Plagiarism & Co. is no trivial offence, even for politicians

The discussion about possible plagiarism in the book of the German Green Party chancellor
candidate has already almost disappeared from the headlines because of the terrible flood
disaster in Germany. In defence of Annalena Baerbock’s “writing”, lawyers argued, among
other things, that the criticized passages were not plagiarism because the book was not a
scientific work, but just a non-fiction book. This argumentation, which may be legally correct
but is morally highly dubious, has been tackled by the historian Julien Reitzenstein in a clever

“Hannah Arendt once said that it is not the case that the thief does not know the property right.
He allowed himself an exception in his favour. Baerbock did the same. She knew authors had
worked for the texts she copied. She allowed herself an exception in her favour.” *

The creation of texts is, as Reitzenstein very correctly points out, a laborious and usually not
particularly well-paid business. It must have been clear to the highly paid Green politician that
the text passages with which she and her ghostwriter filled the 240 pages by copy and paste
were created by people who do not belong to the top earners and that such impudence further
encourages theft of intellectual property that deprive the livelihood of many self-employed
authors. Would one want to put the fate of an entire nation in the hands of a person with such a
skewed understanding of property? Probably not. And now a second edition is to be published!
One is tempted to advise the publisher not to exacerbate the current shortage of paper with
another edition of “Baerbockiana”.

In my role as editor I am pleased to publish lot of guaranteed plagiarism-free content by renowned
experts in this issue of PU Magazine such as the findings of An Adams and her team from
Dow about the impact of the incorporation of recycle polyols on VOC emission, free aromatic
amines and odor of flexible PU foams (p. 178). Talking about recycling polyols. We look at
the results from the EU backed project Iceberg (p. 187). Make with us another step towards
a circular economy for polyurethane and read about the Danish consortium RePURpose and
their technologies for the recycling of PU products (p. 176). Or dive deep into the exciting
polyurethane markets in Middle East with our extensive interview of Martin Kruczinna of Pearl
Polyurethane Systems (p. 172).

Enjoy reading

“We enable our customers to succeed in an ever-changing, competitive environment.” - Interview with Martin Kruczinna, CEO of Pearl Polyurethane Systems

In February 2021, Pearl Industries Overseas Ltd signed an agreement to acquire the remaining 51 % shareholding in Pearl Covestro Polyurethane Systems LLC from former joint-venture partner Covestro AG. Headed by incoming former-Bayer executive, Martin Kruczinna, who will take over the role of CEO, the newly independent company has been rebranded Pearl Polyurethane Systems LLC. Both parties have reconfirmed their ongoing partnership through a long-term supply and technical service agreement. Pearl Polyurethane Systems offers a comprehensive range of polyurethane formulations and prepolymers for the production of high-performance PU foams and elastomers. PU Magazine took the opportunity to talk to the new CEO, Martin Kruczinna, about the current challenges facing the PU industry in the Gulf region and the company's plans for the future.

Another step towards a circular economy for polyurethane. Danish consortium RePURpose develops new technologies for the recycling of PU products

Danish researchers have developed a chemical recycling method for polyurethane (PU) targeted at handling end-of-life products. The method breaks down polyurethane into chemical building blocks that serve as feedstock for new PU products. According to the researchers, the chemical recycling process is robust and will, for the first time, be able to convert a wide variety of different PU materials.

The need for bio-based carbon in a sustainable future. Studies on support to research & innovation policy in the field of bio-based products and services

Carbon is the basis for a multitude of processes on our planet, many of them as parts of human economic activities. However, in a time, when “decarbonisation” is on everybody’s lips as the solution to the climate crisis, it seems almost ironical to run a project on “carbon economy”. What were the reasons behind this focus and what are the objectives achieved?

Material recycling in a circular economy for plastic – a critical assessment

In order to raise the discussion on the topic of Circular Economy for plastics to a fact-based level, CreaCycle GmbH, EPC Engineering & Technologies GmbH and Lömi GmbH have developed a position paper that addresses all parties involved in this topic. They call for the improvement of the current terminology of the relevant waste directives, including the incorporation of the latest available technologies for plastics recycling, such as solvent-based purification/dissolution. They propose an EU directive specifically for plastic waste, allowing for a recovery hierarchy based on physical and chemical processes. In addition, the paper addresses the need for improved sorting capabilities for material recycling and a regulatory framework that ensures end-of-life costs are considered. Finally, the authors call for the recognition and inclusion of solvent-based purification/dissolution as material recycling for the purpose of calculating recycling quotas.

Pioneering the chemical recycling of building materials. Production of recycling polyols from post-consumer PU/PIR waste for EU backed project Iceberg

Rampf Eco Solutions GmbH & Co. KG has been tasked to develop chemical solutions for the recycling of building materials in the EU backed project Iceberg. Using solvolysis, the company based in Pirmasens, Germany, is producing recycling polyols from post-consumer PU/PIR waste such as polymeric insulating foams.


Significant rise in order intake generates momentum for 2021. German plastics and rubber machinery industry sets out on a new high

German manufacturers of plastics and rubber machinery can look back positively on 2020, a year marked by the coronavirus, and despite the exceptional overall situation. “After a difficult start, which was characterised by major challenges including a lockdown, incoming orders showed a rapid increase from the summer onwards,” said Ulrich Reifenhäuser, Chairman of the Plastics and Rubber Machinery Association in the VDMA. This was particularly noticeable in those sectors where hygiene is important, i.e. mainly in the packaging and medical industries.

Research project on a new analysis method for microplastics

The plastics technology centre Aimplas in Paterna, Spain, announced that it is now implementing the “Microplastics_2020 Project”, funded by the Valencian Institute of Business Competitiveness (IVACE). The aim of the project is to develop a standardised methodology to detect, identify and quantify microplastics (plastic fragments of 5 mm or less in size) to monitor their presence in the different stages of industrial processes.


Impact of the incorporation of recycle polyols on VOC emission, free aromatic amines and odor of flexible PU foams

As part of the global transition from a linear economy towards a circular economy, Dow Polyurethanes has been investigating the recycling of PU foam from end-of-life (EoL) mattresses. After optimization of the foam recipe, recycle polyols obtained after chemical recycling can be used to substitute 25 % of virgin polyol in new slabstock PU foam formulations without compromising physical-mechanical properties. For applications in indoor environments, it is important to understand the impact of the incorporation of recycle polyols in PU foams on resulting volatile emissions and odor. Therefore, PU foam samples with recycle content were analyzed with different standard methods to collect reliable data on volatile organic compounds (VOC), volatile aldehydes, and extractable free aromatic amines. In addition, foams with and without recycle content were presented to a human sensory panel for odor assessment.
