In this project HoSt realised a digesting installation in the city of Eppeville in France. The industrial digestion installation has a capacity of 35.000 tons per year. HoSt also developed an biogas upgrading installation in this project for upgrading biogas to biomethane.


Location Eppeville, France
Start construction September 2015
Start-up November 2016
Capacity 35.000 tons/year
Input Manure, sludge, vegetables waste, straw and agriculture waste
Digester(s) 2 x 2.281 m³
After-digester(s) 1 x 2.281 m³
Solid feeding input 2 x 80 m³ Solid Feeding System
Pre-storage 100 m³  + 300 m³


  • Injection into the grid
  • Straw line input
  • Large variety of input materials


In this project HoSt realised in Eppeville, France besides the digesting installation also a biogas upgrading system for upgrading biogas to biomethane. The upgrading system has a capacity of 400 Nm3/hr biogas and upgrades the gas to 210 Nm³/hr biomethane. The upgraded gas will be injected into the gas grid.

Capacity 400 Nm³/hr biogas
210 Nm³/hr biomethane
Methane concentration raw biogas 50-55%
Methane concentration product gas > 93% (gas type B)
Efficiency > 99%
