Process Benefits of the AD-Booster Technology Besides the Extra Biogas

  • AD-Boosted Fibers will not form problematic floating layers after they have been through the AD-Booster process.
  • The fibers have a more amorphous and soft structure allowing water content to increase and reduces the energy needed to fully mix the reactor producing the biogas.
  • The concentration of fibers can be significantly increased in the biogas reactors when the fibers have been through the AD-Booster process, thus enabling a significant increase in volumetric productivity of the biogas plant lowering the capital cost of biogas plants.
  • Overall reduction of operational costs associated with a high concentration of fibers throughout the biogas plant such as cost for mixing.
  • With an AD-Booster, fibers from manure, straw, and grass can substitute the need for energy crops and organic additives to increase biogas production used today.

The AD-Booster Technology Enables Sustainability of Biogas Plants

  • Lowering the overall energy consumption associated with fiber handling throughout the Biogas plant.
  • Enables the production of biogas to be 100% based on agricultural waste materials.
  • Higher volumetric productivity, giving a better utilization of installed production capacity and lowering of the capital cost of biogas plants.
  • Enables fractionation of phosphor between different effluent streams, thus enables better fertilizer management for the farmer.
  • Recover parts of the nitrogen in the raw material as ammonium sulfate, which can be used for designing specific fertilizer fractions or marketed separately.
  • Excess energy from the AD-Booster provides heat for the biogas process, thus reducing or elimination the need for adding process energy to operate the plants.
