Coloring of massive wood is still a major challenge in high-end wood processing, which aims to provide solid wood at a broad range of colors to furniture manufacturers. Here we report that water-saturation of supercritical carbon dioxide (scCO2)—a promising green dyeing medium—greatly improves solid wood dyeing. This has been demonstrated for disperse blue 134 and three European hardwood ...

Supercritical, carbon dioxide (,CO 2,) extraction is a processing technique whereby ,CO 2, is pressurized under carefully controlled temperatures to enable extraction of terpenes, cannabinoids and other plant molecules. Once the extract is obtained the crude is often subjected to an ethanol winterization process to remove chlorophyll, fats and waxes.

Super/subcritical ,fluid, extraction (SFE) mainly uses supercritical carbon dioxide as an extraction solvent. The best conditions were: 30% ethanol in SF at 200 bar and 60°C. The main advantage of SFE compared to the other extraction methods is the ,use, of low temperatures that prevents degradation or oxidation of specific compounds due to high temperature (Duval et al., 2016 ).
