Germany in provisional exercise, the Scholz government is in chaos over the budget and the economy is doing badly
In the midst of a provisional exercise, Germany finds itself ensnared in a tumultuous scenario under Chancellor Olaf Scholz’s leadership. Promising no cuts to the welfare state amidst plummeting poll numbers, over half of Germans contemplate early elections alongside European ones, as the current legislature, scheduled until autumn 2025, navigates a deep crisis, particularly with the budget. Smart textile
Historically, Germany’s budget prowess, a stronghold during the Merkel era, now teeters, turning Berlin into the subject of European mockery. The Constitutional Court’s rejection of a 60-billion-euro expedient in November escalated the chaos, revealing 29 special vehicles with 869 billion against the Charter, leading to a freeze on spending by Finance Minister Christian Lindner, except for defense and parliament.
The looming specter of starting 2024 in provisional operation, where only essential expenses are permitted, underscores the critical impasse. With 17 billion yet to be covered, the “traffic light” majority, comprising the Social Democratic Party, the Greens, and the Liberals, grapples to reach a consensus on where to make cuts.
As the economic indicators reflect a dire situation—with manufacturing PMI below 50 points for over a year and a half and negative GDP growth—the political disarray is exacerbated by the rising popularity of the AfD, a conservative right-wing party accused of being “neo-Nazi.” Smart textile
The potential influence of the AfD adds a layer of complexity to an already precarious political landscape, raising questions about the endurance of Germany’s established order. The nation, once an economic and political stalwart, now grapples with uncertainties that reverberate beyond its borders.
Puma expands fibre-to-fibre recycling
Puma is intensifying its commitment to sustainable practices by expanding its Re:Fibre polyester recycling technology. The sports brand aims to derive 100% of its polyester from textile waste, shifting away from PET fibers sourced from bottles. Starting in 2024, the majority of Puma’s replica football jerseys will feature fibers crafted from old garments and factory waste instead of recycled PET bottles. Smart textile
The Re:Fibre pilot, initiated in 2022, has already been employed to produce replica kits for the Women’s World Cup and Girona’s 2023/24 season third kit. In 2024, the official Puma football replica jerseys, including those for the Euro and Copa América tournaments, will adopt the Re:Fibre technology. The program involves collecting, sorting, and processing textile waste through a chemical recycling process, ultimately producing new Re:Fibre fabrics.
Anne-Laure Descours, Chief Sourcing Officer at Puma, emphasizes the brand’s ambition for a complete transition to polyester sourced from textile waste, addressing the environmental risk posed by textile waste accumulation in landfills. Puma recognizes the need to rethink production methods, embracing a circular business model as a key element of its sustainability strategy. Smart textile

Smart textile fiber places conductivity and flexibility side-by-side
Electrically conductive “smart fabrics” have many potential applications, but their specialized fibers typically aren’t as soft and flexible as those made of regular materials. An experimental new two-faced fiber, however, is both flexible and conductive.
Developed by a team of scientists at Washington State University, the fiber is made of two substances: cotton cellulose obtained from recycled T-shirts, and an existing conductive synthetic polymer known as polyaniline. Smart textile
The polyaniline is combined with the cotton cellulose because it’s too brittle to be formed into usable fibers on its own. That said, the two materials aren’t simply blended into one homogenous mixture. If they were, the polyaniline would be diluted to the point that it would lose its conductivity.
Instead, liquid solutions of the two substances are extruded from two separate (but closely spaced) nozzles, merging and bonding to form a single fiber which is cotton cellulose on one side and polyaniline on the other. Smart textile
In lab tests, such fibers have exhibited excellent electrical conductivity while also offering the strength and flexibility of cotton. They have also been successfully used in textile systems that delivered power to an LED light, and that sensed ammonia gas.
The objective is to comprehend the processes of degradation and biodegradation for the purpose of devising technical solutions to environmental challenges
Michelin, the renowned French tire manufacturer, joined forces with Clermont Auvergne University and the Center National de la Recherche Scientifique (CNRS) to delve into the wear degradation of tires. This involves the consequential formation of microparticles and the subsequent study of the biodegradation mechanisms associated with these microparticles. Smart textile
Establishing the BioDLab, a dedicated laboratory, is a pivotal step in this collaborative venture. The primary mission of BioDLab is to scrutinize the underlying causes of tire wear degradation and develop technical interventions for environmental predicaments. One of the focal points is exploring methods to render wear particles biodegradable in the environment.
Tire erosion, an inevitable consequence of contact with road surfaces, is essential for ensuring vehicle safety and traction. Tires, alongside fabrics, are identified as primary contributors to the creation and dissemination of microplastics in the environment, with rubber being the specific material of concern. Smart textile
Over the span of four years, the project will systematically investigate the chemical phenomena associated with microparticle degradation under the influence of solar energy and water. This interdisciplinary approach combines material science, chemistry, and microbiology to unravel the intricate regulatory mechanisms of this process.
The research specifically targets the degradation of rubber used in tires, employing photochemical and thermochemical processes, as well as exploring biodegradation facilitated by microorganisms and enzymes. Approximately twenty researchers from the Clermont-Ferrand Chemistry Institute (University of Clermont Auvergne/CNRS) and ten technicians from Michelin’s Operational Research and Development Department will be actively engaged in this collaborative effort.
