Join our rubber revolution!

Our Story – from Research to Business

Reselo started as a research project at the Wallenberg Wood Science Center(WWSC) at KTH. Our co-founder Thomas had just completed his PhD studies and was then joining WWSC as a post-doc under the supervision of Dr. Lauren McKee. Supported through a WWSC stipend, Thomas’ task was to valorise birch bark. After almost 2 years of research, Thomas had developed a process to produce a novel elastomeric biomaterial from birch bark and based on his material characterisation he approached KTH Innovation. After an initial evaluation, Gustav Notander from KTH Innovation became Thomas’ business coach providing guidance and support in market research, business development and IP questions.

In 2020, Gustav encouraged Thomas to join the Start-up Climate Action Challenge initiated by Norrsken and Sting to get feedback on this business idea. There Thomas met Josefin, Henrik and Alex and together they formed the Greener Materials team. Encourage by the positive feedback from Sting and Norrsken they decided to found Reselo in January 2021 with the vision to transform todays fossil-centred industry into a sustainable bioeconomy.

In March 2021, Reselo received their first funding from Vinnova which was followed by being recognised on the IVA’s 100 list and winning the Venture Cup start-up competition as well as joining the Sting Incubate Deeptech program in the same year. So far, the team had managed to demonstrate scalability and commercial feasibility of their production process and received overwhelming interest from customers. In addition, their patent application was evaluated positively by the Swedish patent office which found no competing commercial technology.

In 2022, we sold the first kg of our bioelastomer, named Reselo Rubber demonstrating customer demand and generating first revenue. In collaboration with the Swedish Environmental Research Institute, we could show that our Reselo Rubber has a much lower carbon footprint than commonly used fossil-based rubbers thus allowing us to quantify the positive impact of our technology. In the same year, Reselo was also able to secure funding from the Swedish Energy Agency to support process development and scale-up activities. To strengthen their network within the forestry industry and advance building their business, Reselo joined the BizMaker Forest Accelerator program.

Now, we are working hard to implement our material into customer products and we are looking for investors that want to be part of this sustainable rubber revolution!
