Welcome to the Post Pollution Future with LanzaTech

A post-pollution world is inevitable, and people will either be part of it, or the planet will go on without us. At LanzaTech, our technology platform is transforming waste carbon into everyday products, to meet the needs of this moment. Our science is state-of-the-art, but the idea is simple. We use nature to heal nature. We capture carbon emissions which are then fed into bioreactors where trillions of carbon-hungry microbes go to work. These tiny dynamos consume the waste gases and produce valuable raw material commodities. Pure enough to be resold, repurposed, and recycled again — from sustainable jet fuel to beverage bottles, to yoga pants.

Founded in New Zealand, we are a global women-led company with an international footprint and a diverse employee population. Diversity, Equity & Inclusion are a key part of our mission and core values which we show through our hiring, our leadership, our efforts to educate internally and willingness to learn.

In addition, we have announced our plan to merge with AMCI Acquisition Corp. II and expect to become a publicly traded company on Nasdaq. Come join the team as we strive to make a Post Pollution Future!
