Waste should not be buried. It should be transformed.

Rather than viewing municipal solid waste, biomass and other discarded materials as liabilities destined for landfills, Sierra Energy’s founders envisioned a technology capable of transforming them into clean energy, renewable fuels and reusable materials. That vision became FastOx^® gasification: a proprietary process built on proven blast-furnace principles and adapted to the modern challenges of waste management, energy security and decarbonization.

The core concept grew from work by former Kaiser Steel engineers Bruce Claflin and John Jasbinsek, who recognized that blast-furnace technology could do far more than produce steel. Sierra Energy acquired the rights to the technology and, under founder Mike Hart, assembled a multidisciplinary team to turn an industrial concept into a commercially viable platform.
