Practice of Architecture: Todd Thomas on diverting 41 million tons of wood waste


2026

Hello Reader,

I sat with a consultant this week whose work crosses our industry and a handful of adjacent ones. She said something I have been trying to push back on and cannot. Architecture firms turn down outside expertise on the firm itself in a way other industries don't. Not the projects, not the buildings, the practice.

We are the profession that brings in specialists for everything. A window detail, an envelope study, a code review, a community engagement plan. And then we treat the work of running and rethinking the firm as the one thing we are supposed to figure out alone. It is closer to a habit than a discipline.

This week's episode names a version of that habit at the other end of a project. Todd Thomas isn't an architect. He's the founder and CEO of Woodchuck, a technology platform using AI to identify, sort, and divert wood waste at industrial scale. The numbers he names are hard to look away from: 41 million tons of wood sent to U.S. landfills every year, accounting for nearly 40 percent of all landfill volume, and when that wood breaks down it produces methane, which is roughly 80 times more potent than carbon dioxide.

His argument is one architects need to hear from outside the profession. If we keep treating waste as an afterthought, we never change the math on sustainability.

The harder ask underneath that is for architects to start designing for deconstruction long before a project breaks ground, and to do it in partnership with the technologists and operators who can actually move the materials when the building comes down.

A big thank you to Pirros for supporting Practice Disrupted on this episode.

One more thing before you go. We are in the final stretch for Innovation in the Built Environment at the University of Michigan's Taubman College. If the question of what architects build, and who else needs to be in the room while we're building it, has been sitting with you, hit reply or reach out to me directly. I can pass along a last-minute discount before registration closes on Tuesday evening.

Where in your firm are you still treating the end of a building as someone else's problem?

Keep learning and growing,

From Trash to Power: Diverting Construction Waste at Industrial Scale

In this episode of Practice Disrupted, Evelyn Lee ventures into the construction and manufacturing side of the built environment to speak with Todd Thomas, founder and CEO of Woodchuck. While the podcast typically focuses on architectural practice, Todd’s work at the intersection of AI and sustainability offers a glimpse into a future where waste is no longer an afterthought, but a valuable commodity.

Hello Reader, NCARB just released the 2026 edition of NCARB by the Numbers. It is the fifteenth. For fifteen years, the profession has been able to see the path to licensure plainly: too long, too rigid, quietly losing people we should have kept. For most of those years we argued about it and changed little. What is different now is that the numbers are finally reshaping the path itself, into something more flexible and modular, built around where the data says people actually fall out. This...

Hello Reader, The story we keep telling about AI in practice is that it makes the work faster. Draw it faster, document it faster, and get the deliverable out the door faster. That might be the least interesting thing it does. The more useful thing, and the one almost no firm is built to use, is that it makes us question something we stopped noticing a long time ago: why are we still working the way we always have? It's the question I kept circling in this week's bonus episode, a conversation...

Hello Reader, My latest episode of Practice Disrupted is about AI closing the gap between a sketch and a built thing. I sat down with the team behind Trimble's 0-60 program and Formas.AI, and we discussed how quickly those tools are moving. /// Listen Here: Closing the gap between sketch and build, with Trimble 0-60 and Formas.AI. But the tools were never the part that kept me up. The harder question is what happens to the practice around them. Practice of Architecture is a business in...
