## About

Based in Tallinn, Estonia, and founded in 2019, UP Catalyst OU operates as a nanotechnology research company that produces carbon nanomaterials and graphite materials for batteries from waste CO2 using flue gases from heavy industry emitters as a feedstock. The company was Co-founded by Einer Karu (CTO), Katlin Kaare, and Ivar Kruusenberg. In April 2022, UP Catalyst OÜ raised EUR 500,000 in pre-seed funding led by Sunly, Little Green Fund, Scottish Baltic Invest, and UniTartu Ventures.

The green technology firm converts carbon dioxide into nanomaterials and graphite products which are used in electric car batteries, concrete, and biomedicine. The firm develops batteries and supercapacitors from carbon nanomaterials. It offers nanomaterials for paints and coatings as it improves electrical conductivity and mechanical strength. The products offered by the firm include carbon nanofibers, carbon black, multiwalled carbon nanotubes, and graphene-like carbon along with graphite and hard carbon.
