About PUHI
PUHI Oy, a Finnish climate tech company established in 2021, is commercializing a solution to convert biomass side streams into valuable products. The company was founded by cousins Tomi Pulkkinen and Elis Hirvonen. The idea originated from Pulkkinen's experience with his family's sawmill and the challenge of utilizing its wood waste. Together, they researched the potential of pyrolysis technology to address this, leading to the formation of PUHI.
Read full description
The company's core business revolves around pyrolysis, a process that thermally decomposes organic materials in the absence of oxygen. PUHI designs, builds, and operates pyrolysis factories that process wood and agricultural-based side streams, including waste materials, into biochar, renewable energy for district heating, and carbon removal credits. The firm's first industrial-scale biochar production plant is located in Hämeenlinna, Finland, within the Karanoja circular economy park. This facility received an environmental permit to process up to 20,000 tons of biomass annually and successfully produced its first biochar in March 2024.
PUHI's business model focuses on creating industrial ecosystems by integrating their pyrolysis units at the source of biomass generation, such as recycling yards and food production facilities. Revenue is generated through multiple streams: the sale of certified biochar for applications like soil improvement and stormwater filtration, the supply of district heating, and the sale of Biochar Carbon Removal (BCR) credits to organizations aiming to meet climate targets. The company expressly does not sell its biochar for fuel, ensuring it acts as a long-term carbon sink. PUHI has secured a total of €900,000 in funding from its founders, Business Finland, and StartUp Fund Joensuu to scale its operations.
