BAYAN SECURES TRANSFORMATIVE PATENTS INSOLAR CELL RECYCLING TECHNOLOGY
Highlights
• Bayan has secured an exclusive license from Macquarie University for“Microwave Joule Heating Technology” a microwave-based solar panelrecycling technology, positioning the company at the forefront of sustainableenergy technology solutions
• The Company intends to commence further research and development to assessthe ability to potentially recover valuable metals such as Silver, Silicon, Galliumand Indium.
• The basis of the technology platform utilises microwave technology to soften theEVA encapsulant in solar panels, enabling easy delamination and potentialrecovery of valuable materials at room temperature.
This approach avoids theneed for extreme heat (1400°C) typically required for separating materials likeglass and silicon as well as the use of costly hazardous chemicals in traditionalprocesses.• Delamination enables selective separation of materials without the need formechanical crushing, whereas traditional crushing methods often result in crosscontaminated material and lower recovery rates.
• The breakthrough technology presents a potential novel pathway forimproved recovery of materials such as silver and silicon from solar panels,critical materials underpinning solar and semiconductor technologies.
• By 2035, Australia is expected to accumulate 1 million tonnes of solar panel wasteworth over A$1 billion1, while the global CIGS (Copper, Indium, Gallium, Selenide)solar cell market is projected to grow to US$12.23 billion by 20322.Bayan Mining and Minerals Ltd (ASX: BMM; "BMM" or "the Company") is pleasedto announce that it has reached an agreement to exclusively licence IP from MacquarieUniversity for its Solar Cell Recycling Technology.
A summary of the material terms ofthe agreement are set out in Schedule 1.
This agreement is a key milestone in Bayan’sstrategic growth, enabling the Company to take advantage of a major economicopportunity in the critical mineral recycling/recovery market.1 Clean Energy Council. 2025.

info@bayanminerals.com.au www.bayanminerals.com.auThe Technology from Macquarie UniversityThe team from the School of Engineering at Macquarie University, led by Dr BineshPuthen Veettil, have developed a new microwave technology that will solve the challengeof electronic waste from end-of-life solar panels.
Currently, the recycling process istechnically challenging with only an estimated 15% of solar panels making it to arecycling facility3, and the remainder going straight to landfill once they have reachedtheir 20–25-year end of life span.
In the rare instance they are recycled, the solar panels,in the traditional method, are crushed and heated at approximately 1400°C before beingwashed in harsh chemicals to remove the plastics.
Dr Binesh Puthen Veettil’s research in collaboration with the School of Photovoltaics atUNSW, the Australian Centre for Advanced Photovoltaics and further supported by theAustralian Government through the Australian Renewable Energy Agency highlights theimmense need and impact this technology will bring.
In this new method, the microwave energy is used to selectively heat the materials withina solar panel. In this process, the silicon cells and other microwave-absorbingcomponents rapidly heat up, while surrounding materials remain relatively cool.
Thistargeted heating causes the plastic encapsulant, ethylene vinyl acetate (EVA), whichholds the panel layers together to soften and degrade.
part of a much larger release
i do not hold this share
this MIGHT ( negatively ) impact silver miners in due couse
( i hold S32 and BHP )
