Waste Gas Treatment News From 2026.02.26-2026.03.01

This report focuses on core news in the waste gas treatment field, covering four dimensions: policy standards, industry governance, monitoring technology, and market impact. It precisely covers industrial waste gas (including VOCs), ultra-low emissions, and process supervision, adapting to equipment manufacturing, engineering services, and overseas business scenarios.

I. Core Policy Standards (Mandatory Implementation, Directly Driving Equipment Upgrades)

1. New Version of the Ambient Air Quality Standard (GB 3095—2026)

Implementation Time: From March 1, 2026 (including a transition period until the end of 2030).

Key Tightening: PM2.5 annual average 25μg/m³, daily average 50μg/m³ (previously 35/75); simultaneously tightening limits for PM10, SO₂, and NO₂.

Impact of Waste Gas Treatment: Forces deep reductions in NOₓ, SO₂, and VOCs (PM2.5 precursors), leading to a surge in demand for ultra-low emission retrofitting in industries such as steel, coking, cement, petrochemicals, and coating. Transitional Arrangements: Transitional limits (annual average PM2.5 30, daily average 60) will be implemented from 2026 to 2030, providing a window of opportunity for enterprises to upgrade.

2. New VOCs Monitoring Standard (HJ 1458—2026)

Implementation Date: May 1, 2026 (First release, mandatory) Ministry of Ecology and Environment.

Core Content: Standardizes the determination of 30 VOCs in exhaust gas from stationary pollution sources, using gas bag sampling/portable gas chromatography-mass spectrometry (GC-MS) Ministry of Ecology and Environment.

Market Impact: Replaces existing non-standard methods, promotes the upgrading of portable VOCs monitoring equipment, strengthens enterprises' self-monitoring and enforcement traceability capabilities, and benefits the precise operation and maintenance of end-of-pipe treatment facilities such as spray towers, RTOs, and activated carbon adsorption.

3. New Regulations for Low-Concentration Particulate Matter Monitoring (HJ 1457—2026)

Implementation Date: May 1, 2026 Ministry of Ecology and Environment.

Core Content: This standard specifies portable beta-ray diffraction (β-ray method) measurement of low-concentration particulate matter in stationary pollution source exhaust gas, adapting to refined supervision after ultra-low emission standards are implemented.

Application Scenarios: Real-time verification of emission outlets after ultra-low emission retrofitting in industries such as thermal power, steel, and cement, improving data accuracy.

II. Key Industry Governance Areas (Clarifying Annual Tasks and Locking in Market Opportunities)

1. Annual Targets for the Blue Sky Protection Campaign (February 27, Ministry of Ecology and Environment)

Key Industries: Complete ultra-low emission retrofitting of 100 million tons of cement clinker and 50 million tons of coking capacity by 2026.

Rectification Directions: Investigate inefficient and ineffective exhaust gas treatment facilities (e.g., clogged spray towers, insufficient RTO combustion efficiency), and classify and rectify traditional industrial clusters (coating, printing, chemical).

Collaborative Control: Promote pilot projects for atmospheric ammonia emission control (livestock farming + industrial sources), and deepen joint prevention and control of heavy pollution weather in the Beijing-Tianjin-Hebei region and surrounding areas.

2. Emergency Emission Reduction for Heavy Air Pollution (March 1st, Hengshui and other areas activated Level II response)

Control Measures: Enterprises involved in air pollution must strictly implement the emergency emission reduction list; those not included in the list must cease all air-polluting processes; the use of non-road mobile machinery of National II emission standard and below is prohibited.

Requirements for Enterprises: Waste gas treatment facilities must have rapid start-up and shutdown capabilities and ensure compliance; records must be complete to avoid penalties for inadequate emergency emission reduction.

III. Technology and Market Trends (Digitalization + Overseas Expansion, Main Theme of Industrial Upgrading)

1. Reassessment of Industry Value (February 28th, All-China Federation of Industry and Commerce Environmental Service Industry Chamber of Commerce)

Waste Gas Treatment Direction: Digitalization and intelligentization are becoming core; AI large-scale models permeate the entire lifecycle of facility design, operation optimization, fault early warning, and carbon accounting.

Overseas Expansion Opportunities: Technology/service overseas expansion is one of the four major trends, adapting to the industrial waste gas treatment needs of "Belt and Road" countries, benefiting enterprises with English compliance documents and international certifications.

2. Accelerated Integration of Monitoring and Treatment

Core Logic: Following the implementation of HJ 1458/HJ 1457, integrated "monitoring-treatment-operation and maintenance" has become a necessity. Enterprises need to equip themselves with portable monitoring equipment and end-of-pipe treatment facilities to achieve data closure.

Technological Highlights: Online VOCs monitoring and RTO/RCO linkage control, intelligent dosing systems for spray towers, and collaborative treatment technology for low-concentration particulate matter.

IV. Compliance and Enforcement Tips (Risk Mitigation, Capability Enhancement)

Self-Monitoring Compliance: Complete the selection, calibration, and method validation of VOCs/low-concentration particulate matter monitoring equipment by May 1st to ensure compliance with HJ 1458/HJ 1457 requirements.

Records and Source Tracing: Establish an operational record book for waste gas treatment facilities (reagent consumption, temperature, pressure, emission data), retain gas bag sampling and GC-MS test reports, and prepare for enforcement source tracing.

Transitional phase preparation: In accordance with the transitional limits of GB 3095—2026, formulate emission reduction plans for NOₓ, SO₂, and VOCs, and prioritize the renovation of inefficient spray towers, activated carbon adsorption and other facilities.
