Since the mid-1980s, resources scarcity and environmental degradation promote the recycling of renewable resources including cobalt and nickel in advanced industrial countries. With the implementation of relating laws and regulations, China establish principles of minimize waste generation and the polluter pays for governance obligations. The waste recycling guidelines that producers and consumers bear the responsibility for cost of recycling and recovery officially start.

In recent years, renewable nickel powder develops quickly. Its production is more than that primary nickel powder. Since 2003, the global renewable nickel powder accounted for the proportion of the total nickel supply has reached more than 30% renewable nickel raw material comes mainly from various forms of nickel-containing waste batteries, catalysts, electroplating, metallurgy, stainless steel, super alloys and other industries. At present, China produces every year containing nickel powder waste to 150,000 tons. In recent years, the recycling of waste miscellaneous nickel advantage of growth significantly, but the majority of waste recovery of miscellaneous nickel to nickel salts, nickel, iron and other primary products.

Contradiction between resource exploitation and consumption of nickel powder is increasing, and will promote the development of renewable nickel powder resource recycling. As mentioned above, the nickel powder lack of resources, but consumption is a huge supply of resources can not meet demand. The contradiction between demand and supply of nickel resources, will force China to seek new sources of supply of resources, but the only way to quickly add a new source of supply is a lot of recycling waste nickel resources. Therefore, we can foresee that, in the future, recovery industrial scale of renewable nickel powder resource will be rapid expanded.

Waste nickel powder material will cause a potential threat to the environment, in particular nickel waste harmful to the environment greatly. Nickel powder waste recycling and reuse, requires companies to have the processing capacity; the same time, to improve the level of resource utilization, the use of renewable resources to produce products to meet the quality requirements of end customers, the highest requirements of the resource is renewable resources The production of the product to reach the ore as raw materials to produce the product quality, accessible and used in downstream industries.

China is a secondary battery of the world's largest battery production and consumption from 2001 to 2005 is about 7.73 billion. According to the three-year life and each nickel cadmium, nickel metal hydride and lithium-ion battery, the average weight of 25 g, the total weight of all waste secondary batteries is about 19.3 million tons of nickel of about 32,800 tons. If all of these batteries into the nature, will result in the loss of soil function, approximately 65 billion cubic meters of water pollution, or about 27,000 square km, used batteries are not only enormous pressure on the environment, while also wasting a lot of scarce resources. Therefore, to carry out specialized recycling of used batteries and other renewable resources of nickel powder, and also the protection of the urban environment in China. It is an effective way for recovering nickel scarce resources.

Nickel powder is high value-added and high-tech products in nickel industry chain. It is a typical capital-intensive product with features of internationalization of market, quality and manufacturing. The market is mainly dominated by world-class companies. While there are few Chinese metal powder exporter which can produce ultrafine nickel powders to adapt battery industry and high-end carbide industry. Their production capacity can not meet the demands. In recent years, some Chinese companies increase R & D efforts and narrow the gap with developed countries in product quality. However, the vast majority of manufacturers have a certain gap with multinational companies on the production scale, equipment level and manufacturing technology.Source:http://www.mhcmp.com
