About
Hjelmsäters Egendom is a centuries-old Swedish agricultural estate in Hällekis (Kinnekulle), owned by the Hamilton family since the early 1700s, which operates a pyrolysis unit producing EBC-certified biochar from forestry residues for soil amendment. They sell biochar under the biokol.se brand, resell Brachio Solutions biochar boilers in Sweden, and have registered as a supplier on Puro.earth. Biochar is an adjacent add-on activity to the estate’s core agriculture/forestry business.
