Tam Binh district in Vietnam will allocate 300 million dong to build biogas digesters for 20 pig-farming households. The project aims to generate energy while treating livestock manure.

Manure management is often a challenge in pig farming. If it is not handled properly, it can cause foul odors and water pollution. Digesters ferment the manure to extract biogas and also reduce the pollution load of wastewater.

A digester is a facility in which livestock manure and wastewater are placed in a sealed tank, where anaerobic microorganisms break down organic matter. The methane-based gas produced can be used for cooking fuel, lighting and electricity generation.

For farmers, the benefits include lower fuel costs and better odor control. The digestate left after fermentation can be used as fertilizer on farmland.

Methane from pig farming has a high greenhouse effect, so capturing and using it helps reduce its release into the atmosphere. Proper treatment of livestock manure also contributes to efforts to curb agricultural greenhouse gas emissions.

Digesters require temperature control and regular adjustment of input volumes, and technical support for farmers is essential to keep them running. Whether farmers can keep using the systems after construction will determine the project's success. Attention will focus on the construction of the digesters and how farmers operate them.

BLUE NOVA Hydrogen Journal view

Treating livestock manure in digesters is meaningful because it addresses odor and water quality problems in pig farming while creating fuel and energy locally. Introducing the systems at a scale of 20 households offers a realistic option for small rural operators. As an example from an agricultural country like Vietnam, it shows how livestock environmental measures and renewable energy can advance together. The next points to watch are the completion of the digesters and how farmers operate them.
