| الوصف: | Content: A combination of processing techniques and speciality chemicals has been developed to target environmental issues and legislation in the European leather industry, especially for automotive upholstery leather. This process combines new techniques in the beamhouse process through to the tanning process. Initial work on several different individual concepts showed some excellent improvements, but when these concepts have been brought together to form a single strategic process the advantages and improvements have exceeded expectations. The process demonstrates a reduction in the use of salt, formic acid and sulphuric acid. After more than two years of trials from small scale to full production in an automotive leather production environment, we are able to present independently test results showing the benefits of following this system. Briefly these include Improvement in tear and tensile strength results. Improved clarification with less suspended solids in the supernatant. Reduced COD in the supernatant and higher biodegradability COD/BOD. Less TDS in the supernatant. Chloride content reduction in the supernatant Sludge generation reduction. Less organic residues derived from the hide. Take-Away: A simple technique and small modifications to existing processing methods will reduce dramatically the environmental effects of wet white / chrome free tanning. This process can be used in any country in the world and answers many questions regarding reducing salt, BOD, COD, TDS etc. |
