Through years of development, the company has gained significant influence within the industry. It is recognized as a National High-Tech Enterprise, a Zhejiang Provincial Industrial Circular Economy Demonstration Enterprise, and was designated by the National Development and Reform Commission as part of the second batch of National “Urban Mines” Demonstration Bases. The company operates a municipal-level enterprise R&D center. Its testing center's high-nickel matte detection system holds CNAS accreditation. It maintains a joint doctoral innovation workstation with Zhejiang University and collaborates with Zhejiang University, Jinchuan Nickel-Cobalt Research Institute, and Jiangxi University of Science and Technology. These partnerships have yielded significant achievements in smelting technology, mineral processing techniques, precious metal recovery, nickel-based alloy product development, and crystallographic phase theory research—all of which have been successfully applied in production. To date, the company has obtained 4 invention patents and 27 utility model patents.

Guided by the principles of sustainable development and circular economy, the company has established a comprehensive urban mineral resource recycling system—transforming waste into renewable resources and products—leveraging domestically leading energy-saving and environmentally friendly equipment alongside digital infrastructure. It comprehensively, standardizedly, and systematically processes and utilizes non-ferrous metal solid waste. Key products include high-nickel matte, low-nickel matte, crude copper, matte copper, and rare precious metals such as gold, silver, platinum, and palladium. With an annual processing capacity of 196,000 tons of copper and nickel hazardous waste, it stands as a benchmark enterprise for copper and nickel metal recycling in the Yangtze River Delta region.

Amid intensifying industry competition and rapid advancements in recycling technology, the company's next five-year plan focuses on recovering copper-nickel co-occurring raw materials. Leveraging its comprehensive equipment and process systems alongside accumulated foundational technical strengths, it aims to establish a model for copper-nickel resource recovery characterized by environmental benefits. Expanding raw material sourcing channels and refining material characteristics, the company adheres to the resource utilization principles of “short processes, multiple products, and low costs.” By introducing technologies such as oxygen-enriched smelting, hydrometallurgical leaching, selective refining, and rare/precious metal extraction, it extends its industrial chain. This enables the development of electrolytic nickel, battery-grade nickel sulfate, tin-zinc alloys, precious metals, and nickel-based alloy products. We will establish a closed-loop resource recycling enterprise encompassing recovery, utilization, and productization, elevate our industry standing, and become a benchmark enterprise in the specialized field of copper and nickel non-ferrous metal recycling.

Zhejiang Huanyi adheres to the principle of “people-oriented, harmonious progress,” implementing the business philosophy of “balancing environmental protection with production development, and prioritizing both social and economic benefits.” We sincerely look forward to collaborating with all sectors to jointly contribute to advancing the circular economy.
