Bayan Mining and Minerals Ltd (ASX: BMM; "BMM" or "the Company") is pleased to announce that it has reached an agreement to exclusively licence IP from Macquarie University for its Solar Cell Recycling Technology. A summary of the material terms of the agreement are set out in Schedule 1. This agreement is a key milestone in Bayan’s strategic growth, enabling the Company to take advantage of a major economic opportunity in the critical mineral recycling/recovery market.
Highlights
- Bayan has secured an exclusive license from Macquarie University for “Microwave Joule Heating Technology” a microwave-based solar panel recycling technology, positioning the company at the forefront of sustainable energy technology solutions.
- The Company intends to commence further research and development to assess the ability to potentially recover valuable metals such as Silver, Silicon, Gallium and Indium.
- The basis of the technology platform utilises microwave technology to soften the EVA encapsulant in solar panels, enabling easy delamination and potential recovery of valuable materials at room temperature. This approach avoids the need for extreme heat (1400°C) typically required for separating materials like glass and silicon as well as the use of costly hazardous chemicals in traditional processes.
- Delamination enables selective separation of materials without the need for mechanical crushing, whereas traditional crushing methods often result in crosscontaminated material and lower recovery rates.
- The breakthrough technology presents a potential novel pathway for improved 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 waste worth 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.
The Technology from Macquarie University
The team from the School of Engineering at Macquarie University, led by Dr Binesh Puthen Veettil, have developed a new microwave technology that will solve the challenge of electronic waste from end-of-life solar panels. Currently, the recycling process is technically challenging with only an estimated 15% of solar panels making it to a recycling facility3, and the remainder going straight to landfill once they have reached their 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 being washed in harsh chemicals to remove the plastics.
Dr Binesh Puthen Veettil’s research in collaboration with the School of Photovoltaics at UNSW, the Australian Centre for Advanced Photovoltaics and further supported by the Australian Government through the Australian Renewable Energy Agency highlights the immense need and impact this technology will bring.
In this new method, the microwave energy is used to selectively heat the materials within a solar panel. In this process, the silicon cells and other microwave-absorbing components rapidly heat up, while surrounding materials remain relatively cool. This targeted heating causes the plastic encapsulant, ethylene vinyl acetate (EVA), which holds the panel layers together to soften and degrade.

Investor Insight
Amid a growing critical minerals sector and supportive legislative agenda, Balkan Mining offers a compelling option to participate in the growing European battery metals market.
Overview
The recent boom in electric vehicle (EV) adoption and green technologies has seen global demand for lithium skyrocket. Analysts believe EV penetration could reach 35% by 2030, which means lithium production will need to quadruple between 2020 and 2030 to satisfy this growing demand.
Lithium production is often associated with countries like Chile, Australia and Argentina — but strategic policy shifts in the European Union have led Europe to look inward for essential battery metals, placing the spotlight directly on the Balkan states. While the Balkan states, which includes Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Kosovo, Montenegro, North Macedonia, Romania, Serbia and Slovenia, are best known for historic gold production — recent lithium discoveries in Serbia have renewed interest in this region.
Balkan Mining and Minerals (ASX:BMM) is focused on an early-stage exploration through the full development of lithium and boron mining in the Balkan region. The company is committed to building an ethical resource portfolio backed by strategic partnerships and guided by an experienced board and management with regional expertise.
The Balkan states, and Serbia in particular, are well-endowed with many minerals and have attracted a surge in foreign investors for the exploration of mining operations. Serbia's Vardar zone is an emerging tier 1 lithium-borate jurisdiction. Balkan Mining and Minerals is well-positioned to capture the growth of the European lithium and boron supply chain.
Balkan Mining and Minerals' flagship Rekovac lithium-borate project demonstrated two successful diamond drill holes discovering preserved lithium and borate mineralization. The company recently completed its surface mapping program. With the success of the initial drilling and exploration, Balkan is well-positioned to commence its drill program in late September 2021.
The company continues to expand its reach across Serbia with four new exploration permits recently granted. The Ursule and Siokovac licenses provide expansion of Rekovac and span nearly 200 square kilometers. The Dobrinja and Pranjani licenses provide access to Western Serbia with favorable lacustrine strata for hosting lithium and boron.
"It's the right region, it's the right commodity and the right capital structure with the right investors… the key thing to add to that is what differentiates this particular lithium project from many of the other … lithium companies, at least listed in Australia, is the borate angle… So that makes these types of things extremely economic and extremely easy to mine and process," commented Ross Cotton, managing director.
Balkan Mining and Minerals is backed by Sandfire Resources (ASX:SFR). The company's current market cap is AU$36 million with 45 million shares on issue.
The leadership of Balkan Mining and Minerals includes a highly commercial board with decades of experience. Sean Murray serves as chairman and brings executive experience from Rio Tinto and expertise in industrial minerals. General Manager Dejan Jovanovic is the Balkan region expert with over 15 years of experience as a geologist. The company has a strong combination of experience and expertise to be a leader in the lithium and boron space.
