Continuing a partnership with this international chemical manufacturing company, he joined the Howdle group at the University of Nottingham for a PhD project looking into the industrial potential of scCO₂ dispersion polymerisations for additive production. After graduating, he worked in the Shaver group at the University of Manchester, developing a holistic approach to plastics recycling and sustainability across the many stakeholders in the field.

Indorama Ventures Public Company Limited, one of the world’s largest producers of recycled Polyethylene Terephthalate (PET) resin, announced the completion of the expansion of its recycling facility in Brazil, supported by a ‘Blue Loan’ from the International Finance Corporation (IFC), a member of the World Bank.

The recycling facility, located in Juiz de Fora, Minas Gerais, Brazil, is increasing its production capacity from 9 thousand tons to 25 thousand tons per year of PET made from post-consumer recycled (PET-PCR) material. The project is part of Indorama Ventures’ Vision 2030 ambition to continue building a sustainable global company, including spending $1.5 billion to increase its recycling capacity to 50 billion PET bottles per year by 2025.

PET is a unique and widely used plastic for water and soda bottles and the most recycled plastic in the world. Indorama Ventures, the world’s largest provider of recycled PET resin used to make beverage bottles, invested US$20 million to optimize its Brazil facility’s processes and acquire new equipment such as washing machines to help remove labels, grind bottles in water and reduce water consumption by 70%.

In November 2020, the IFC provided $300 million in Blue Loan funding to Indorama Ventures with the objective of increasing recycling capacity and diverting plastic waste from landfills and oceans in Thailand, Indonesia, Philippines, India, and Brazil—countries which are grappling with mismanaged waste and serious plastic waste in the environment. Blue Loan funds are certified and tracked for projects that support sustainable use of ocean resources for economic growth, improved livelihoods and jobs, and ocean ecosystem health. Indorama Ventures has secured a total US$2.4 billion in long-term sustainable financing from various financial institutions between 2018–2022 to support sustainability projects.

• ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

DSM, the inventor and manufacturer of Dyneema®, will be exhibiting at one of the leading events for homeland security and safety, Milipol Paris 2021, from October 19-22.

The performance characteristics of Dyneema® make it ideal for a variety of applications, including soft and hard armor ballistics to protect against today’s advanced and emerging threats. In addition, Dyneema® combines next-generation fiber technology and unidirectional engineering to deliver armor solutions with unmatched ballistic stopping power in a lightweight and flexible composite.

By implementing Dyneema®, body armor manufacturers are able to use less material in the development of their ballistic vests, plates and helmets. This leads to weight savings upwards of 30 percent when compared to competitive materials, without impacting ballistic performance. The lightweight construction of armor made with Dyneema® also mitigates injuries associated with the cumulative effects of daily armor use – while improving situational awareness, as well as cognitive and tactical performance.

While decreasing the load on the wearer, Dyneema® is simultaneously able to reduce the impact of material manufacturing on our planet. In line with DSM’s commitment to protect people and the environment they live in, we have developed the first-ever bio-based ultra-high molecular weight polyethylene fiber and unidirectional (UD) material. Bio-based Dyneema® boasts the same exact performance as conventional Dyneema® with a carbon footprint that is 90 percent lower than generic HMPE.

• Excellent project to encourage ingenuity among young students
• Experiment on biodegradability of textiles and nonwovens produces impressive results
• EUR 30,000 in prize money for a total of 209 participating schools in and outside Austria
• Lenzing views supporting these kinds of projects as part of its sustainability mission

Lenzing – The Association of Chemistry Teachers in Austria – known by its German abbreviation, VCÖ – has been holding project competitions that thrill students and take them beyond the traditional syllabus for 30 years. Every two years, it highlights a key topic for ninth- and tenth-graders to explore by conducting special experiments and learning from their observations and conclusions.

This year, the 16th installment of the competition is called, “Achieving a cleaner climate and a circular economy with chemistry”. These topics are also near and dear to the heart of globally active fiber manufacturer Lenzing. That’s why the company promptly announced that it was prepared to support this project competition in several different ways. First, Lenzing made a contribution toward the sponsorship fund totaling EUR 30,000. Second, it initiated a special prize on biodegradability – a topic of growing importance given the huge challenges involved in reducing plastic waste. Finally, Lenzing placed a recognized expert at the students’ disposal to provide assistance and answer questions: Michaela Kogler, Project Manager Nonwovens & Technical Products.

Teaming up with rainworms

Two teams were tasked with biodegrading different fibers – just like those used to produce textiles and nonwovens – with the active participation of worms. Students at BRG solarCity in Linz buried fiber nonwovens, a basic material used in wet wipes and other products, in soil that was populated with numerous rainworms, while students at Vöcklabruck Junior High School for Sports and Integration layered textiles into a vermicomposting bin. Both experiments intended to determine the extent to which certain materials would biodegrade quickly. As it turned out, both projects showed that wood-based fibers, like those that Lenzing manufactures for the textile and nonwoven industry, break down very rapidly into natural constituents that swiftly pass into the soil. In contrast, fossil-based plastics such as polyester or polyethylene cannot be decomposed by worms or bacteria but remain in the soil, sometimes for hundreds of years.

The prizes for this year’s competition were awarded on June 11. The competition attracted entries from no fewer than 209 schools, including 11 from outside Austria. For more information on the projects and the winners, visit www.vcoe.or.at.
