Mr. Wang Bo Yi, the Founder of Hunan Bable Material Technology Co., Ltd., leads a technology-driven enterprise pioneering energy-saving materials for the metallurgical sector. With a mission rooted in low-carbon innovation, his company’s breakthrough nanoceramic coating technology is revolutionising electrolytic aluminium production by improving efficiency, reducing emissions and promoting sustainable industrial practices globally.
In an interview for “Sustainability & Recycling: Aluminium's Dual Commitment” e-Magazine, Wang highlights Bable’s groundbreaking nanoceramic-based high-temperature antioxidation coating that significantly reduces carbon consumption and emissions in electrolytic aluminium production. It explores the company’s real-world applications, measurable results in leading aluminium enterprises and its global ambitions to drive sustainable transformation through advanced material technologies and robotic spraying innovations.
AL Circle: Please provide a brief on your contributions to sustainability initiatives across the aluminium value chain.
Mr. Wang: Our company is a technology-based enterprise integrating R&D, production, sales, energy-saving promotion and technical services of new materials for metallurgical energy conservation and consumption reduction. Determined to be an expert in energy conservation and consumption reduction in the metallurgical industry, we continuously develop new materials and technologies for the development of the industry’s energy-saving sector. Its core technology – “Nanoceramicbased High-temperature Antioxidation Coating Protection Technology for Electrolytic Aluminium Pre-baked Anodes and Anode Steel Claws” – developed relying on strong scientific research resources, is an industry pioneer. It has been included in the National Key Promoted Low-Carbon Technology Catalog (the 4th Batch) by the Ministry of Ecology and Environment, listed in the National Recommended Catalog of Energy-Saving and CarbonReducing Technology Equipment in the Industrial and Information Technology Field (2024 Edition) by the Ministry of Industry and Information Technology, and appraised as reaching the international advanced level by the China Non-Ferrous Metals Industry Association.
AL Circle: What services do you provide related to carbon capture and storage in the aluminium industry to reduce carbon footprint in the environment?
Mr. Wang: High-temperature carbon anode oxidation has long been a problem in electrolytic aluminium production, which increases costs and emissions. In Bable, our self-developed nanoceramic coating can form a dense protective layer to block the erosion of high-temperature air, CO₂ and fluorides. The effects are quite remarkable. In terms of carbon and emission reduction, it can extend the anode cycle by more than 1 day; reduce carbon consumption per tonne of aluminium by 13-16kg and CO₂ emissions by about 50kg. In terms of quality and efficiency improvement, it lowers the iron content of primary aluminium by over 200ppm, increases current efficiency by 0.3%-0.7%, and extends the service life of steel claws by more than 2.5 times. In terms of waste reduction, it cuts carbon slag and electrolyte free carbon by more than 30% respectively.
AL Circle: Has this technology been applied in the market? What are the application results, could you share with us?
Mr. Wang: Technological value lies in application. Up to now, this technology has been applied in domestic leading electrolytic aluminium enterprises such as Guangxi Hualei, Lanzhou Aluminum and Qingtongxia Aluminum, and has also been expanded to overseas markets like India, bringing both economic and environmental benefits to cooperative enterprises. For example, after adopting our technology, Guangxi Hualei reduced carbon consumption per tonne of aluminium by 13.8kg and annual CO₂ emissions by about 20,000 tonnes. Meanwhile, we also participate in the formulation of industry standards to promote replicable green development paths.
