China’s New Ecological Code Sets Sub‑10mg/m³ Dust Limit

Why the Ecological Environment Code, effective August 15, 2026, represents a fundamental shift for sand and aggregate operations – and what it means for quarry operators and equipment buyers worldwide

On August 15, 2026, China’s Ecological Environment Code officially took effect. As the country’s second law to be formally titled a “Code” after the Civil Code, it consolidates 10 separate environmental laws – including the Environmental Protection Law, Air Pollution Prevention Law, Water Pollution Prevention Law, Soil Pollution Prevention Law, and Solid Waste Pollution Prevention Law – into a single, unified framework spanning 5 parts and 1,242 articles. For the sand and aggregate industry, which serves as the core supporting sector for resource development and infrastructure construction, this landmark legislation establishes full life‑cycle compliance requirements covering extraction, processing, and transportation. The shift from discretionary enforcement to legally binding obligations means that environmental compliance is no longer optional – it is a prerequisite for continued operation. Quarry operators and aggregate producers who fail to meet the new standards face escalating penalties, including fines, license revocation, and legal liability. At OCP Mechanical Company, with over 40 years of manufacturing experience, we supply a comprehensive range of crushing, screening, and sand making equipment – including PE Series jaw crushers, HST Series cone crushers, and VSI 6X sand making machines – designed to help operators meet the new compliance standards while maintaining productive, cost-effective operations, all at factory-direct prices.

Sub‑10mg/m³ dust emission standard – the new survival baseline for sand operations

The Code imposes strict limits on dust emissions from mining and processing operations. Under Article 217 of the Code, mining and mineral processing enterprises must strengthen refined management and adopt measures to strictly control the emission of dust and gaseous pollutants. Article 243 requires that materials such as sand, gravel, and iron ore be stored in enclosed facilities or covered with effective measures to prevent dust pollution. For the sand and aggregate industry, the practical implication is clear: dust emission concentrations must be brought down to sub‑10 mg/m³ levels – a standard that significantly exceeds previous requirements. Facilities that fail to meet these standards face immediate production suspension and escalating penalties. This is not an aspirational target; it is a legally binding requirement with enforcement mechanisms that include daily fines, license revocation, and criminal liability for serious violations. For quarry operators, this means that investing in effective dust collection systems is no longer a discretionary upgrade – it is a survival necessity. At OCP Mechanical, our complete crushing and screening plants can be integrated with advanced baghouse filtration systems and dust suppression technologies designed to achieve sub‑10 mg/m³ emissions, helping operators meet the new regulatory baseline while maintaining efficient production.

Green and low-carbon development – a core pillar of the new Code

The Code elevates green and low-carbon development to a core principle, dedicating an entire section to it. Enterprises are required to strictly control greenhouse gas emissions and coordinate efforts to reduce carbon, pollution, and waste while expanding green growth. In the production and processing stages, the industry is required to comprehensively implement energy conservation and consumption reduction, actively promote intelligent, low-energy production technologies and equipment, and phase out outdated, high-energy, high-emission processes. This represents a clear mandate for equipment upgrades. For quarry operators and aggregate producers, investing in energy-efficient crushing, screening, and sand making equipment is no longer just a cost-saving measure – it is a compliance requirement. The Code also establishes mechanisms for ecological product value realisation, allowing operators who invest in green mining and ecological restoration to participate in eco-compensation trading, creating a financial return on environmental investment. At OCP Mechanical, our PE Series jaw crushers and HST Series cone crushers feature energy-efficient motors and optimised crushing chambers that reduce power consumption, helping operators achieve both regulatory compliance and lower operating costs. All product specifications, including capacity and power ratings, are continuously updated; for the latest parameters, please consult our online customer service.

Full life‑cycle compliance – from extraction to transportation

The Code imposes strict requirements across the entire sand production chain. At the extraction stage, operators must implement dust control and soil and water conservation measures, strictly adhere to ecological red lines, and are prohibited from mining in ecologically sensitive areas or nature reserves. Mining development must comply with territorial spatial planning and ecological control requirements. At the processing stage, the Code requires production lines to be equipped with dust collection and wastewater treatment facilities. The use of high-pollution process equipment that has been explicitly phased out by the state is prohibited. Wastewater must be recycled, and clean production and ultra-low emissions are no longer aspirational – they are mandatory standards. At the transportation stage, the Code mandates closed‑conveyor or enclosed‑vehicle transport to prevent spillage, dust, and noise. The promotion of green transport methods such as enclosed transport and belt corridors is mandated. For aggregate producers, this creates a clear imperative to invest in modern, compliant equipment. Crushers, screens, and sand making machines must be designed to minimise dust emissions, enable closed‑loop water circulation, and operate with high energy efficiency. OCP Mechanical’s equipment is engineered to support these requirements. Our PE Series jaw crushers and HST Series cone crushers feature robust sealing systems and can be integrated with dust collection and water treatment systems. Our VSI 6X sand making machines are designed for efficient, low-emission production of manufactured sand, helping operators achieve the clean production standards now mandated by law.

New energy efficiency standards take effect in December – equipment must meet Grade 2 or higher

Adding to the compliance pressure, new energy efficiency regulations will take effect in December 2026. Under the Code’s energy conservation provisions, industrial equipment must meet Grade 2 or higher energy efficiency standards. Equipment that fails to meet these standards will not be permitted for sale or use. For quarry operators, this means that the window for upgrading outdated, high-energy equipment is closing rapidly. The combination of sub‑10 mg/m³ dust limits and Grade 2+ energy efficiency requirements creates a dual compliance challenge that can only be met through investment in modern, high-performance equipment. Operators who delay face the risk of production stoppages, fines, and loss of market access. At OCP Mechanical, our equipment is engineered to meet the most demanding energy efficiency standards, with high-efficiency motors, optimised drive systems, and intelligent controls that reduce power consumption while maintaining high throughput. By choosing OCP Mechanical, operators can achieve both environmental compliance and lower operating costs.

“Compliance is a survival question” – industry leaders sound the alarm

At the August 2026 Sand & Aggregate Industry Ecological Low-Carbon and Quality Transformation Seminar in Dezhou, Shandong Province, China Mining Association President Sun Yu delivered a stark message: “Compliance is a survival question”. The Code represents not just a regulatory change but a fundamental shift in the industry’s operating environment. Sun Yu’s remarks were echoed by industry leaders who recognise that the era of discretionary environmental management is over. The Code’s integration of 10 separate environmental laws into a single, enforceable framework means that operators who fail to meet the new standards will face immediate and escalating consequences. For quarry operators and aggregate producers, the message is clear: investing in modern, compliant equipment is not just a regulatory obligation – it is a strategic imperative for maintaining market access, securing supply contracts, and building a sustainable business.
