Finnish MPs and experts of forest bioeconomy chose the winning entry in the 2023 Uusi Puu – New Wood competition: it is the biochar developed by GRK Suomi Oy and Carbon Balance Finland Oy.
According to GRK Suomi Oy, the biochar has dozens of uses, in landscaping, water treatment and purification and in soil improvement, to name a few.
’A brilliant and functional invention,’ was the verdict of the competition jury.
The aspects sought for in the competition were an inventive use of wood and the capability to respond to global challenges. Biochar contributes to combating climate change: according to the manufacturer, one metric ton of biochar binds about three tons of carbon dioxide.
“Biochar represents an extremely interesting, systemic-level possibility to contribute to soil improvement and the sensible use of biomass,” noted the jury.
Biochar is produced from plant-based biomass, generally wood, by pyrolysis, also known as devolatilization. In addition to wood, biochar can be made from hemp, willow, reed canary grass, slurry and dung, as well as household bio and garden waste.
“Biochar is a brilliant innovation because so many different side streams can be used to make it,” said Virpi Korhonen, Project Manager of the Uusi Puu – New Wood competition.
