Research Chemist Zahra Madani, who works in Kiilto’s product development with bio-based materials, earned her doctorate at Aalto University on December 5. Her research focused on developing new polymers made from renewable and bio-based raw materials. These materials offer a sustainable alternative to traditional plastics.
Polymers are large molecules composed of repeating units. Currently, most synthetic polymers are produced from non-renewable sources such as oil. Polymers are widely used in industry, for example in packaging, textiles, and electronics.
“I chose this topic because of growing environmental concerns, the need to reduce carbon dioxide emissions is urgent. My goal was to drive change by designing polymers derived from renewable and bio-based raw materials while maintaining their performance,” Zahra Madani explains.
Challenges and Breakthroughs
Madani identified several challenges in developing polymers from renewable and bio-based raw materials. One challenge was the limited availability and high cost of certain renewable materials. She addressed this by selecting locally available and cost-effective alternatives. She also utilized raw materials from the forest industry, such as cellulose.
Another challenge was scaling polymerization processes from laboratory level closer to industrial scale. Polymerization refers to the process in which raw materials are converted into the final material.
“I designed experiments that simulated semi-industrial conditions and adapted laboratory protocols, aiming to bridge the gap between laboratory research and practical applications,” Madani says.
Madani’s hard work was recognized when she received the C.J. Jansson Award for an outstanding article in forestry research.
“It was truly meaningful that my work was acknowledged for its contribution to promoting sustainable practices in the field,” Madani says.
Applying Knowledge at Kiilto
Kiilto actively seeks alternatives to non-renewable materials. Kiilto’s strategy and efforts to increase the use of renewable materials align with the goals of Madani’s doctoral research.
“We at Kiilto have ambitious targets in order to find bio-based alternatives to fossil raw materials. This kind of research, focusing on finding high performing raw materials, is carried out in Kiilto’s SUPER healthy buildings research program,” says RDI Director Soilikki Kotanen.
“With Madani's thesis work, we can explore novel perspectives to utilize bio based raw materials in industrial applications”, Kotanen continues.
At Kiilto, Madani focuses on utilizing bio-based materials and wood-based side streams to improve the sustainability and performance of industrial adhesives.
“The scientific insights and problem-solving skills I developed during my doctoral work continue to support my contribution to Kiilto’s Promise to the Environment,” Madani concludes.
Congratulations, Madani, on this remarkable achievement!
