About TerraNusa Biochar
TerraNusa Biochar is the biochar division of PT Nusantara Karbon Lestari, building on over 15 years of coconut-shell charcoal manufacturing and export experience across more than 20 countries. From our facility in Magelang, Central Java, we transform renewable coconut shells — plus palm kernel shells and wood residue — into high-quality, carbon-negative biochar.
Coconut-shell feedstock delivers exceptional fixed carbon, low ash, and a stable aromatic carbon structure, making it a premium choice for both soil enhancement and durable carbon dioxide removal. We combine deep feedstock knowledge with controlled pyrolysis and rigorous, lab-verified quality control to serve agriculture and carbon-removal buyers across Europe, North America, and beyond.
Indonesia is the world's leading exporter of coconut-shell charcoal — roughly 37% of global shipments — giving our supply chain unmatched scale and traceability.
Backed by an established charcoal export operation with proven logistics, international compliance, and long-standing supplier relationships.
