Our Story
Since our company was founded more than 30 years ago, our main strategic goal has never changed: creating a more sustainable environment by turning waste into raw materials.
From Waste to Raw Material
In 1990, after spending several years in the chemical trade, Helena and Winfried Friedel founded their own company in the basement of their house with a simple idea: turning waste into raw materials.
While sustainability is on everybody’s mind in today’s world, back in the day it was a unique idea. Chemical companies were focusing their attention on finished products and neglected the opportunities that come with side streams and waste materials. Given the fact that some of these materials were toxic, hazardous or/and pollutant, the cost of disposal was quite staggering.
Thanks to their chemical expertise and extensive network in the industry, they developed new applications for these materials and gave them a second life. 30 years later, the roots of our heritage are the key drivers of our aspirations for creating a more sustainable environment.
More than a distributor
We are a problem solver with in-depth knowledge of our suppliers' products, side streams and production processes. On this basis, our well-trained technical team finds creative solutions to challenges of all kinds. Our extensive network and partnerships help us explore the latest treatment options such as distillation, depolymerization, and mechanical and chemical recycling.
Taking these resources into account, we develop comprehensive waste management concepts that cover the entire supply chain, including packaging, storage, transportation, notification, customs clearance, REACH and safety protocols. Our goal is to provide the best solutions by taking care of everything around our customers' core business.
"Together, we grow stronger."
We are striving for closed loops, circular economy, and decarbonization. With our knowledge and experience, we support the chemical industry in its transformation to a more sustainable future by recovering, reusing and recycling secondary products, industrial waste streams, off-spec materials, and by-products – our WISTEMA DNA.
For more than 30 years, we have been diversifying our product portfolio and increasing our international reach. Today, we offer our customized services in more than 60 countries.
Our success is rooted in the passion and dedication of our employees to develop creative solutions to complex challenges. Read our story to learn more about our roots.
