Xinjiang Tianye Co., Ltd. (新疆天业股份有限公司) is a leading Chinese chlor-alkali chemical enterprise incorporated on June 9, 1997, specializing in PVC resin, caustic soda, calcium carbide, and cement production through an integrated circular economy model. Listed on the Shanghai Stock Exchange since 1997, the company positions itself as a green modern chemical and new materials service provider, leveraging Xinjiang's abundant coal, salt, and limestone resources to produce chemical materials serving construction, infrastructure, and industrial applications.
The company operates a comprehensive "captive power → calcium carbide → PVC resin and by-products → carbide slag cement" value chain that achieves near-zero waste discharge, turning production by-products into valuable outputs and minimizing environmental impact.
Core Business Activities
Xinjiang Tianye focuses on chlor-alkali chemical research, development, and sales, operating an integrated production system that includes:
- Polyvinyl chloride (PVC) resin production (general-purpose, specialty, and paste resins)
- Caustic soda (sodium hydroxide) manufacturing via ionic membrane electrolysis
- Calcium carbide production for acetylene-based chemical synthesis
- Cement production utilizing carbide slag and other industrial waste
Business Model: Circular Economy Integration
Xinjiang Tianye operates a closed-loop industrial ecosystem:
- Captive Power Generation → supplies electricity to chemical operations
- Calcium Carbide Production → electric arc furnace using coal and limestone
- PVC Resin Manufacturing → acetylene from carbide + chlorine from electrolysis
- Caustic Soda Production → ionic membrane electrolysis of brine
- Cement Production → utilizes 100% of carbide slag waste and other by-products
- New: Ethanol-to-Ethylene Route → producing ethylene without petroleum feedstocks (via Tianye Huixiang subsidiary)
This integration achieves resource efficiency, waste minimization, and environmental compliance while creating multiple revenue streams from interconnected processes.
