OMEX Environmental supply pHast, a silage additive range aimed at the AD Market to help optimise the silage fed into the anaerobic digestor. Available in both liquid and solid formats for grass, cereal and maize silage and added at crop harvest.

What are Silage Additives for?

  • Dominate the fermentation process with highly efficient beneficial bacteria to overcome the epiphytic bacteria resident on the plant
  • Reduce fermentation losses
  • Increase ratio of acetic to lactic acid
  • Reduce aerobic spoilage
  • Reduce production of ammonia(which interferes with gas production)



Fast Fermentation is key to savings

  • Less energy used
  • Less Protein breakdown
  • Results in more energy in the clamp
  • More energy equals more gas production
