Faced with increasingly stringent environmental protection policies (such as VOC emission reduction, halogen-free requirements, and upgrading of sewage discharge standards), this solution provides a full-cycle environmental compliance service of “diagnosis – replacement – optimization – certification”. Firstly, it conducts environmental compliance diagnosis on enterprises’ existing production systems, including environmental assessment of raw materials, detection of pollutant emissions from production processes, and analysis of wastewater/waste gas/solid waste treatment efficiency, to accurately locate compliance risk points (such as use of high-VOC solvents, application of halogen-containing flame retardants, substandard wastewater treatment, etc.). Then, it provides green raw material replacement solutions. For example, replacing halogen-containing flame retardants with phosphorus-nitrogen halogen-free flame retardants, replacing high-VOC organic solvents with water-based or plant-based solvents, and replacing traditional non-degradable additives with biodegradable additives. It ensures that the alternative raw materials match the original ones in performance and cost without requiring major transformation of production equipment. At the same time, it optimizes production processes to reduce pollutant generation, such as improving reaction conditions to cut by-product emissions, introducing closed-loop recycling systems to recover solvents and waste heat, and improving resource utilization rate. Finally, it assists enterprises in completing environmental compliance certification, including compiling MSDS, applying for international environmental certifications such as RoHS/REACH, and connecting with local environmental protection departments to complete pollutant discharge permit declaration. It ensures that enterprises fully comply with national and international environmental standards, get rid of the risk of environmental penalties and enhance their green brand image.
