But there are people here in Minnesota working on solutions for managing those emissions. MPR News chief meteorologist Paul Huttner spoke with Paul Dauenhauer, a Distinguished McKnight University Professor at the UM College of Science and Engineering, about the start-up company Carba, of which he is a cofounder. Through Carba, they have developed a proprietary process that converts plant-based waste material into biochar, a stable material that sequesters carbon and can be buried underground for more than 1,000 years ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/climate-cast-316665/episodes/how-a-minnesota-startup-is-taking-carbon-out-of-the-atmosphere/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/climate-cast-316665/how-a-minnesota-startup-is-taking-carbon-out-of-the-atmosphere.md` — Read the agent-friendly Markdown representation of this episode resource.
