90 Substance flow analysis of the recycling of small WEEE management system led to the loss of 530 to 1070 kg of gold and 270 to 550 kg of palladium. Figure 19 Flows of gold and palladium contained in end-of-life cathode-ray tube monitors in the USA in 2007 1 5.4. Large high-grade equipment Regarding large high-grade equipment, which includes mainly Hi-fi units, CD players, printers, video recorder, DVD players, flat displays and laptops, a very high collection rate of around 92% is achieved in Germany (Figure 20). Around 49 000 tonnes of waste equipment belonging to this equipment group were generated in Germany in 2007, containing between 470 and 690 kg of gold and between 80 and 120 kg of palladium. Around a third of these precious metals is recovered. Figure 20 Flows of gold and palladium contained in large high-grade waste equipment in Germany in 2007 1
5. Quantification of the flows of gold and palladium 91 In the USA, the collection rate is almost 60%. Between 3 and 9 tonnes of gold were contained in the 260 000 to 740 000 tonnes of large high-grade equipment that were generated in 2007 (Figure 21). Around 17% of the precious metals are recovered. The losses have an economic value of 20 to 160 million US-dollars for gold and 2 to 16 million USdollars for palladium. The uncertainties are very large. Figure 21 Flows of gold and palladium contained in large high-grade waste equipment in the USA in 2007 1 5.5. Small high-grade equipment The generation of small high-grade waste equipment amounted to 1160 to 1700 tonnes in Germany in 2007 and contained 67 to 108 kg of gold (Figure 22). Around 54% of this equipment was collected. The management system allowed the recovery of almost 20% of the precious metals. Between 50 and 88 kg of gold and between 11 and 19 kg of palladium were discarded. Figure 22 Flows of gold and palladium contained in small high-grade waste equipment in Germany in 2007 1
