery saves energy and water. Back in 1980, a special system for recovering waste heat from specific production processes was developed at Chocolat Bernrain in Kreuzlingen. The system carries 800,000 litres of water in a closed circuit and covers most of the cooling and heating requirements. The system, which required high investment costs, also saves more than 98% of the previous network water consumption annually. Furthermore, it allowed CO2 emissions to be reduced significantly.

Stella energy concept

When Chocolat Stella was extended, a modern and efficient energy concept was implemented. To meet our energy demands we use groundwater in addition to two chillers or heat pumps. In summer, this system works mainly as a chiller to produce cold water. Approximately 70% of the required cooling capacity can be covered by direct groundwater cooling. Where possible, the waste heat is used for heating purposes or returned to the groundwater. In winter and cooler times of the year, heat can be extracted from the groundwater or the cooling water circuit and used for base-load heating. With the new system, Chocolat Stella is able to significantly reduce its consumption of fossil fuels and lower its CO2 emissions.

Energy consumption

Solar power generation: In spring 2013, a photovoltaic system was put into operation on the roof of the warehouse building in Kreuzlingen. It produces about 30,000 kWh of electricity a year and reduces our previous annual CO2 emissions by 18 tonnes each year. The remaining power consumption is fully covered by electricity from Swiss hydropower plants.


Voluntary offsetting measures

The non-profit foundation myclimate is an international initiative that was founded in 2002 as a spin-off of the Swiss Federal Institute of Technology (ETH) Zurich and is now one of the world’s leading providers of voluntary offsetting measures. Based on sound scientific and business-oriented principles, myclimate offers a comprehensive package of climate protection measures in line with the principles of “avoid – reduce – offset”.

Complete CO2 offsetting for your production line

For our own Stella chocolate line, Chocolat Stella Bernrain supports a variety of myclimate projects and has been able to offset the CO2 emissions of a range of products from raw material through to sale. These are now labelled with the myclimate label and the corresponding tracking number, which can be used to access information about the supported project at

As a private label producer, we also offer myclimate certification options for your chocolate line. We would be happy to show you possible projects that fit your brand.
