Biochar as material, fertiliser, and long-term carbon store.
The same biochar that removes atmospheric carbon also improves soil, strengthens construction materials, boosts feed conversion, and powers next-generation battery anodes.
Crop-specific programmes with documented outcomes.
Results from specific Tongao-supported field applications. Outcomes vary by soil, crop, climate, biochar characteristics and application rate. Field-level methodology and reports available on request.
Reported paddy trials showed average yield increases around 20% (peak 23.4%) and grain protein content up to 27% higher.
At 200 kg biochar/mu, average cluster weight reached 789 g and sugar content averaged 18.56° (peak 21°).
Hundred-bud weight increased by 41.11%; one-bud-one-leaf ratio improved to 81.8%.
Biochar-blended substrates improved water and nutrient retention and reduced soil bulk density.
Beyond agriculture: construction, feed and energy.
- Soil carbon sink
- Natural pH regulation
- Higher water & nutrient retention
- Heavy-metal passivation
- Microbial activation
- 1–2% biochar → ~15% higher flexural strength
- Improved asphalt viscoelasticity
- Better crack, freeze and ageing resistance
- 10–20% lighter building materials
- 0.6% rice-husk biochar → up to +25% body weight
- Strong mycotoxin adsorption
- Gut microbiota modulation
- Reduced methane and ammonia emissions
- Low-cost anode material with capacity potential beyond graphite
- 3D interconnected porous network
- Micropore ion storage + meso/macropore transport
- Stable 3D carbon skeleton for cycle life
