The starting signal for recycling chocolate moulds

For Hans Brunner GmbH, sustainability has long been a matter of the utmost importance.

But also in the future, our stated aim is to be able to reuse material, and therefore conserve resources and protect the environment.

Since the middle of 2020 we have been the researching possibilities as to how to implement recycling loops for chocolate moulds. As part of this, we differentiate between materials that accrue as waste or remnants during production and material in moulds that our customers have already used.

We now have our own plastic mill, so we can crush leftover material arising during production to granulate, in order to test whether new chocolate moulds can be made from it. Series of tests are currently running, in which we are testing the recycled plastic’s material properties. Because we have the very highest quality demands, it is extremely important to us that even moulds made from recycled material fulfil our specifications and meet our customers’ high requirements.

Our long-term aim is to be able to produce moulds from material from recycled, used moulds – mould to mould (m2m).

Therefore, from January 2022, and in cooperation with external partners, we are starting a two-year research project. 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.

This project comprehensively covers the topic of recycling in all its facets. All aspects will be examined and documented, spanning recyclable mould design, decontamination, separation, crushing and rheological analysis of the recyclate won in the process.

Customers who want to use moulds made from recycled plastic therefore receive a completely transparent overview of the entire process and material properties. They are therefore able to decide whether to use recycled materials for their new moulds.

Recycling conserves resources. As a result of the multi-cyclic materials cycle, less waste is produced, fewer resources are used and, compared with newly manufactured plastic, the CO2 used for producing the material is reduced by around 20%.

In this way, over the long term, chocolate moulds can be produced more economically and in a way which better conserves resources, which is good for customers and the environment alike.

If you have any questions or suggestions, or would like to work with us, our recycling experts are always available to assist you at recycling@hansbrunner.de.

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.
