High biogas production

Anaerobic digesters from HoSt achieve high process stability, availability, and conversion. Due to our renewed mixer configuration, our anaerobic digesters are capable of running on a high dry matter content. Resulting in a higher output per m3 reactor volume and lower investment costs. Moreover, the risk of silt build-up, drifting layers and foam layers are maximally mitigated. The digesters have in-tank H2S removal, heat recovery, and patented double membrane roofs  – further reducing operational costs. Additionally, Greenstep technology improves biogas production and mixability of the digester.


  • Convert organic waste, organic residues, and manure to biogas
  • Easy to operate due to in-house developed software
  • Lowering of Carbon Intensity score (CI-score)
  • Patented double insulated membrane roofs
  • In-tank H2S removal
  • Ability to run on high dry matter content in the digester
  • Robust plants due to High-quality equipment

AD technology

To achieve maximal flexibilty, HoSt offers various Infeeder systems. Based on the type of feedstock the most suitable system will be selected for the project. The solid feeders are generally placed on weighing cells to ensure an accurate input of products. Additionally, HoSt offers different types of liquid storage tanks. The selection of the best option is based on customer preference, type of waste, and local climate. The tanks can be heated, insulated, and offered in many capacities. HoSt has constructed numerous AD plants worldwide with all types of feedstock and across various industries.
