HPD: the Plug-Flow technology gold standard in biogas

Fournier’s HPD is an anaerobic digester system that breaks down organic materials in the absence of oxygen. This process is carried out by microorganisms that decompose the material and produce biogas. The biogas can be used as a renewable energy source for electricity, heat, or fuel. The remaining digestate can be used as a nutrient-rich fertilizer.

Key features

4x more than CSTR

High biogas yield – Better digestion efficiency

3x faster than CSTR
