Champions of Sustainability Shine at “CarbonX” Week in Freudenstadt and Baiersbronn
From 18 to 25 July 2025, visitors to the Tal X Garden Show in Freudenstadt and Baiersbronn, Germany, explored the world of charcoal and biochar during the “CarbonX” theme week. Arburg participated as a sponsor with an exhibit in the glass pavilion located in the “Xentrum” and hosted engaging presentations under the theme “High-tech meets charcoal burning.”
At the heart of the event, an electric Allrounder injection moulding machine produced over 3,500 garden shovels from a sustainable material composed of 50% recycled polypropylene (PP) and 50% biochar—an innovative, CO₂-negative filler developed by Carbonauten. Visitors were able to take the shovels home as practical souvenirs of sustainable manufacturing.
Headquartered nearby in Lossburg, Arburg used the occasion to demonstrate its commitment to the environment and social responsibility. Michael Hehl, Managing Partner, stated at the kick-off event on 19 July: “This week is all about innovation, sustainability, and the power of change. As a global leader, we want to set a strong regional example for environmentally friendly production and business practices.”
Biochar, the highlight of the event, is made from pyrolysed plant waste such as wood chips and damaged wood. Once pulverised and compounded with recycled polymers, it becomes suitable for injection moulding. The material offers a promising route toward carbon-negative manufacturing.
During the panel discussion on 22 July titled “Conversations by the fire. Solving the climate crisis with biochar?”, Arburg application engineer Jonas Bletscher presented the company’s sustainability efforts through its arburgGREENworld programme. He emphasized that Arburg machines can process a wide range of alternative fillers including sunflower seed husks, paper, coffee grounds, and biochar.
Torsten Becker, Managing Director of Carbonauten GmbH, outlined the potential of biochar as a game-changing material in the fight against climate change. The event concluded with a panel discussion that highlighted biochar’s role in reducing CO₂ emissions and supporting circular, low-impact production.
