lAluminum has excellent recycling properties. It can be recycled and re-used repeatedly without diminishing its functionality. Recycling aluminum is environmentally friendly, requiring less than 5% of the resources required for the processing of primary aluminum, resulting in a shorter production process, less air pollution, and less production waste. Looking at aluminum from various standpoints be it resource, environmental, societal, or economic, the recycling of aluminum provides undeniable benefits that will last through generations.
lIn our quest for excellence, we invested USD$38 million in the Bao-Shan District of Shanghai in 2002 to build the largest aluminum alloy and zinc alloy die-casting facilities in China, with an annual capacity of 300,000 metric tons. With industrial ecology in mind, we adopted the most advanced equipment and technology. This has allowed us to improve product quality while minimizing, even eliminating the pollution from the aluminum recycling process. So a resort-style recycling facility surpassing any international standards was born in China, and designated Model Enterprise for the Circular Economy by Chinas National Development and Reform Commission.
The Sigma Group will take advantage of the worlds most exciting market of China and its vast untapped aluminum scrap resources. With the excellent location of Shanghai, we will promote and expand the international markets of recycled aluminum and at the same time conserve aluminum resources, and devote ourselves to the growth and development of the aluminum industry.
l The Sigma Group, established in 1978, with nearly 30 years of history behind it, continues to devote itself to the recycling of natural resources and the preservation of the environment. No matter how the world may change, the Sigma Group will always diligently adhere to its principles of sincerity and honesty, conservation, and environmental protection. The Sigma Group will always continue in its endeavors to innovate in order to protect the Earths future, and provide benefits for society and the human race.
