DeMythe® LDD

 

Sustainable degreasing and dehydration technology

With more than three billion raw hides and skins processed annually, the leather and protein industry is an important part of the world economy. One of the key phases in the leather and protein production process is removing fat efficiently from the animal skin.

The use of DeMythe® LDD

Traditional degreasing agents are harmful to health and the environment, but now AkzoNobel - together with our Spanish partner GRIT - have developed a degreasing and dehydration technology, based on the solvent Dimethyl Ether (DME). The result is a sustainable technology called DeMythe® LDD that delivers top-of-the-range degreasing and dehydration power in a closed loop process. DeMythe® LDD uses DME as an extraction solvent because of its outstanding properties as a water and fat solvent. Moreover, DME can be used as extraction solvent in the production of foodstuffs and food ingredients under EU Directive 2009/32/EC. It´s precisely these unique capabilities that gave us and our partner GRIT the scope to be able to develop a technology that will remove water and fat from animal skins and hides in a closed loop process and operating at relatively low temperatures. After the process cycle has been completed, the DME is separated from the water and fat, and then recycled. The recovery rate is >99%. In other words, low waste, high degreasing and drying performance, low energy consumption, high product quality and high cost efficiency. Hence, it contributes to a better environment.
