Package B: Biochar properties

Physicochemical characterization of biochar

Package B provides a detailed physicochemical characterization of biochar. It measures the key properties needed to assess biochar composition, handling behaviour, agronomic suitability, and general material quality.

This package is designed for clients who need a robust analytical profile of their biochar, including carbon content, ash, moisture, pH, electrical conductivity, salt content, water holding capacity, and bulk density.

Package B by itself does not provide Fusinite material verification or Fusinite Lens interpretive reporting. To receive Fusinite Verified material verification and the full Fusinite Lens interpretive report, Package B must be combined with Package A.

What you receive

• General biochar composition and quality profile
• Carbon, ash, moisture, and dry matter assessment
• Organic and inorganic carbon separation
• Reactive and Residual Organic Carbon measurements
• Elemental composition including H, N, S, and O by difference
• H/C_org and O/C_org ratios
• pH, salt content, and electrical conductivity for agronomic and environmental suitability
• Bulk density and water holding capacity for handling, storage, and application planning

Best suited for

• Biochar producers needing routine quality control
• Agricultural and soil application assessment
• Material specification sheets
• Product development and comparison
• Research and development
• Clients who want to combine biochar property testing with Package A for full Fusinite verification

Important

• Package B provides biochar property data, but it does not verify whether the material is genuine biocarbon and does not provide full Fusinite Lens reporting by itself.
• To receive Fusinite Verified material verification and the full Fusinite Lens interpretive report, select Package A + Package B.
• For the fastest route to receive Fusinite Verified material verification, the full Fusinite Lens interpretive report, and a complete carbon permanence assessment, select Inertinite Benchmarking.
