About our Products

SBGx

SBGx is our workhorse.
A two-component blend of +90% purity, milled to specification, globally in use.

Addresses desulphurisation and stimulates hydrogen generation for increases in gas volume and methane content.

ZEOx

ZEOx is our feed grade zeolite, a microporous aluminosilicate.

It aids in anaerobic digestion by immobilising microorganisms and is adjusted to work most optimally with SBGx and SBGx Plus.

SBGx Plus

SBGx Plus is our most recent development, our most technical oxide blend.
It combines cutting edge electrochemical research with our trusted SBGx, by creating a three- component blend of altered charge state.

Adds to the increases generated by SBGx.
Limited supply only.

Reactive Iron Ion Content (RIIC) explained

The most significant and differentiating factor of any Fe-based additive is its Reactive Iron Ion Content (RIIC; Higher = Better). RIIC is a metric, introduced and used by SwissBiogas.com, to reliably project the potential of additives to bind sulfur and to support the growth of methanogens. Based on the RIICs of its respective iron compounds, the RIIC of any additive can be calculated as follows:

RIIC(FeO) = 0.7773 → RIIC(FeO additive) = Content FeO [%] x 0.7773
RIIC(Fe₂O₃) = 0.6994 → RIIC(Fe₂O₃ additive) = Content Fe₂O₃ [%] x 0.6994
RIIC(Fe₃O₄) = 0.7236 → RIIC(Fe₃O₄ additive) = Content Fe₃O₄ [%] x 0.7236
RIIC(FeCl₂) = 0.4406 → RIIC(FeCl₂ additive) = Content FeCl₂ [%] x 0.4406
RIIC(FeCl₃) = 0.3443 → RIIC(FeCl₃ additive) = Content FeCl₃ [%] x 0.3443
RIIC(FeO(OH)) = 0.6285 → RIIC(FeO(OH) additive) = Content FeO(OH) [%] x 0.6285
RIIC(Fe(OH)₂) = 0.6215 → RIIC(Fe(OH)₂ additive) = Content Fe(OH)₂ [%] x 0.6215
RIIC(Fe(OH)₃) = 0.5226 → RIIC(Fe(OH)₃ additive) = Content Fe(OH)₃ [%] x 0.5226
RIIC(Fe₂O₃·3H₂O) = 0.5226 → RIIC(Fe₂O₃·3H₂O additive) = Content Fe₂O₃·3H₂O [%] x 0.5226

Examples:

Additive X: 60% FeO → RIIC(Additive X) = 60% x 0.7773 = 46.6%
Additive Y: 40% FeCl₃ → RIIC(Additive Y) = 40% x 0.3443 = 13.8%
Additive Z: 10% FeO + 20% Fe₂O₃ + 45% FeO(OH) → RIIC(Additive Z) = 10% x 0.7773 + 20% x 0.6994 + 45% x 0.6285 = 50.0%

Remark: RIIC(SBGx) > 60% (Analysis March 2023)
