Biochar's impact on coffee
+35–40%
yield increase in Brazilian field trials
−20–30%
reduction in fertiliser use through improved nutrient retention
1.5 kg/m²
median effective application rate on acidic tropical soils
NetZero's circular model
NetZero's primary use case in Brazil involves coffee cooperatives. Coffee husk — the abundant residue from coffee bean processing — is converted into biochar at NetZero's production facilities and applied back to the cooperative's member farms.
The result is a fully circular model: coffee husk — once a low-value waste — becomes a high-value soil input that improves soil health, boosts yields, and generates certified carbon credits.
