What is Anaerobic Digestion?
Anaerobic Digestion is a process where bacteria break down organic matter in the absence of oxygen.
An Anaerobic Digester is a system made up of airtight tanks that mix and heat organic material resulting in two useful products – biogas, and digestate. These products provide renewable sources of energy and nutrient recovery to the local community and farmers’ fields.

PlanET Technical Container
The PlanET Technical Container is a prefabricated 40’ container with a compact footprint to facilitate easy and cost-effective onsite installation. Enclosed are the critical ancillary components of the digester system:
- Rotary Lobe Pump & Substrate Manifold
- Heating Manifold
- Water Manifold
- Instrument Air
- Oxygen Generator
- Electrical Cabinets/Motor Control Center (MCC)
- Human Machine Interface (HMI)
PlanET Vario Dry Feeder
PlanET’s Vario Dry Feeder introduces solid substrates into the digester. It plays a crucial role in supplying the digester with a consistent and controlled feedstock to optimize the biogas production process while requiring minimal energy. The feeder is distinguished by its modularity and patented conveyor rails that ensure even discharge of the material so it can be sized to suit your application.
