Product Description

Agricultural On-Farm Anaerobic Digestion Solution – Microferm+

HoSt designed the MICROFERM+ agricultural biogas plant in addition to its product line of biogas plants. Investing in this installation gives farmers the ultimate possibility to use their available manure and agricultural ‘waste’ as valuable feedstock to produce biomethane and to reduce their carbon foot print. It is the turnkey solution for an agricultural biogas plant combined with a biogas upgrading system, using membrane separation technology, and plant control system in a single compact and modular housing.

MICROFERM+ biogas installations are suitable for both liquid waste streams as solid waste streams, which are fed separately into the digester. Depending on the company size and the availability of feedstock, the MICROFERM+ plant is designed to annually anaerobic digest about 5,000 to 10,000 tonnes of agricultural feedstock, such as (cattle) manure, maize silage, grass cuttings and organic waste.

Producing annually a maximum of 550,000 Nm3 biomethane, it can be used by approximately 360 households for cooking and heating for a full year. Left over digestate, the remaining material after the anaerobic digestion process, can be separated or directly stored in an after-storage, to be used as organic fertilizer for crops.




MICROFERM+ installations are combined installations consisting of the biogas system in which solid and liquid waste are fed separately into a digester, and the biogas upgrading system using a membrane separation technology.



The heat recovery heat solution minimizes the own consumption of biogas practically to zero Nm3 per year, allowing to inject more biomethane into the gas grid.


Difference Between Microferm & Microferm+

The main difference between the MICROFERM+ and the Microferm is the size (scale) and ingoing feedstock. The smaller Microferm can produce a maximum of 40 Nm3 of biomethane per hour (40 Nm3 of biogas), whereas the larger scale MICROFERM+ can produce a maximum of 75 Nm3 of biomethane per hour (120 Nm3 of biogas).

HoSt developed the larger scale MICROFERM+ for agriculturists and farmers to use their agricultural ‘waste’ in addition to their available manure as valuable feedstock to produce biogas. Instead, the smaller-scale Microferm manure digesters are designed to process solely manure that is readily available from the own farm.

Another difference between the MICROFERM+ and the Microferm can be seen in the appearance: the pre-treatment and the carbon filters are located outside instead of inside the 40 ft. housing.
