Prevex
Plastic-free packaging and phase-out of lead
2025 was something of a milestone for Prevex as the company turned 70. We celebrated this with a much appreciated party for all personnel in November.
Much has changed in 70 years, but some things have been there since the start. The company name is the same, Prevex still manufactures plastic products, and most of the production is still in Nykarleby, Finland. However, where Prevex manufactured all kinds of plastic products in the past, we now have one niche product – sustainable water traps.
Prevex water traps are not only physically durable but also environmentally sustainable. A few years ago, we started using recycled plastic as a raw material in all our water traps and our long-term goal is to gradually increase the proportion from the current 60 percent. To increase the proportion in the future, we performed a great deal of tests in 2025.
Sustainability is a win-win situation for both the environment and business
Our sustainability work took great strides forwards in other areas as well. We launched plastic-free packaging made of cardboard and paper and built a new production line for cardboard packaging. Furthermore, we worked hard to phase out lead from our products, resulting in brass (which includes lead) now having been almost completely replaced by other materials such as technical plastic and stainless steel.
At Prevex, we see sustainability as a win-win situation for both the environment and business. Although the stagnation in the construction industry continued in 2025, we managed to increase our revenues – largely thanks to our sustainability efforts. We have managed to find customers who appreciate high-quality, sustainable water traps.
Our sustainability work also includes social aspects. I am very pleased that our employee surveys show that we have succeeded in our goal of creating a workplace where people thrive and where collegial cohesion is strong. During the year, we also worked to improve the introduction process for new employees. And because we want to assume social responsibility, we offer people with limited working capacity the opportunity to work with us.
Another important event in 2025 was that we finished moving the last part of the assembly to Jakobstad, making us more flexible and resilient in the future. Last but not least, I am proud to say that we were able to implement the ISO 45001 management system for the work environment. We had already been working on this type of issue for a long time, and it feels good to have now received official recognition for this work.ther employers as well.
