Microsoft has appointed Trista Brown as its director of zero waste.

Brown was previously the global sustainability program manager at the cloud and enterprise IT company.

On LinkedIn, Brown said that she was "really excited about what's ahead for our team as we break new ground in circularity, waste reduction, and diversion... as we deliver on Microsoft's ambitious commitment to achieving zero waste by 2030."

The company announced that commitment back in 2020, at the time declaring that it would build 'Circular Centers' near its largest data centers to recycle data center components.

Earlier this year, Microsoft also invested in a rare earth materials startup focused on recycling hard drives, Cyclic Materials, as well as waste sortation company AMP.

Other investments made by Microsoft’s Climate Innovation Fund include carbon capture firms CarbonCure, Climeworks, and Heirloom; low-carbon steel firm Boston Metal; microgrid firm AutoGrid (acquired by Uplight); geothermal firm Eavor; battery firm Group14; and Flexidao, among others.
