Ecotrade Group is a leading authorized purchaser of scrap catalytic converters and over the last 15 years has built up a huge database of knowledge from which the company has developed a comprehensive catalogue that lists more than 20000 items and increasing almost daily. This online catalytic converter price book comes pictures and you can conveniently look up the value of your spent catalytic converters either by car brand or catalytic converter manufacturers. Being at the forefront of the catalyst recycling industry, we commit to provide you with the most complete and comprehensive catalytic converter catalog prices updated 3 times per day to reflect market prices. Ecotrade has invested heavily in cutting edge technology that is designed, in conjunction with laboratory analysis, to precisely measure, to an extremely high level of accuracy, the precious metal content in any single used catalytic converter. Our custom-designed fully equipped laboratories can quickly and efficiently carry out materials analysis, using several methods including X-Ray Fluorescence (XRF) testing. In scrap catalytic converter transactions, the relationship between buyers and sellers is fundamentally unbalanced. Buyers invariably have all the power; thus, for sellers, it means selling their used catalysts can be an unpleasant process. By providing quick and easy scrap cat appraisals that quickly let sellers know whether they’re getting a fair deal or not, Ecotrade Group levels the playing field and improves sellers’ negotiating positions. Also, depending on your location in the world, if you want to sell your catalytic converters, our experienced and conscientious purchasers can personally visit premises to sort and assess the worth of your material.
