Core Indicators for GRC Project Environmental Acceptance: Ecological Compliance Guide for Green Building Materials

Environmental protection is the lifeline of the GRC industry, with acceptance criteria running through the entire chain of production and construction. Against the backdrop of the "dual carbon" goals and tightening environmental policies, the environmental compliance of GRC projects has become key to project implementation and acceptance. As a national high-tech enterprise and a specialized and innovative enterprise, Qinglong Group upholds the philosophy of "professional innovation and environmental protection," practicing green development across the entire process from material R&D and manufacturing to construction and installation. It provides an in-depth interpretation of the core environmental acceptance criteria for GRC projects, offering a compliance reference for the industry.

#Material Environmental Indicators: Controlling Ecological Attributes at the Source The environmental friendliness of GRC materials is the foundation of acceptance. GRC components produced by Qinglong use eco-friendly raw materials such as low-alkali cement and alkali-resistant glass fibre, with strict control over the content of hazardous substances such as heavy metals and volatile organic compounds (VOC), complying with the Class A standard of "Limits of Radionuclides in Building Materials" (GB 6566). In terms of raw material utilization, recycled aggregates from industrial solid waste are actively adopted. For example, in the Xinjiang River ecological restoration project in Yiyang County, the recycled aggregate content in GRC components reached 30%, reducing resource consumption while lowering carbon emissions. In addition, materials must pass eco-friendly product certification and provide reports on hazardous substance limits issued by authoritative testing institutions.

#Environmental Protection in Production: Strict Control of Pollutant Emissions Environmental management in the production stage is a key focus of acceptance. Qinglong's production base in Nanning, Guangxi, is equipped with a full set of dust recovery systems and wastewater treatment equipment, with dust emission concentration ≤10mg/m³, far below the national standard limit. Production wastewater is recycled after treatment through sedimentation and filtration, achieving zero discharge. In terms of energy consumption control, intelligent production lines are adopted to optimize energy use, with energy consumption per unit of product 18% lower than the industry average. Meanwhile, a production environment monitoring ledger is established to regularly record exhaust gas, wastewater, and noise emission data, ensuring full compliance throughout the production process.

#Environmental Protection in the Construction Stage: Reducing On-Site Environmental Impact Environmental measures during construction directly affect project acceptance results. Qinglong adopts modular construction for GRC component installation, reducing on-site dust-generating operations such as cutting and grinding. Where necessary, measures such as water spraying for dust suppression and enclosed operations are taken to ensure that construction dust concentration complies with the "Integrated Emission Standard of Air Pollutants." In terms of noise control, construction schedules are reasonably arranged and low-noise equipment is used, with nighttime construction noise ≤55dB(A). Construction waste is sorted for recycling; GRC offcuts can be recycled as recycled aggregate after crushing, with a recovery rate of over 90%. For example, the construction waste recycling rate of the Shanghai Xinghewan project reached 95%.

#Completion Environmental Acceptance: Multi-Dimensional Compliance Verification Completion environmental acceptance of GRC projects must cover multi-dimensional indicators. In addition to verifying material environmental testing reports and production and construction environmental ledgers, the durability and environmental stability of components must also be tested to ensure no release of hazardous substances during long-term use. The industry standards that Qinglong participated in formulating clearly require GRC projects to provide an environmental acceptance report, including raw material environmental indicators, pollutant emission data from production and construction, waste recycling status, and other content. Meanwhile, projects must meet the specific requirements of local environmental protection authorities, such as compliant online dust monitoring data and the absence of environmental complaints.

Environmental acceptance of GRC projects is not only a policy requirement but also a reflection of corporate social responsibility. Guided by environmental protection principles, Qinglong Group achieves green compliance across the entire process of GRC projects through technological innovation and refined management, providing owners with architectural decoration solutions that combine aesthetic value with ecological attributes, and driving the industry toward high-quality, low-carbon, and environmentally friendly development.
