At the Zero Emission Farm we have – as with all other farms – organic waste such as twigs. What can this be used for in a kilma-friendly way?
Together with researchers at Norwegian Geotechnical Institute (NGI) we have produced biochar by burning dry and wet twigs and straw in pits with little access to air. The aim of the experiment has been to show that dry raw material produces little emission of methane gases during pyrolysis in an open pit. And the results show that dry and semi-dry twigs produce low emissions! Hurray!
See more about the experiment in this film:
The experiment is led by Gerard Corneliussen and Caroline Berge Hansen at NGI with good help from Joar Leon Berg at Mære. This is one of several attempts in RESTORE, where Mære agricultural school together with SINTEF, NIBIO and NGI are looking for better ways to use the organic waste on the farm and thus reduce climate emissions.
PS! It is the first time worldwide that the "trope method" has been documented with such accurate hi-tech measuring equipment! Thank you for borrowing equipment from SINTEF.
