About our Products

Introduction

With global population on the rise, an increasing focus rests on agriculture, livestock, water and sustainable energy generation.


Biogas from anaerobic digestion (AD) will lead a key role in the responsible management of the world’s limited resources.


SwissBiogas.com assists AD-plants in the implementation of a sustainable desulphurisation process, minimising their environmental footprint.

SBGx by SwissBiogas.com

High purity tailor-made iron-based additives, which optimise bioreactor environments.

  • Remove Hydrogen Sulfides
  • Increase Biogas and Methane Yields
  • Reduce Odor Formation
  • Address Struvite Formation


SBGx by SwissBiogas.com incorporates the latest research in the field, with the focus to substrate-independently raise the biogas volume and its methane concentration.

Support for beneficial bacteria

  • Biogas production
    In biogas plants, methanogens decompose organic substances in the absence of oxygen. The resultant biogas contains levels of hydrogen sulfides, requiring removal prior downstream processing.
     
  • H₂S removal
    Plant operators apply one of various methods, each with their associated costs and benefits.
    For more details see Methods of desulphurisation compared below.

Introduction of the Reactive Iron Ion Content (RIIC)

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:

  1. Additive X: 60% FeO → RIIC(Additive X) = 60% x 0.7773 = 46.6%
  2. Additive Y: 40% FeCl₃ → RIIC(Additive Y) = 40% x 0.3443 = 13.8%
  3. 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 June 2022)
