The advantage is that it is a much milder and cleaner method than traditional curing methods.’ ‘To extract the remaining fats, we use the gas dimethyl ether (DME) and put it under intense pressure, making it a liquid. In doing so, Hulshof uses the DeMythe® technology developed by Akzo Nobel for the leather industry to remove water and fat from animal hides. This step is being taken through an innovative programme supported by EFRD grants. The next step is to extract high quality proteins, fats and oils from other animal waste material, such as pig skin, chicken skin and animal organs. Hulshof Protein Technologies has been extracting protein from the protein-rich subcutaneous tissue in cattle. These are companies that expect their suppliers to do everything possible to minimise their impact on the environment.’ Hulshof’s leather can be found in products of Spyker, Mercedes, Montis, Gucci and Louis Vuitton. ![]() Follow up tests are already being carried out to extract valuable material from skin tissue and fat as well. ‘Using waste material more efficiently is interesting from an economic perspective, but also has environmental benefits. Verstrate heads Hulshof Protein Technologies, where waste products are processed into high quality proteins. ‘Extracting fats and proteins from animal waste material is a logical consequence of the development the company is undergoing’, explains Peter Verstrate. ![]()
