The semiconductor industry is thriving and essential for Taiwan's economic growth. However, the disposal of large quantities of spent sulfuric acid has become a pressing environmental problem in Taiwan. In 2018, the founder of SAR technology Inc. (SAR tech.) saw this problem and built the world's first electronic-grade sulfuric acid circulation plant in Tainan, Taiwan, to regenerate the spent acid to e-grade sulfuric acid and solve this problem for Taiwan’s semiconductor industry. Our online QC/inventory system guarantees the highest quality and timely delivery of our e-grade sulfuric acid to our customers. With our innovative e-grade sulfuric acid regeneration technology combined with online analysis and logistics management, we can provide e-grade sulfuric acid lease services to our customers so that they can use our e-grade sulfuric acid with peace of mind. Under our leasing model, SAR tech. maintains the ownership of fresh sulfuric acid and spent acid, and our customers have the right to use and enjoy our services. Our leasing model ensures a continuous flow of highest quality sulfuric acid, eliminates the risk of over-storage and improper disposal of spent acid, and reduces the environmental impact. This will significantly reduce customers waste inventory, carbon emissions, water use, and operating costs to reach the higher ESG milestones.
