Description

Established in 1922, Freres Engineered Wood produces finished plywood products, lumber, veneers, structural composite lumber, and mass ply panels (MPP) with around 450 employees in Lyons, Oregon, on the westside of the Cascade Mountains. In our continuous goal of minimizing the impact we have on the environment, we have developed a high-quality biochar from our own biomass power production. To manufacture engineered wood-based products we need to produce steam and electricity. We use a 100% biomass-fired rotary bed boiler that runs 24/7. The boiler is fed with a wide range of biomass feedstocks sourced from the local region and waste from our on-site production of timber products. The process results in biochar that removes 2.899 tonnes of CO2 for every tonne of biochar. The production of biochar by Freres Engineered Wood is performed in accordance with the eligibility requirements for the Puro.earth Biochar Methodology. The feedstock comes from multiple sources: 62% of the feedstock is waste wood such as pallet grindings, ply trim and sawdust. 10% is agricultural waste, 0,3% is food processing residues, and 28% forestry residues (Bark) from Freres’ own operations. The carbon content of the biochar is 81,1% in the dry state. The stability of the carbon content can be ascertained using the molar O/Corg ratio. The maximum oxygen content was calculated by excluding other elements, and the maximum molar O/C ratio of 0.09 determined.
