Engineered biomass-derived tar for industrial materials, energy and carbon applications. Agricultural residues, through controlled thermal conversion, become a traceable industrial feedstock — measured, classified and matched to application.
SPX-BIO-TAR™ is a family of biomass-derived tar fractions produced during controlled thermal conversion of agricultural and other approved biomass residues. Depending on the process, operating conditions and downstream separation, the resulting tar can have significantly different physical and chemical characteristics — so SPX-BIO-TAR™ is classified by application priority and measured specification, rather than treated as one universal product.
Capture the carbon. Characterise the material. Match it to the application.

These are application grades, not an assertion that 100 is inherently “better” than 30. The final grade is assigned only after defined laboratory testing and qualification for its intended use.
The testing specification is developed around the actual intended end use, rather than assuming one universal bio-tar specification.
Selected biomass-derived tar fractions as a component of industrial binder systems — material bonding, aggregate binding, industrial formulations, biomass-derived construction materials. Actual performance is established through application-specific testing.
Pathway: Biomass → Thermal conversion → SPX-BIO-TAR → Formulation/conditioning → Industrial binder
A research pathway for appropriately characterised bio-tar fractions in bituminous or alternative binder systems — testing adhesion, viscosity, softening behaviour, water resistance, durability and mechanical performance. Marketed as a material-development application, not a direct bitumen replacement.
Pathway: SPX-BIO-TAR → Material formulation → Laboratory testing → Mechanical & durability testing → Field trial → Commercial qualification
Selected tar fractions investigated for industrial coating formulations across construction materials, industrial surfaces, wood protection and water-resistant/corrosion-protection formulations, subject to applicable safety and performance requirements.
Pathway: SPX-BIO-TAR → Coating formulation → Applicable-standard testing → Qualified coating
Bio-based protective treatments for appropriate materials — investigating water resistance, surface durability, biological resistance, adhesion and weathering performance.
Pathway: SPX-BIO-TAR → Formulation → Surface treatment → Material protection
Certain tar streams may have combustible properties, but not every grade is sold as a fuel — a dedicated grade is developed only where heating value, viscosity, ash, contaminants and handling characteristics suit a defined thermal system.
Pathway: SPX-BIO-TAR 70 → Conditioning → Burner/thermal system qualification → Industrial heat
One of the higher-value SPX-BIO-TAR pathways — separation, chemical characterisation, fractionation/upgrading into chemical intermediates such as carbon-rich intermediates, aromatic compounds, phenolic fractions and specialty chemicals.
Pathway: SPX-BIO-TAR 90/100 → Separation → Chemical characterisation → Fractionation/upgrading → Chemical intermediates
Investigating bio-tar-derived components in resins, composites, panels and engineered materials — moving the product from a low-value by-product toward a higher-value material feedstock.
Pathway: Biomass → SPX-BIO-TAR → Chemical modification → Bio-based resin → Composite material
Selected streams investigated as precursors or additives in carbon-material development — activated carbon, conductive materials, adsorbent materials and composite additives, each requiring application-specific laboratory validation.
Pathway: SPX-BIO-TAR → Thermal/chemical treatment → Carbon-rich material → Advanced material applications
SPX-BIO-TAR™ is one component of the complete NZLoop system — a multi-product biomass refinery model rather than dependence on a single product.
Pathway: Agricultural waste → Pyrolysis/thermal conversion → SPX-BIO-OIL + SPX-BIO-TAR + SPX-BIOCHAR + SPX-SYNGAS → Multiple markets
Material requirements → candidate grade → laboratory characterisation → formulation development → performance testing → pilot-scale trial → field validation → commercial qualification.
Agricultural residue → SPX thermal conversion → SPX-BIO-TAR → conditioning/formulation → industrial application → digital product passport, so the customer can track origin and measured properties.
Biomass collection → FPO/Mandi → SPX processing → Bio-Oil + Bio-Tar + Biochar + Energy → multiple commercial markets — the farmer does not need to find a market for residue independently.
The exact composition and properties depend on the feedstock and thermal-conversion technology — SPX avoids treating “bio-oil” and “bio-tar” as universally fixed chemical products.
SPX-BIO-TAR™ is not marketed as a direct substitute for conventional bitumen, a universal fuel, or an automatic carbon-credit generator. Carbon-credit eligibility is assessed separately under an applicable recognised methodology rather than assumed from the existence of a Bio-Tar Passport.
SPX-BIO-TAR™ grades are application-specific materials whose suitability is established through defined specifications, laboratory testing and customer qualification.
SPX-BIO-TAR™ is Soil Passport's engineered biomass-derived tar product platform — controlled thermal conversion of biomass into a dense, viscous material for industrial applications, produced as application-specific grades.
Lignin-rich biomass and forestry residue, processed through controlled thermal or carbonisation conversion.
Core applications include industrial binders, sealants and adhesives, displacing petrochemical-derived tar. Potential applications include asphalt/bitumen-related research and construction composites, subject to product testing and specification.
SPX-BIO-TAR™ is produced across 8 application-specific grades, each qualified through defined specifications and laboratory testing.
Construction and materials applications are treated as potential, not core, until backed by product testing and specification for the relevant use case — we avoid claiming a validated application before that qualification work is done.
A traceability record for each SPX-BIO-TAR™ batch, documenting feedstock source, conversion process and grade specification.
