ABOUT

Our History

GSTX, through its QSM affiliate group of companies, is developing an integrated solar materials supply chain spanning high-purity quartz sand, quartz crucibles, silicon metal, polysilicon, monocrystalline silicon ingots, and silicon wafers. The group’s global operations are headquartered in the U.S. and extend to Australia and New Zealand, with planned expansion into Portugal.

The business strategy leverages the team’s extensive industry and professional experience and is driven by a desire for local manufacturing, energy security, supply chain security, driving local industry, and increasing domestic productivity.

Our Philosophy

Making Real Things, Building a Long-Term Sustainable Business.

“What drives us is making real things, adding value, building skills, creating jobs, providing training, and opening up opportunities for the next generation in our communities. All the positive aspects of manufacturing that add to the fabric  of communities where we operate. If we can focus our efforts on a business that aligns with the United Nations’ Sustainable Development Goals, all the better. To this end, renewable solar energy and silicon wafers are our focus.”

“Operationally, our focus is treating people with dignity and respect. Doing better. Not polluting. Making useful products. Adding value. Building communities. Setting the benchmark. Leading with purpose. Being a good corporate citizen. It is easy to label – and dismiss – these concepts as being trendy, or woke. But we prefer to think of these ideals as timeless old-school values. Not new ideas, just concepts many have forgotten, or let go.”

“Growth at all cost is not always a positive thing; people and profits can grow and thrive in harmony. In short, we are all about creating a sustainable long-term business.”
