Corporate Profile: Uwin Nanotech Co., Ltd.
Overview
Uwin Nanotech Co., Ltd. (often referred to as Uwin Technologies in industrial contexts) is a Taiwan-based pioneer in the field of green chemistry and precious metal recovery. Established in 2009 and headquartered in New Taipei City, the company has positioned itself as a global leader in providing environmentally friendly solutions for the recycling of electronic waste (e-waste) and the treatment of semiconductor and PCB manufacturing scrap. The companyâ??s core mission revolves around the "Circular Economy," transforming industrial waste into valuable resources through proprietary, non-toxic chemical processes.

Uwin Nanotech is most recognized for its breakthrough in cyanide-free precious metal stripping. Traditionally, the recovery of gold and other precious metals from electronic components involved the use of highly toxic substances like potassium cyanide or strong acids (aqua regia), which pose significant risks to human health and the environment. Uwin Nanotechâ??s research and development team successfully developed a series of neutral-pH, non-cyanide stripping solutions that allow for the efficient extraction of metals without the hazardous side effects.
Product Portfolio
1. Precious Metal Stripping Solutions
The flagship products of Uwin Nanotech are its chemical stripping agents, categorized by the specific metal they target:
- GP-860 Gold Stripper: A neutral-pH solution designed to strip gold from PCB fingers, connectors, and semiconductor frames. It operates at room temperature and does not damage the underlying base metals like copper or nickel.
- SP-1000 Silver Stripper: An eco-friendly solution specifically formulated to remove silver plating from various substrates without utilizing nitric acid or cyanide.
- Pd-2000 Palladium Stripper: This product targets palladium, which is increasingly common in high-end electronics and automotive catalysts.
- Sn-2000 Tin Stripper: A high-efficiency solution for removing tin and tin-lead alloys from printed circuit boards, facilitating the clean recovery of the copper underneath.
- Ni-3000 Nickel Stripper: Designed to remove nickel plating in a controlled manner, ensuring the substrate remains intact for potential reuse or further processing.
2. Automated Recovery Equipment
To complement its chemical solutions, Uwin Nanotech designs and manufactures specialized hardware to automate the recycling process:
- Automated Gold Stripping Machines: These are integrated systems that use a "soak and rinse" mechanism to process bulk quantities of e-waste. They feature automated chemical dosing and filtration to ensure maximum recovery rates.
- Electrowinning Systems: After metals are stripped into a liquid solution, these machines use electrolytic processes to plate the metal back into solid form (99.9% purity), making it ready for industrial resale.
- Filter Media and Purifiers: The company produces specialized resins and carbon filters designed to capture trace amounts of precious metals from wastewater, ensuring zero-loss operations for manufacturing plants.
Services and Solutions
1. E-Waste Recycling Technology Transfer
Uwin Nanotech does not only sell chemicals; it provides complete "turnkey" solutions for recycling centers. This includes factory layout design, equipment installation, and staff training. Their services enable local recyclers in various countries to establish urban mining operations that meet international environmental standards.
2. Green Semiconductor Manufacturing Support
The company works directly with semiconductor foundries and outsourced semiconductor assembly and testing (OSAT) providers. They offer specialized chemicals for "re-work" processes, where expensive chips or frames can be stripped of plating and re-plated if defects are found during production, significantly reducing material waste and costs.
3. Environmental Consulting and Compliance
Uwin Nanotech assists electronics manufacturers in achieving ESG (Environmental, Social, and Governance) goals. By implementing Uwinâ??s green chemistry, companies can eliminate toxic waste streams, simplify their wastewater treatment protocols, and comply with strict environmental regulations such as the EUâ??s REACH and RoHS directives.
Market Impact and Sustainability
The significance of Uwin Nanotechâ??s technology lies in its ability to facilitate "Urban Mining." By making it safe and profitable to extract gold, silver, and copper from discarded smartphones, laptops, and servers, the company reduces the global reliance on traditional destructive mining practices. Their process is notably low-energy compared to traditional smelting, as it operates largely at room temperature and avoids the massive carbon footprint associated with high-heat furnaces.
In addition to electronics, the company is expanding its reach into the recycling of lithium-ion batteries and catalytic converters, aiming to apply its hydrometallurgical expertise to the burgeoning electric vehicle (EV) market. Through continuous innovation in Taiwan's high-tech ecosystem, Uwin Nanotech remains a critical enabler of sustainable industrial production.
