A Comprehensive Guide to Balancing Environmental Compliance and Economic Efficiency in Solar Industry
Executive Summary
The photovoltaic industry is undergoing a critical transformation from scale expansion to high-quality development. In this context, waste gas treatment should no longer be viewed as merely an environmental cost item, but redefined as an integral component of enterprise core competitiveness. This comprehensive analysis presents a systematic waste gas treatment value reconstruction strategy based on in-depth research of the latest technological developments and regulatory trends in the industry.
New Challenges and Coexisting Opportunities in PV Waste Gas Treatment
1.1 Complexity Challenges from Technological Upgrades
With the industrial advancement of advanced cell technologies such as PERC, HJT, and TOPCon, waste gas compositions in production processes have become increasingly complex. Particularly in heterojunction cell manufacturing, the use of special gases such as silane (SiH?) and ammonia (NH?) poses higher requirements for traditional treatment processes.
1.2 Continuous Upgrade of Regulatory Standards
The "14th Five-Year Plan for Energy Conservation and Emission Reduction" explicitly states that volatile organic compounds (VOCs) emissions in key industries should decrease by more than 10% by 2025 compared to 2020. Meanwhile, local governments are implementing stricter emission limits.
1.3 New Opportunities Under Carbon Trading Mechanisms
The launch of the national carbon emission trading market has created new value realization pathways for waste gas treatment. Companies can not only reduce direct emissions through optimized waste gas treatment processes but also gain additional carbon reduction benefits through energy conservation.
