Silicon Processors, Inc. (SPI) was formed in 2003, to be a vehicle for performance of specific niche service requirements for the energy and environmental industries.
At its inception, SPI developed certain proprietary processes, and designed, purchased, and installed equipment to perform operations which would prepare chemical grade silicon metal for use in the growth of pure silicon crystals for use in the photovoltaic chip industry (Solar Collection). The process was so unique and successful that SPI was responsible for preparation of 100% of the chemical grade silicon metal for its customers, which equated to 60% of the United States solar collection industry. Changes in the worldwide silicon industry and transportation streams caused SPI to shift its primary focus away from the handling of silicon metal, however, SPI continues to grow and is currently negotiating with domestic end users on the construction of a second silicon milling facility.
In 2008, SPI completed the development of a process for preparing Trona for use in sulfur removal from coal burning flue gas streams. An expansion of the Trona facility in 2012 doubled the plant's capacity.
SPI's Parkersburg, West Virginia facility also handles more traditional bulk commodities, including coal, aluminum, cement, pipe, sand, and alloy, by rail, truck, and barge.
SPI continues to work on other environmental and energy related products and processes, including conversion of waste rubber products to energy, biodiesel production, and mercury removal.
