Newtrient Comments/Opinions:

Anaerobic Digester technology:

  • Is proven technology for odor, GHG and pathogen reduction and energy production
  • Has a long usable life and can be run reliably
  • Require proper preparation of the feedstock
  • Usually requires other technologies for energy utilization
  • Usually requires other technologies for digestate handling
  • Proper feeding & system monitoring is required to avoid system downtime
quasar has 15 operational digesters, each of which accepts a wide variety of organic feedstocks.  Several of these digesters accept dairy manure as part of the feedstock blend. quasar’s systems are mechanized and automated which minimizes direct labor requirements. There is limited data available on the capital and O&M costs as quasar systems are typically built, owned and operated by quasar. Newtrient will continue to work with quasar to further refine the cost and performance information as more information comes in with new commercial dairy installations.
