The Infinex Group is the interplay of minds and decades of expertise
The Infinex Group is made up of companies operating exclusively in the field of plastics processing – from producing semi-finished goods to recycling in the form of granules and compounds that can be put to good use. It operates as an independent group of companies under the direction of its owners, the Hartl family. Haiterbach in the Black Forest is home to this second-generation family of entrepreneurs and has been the headquarters of the Infinex Group’s production and development activities from the outset. Both the group of companies and the regions where the various sites are located have shown themselves to be economically successful and resilient. This is one of the reasons why staff from over 19 different countries choose to stay for so many years. Their expertise, skills and international diversity make them a vital cornerstone of Infinex.
By pooling expertise in plastics technology and plastics recycling from a number of different companies, the group aims to offer even more flexible, sustainable and customised solutions, so as to meet the growing challenges on national and international markets. An intelligent combination of people and machines optimises workflows and production processes, while also making it possible to act and react faster. Thanks to good instincts, stable continuity and reliable expertise, staff can focus their full attention on what customers need and respond to these requirements.
As the group of companies grows, production and storage facilities naturally also need to expand. Today we can serve customers the world over – not just from our German facilities located in Haiterbach and Gera, but also from the Czech Republic and North America, thereby ensuring faster and more flexible production and delivery times.

These technical improvements make ISO-DRAIN nature 40 P 2.0 the ideal solution for applications such as intensive green roofing, retention roofs (blue roofs) and sustainable rainwater management on green roofs.

At a time when the effects of climate change are increasingly making themselves felt and our planet’s resources are becoming ever scarcer, it is more important than ever that we all take responsibility and opt for sustainable measures.
Using recycled polypropylene (recycled PP) offers an effective way of reducing our ecological footprint and making a positive contribution towards protecting the environment. Use of recycled plastic enables us to not only reduce waste and conserve resources, but also cut our CO2 emissions, thus minimising our impact on the environment. By opting for recycled PP, we are demonstrating our commitment to a circular economy and resource-friendly production.
Each and every one of us can play a part in preserving our planet for future generations – so let’s seize the opportunity to use recycled materials and together take advantage of environmentally responsible solutions. It’s time to take action and press ahead with the transformation to a sustainable future.
Together, we can shape the future!
