The most expensive line item on a vertical farm’s P&L is the electricity to run the lights and climate control. SAVE THE FARMS, a Korean agri-tech startup founded in 2024, is making a bet that the solution to that cost problem is also the solution to a waste problem. Its model is a closed loop: take organic waste, convert it into biochar, capture the residual heat from that process, and use that heat to power an adjacent smart farming operation [LinkedIn, retrieved 2024].
The hardware integration wedge
SAVE THE FARMS is proposing an integrated physical system where the output of one process directly fuels the other. The biochar itself is a marketable product, used as a soil amendment and a carbon sequestration tool. The heat, often a costly waste stream in standalone biochar production, becomes a free input for temperature control in greenhouses or vertical farms. The wedge is efficiency, turning two separate cost centers into a single, synergistic operation.
Early validation and the path to scale
The company is in its earliest stages, with a team estimated at 2-10 employees [LinkedIn, retrieved 2024]. It secured an undisclosed seed round from investors Kingospring and the Infobank Future Environmental Innovation Technology Fund [VentureSquare, Unknown]. It was also selected for two accelerator programs in 2025: the Chungnam Center for Creative Economy and Innovation’s Global Acceleration Support Project and the Ocean-Generation Marine and Fisheries Accelerating Program [VentureSquare, Unknown].

The operational lift and competitive frame
Building and operating combined waste-to-biochar and controlled-environment agriculture facilities requires deep expertise in chemical engineering, thermal systems, and precision horticulture. The company is hiring for an AI researcher and a data scientist, hinting at a focus on optimizing these complex systems [SAVE THE FARMS]. The competitive set includes:
- Biochar producers. Standalone companies like CarboCulture or Pacific Biochar produce biochar but typically do not integrate the heat recovery for agriculture at scale.
- Vertical farm operators. Companies such as Plenty or Bowery focus on efficient growing but source their energy from the grid or renewable PPAs.
- Agricultural waste managers. Large waste management or composting services handle the feedstock but lack the farming operation to utilize the byproduct heat.
SAVE THE FARMS’s ideal customer is an entity that already sits at the intersection of these problems, such as a large food processor with organic waste or a municipality managing agricultural residues. The next twelve months will be about moving from accelerator slides to a pilot facility that proves the energy and cost math in the real world.
