Treehouse California Almonds and Sitos Group are building a $9 million slow pyrolysis biochar facility in Delano, California. The plant will process almond shells from Treehouse's hulling and shelling operations into biochar, a stable carbon material that can improve soil moisture retention and nutrient holding capacity. It is expected to be fully operational by the end of 2025. The 25,000 square foot facility will handle 6,000 pounds of almond shell feedstock per hour and use three slow pyrolysis units. Organic Rankine Cycle generators will capture heat from the process and turn it into electricity for the local grid. The project is currently funded by private investment and later through New Markets Tax Credits. Biochar accounts for about 93 percent of carbon removals in the durable carbon market, according to Inside Climate News. The Delano facility is positioned as a commercial example of agricultural co-products becoming a carbon removal tool, with potential soil health benefits for almond growers.

Good example of ag waste turning into a durable carbon product. Almond shells usually go to animal feed or low value uses. 6,000 lbs per hour feedstock is meaningful, and the ORC units feeding the grid add a second revenue stream. Worth watching whether the carbon credits actually get verified.

Sitos says 125k tons CO2 removed globally by durable carbon market, with biochar at 93 percent. That stat is from Inside Climate News and it shows how early this market is. A single facility like this won't move the global number much, but it's the kind of local project that builds supply chain experience.

The Organic Rankine Cycle part is the most interesting detail. Slow pyrolysis gives off heat, and turning that into electricity for the local grid is better than just flaring it. Would like to know the actual output in MW and whether the interconnection queue was an issue. The press release skips those numbers.

New Markets Tax Credits are a solid fit here, but the article says private investment now, tax credits later. That sequencing matters. If the credits are expected to refinance the project, the actual economics depend on award timing and basis. Biochar carbon removal also needs clear accounting to make credits work. Good project, but policy details will decide how scalable it is.

Turning almond shells into biochar makes sense for soil health, especially in California's degraded ag soils. The real question is payback. Biochar has value as a soil amendment, plus carbon removal, plus the heat-to-power side. If the $9M facility only processes 6,000 lbs per hour, they need strong offtake agreements for biochar and electricity to justify it.
