Storm Trees combats climate change by turning downed trees into lumber

‘Quit my job and got to work’ to divert from waste stream

What the city of Minnetonka had, McLean said, was “a pile of logs, the better part of the size of a football field, and turns out that they’re paying to get those turned into mulch – and it’s all oak, and ash, and maple and all of this high-value, high-quality material. I was like, ‘What if I told you I’d take all of it?’ I went and bought a truck trailer, skid steer, sawmill, kiln, warehouse, quit my job and got to work on trying to divert some of this stuff from the waste stream.”

Storm Trees acquired its first trees in February 2023 and cut the first boards in the spring of that year. They moved into a warehouse facility on Industrial Drive in northwest Eden Prairie in June 2023. During those intervening months, they temporarily kept the logs on a friend’s Christmas tree farm in Elk River, “which didn’t help us in terms of carbon footprint, because you’re dragging logs 30 miles up the road,” McLean said. 

Using ‘somebody else’s garbage’

Again using the live-edge table as an example, McLean said he and Storm Trees partner and COO Patrick Hughley will build simple projects for customers at this point, but their focus is on lumber.

“It’s time-consuming to pick up trees, mill trees, dry wood,” McLean said. “We’re talking about crazy, crazy hours just getting the wood. I’ve said that I’m like an Uber driver for logs. I’ll get a ping, ‘We’ve got a tree coming down, can you be here in, like, 30 minutes?’” 

The business gets these trees from tree services and municipalities like the cities of Minnetonka and Edina. “They’re often happy to hand over large tree trunks because, ‘A: they don’t necessarily have the home that they used to for the mulch and B: the big stuff is what breaks their equipment,’” McLean said.

Once the tree gets to the warehouse, it is cut into lumber using a sawmill. Whether that’s dimensioned lumber, cut to specific widths and depths – such as 2x4s – or live-edge slabs, which keep the original shape of the tree, depends in part on the species. For white oak, for instance, “Our prospective largest customers are looking for the dimensional lumber,” McLean said, whereas, “Everybody seems to love walnut live-edge slabs, so we’ve got some dimensional, but if it’s a good log, we’ll probably slab some of that as well.” 

After cutting, the boards are dried in a kiln down to 6 to 8% moisture content. The heat treatment cycle provides sterilization from things like insects.
