Alternative methods for the wool wax extraction from wool scouring wastes

Wool fibers have to Traction - Upper Extremity be properly washed out before being processed into fabrics.This scouring process generates high pollutant wastes in two forms, a liquid phase and a solid phase.Both phases contain a large amount of the grease (wool wax) generated by the animal which may be recovered and purified to obtain lanolin, a highly valued product.To evaluate the amount of grease in such wastes, Soxhlet extraction with organic solvent is the technique more widely used in laboratories worldwide as it provides a high grease recovery although it is a time and solvent consuming technique.

The present work compares alternative extraction techniques to the Soxhlet extraction (Microwave, automated Soxhlet and Supercritical Fluids) recovering 100% of Silicone Molds the grease, reducing the time of analysis, the solvent consumption and the waste generation.
