Plantd Co-founder, Huade Tan: Innovating Carbon Capture With Building Materials

Huade Tan, co-founder and CTO of Plantd, joins me to explain how two former SpaceX engineers ended up building carbon-capturing structural panels out of a North Carolina tobacco field. The conversation covers how Plantd chose its plant feedstock, why the team deliberately passed on the carbon-credit market in favor of a real product business, and what five years of hardware iteration looks like when you're building an industrial press that hasn't been attempted by a US company since the 1960s or '70s. Huade walks through the full process, from cloning a sterile perennial grass to harvesting it with a modified tobacco harvester to pressing it into finished building panels, and shares the numbers behind the business: $40 to $45 million raised from seed through Series B, and a 2024 deal with national homebuilder D.R. Horton to supply 10 million panels for roughly 90,000 homes. What sets this episode apart is how directly Huade connects his engineering background at SpaceX to the problems he's solving now, including a five-step framework for building hardware that the team is still applying today. It's a grounded, technical look at what it takes to build a genuine hardware moat in an industry that hasn't seen real innovation in decades Timestamps: 00:00 Cold open 00:23 Thank you to our sponsors: NC Idea, Ballentine, Bank of America01:31 Welcome to the episode: introducing Huade Tan and Plantd01:57 The pitch: two SpaceX engineers, carbon capture, and plywood-like panels03:34 Huade joins the show04:01 Huade's background: building life support systems for Crew Dragon at SpaceX05:27 Education path and Nathan's aerospace background06:39 Why North Carolina: population growth trends since 201807:34 From Crew Dragon's "bubble" to the idea for Plantd10:14 The founding question: what do you build from captured carbon?12:23 Why Plantd passed on the carbon credit market14:14 What didn't work early on16:03 The market gap: moisture damage in existing building materials17:15 Simplifying it: how a plant becomes a structural panel19:00 Finding the right fiber: hemp, wheat straw, bagasse, and more21:15 The perennial grass: sterile, cloned, and drought-resistant24:01 400–500 acres established in North Carolina tobacco fields27:22 Harvesting and the strander: turning stalks into fiber29:48 Inside the press: resin, heat, and pressure30:37 Press specs: 15 feet wide, 70 feet long, a quarter-million panels a year37:09 The 5-step SpaceX engineering framework39:43 Funding: $40–45 million raised, seed through Series B41:21 The D.R.
