about 70%. Therefore the production of secondary copper by the copper scrap etc. processors comes out to be 33924 tonnes/year as shown in following Table: 3.9. Table: 3.9- Production of Secondary Copper by Re-processors of copper Based on Registered Capacities with the CPCB, New Delhi & Recovery Percentage (Tonnes/year) Total Scrap intake Capacity Limit in Operation 40% Capacity utilisation 50% Production of Secondary Copper at 70% recovery 242 ,321 96,928 48,464 33,924 In addition to the secondary production of copper by the copper re-processors there are units which recover secondary copper along with other metals. As per the discussions in field as mentioned above that only 40% of these units are in operations and the capacity utilization by these units is about 50%. As copper is one of the metal recovered along with other metals such as zinc, nickel etc. the recovery factor of copper is taken as 30%. Based on these factors, the production of secondary copper by the processors of other non-ferrous metals and waste has been calculated. The production of secondary copper thus arrived at 31051 tonnes per year as shown in the Table: 3.10. Table: 3.10 - Production of Secondary Copper by Re-processors of Other Non- Ferrous Metal Waste based on Registered Capacities with the CPCB, New Delhi & Recovery percentage (Tonnes/Year) Total Scrap intake Capacity Units in Operation 40% Capacity Utilisation 50% Production of Copper at 30% recovery 517,515 207,006 103,503 31,051 3.4.2 Apparent Production In view of the above discussion the total secondary copper production by copper re-processors and other non-ferrous metals and waste re-processors is arrived at 64,975 tonnes/year. The production of virgin a primary copper cathodes during 2008-09 was 502,081 tonnes in comparison to 64,975 tonnes of secondary copper production which is about 13% of the primary production. Copper is among the most efficiently recycled material in global commerce, China being the leader in the scrap utilisation. It is 100 percent recyclable without any loss in performance if properly refined. As per 60
International Copper Association Ltd, 34% of global copper demand is met through recycling. A study conducted by Indian Copper Development Centre (ICDC), Kolkata for International Copper Study Group (ICSG), arrived at a figure of 35% to 49% of the scrap usage in India during the years 2000-01 to 2004-05. The study conducted in the field and based on the capacities of the reprocessors, about 13% of the secondary copper is being produced. Therefore a conservative figure of 20% of primary production is considered. Taking into consideration, the findings of ICDC and field study an average of 20% of secondary copper from scrap usage has been arrived at by adding 20% to the total copper production in Indian context. On this basis, the total apparent copper production in India has been arrived by adding 20% to the total copper cathode production. The same is given in Table: 3.11 and also shown in Figure –3.6.
