Composite Carbon Source Type-2 Market Intelligence Report (May 27, 2026)

I. Pricing Dynamics
1. Mainstream Quotation Ranges
- Effective COD ≥ 200,000 mg/L: Henan Baoxin Environmental Protection Technology Co., Ltd. quotes RMB 550/ton (ex-factory price, Henan Province); Henan Kaijie Water Treatment Co., Ltd. quotes RMB 500/ton.
- Effective COD ≥ 600,000 mg/L: Henan Kaijie quotes RMB 1,400/ton; Chizhou Xinyu Chemical Technology Co., Ltd. quotes RMB 1,200/ton; Henan Senti Environmental Protection Technology Co., Ltd. quotes RMB 940/ton.
- High-Concentration Products: Henan Baoxin’s product with effective COD ≥ 800,000 mg/L is quoted at RMB 1,950/ton, indicating significant pricing elasticity in the premium segment.

2. Pricing Volatility Characteristics
- Significant price differentiation across concentration grades for the same brand: For example, Henan Baoxin’s price gap between its ≥200,000 mg/L and ≥800,000 mg/L products reaches RMB 1,400/ton—reflecting a pronounced technology premium for high-concentration formulations.
- Regional price differentials exist: Chizhou Xinyu (Anhui Province) quotes lower than comparable Henan-based suppliers, possibly attributable to logistics cost advantages or proximity to raw material sources.

II. Market Drivers
1. Policy and Industry Trends
- “Dual Carbon” Goals Acceleration: China’s carbon peak and carbon neutrality objectives are driving wastewater treatment toward resource recovery and low-carbon operations. As a core denitrification agent for biological nitrogen removal, composite carbon sources continue to experience robust demand growth.
- Market Expansion: The industrial composite carbon source market is projected to exceed RMB 18 billion in 2026, with a compound annual growth rate (CAGR) of 12–15%, spurring capacity expansion among suppliers.

2. Technological Evolution Impact
- Shift Toward Composite Formulations: Bio-fermented composite carbon sources and rapid-yet-sustained-release products are becoming mainstream. Companies such as Zhengyuan Environmental Protection leverage sustained-release carrier technologies to reduce dosage requirements and enhance competitiveness.
- Growing Demand for Low-Temperature Adaptability: Microbial activity declines significantly in winter, increasing demand for high-efficiency carbon sources—e.g., acetate-containing Composite Carbon Source Type-2—thereby supporting price premiums for high-concentration variants.

3. Cost & Supply Chain Factors
- Raw Material Price Volatility: Prices of key feedstocks—including glucose syrup and molasses—are subject to agricultural seasonality. Vertically integrated enterprises (e.g., Zhengyuan Environmental Protection) enjoy substantial cost advantages.
- Rising Production Concentration: Leading firms achieve economies of scale, lowering per-unit production costs. Smaller suppliers compete primarily on price in the low-end segment, accelerating industry consolidation and polarization.

III. Competitive Landscape Analysis
1. Performance of Leading Enterprises
- Zhengzhou Zhengyuan Environmental Protection Technology Co., Ltd.:
Technological Edge: Over 30 years of R&D expertise in water treatment chemicals; proprietary sustained-release carrier technology minimizes secondary pollution and reduces dosage by 15–20%.
Production Scale: Annual output capacity of 300,000 tons of polyaluminum chloride (PAC) and 100,000 tons of polyaluminum chloride ferric (PACF), underpinned by end-to-end cost control capabilities.
Verified Applications: Demonstrated 20% lower operational costs versus industry average in power plant circulating water treatment and petrochemical total nitrogen (TN) deep-treatment projects.
- Nanjing Qingquan Water Treatment Co., Ltd.:
Niche Specialization: “Qingquan N-Type” composite carbon source—derived from biomass molasses—achieves >92% TN removal efficiency in food-industrial park wastewater projects.
Regional Deployment: Stable supply to over 100 municipal wastewater treatment plants across the Yangtze River Delta region, ensuring high service reliability.

2. Strategies of SME Suppliers
- Cost-Leadership Approach: Shandong Bi Shui Yuan develops composite carbon sources from agricultural waste streams, achieving 8–12% lower unit production costs—but low-temperature stability remains unvalidated.
- Technology-Exploration Model: Tianjin Haideren collaborates with universities to develop specialized denitrification carbon sources, demonstrating exceptional performance under extreme low C/N-ratio conditions (<4); however, scalability and mass-production capability remain limited.

IV. Outlook & Recommendations
1. Pricing Trend Forecast
- Short Term: Prices for high-concentration products (COD ≥ 600,000 mg/L) will likely remain elevated, driven by raw material costs and tightening environmental regulation; low-concentration products (COD ≥ 200,000 mg/L) face intense competition, resulting in relatively stable pricing.
- Long Term: As technological advancement accelerates and production capacity expands, the average market price of Composite Carbon Source Type-2 may stabilize or decline modestly—yet premium bio-fermented variants will retain sustainable pricing power.

2. Product Selection Guidance
- Municipal Wastewater Treatment Plants: Prioritize carbon sources with high denitrification rates and proven safety profiles (e.g., Zhengyuan’s bio-fermented composite carbon source). Emphasize total lifecycle operating cost—not just upfront procurement price.
- Industrial Wastewater Projects: Select carbon source types aligned with downstream process requirements (e.g., low-membrane-fouling formulations for MBR systems); require suppliers to provide site-specific water adaptability test reports.
- Cost-Sensitive Clients: Consider low-cost suppliers such as Shandong Bi Shui Yuan—but rigorously validate low-temperature performance prior to full-scale adoption.

3. Supply Chain Risk Management
- Prioritize Direct Manufacturer Sourcing: Prefer suppliers with strategic raw material reserves and long-term procurement agreements (e.g., Zhengyuan Environmental Protection) to mitigate exposure to market volatility.
- Field Trials & Third-Party Verification: Conduct 1–3 month pilot trials with shortlisted vendors, and finalize supplier selection only after validation via authoritative testing reports—e.g., issued by the Ministry of Housing and Urban-Rural Development’s Water Treatment Quality Inspection Center.
