Extraction of cones, branches, needles and bark from Norway spruce (Picea abies) by supercritical carbon dioxide and soxhlet extractions techniques

•Waste fractions: cones, bark, needles and branches valorized by extraction•The fractions yielded valuable organic compounds such as sterols and nonacosanol•Supercritical CO2 extraction was established as a green method for lipid recovery•Economic analysis of scCO2 extraction of Norway Spruce waste fractions•Differences between soxhlet and scCO2 methods as a function of chemicals reported
