1. Significant economic cost-effectiveness
1. Lower solvent procurement costs
In traditional cleaning processes, high-purity organic solvents (such as IPA, acetone, NMP, etc.) are often used for single-cycle applications, resulting in significant consumption. Solvent recovery machines employ technologies like distillation and rectification to recycle used waste solvents, purifying them to over 99% purity with recovery rates typically reaching 95%. According to industry data, large wafer fabs may consume hundreds of tons of solvents annually, while the payback period for recycling equipment investment usually ranges from 1 to 2 years.
2. Reduction in hazardous waste disposal costs
• Waste solvents are classified as hazardous waste, with high disposal costs (ranging from several thousand to tens of thousands of yuan per ton). Recycling significantly reduces the volume of waste liquid generated, directly lowering the comprehensive costs of hazardous waste treatment, transportation, and storage.
3. Operational Cost Optimization
• Reduce the frequency of solvent procurement and inventory pressure, lowering supply chain management costs while mitigating the risk of production disruptions due to solvent shortages.
2. Improvement in Production and Operation Stability
1. Quality Consistency Assurance
• The recycled solvent can achieve electronic-grade purity, meeting the stringent requirements for solvent purity in wafer cleaning and avoiding wafer contamination caused by solvent quality fluctuations.
2. Reduction of supply chain risks
• Reduce reliance on external solvent suppliers, ensuring a certain buffer capacity during supply shortages or price fluctuations.
3. Continuous Improvement in Production
• Prevent production halts caused by insufficient hazardous waste treatment capacity or transportation restrictions.
The use of solvent recovery machines in the wafer cleaning industry is a typical win-win solution for "cost reduction and efficiency improvement + green manufacturing." For wafer fabs or cleaning service providers with monthly solvent consumption exceeding one ton, the economic benefits are already very clear. Meanwhile, against the backdrop of increasingly stringent environmental policies and rising ESG requirements, solvent recovery has become an industry standard technology, holding strategic significance for enhancing corporate competitiveness. Companies are advised to conduct a technical and economic assessment based on their scale, solvent usage, and environmental requirements before making decisions.
