Circular polyamide 6 from Envalior cuts the carbon footprint of Vimar Linea switches by 80%

Vimar SpA, an Italian global company specializing in sustainable electrical wiring devices and smart home solutions, based in Marostica, Italy, has launched Linea, a new wiring devices series that lowers environmental impact while maintaining stylish design and state-of-the-art technology. 


The mounting frames for the switches are injection molded with Envalior's highly reinforced Durethan® Blue BKV60H2.0EF, a sustainable polyamide 6 that consists of around 90% circular raw materials. This compound, together with optimized production processes, improved product management, and the use of sustainably certified packaging materials, has been a key driver for Vimar in reducing the carbon footprint of the switch series by over 80% compared to previous fossil-based solutions. This translates into an annual reduction of 500 tons of CO₂ emissions.


"We are very pleased that Linea is making a major contribution to climate and resource protection. Sustainable construction materials such as Envalior’s circular Durethan® are an important element in our corporate strategy of aligning all our processes and products with the circular economy through the use of green energy, sustainable raw material management, and highly efficient technologies," explains Sandro Bernardi, Industrial Operations Director at Vimar.


Recycled fibers enhance sustainability

More than 97% of the Linea production consists of plastics from renewable and recycled sources that are mass-balanced and certified according to the ISCC Plus standard (International Sustainability and Carbon Certification). The sustainable origin of the raw materials is certified according to ISCC Plus, as are Envalior's associated production facilities in Antwerp and Krefeld-Uerdingen.


The sustainable Durethan® BLUE is reinforced with 60% recycled fibers by weight, in the production of which a large proportion of the inorganic glass raw materials is substituted by industrial glass waste. In addition, cyclohexane, which is bio-based, recycled bio-based, and/or produced by chemical recycling, is used in the production of the starting material for the polyamide 6.


"As a result, our high-performance compound consists of around 90% sustainable raw materials, which is a peak value for a glass fiber-reinforced plastic," explains Fabio Passeri, Business Development Manager at Envalior.

Easy-flowing and low warpage enable slim, durable design

Despite its high glass fiber content, the high-performance compound is so easy-flowing that it reproduces the delicate, flat geometry of the mounting frames. In addition, the construction material is low-warp and exhibits high stiffness and strength.


"The frames can therefore be made very thin-walled, which contributes to the attractive slim design of the switches. The compound's excellent electrical properties, such as high-volume resistance and high dielectric strength, combined with its long-term thermal stability ensure a long product life cycle for the switches," says Passeri.

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...

Today's KNOWLEDGE Share : What Is Going Wrong in UK Plastics Recycling?

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Borealis’ new compounding line in Belgium offers premium recyclate-based polyolefins

Image
 Borealis is proud to announce that its new compounding line for recyclate-based polyolefins (rPO) is now fully operational in Beringen, Belgium. This milestone marks a significant step forward in helping customers meet their circularity and sustainability targets—without sacrificing performance and reliability. Using Borealis’ proprietary Borcycle M mechanical recycling technology, the line combines post-consumer and virgin polyolefins into rigid polypropylene (PP) and polyethylene (PE) compounds that meet the high standards required for demanding applications in mobility, consumer products, appliances, and energy. The Beringen facility is not only designed to process a wide range of recyclate flakes, offering exceptional versatility to meet diverse customer needs, but it also serves as a platform for collaboration—enabling customers to co-develop and test new solutions that bring recycled plastics into high-value applications. “This installation is more than just a technological ...
