Street Calls of the Week
SINGAPORE - ESGL Holdings Limited (NASDAQ:ESGL), a $169 million market cap company whose stock has surged nearly 200% year-to-date, announced Wednesday it has filed a patent application with Singapore’s Intellectual Property Office to protect its technology for recovering precious metals from acidic waste streams.
The application (reference number 10202502909X) follows more than two years of research and development that led to the commercialization of a process that extracts valuable metal concentrates from semiconductor acid waste, according to a company press release.
ESGL’s technology combines high-temperature treatment with advanced resin systems to recover precious metals while reducing environmental impact. The recovered concentrates are later refined into pure precious metals by partner refineries.
"This patent filing marks an important milestone in strengthening the protection of our technology," said Lawrence Law, Executive Director of ESGL, in the statement.
The global precious metals e-waste recovery market was valued at $20.76 billion in 2024 and is expected to grow through 2032, with Asia Pacific projected to lead this expansion, according to Market Research Future data cited in the release.
ESGL Holdings operates through its Singapore-based subsidiary Environmental Solutions Asia Pte Ltd (ESA), focusing on transforming industrial waste into circular products. The company stated it plans to explore additional applications for its recovery technology across various industrial sectors. According to InvestingPro analysis, ESGL currently appears overvalued relative to its Fair Value, though investors can access detailed valuation metrics and 12+ additional ProTips about the company’s financial health and growth prospects through the platform.
