What do you do when none of the machinery you imported works? If you're Releaf, you build your own nutcracker, name it Kraken, and get it working with about six weeks of runway left in the middle of COVID. And once you have a huge pile of palm kernel shells sitting around, why not get really into biochar?

Today's guest is Uzoma Ayogu, cofounder and CTO of Releaf and cofounder of Biochar Industrial Group (BIG), which just closed a $1.5 million pre-seed. Releaf cracks palm nuts from smallholder farms in Nigeria, where equipment built for plantations met thick-shelled nuts that arrive wet, dusty and full of rocks. BIG is the carbon dioxide removal side, spun out because Releaf's investors understood agriculture and supply chains and did not understand the voluntary carbon market.

They bought their pyrolyzer from a Ukrainian manufacturer during a war, installed it without the manufacturer's engineer, and Uzo slept in the factory on a yoga mat for two weeks. Uptime went from around a third to 87 percent. We also get into cassava yields, what Y Combinator told them when they got in, and my own YC story, which ends with Nori getting in and saying no.

EcoEngineers: a full-service advisory and consulting firm focused on carbon dioxide removal, decarbonization, and carbon markets.

Listen to the RCC episode I made with David LaGreca from EcoEngineers about how to choose, hire, and fire carbon market contractors.

And the one with Rudy Krehbiel, also of EcoEngineers, on which story carbon dioxide removal is actually in and what it costs to be inside the wrong one.
