Overview
Carbonized precursors for hard carbon anode production, sourced from three distinct biomass streams to de-risk supply chains and meet diverse customer specifications. PSD-TH uses premium Indonesian coconut shell (2–3 mm wall thickness) carbonized in proprietary PureStar equipment; PSD-ZTH utilizes fast-regrowth bamboo; PSD-TTH repurposes walnut-shell agricultural waste. All grades deliver high fixed carbon with low ash and iron content.

- Biomass carbon research and custom precursor programs
- Power batteries and start-stop systems
Feedstock Flexibility
- PSD-TH: High-density coconut shell delivers superior mechanical strength and carbon yield. Unique carbonization process ensures high strength and low ash of carbonized product.
- PSD-ZTH: Bamboo offers a sustainable, rapid-regrowth alternative with unique pore development pathway.
- PSD-TTH: Walnut shell utilizes agricultural waste streams, supporting circular-economy procurement goals.
- All precursors: Fixed carbon >70%, ash <2–3%, iron <200 ppm—ready for direct conversion to battery-grade hard carbon.
- Multi-feedstock strategy insulates customers from single-source supply disruptions.
