Interview: Petra Künkel on Collective Leadership

Version française


I am happy to share with you the first interview for CurvN. I had the pleasure to talk to a long time supporter of sustainable coopertions – Petra Kuenkel. She is a psychologist, founder of the Collective Leadership Institute, full-member of the Club of Rome, and has many years of experience in consulting multiple stakeholder collaborations for sustainability. Her acquired knowledge out of these manifold experiences combined with her profound education resulted in the Collective Leadership Compass that she presents in her current book The Art of Leading Collectively: Co-Creating a Sustainable, Socially Just Future.

Enjoy the interview!

In the infographic you’ll find my key take-aways from her book! Anyway, the book is definetly worth reading 😉

🇩🇪 Crowdfunding campagne to save the oceans from plastics with Pacific Garbage Screening!

10 days to go to support the crowdfunding initiative from Pacific Garbage Screening to reach the funding target of 200,000 €.

Why is it so innovative? Because it works without nets and, thus, is not harming any fish or living beings. The swimming platform only uses its unique architecture design to capture plastics and plastic particles.

Support Pacific Garbage Screening here!


Why is it so important to support this idea? 

Garbage and, especially, plastics have a strong impact on the environment …


… and garbage patches like this exist all over the world.


The world’s ocean currents …


… create these poisonous islands of floating plastic.


This is how it looks!

🇩🇪 Advancements in recycling of carbon fibre reinforced polymers

Source: Umweltcluster Bayern

Augsburg - Umweltcluster-Carbon

The cross-cluster project of the Bavarian Environmental Cluster (UCB) and the top level cluster MAI Carbon of the Carbon Composites e.V. (CCeV) has now announced results. The speakers gave insights on recycling and disposal.

Aircraft, automobile or bicycle – the industries are versatile when it is to be light and stable and carbon fibre reinforced polymers (CFRP) are used. The composite material has an enormous potential for lightweight construction, which is to be used more and more frequently in the future. It is therefore very important to devote a great deal of attention to the question at the end of the life cycle of CFRP. Therefore, CFRP-containing waste streams will increase significantly in the future and new challenges for the recycling industry will arise. Unused recycling potentials and alternative disposal possibilities are central issues for both manufacturers and waste disposal companies.

The MAI UCB project, which was launched in October 2016, between the Bavarian Environmental Cluster (UCB) and the top level cluster MAI Carbon was devoted to issues related to the disposal and recycling of carbon fibre-containing waste. The aim of the project was to identify and elucidate intelligent and sustainable solutions for the recycling and disposal of carbon fibre-containing residues. It was about the development of a sustainable basis, which initiated processes over the duration of the project, which further develops the utilisation of CFRP and anchors it in Bavaria.

Apart from the established pyrolysis numerous new fibre-matrix separation processes are currently being tested. Solvolysis, supercritical water, induction heating and electromagnetic commutation are still in their infancy. If the fibre is successfully separated from the matrix, there are new paths for further processing. Fibres which are preserved in long pieces are processed into tapes, yarns or nonwovens. Short fibres and dusts can be processed by injection moulding. The goal is to use the fibres again and again. Even the shortest fibres can significantly increase the mechanical properties of injection moulding compounds.

CFRP can neither be deposited due to the carbon content nor burned in conventional waste incineration plants because of the stability of the fibre. Tobias Walter presented a solution from AlzChem GmbH at the one-day event at the Technology Center Augsburg (TCA). They tested successfully CFRP waste from raw material for the production of calcium carbide.

Furthermore, the results of the Georgsmarienhütte GmbH were presented, which successfully tested CFRP waste as a primary carbon substitute in steel production. Likewise, the special waste incinerator Indaver also carries out a thermal utilisation of CFRP with great success.

The contributions of the new methods for utilisation of CFRP were accompanied by scientific contributions from RWTH Aachen University and TU Dresden. Mrs. Maria Reiter from Fraunhofer IGCV presented the challenges in the life cycle assessment of CFRP recycling methods. Here, too, it became clear, depending on how and where the material is used, that it can be ecologically sustainable.

In summary, it should be noted that CFRP is a material in development. The current opinion that CFRP is not sustainable is obsolete. The technologies for a sustainable use of CFRP are already in place and are certainly in use. New applications of recycled materials are found almost daily. Decisive will still be the price. The trend continues to show downwards. The theme day “Utilisation of CFRP-containing waste” showed that there are quite marketable business models for disposal and recycling, which, however, must be expanded even more intensively for the mass market.

“For the further success of this material, it will be important that we develop value-adding prerequisites,” Prof. Dr. Volker Warzelhan, Member of the Board of the Carbon Composites e.V.

🇩🇪 Digital platform that connects machines to improve production processes has been launched

Machinery and technology provider ThyssenKrupp has launched a digital platform that connects machines to each other in order to improve production processes, including for recycling.

‘Thanks to Toii, all machines can communicate with each other,’ says the company. ‘Due to predictive maintenance, the platform is also supposed to forecast the necessity of machine services in the future.’

The name Toii is a double play on words: it spells IIoT backwards, the abbreviation for Industrial Internet of Things; and it is pronounced like the word ‘toy’ – ‘an indication of how the new platform makes linking heterogeneous machines to existing IT structures child’s play’.

‘Toii will be a milestone for our recycling machinery,’ the company’s Michael Ridder insists to Recycling International. ‘Within ThyssenKrupp, Toii also connects the machinery of our ThyssenKrupp MillServices & Systems company which is responsible for the slag management of our steel mills.’

More than ever, it is essential to find intelligent uses for slag products for which there is a strong market demand, Ridder believes. ‘Instead of dumping slag in landfill sites, we process it and produce high-quality products.’ These are used in, for example, road construction, landscaping, hydraulic engineering, as fertiliser for the agricultural sector, and in the cement industry.

🇩🇪 90% of mineral construction waste utilised


The European Parliament determined in Article 11(2b) of their directive on waste and repealing certain directives of 19 November 2008 that ‘by 2020, the preparing for re-use, recycling and other material recovery (…) of non-hazardous construction and demolition waste (…) shall be increased to a minimum of 70 % by weight.’

In Germany the initiative „Kreislaufwirtschaft Bau“ exceeded already the ambitious European utilisation goals by far. Michael Basten, chief executive of BBS – German Association for Building Materials, Non-Metallic Minerals Regd., announces ‘today mineral construction waste is almost entirely recycled and kept in the cycle of materials. This takes pressure of landfills and preserves primary raw materials. In the meantime over 12% of the demand for aggregates are covered by recyclable construction materials. Of the 202m tons mineral construction waste, accrued in 2014, 180.8m tons (89.5%) have been recycled environmentally compatible.’
