ESGL Submits Provisional Patent Filing, Bolstering IP for Commercialized Precious Metal Recovery Technology

SINGAPORE, Oct. 08, 2025 — ESGL Holdings Limited (NASDAQ: ESGL), a leading carbon-neutral, innovative enviro-tech enterprise focused on converting industrial waste into circular products, has submitted a patent application (reference number 10202502909X) to the Intellectual Property Office of Singapore (IPOS). This filing, made through its subsidiary Environmental Solutions Asia Pte Ltd (“ESA”), aims to safeguard its proprietary technology for recovering precious metals from acidic waste streams.

This provisional patent application stems from over two years of intensive research and development, which has led to the successful commercial deployment of the technology. This commercialization involves extracting precious metal concentrates from semiconductor acid waste. The distinct process integrates high-temperature treatment with advanced resin systems to achieve efficient recovery while minimizing environmental impact. Subsequently, these concentrates are 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. “By turning semiconductor waste into valuable precious metal concentrates, we’ve proven that innovation can go hand in hand with sustainability and economic value creation.”

According to Market Research Future, the global market for recovering precious metals from e-waste was valued at US$20.76 billion in 2024 and is projected to expand consistently through 2032. This growth is anticipated to be fueled by demand from the electronics and semiconductor sectors. The Asia Pacific region is expected to lead this expansion, supported by robust manufacturing activities and an expanding recycling infrastructure. This presents a substantial market opportunity for ESGL to engage with and integrate into the value chain of precious-metal recovery, particularly within high-value acid-based waste streams.

This achievement highlights ESGL’s ongoing dedication to innovation, sustainability, and enhancing shareholder value. Building on this success, ESGL intends to further investigate prospects for applying its recovery technology across various industrial sectors.
