Today, Homerun Resources Inc. announced that its technical partners for the Belmonte Solar Glass Manufacturing Project in Bahia, Brazil, have confirmed that the exceptional purity of the company’s Santa Maria Eterna silica resources allow the production of solar glass 100% free of added antimony compounds. The breakthrough comes as global regulators and recyclers tighten restrictions on antimony, a heavy metal flagged as hazardous even at trace concentrations. Homerun’s high-purity quartz (HPQ) silica, containing less than 20 ppm oxidizable iron ions, enables flawless melting without antimony additives – producing ultra-clear solar glass with superior environmental performance and lower operating costs.
Homerun‘s VP of Operations, Odir Pedrazzi, commented in today‘s news: “Starting our operations without adding antimony represents a decisive economic and environmental milestone for Homerun. By leveraging the exceptional purity of our silica sand resources, we can combine cutting-edge technology with the highest standards of environmental responsibility, positioning the Company as a leader in the global solar glass industry.” CEO Brian Leeners added: “Homerun’s ability to deliver commercial-scale, antimony-free solar glass from Brazil puts the Company at the forefront of a global shift toward safer, recyclable, and ESG- compliant materials.”
- Market tailwind: Global bans and recycling concerns are accelerating
demand for antimony-free solar glass. - First-mover advantage: Homerun is positioned to produce 100% antimony-free solar glass from startup, establishing itself as one of the world’s first large- scale manufacturers of next-generation, environmentally compliant solar glass.
- Same CAPEX, lower OPEX: Equipment and furnace designs already optimized.
- Ultra-pure feedstock: Santa Maria Eterna HPQ silica (<20 ppm iron) enables flawless optical clarity without antimony.
- Strategic positioning: One of the few companies worldwide capable of producing commercial-scale antimony- free solar glass, providing a distinct ESG and competitive edge.
- Today‘s announcement marks a pivotal step in Homerun’s vertical integration strategy and sets the stage for the following analysis on why antimony-free solar glass represents one of the most important technological and environmental advances in the solar industry today.
