Recycling Chocolate Moulds – Recycling Schokoladenformen

For Hans Brunner GmbH, sustainable business is an essential part of the corporate philosophy. Specially trained personnel, training sessions, long-term investment and energy efficiency in production are areas we have taken into account in our decision-making for a long time now. For decades, production remnants which accrue, such as for example metals, plastics or paper, have been separated on site and sent for recycling as part of the materials cycle.

Thanks to their long service life, our high quality moulds also play a part in conserving resources. However, we have gone one step further, and offer solutions for reusing our moulds:

The used polycarbonate moulds are separated by colour and then supplied to the recyclable materials market. The sorted material is then sold to a manufacturer that can directly use polycarbonate as a raw material for its own products.

This saves natural resources, which would otherwise have been used to produce new polycarbonate.

There is also a solution for chocolate moulds containing metal components: Previously, at some expense, these had to be disposed of as waste metal. In early 2012, we entered into a partnership with the Steinhöringer Werkstätten (Steinhöring Workshops), a social organisation offering work to people with mental

or psychological disabilities, which professionally dismantles the moulds. Plastic, metal components and magnets are carefully separated, so they can be reused.

After the appropriate processing, metal components such as the elbow in Brunner centrifuge moulds (SE moulds) can be directly reused or supplied to the recycling market as scrap iron.

Neodymium magnets can be directly reused. As permanent magnets, they retain their magnetic properties, unless they have been exposed to high temperatures. The carefully removed magnets therefore undergo a strictly regulated sorting and inspection process before they are used in chocolate moulds again. Many years ago, Brunner developed a process in which the magnets are completely covered by plastic. This ensures the magnets do not come into direct contact with the chocolate, without negatively affecting their magnetic force.
Only new polycarbonate is used for manufacturing Brunner’s moulds.

January of this year sees BRUNNER start a long-term research project with external partners. The aim of this project is to establish a recycling procedure that receives EU certification, so that moulds certified for use for contact with foodstuffs can be produced from used chocolate moulds.

The topic of sustainability has been extremely important for us here at BRUNNER for many years now. Here you can read about what we have already successfully implemented in recent years, and also what we plan for the future.

Our sustainability mindset has been very important to Brunner for many years. For this reason the residual materials left over from production have for many decades been separated on site and sent for recycling as part of the materials cycle. Thanks to their long service life, our high quality moulds also play a part in conserving resources. We've also provided a solution for the recycling of our used moulds for many years.


Reducing our CO2 output has been important to us for a long time. Even 10 years ago we invested in heat recovery and comprehensive building insulation. Other milestones followed, such as switching from oil heating to woodchip district heating in 2009, and the use of green electricity since 2012. This allowed us to reduce our CO2 emissions by more than 80%.

Die Verringerung unseres CO2 Ausstoßes liegt uns schon lange am Herzen. Bereits vor über 10 Jahre haben wir in Wärmerückgewinnung und umfangreiche Gebäudeisolierung investiert. Meilensteine waren danach die Umstellung der Ölheizung auf „Hackschnitzel“- Fernwärme in 2009 und der Bezug von Ökostrom seit 2012. Dadurch konnten die von uns verursachten C02 Emissionen um über 80% reduziert werden.
